It contains two stages. The first is to list your NFT and generate a listing id. This is a crucial detail and without it, you wouldn't be able to integrate your widget and sell your NFT. The second phase is the code integration where you'll have to use the generated listing id. It is important to mention that at the moment an NFT widget can only sell one listing at a time. If you'd like to list more than one, you will have to use multiple widgets and integrate them into your website. # NFT Listing Create a listing ID before integrating an NFT widget type. If you chose to implement an NFT widget in your website, this section is very important before you start the integration phase. ### How do I list my NFT? Our widget has the ability to detect your NFTs in your wallet, create a listing and attach it to a certain widget. First, click on 'Go listing' on the customization panel.

This will redirect you to your portfolio page, where you'll need to connect your wallet and see all your NFTs.

On this page, you'll be able to create a listing order by choosing the one that you'd like to sell and defining the price and the time range for the sale.

After you confirm the listing you will be able to see it in the 'Orders' table on the same page and keep track of all your listings.

Now we got to the most important part. The listing ID!

Our system will generate a listing code that you'll need to paste into the widget script during the integration phase. You'll find it in the 'Orders' table. Copy it and save it for our next stage. # Code Integration First, c[reate a `

# Cross-Chain Messaging Protocol An introduction to the bitoftrade's CCMP. Cross-Chain Messaging Protocol (CCMP) provides a universal flow for developers to build secure services and applications that can send messages across multiple chains. CCMP is a quick and easy way to trust events from any chain. It relies on the proof of the event that can be verified and used on any chain. # How it works Cross Chain Messaging Protocol consists of 3 steps: 1. Emit event on the SRC chain 2. Verify the event and get proof from the Signer 3. Receive the event on the DEST chain The key part of the protocol is proof of the event. \ [Signer Service](/for-developers/cross-chain-messaging-protocol/how-it-works/signer-service/signer-interface) is responsible for producing proofs, whereas [Signers Registry smart contract](/for-developers/cross-chain-messaging-protocol/how-it-works/signers-registry-contract) is responsible for validation if proof was made by the correct Signer. # Signer Service Signer service is used to verify specific events. By request the service produces the proof for events. Proof of the event is a signature created by the signer's address. *Under the hood, Signer could implement any protocol to sign messages.* To create an event signature **Signer** signs a specific [`eventHash`](broken://pages/g7yqh32PATsvCWuyRP4n). After the signature was generated, it could be used on your smart contract to verify the event. After successful verification, you could trust this event and do your dApp logic. See the [Signer Interface](/for-developers/cross-chain-messaging-protocol/how-it-works/signer-service/signer-interface) page to get endpoint params to sign the event. You could also interact with our public [Signer](http://20.56.51.41:4000/api/). # Event Hash `eventHash` is calculated from the `eventId` and `eventArgs`: ``` eventHash = keccak256(eventId,eventArgs) ``` `eventId` is the event params combined together to create a unique id. ``` eventId = EventName + EventChainId + EventContract + EventTransactionHash ``` where: * `EventName` - the name of the event * `EventChainId` - chainId of the transaction with invoked event * `EventContract` - a contract that invoked the event * `EventTransactionHash` - hash of the transaction with invoked event `EventArgs` is the event's arguments. All event arguments will be combined in the same order as they were in the event. ``` eventArgs = eventArg_1 + eventArg_2 + ... ``` For example, for [this](https://etherscan.io/tx/0xa3b1123b8181f27c30f9cae42340325f0fcecf80c7886045dc159a8b8abd9a63#eventlog) `Transfer` event, `eventHash` will be: ``` message=keccak256( "Transfer", 1, "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", "0xa3b1123b8181f27c30f9cae42340325f0fcecf80c7886045dc159a8b8abd9a63", "0x974CaA59e49682CdA0AD2bbe82983419A2ECC400", "0x59169f3c0e9e3630D0EBa5E5561dC1677D9451F3", "1574766820" )="0x9d4776df88b0ab9bc77fdd2170fc62ce668886290c49b5306bb003d0a751bdc1" ``` # Signer interface Each Signer implements an interface. ### Metadata ## Get Signer metadata `GET` `https://api-ccmp.bitoftrade.com/metadata` {% tabs %} {% tab title="200: OK " %} ```json { "name": "signer_name", "availableChains": [1, 56, 137], "signer": "0x86f3b7f305f9d02e243a28445a15ecb6eeb12288" } ``` {% endtab %} {% endtabs %} `GET /metadata` the endpoint returns an object with the following type: ```json { "name": "signer_name", "availableChains": [1, 56, 137], "signer": "0x86f3b7f305f9d02e243a28445a15ecb6eeb12288" } ``` Where: * `name` is the human-recognizable name of the signer * `availableChains` is the list of supported chains * `signer` is the address which is used to sign messages ### Sign event ## Get proof of the event `POST` `https://api-ccmp.bitoftrade.com/sign-event` #### Request Body | Name | Type | Description | | ----------------------------------------- | ------ | ----------------------------- | | chainId\* | Number | Chain id of the event | | txHash\* | String | Transaction hash of the event | | abi\* | Object | ABI of the event | {% tabs %} {% tab title="200: OK " %} ```json { "chainId": 1, "txHash": "0xa3b1123b8181f27c30f9cae42340325f0fcecf80c7886045dc159a8b8abd9a63", "eventHash": "0x2d734e2f6520ad47f4fbd40ac2f7fa491c029d1b06916be7ba544e2133d16bb5", "signature": "0xd189b3df1b889c280f4dc84de5aaaf9aaf425838752ff3ceb13234aae17d12f46375420d93181968ce03d02a5069c2d848a2512113d24004db9001ff889d9fa21c", "signer": "0x50fde2a03a1edfd7e1fddeda73d6620a1d0beee3", "params": [ "Transfer", 1, "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", "0xa3b1123b8181f27c30f9cae42340325f0fcecf80c7886045dc159a8b8abd9a63", "0x974CaA59e49682CdA0AD2bbe82983419A2ECC400", "0x59169f3c0e9e3630D0EBa5E5561dC1677D9451F3", "1574766820" ] } ``` {% endtab %} {% endtabs %} `POST /sign-event` the endpoint which is used to get proof of the event.

This smart contract has to be deployed on each supported chain. SignersRegistry implements this interface: ```solidity interface ISignersRegistry { function isPublicWhitelisted(address signer) view external returns (bool); function isPrivateWhitelisted(address signerAdmin, address signer) view external returns (bool); } ``` The signer could be `public` or `private`. * Anyone can use the `public` signer for supported chains. * The `Private` signer could be used for specific dApps, chains, etc. Such signers are restricted and closed for the community. Contact us if you want to implement a private signer. See the [example](/for-developers/cross-chain-messaging-protocol/quick-start/receive-event) to understand how to use Signers Registry smart contract. See deployed smart contract on [explorer](https://polygonscan.com/address/0x3E0387bDcCe1b2A416700FC075f8c33c3A5f7E07#readProxyContract). # Quick start In our example, we covered these steps: 1. Emit event on the [Mainnet](https://etherscan.io/tx/0x9f89aae86d1b69cf63065bfc9f30478b6dc613b4655a857bc115a1275604b88c) chain 2. Get proof of the event from the Signer 3. Receive event on the [Polygon](https://polygonscan.com/tx/0x3b9c04a4d3d0061173be7654724a9114441f125bc5912a4b31e9bb3f39b4223c) chain See [How it works](/for-developers/cross-chain-messaging-protocol/how-it-works) page to better understand protocol flow. # Emit event Cross Chain Messaging Protocol makes it possible to send events between different chains. CCMP relies on the events. To start interacting with it, modify your **Src** smart contract to emit the event. ```solidity pragma solidity ^0.8.0; contract MsgSender { event MyMessage(string message); function sendMessage(string memory _message) external { emit MyMessage(_message); } } ``` You could also add **destChainId** and **destAddress** params to the event to make it more specific. However, none of those are required, and you could pass any parameters depending on your internal dApp logic. See the example of `sendMessage` transaction on the [explorer](https://etherscan.io/address/0x1170490264e8c604e0d0861b76768a9e9a300b02). # Verify event After the event was emitted, the next step is to receive proof of the event. Signer is responsible to create a signature as proof of the event. Create `POST /sign-event` [request](/for-developers/cross-chain-messaging-protocol/how-it-works/signer-service/signer-interface) to the Signer. For our example, the request body would be: ```json { "chainId": 1, "txHash": "0x9f89aae86d1b69cf63065bfc9f30478b6dc613b4655a857bc115a1275604b88c", "abi": { "anonymous": false, "inputs": [ { "indexed": false, "name": "message", "type": "string" } ], "name": "MyMessage", "type": "event" } } ``` As a result of the request, we receive the following object:

{
  "chainId": 1,
  "txHash": "0x9f89aae86d1b69cf63065bfc9f30478b6dc613b4655a857bc115a1275604b88c",
  "eventHash": "0x32b5aaa307499c5f926182bcb425d152e9d17e0c38ad46aecfc8b3007005221d",
  "signature": "0xc7067dbae67fe37d68945b4d32d636c02590d4e0da3dcd87616356178afc3d6b048ea054954bce2e5d2d853e379bc4f8fc16f6c0cb68de50cee844407806e09a1b",
  "signer": "0x86f3b7f305f9d02e243a28445a15ecb6eeb12288",
  "params": [
    "MyMessage",
    1,
    "0x1170490264E8c604E0D0861B76768A9e9a300b02",
    "0x9f89aae86d1b69cf63065bfc9f30478b6dc613b4655a857bc115a1275604b88c",
    "Hello World"
  ]
}

The signature is created, therefore we can move to the last step. # Receive event After the event was made on the SRC chain and verified by the Signer, the last step of the protocol is receiving that event on the **DEST** chain. \ We can trust that event happened on the **SRC** chain if proof of this event was made by the correct signer. [Signers Registry smart contract](/for-developers/cross-chain-messaging-protocol/how-it-works/signers-registry-contract) is responsible for this validation. In our example, to receive the event on the **DEST** chain, we have to call `receiveMyMessage` method on the `MsgReceiver`. ```solidity pragma solidity ^0.8.0; contract MsgReceiver { event MyMessageReceived(string message); ISignersRegistry signersRegistry; constructor(address _signersRegistry) { signersRegistry = ISignersRegistry(_signersRegistry); } function receiveMyMessage( bytes calldata _signature, string memory _message, address _msgSender, uint256 _chainId, bytes calldata _transactionHash ) external { bytes32 eventHash = keccak256(abi.encodePacked("MyMessage", _chainId, _msgSender, _transactionHash, _message)); address signer = eventHash.recover(_signature); bool isSignerWhitelisted = signersRegistry.isPublicWhitelisted(signer); require(isSignerWhitelisted, "Signer is not whitelisted"); emit MyMessageReceived(_message); } } ``` You can check, that [eventHash](/for-developers/cross-chain-messaging-protocol/how-it-works/signer-service/event-hash) was made the same way as Signer did while making the signature. It's very important to recover the signature with the same eventHash. After the signature maker was recovered, `signersRegistry` checked if the signer was whitelisted. That's why all public and private `Signers` have to be whitelisted before producing any event proofs. If `signersRegistry` approved that the signer was whitelisted, it means that we can trust this event. Therefore, do any steps required by your dApp. In our example, it just emits the `MyMessageReceived` event. See the example of the `receiveMyMessage` transaction on the [explorer](https://polygonscan.com/tx/0x3b9c04a4d3d0061173be7654724a9114441f125bc5912a4b31e9bb3f39b4223c). # Smart contracts Signers Registry

# Advanced If you are familiar with CCMP protocol you can dive deeper to better understand how the Signer Service works under the hood. Consider the [Threshold Signature](/for-developers/cross-chain-messaging-protocol/advanced/threshold-signature) section to become familiar with the TSS protocol, which is used by our [Signer Service](/for-developers/cross-chain-messaging-protocol/how-it-works/signer-service). Also, take a look at the [Hosted TSS Signer](/for-developers/cross-chain-messaging-protocol/advanced/hosted-tss-signer) section to know how and why Hosted TSS Signer can be used for your dApp to make it even more secure. # Threshold Signature The threshold signature (TSS) protocol is a cryptographic scheme that allows a group of participants to collectively sign a message or transaction without revealing their private keys to each other. In a threshold signature scheme, the private key is split into several shares, each of which is distributed among the group of participants. To generate a signature, a minimum threshold of participants is required to combine their shares and produce a partial signature. Threshold signature protocols are considered secure because they provide several security guarantees that protect against various types of attacks, such as the compromise of a single participant's private key or the collusion of a group of participants. Our own [Signer Service](/for-developers/cross-chain-messaging-protocol/how-it-works/signer-service) relies on the TSS protocol. This distributed trust model makes it difficult for any one participant or third-party service to compromise the system. Therefore, the Signer Service is reliable and trusted by our clients. # Hosted TSS signer As you know from the previous section, the TSS protocol can be used for the Signer Service to make it even more secure and trusted. Despite the fact that we rely on our Signer Service with TSS protocol run under the hood, we deeply understand your desire to be responsible and host your own independent TSS. Here are some benefits of hosting TSS: * Easily decide amounts of parties and threshold. * Configure it to your own dApp. * It's trusted because you control all parties by yourself. Private Signer Services are still compatible with our [Signers Registry](/for-developers/cross-chain-messaging-protocol/how-it-works/signers-registry-contract), so you don't need to worry about deploying anything else. As an additional service, we provide full documentation and support to help you setup up your TSS. Please [Contact Us](/contact-us) to get additional instructions. # Security CCMP protocol consists of two components: * Signers Registry smart contract * Signer Service Our smart contracts are audited and well-secured. Also, we use [Gnosis Safe](https://safe.global/) as another layer of security to manage all our smart contracts. It helps us make it more trustable and open for the community. Our Signer Service is secured by [TSS Protocol,](broken://pages/K857grhlYgij53B1IplN) making it almost impossible to compromise our signer. You have the option to deploy your [own TSS Signer](broken://pages/xENZ1kqrFf84gfQVpOh0) and configure it to the needs of your dApp. As a result of approaches, the Cross-Chain Messaging Protocol is secured and trusted. # FAQ

Is the service free?

Yes, it's completely free and public. You can use it right now for your cross-chain applications.

Is it secure?

Yes, it is. Our Signer Service uses TSS protocol under the hood to make it almost impossible to compromise our signer.

Why does it exists?

There are a lot of different blockchains and networks. Users need to exchange tokens, NFT, and transfer liquidity. CCMP makes it easy to interact between chains.

How we are different from other solutions?

We are much more friendly than ChainLink or Multichain. You can use our service without any requirements, you don't need to be whitelisted, etc. \ Also, we are free and open to the community.

Staying afloat in the volatile crypto world is largely dependent on your overall understanding of the market. Yes, it can be hard to predict but it’s not impossible! To make accurate market behavior predictions, you need a firm understanding of both fundamental and technical analysis, as well as keeping an eye out for key market indicators and any strategies you can implement. Of course, there are always [bullish patterns](https://bitoftrade.com/blog/top-5-bullish-patterns-for-crypto-trading) and [crypto candles](https://bitoftrade.com/blog/how-to-read-crypto-charts-a-guide-to-crypto-candles) too! **Fundamental analysis.** This analysis includes researching as much as you can about the project, financial, and on-chain metrics. Fundamental analysis is best used to determine a token’s intrinsic value. Once you’ve investigated a token’s background and its creators, you can begin to understand whether the coin represents good market value. For example, is this an industry-changing project? Or, does the analysis suggest a quick decline? By applying these methods and gaining sufficient knowledge, you can make an informed decision. **Technical analysis.** This is based on charts that factor in price changes, order sizes, and turnover values. Technical analysis involves observing the market historically and keeping your eyes peeled for any trends. You can look at trading volumes and any shifts in price! This method is the most efficient way to study how profitable a token may or may not prove to be. By following price variations and patterns, the theory behind technical analysis can be applied to assume both long and short-term price variations. **Indicators:** Market indicators can, mostly, be grouped into four specific categories: Momentum, Volume, Trend, and Volatility. Momentum indicators, such as the Stochastic Oscillator, compare the most recent closing price of an asset against any maximum price variations (high and low) during a defined period. Volume indicators (known as on-balance volume or OBV), meanwhile, use technical analysis to predict any obvious changes in an asset’s stock price. Trend: Moving averages, such as Simple Moving Averages (SMA) and Exponential Moving Averages (EMA), track, quite simply, the average movement of an asset’s price across a specified time frame. Volatility: Bollinger bands (or Boll Indicator), Standard deviation and ATR are three examples of volatility indicators. Volatility indicators are best used to detect potential fluctuations in the market, by highlighting whether or not an asset is being overbought or oversold. For more information about our crypto indicators, please click [here](https://bitoftrade.com/blog/best-indicators-for-day-trading-crypto)**.** **Strategies:** There are four main strategy methods that you can apply when trading: position trading, scalp trading, swing trading, and day trading. Figuring out which works best for you is a simple case of trial and error. Always pick the strategy that suits you best! A **position trade** is close to a buy-and-hold investment strategy. The idea is to capitalize on trends in the crypto market by identifying strong tokens and holding onto them until the time is right to trade, so when you notice a price rise. **Scalping trading** is extremely fast-paced. A crypto scalper can make up to 20 trades in a few minutes, though it takes a lot of energy to do so. As crypto prices can change rapidly, a scalper has to watch for increases in trading volumes and know the exact exit point before even beginning the trade. The key to successful scalp trading is using a trading platform with fast execution times so you avoid lag time. **Swing trades** are somewhat the opposite of scalp trades, as the time frame of a swing trade is usually longer. The idea around swing positions is to spy any ‘swings’ in the crypto market— these can occur over days, weeks, and even months! **Day trading** involves opening and closing asset positions on the same day and is viewed as short-term crypto trading. With day trading, your goal is to increase profits as the price of a token moves - though you should always consult technical indicators to suss out potential entry and exit points. \ You can read more about managing a volatile market in our article [Crypto Prediction Guide: Understand The Market and Predict Future Behavior](https://bitoftrade.com/blog/crypto-prediction-guide-understand-the-market-and-predict-future-behavior). # How to invest in cryptocurrency #### Helpful tips for investing in crypto Are you looking to invest in cryptocurrency? Well, you’ve come to the right place. With our helpful tips, you can start trading crypto in no time! We’ve compiled a list of helpful tips for you to consider before you start investing: **Market research.** You should research all of the tokens you’re planning on investing in, and learn as much about their history and market value as you can. You should also look into the type of trading platform you’d like to use, we have a helpful article about [CEXs vs DEXs](https://bitoftrade.com/blog/dex-vs-cex-know-where-to-trade) to guide your research. **Assess risk.** Trading crypto is exciting and it can be easy to get carried away, so we recommend only investing in what you’re willing to lose. Assess the financial risk before executing any trade as this ensures you don’t make losses you can’t afford. **Using a crypto wallet.** Before you can start trading like a pro, you’ll need a crypto wallet! Think of a crypto wallet as similar to a virtual wallet, except it stores the public and private keys for cryptocurrency transactions. The most popular Ethereum wallet is MetaMask. Check out our handy video on installing below. You can also use your Trust Wallet on our platform. **Diversify your portfolio.** Holding more than one token reduces the risk of losing all of your assets. If you invest everything in one token, and it sees a huge value drop in the market, you risk losing everything. This is why we offer all tokens over multiple networks on our platform—so you’ll have plenty to choose from! {% embed url="" %} For more tips on investing, read our educational articles about crypto: * [How to Trade Crypto Responsibly: Tips for Beginners](https://bitoftrade.com/blog/how-to-trade-crypto-responsibly-tips-for-beginners) * [How to Make Money with Cryptocurrency and Increase Your Profits?](https://bitoftrade.com/blog/how-to-make-money-with-cryptocurrency-and-increase-your-profits) * [Best Day Trading Crypto Strategies 2022: Ultimate Guide](https://bitoftrade.com/blog/best-day-trading-crypto-strategies-2022-ultimate-guide) * [How to Earn Crypto Passive Income](https://bitoftrade.com/blog/how-to-earn-crypto-passive-income) # Polygon # How to swap on the Polygon network #### A step-by-step guide on how to swap tokens on the Polygon network with bitoftrade.

Some networks require a bridge to transfer tokens from one network to another, and Avalanche is one of them! All you need is the [Avalanche Bridge](https://bridge.avax.network/login), to transfer ERC-20 tokens from Ethereum to Avalanche’s C-Chain and vice versa. This may sound a little complicated, but it isn’t! It’s important to know that the bridge doesn’t support native ETH or BTC, so you’ll have to transfer wrapped versions of these tokens (WETH and WBTC) instead. **Important note:** the Avalanche Bridge only allows transfers to the same address on the other network. You can learn how to bridge Avalanche tokens with our simple step-by-step guide below: 1. Connect your wallet using MetaMask or Trust Wallet and log in. 2. Once you have successfully connected your wallet, ensure that the “From” tab shows Ethereum, otherwise press the “Switch” button and click “Switch Network” when your wallet application prompts. 3. Select the assets and enter the amount you would like to bridge across. 4. Click “Transfer” and sign the transaction prompt that pops up on your wallet. 5. Please wait for the transaction to be completed on both Ethereum and Avalanche networks. It takes approximately 10 minutes on the Ethereum side and 30 seconds on the Avalanche side. 6. Once completed, you have successfully bridged your ERC-20 tokens to Avalanche! When moving assets from Avalanche to Ethereum, the bridge fee is largely based on the estimated Ethereum transaction fee. This is calculated using current asset prices, the current Ethereum gas price, and the approximate amount of gas that will be used by the Ethereum transaction. As such, the Ethereum transaction fee and bridge fee can be highly variable. # How to swap on the Avalanche network #### Learn how to swap trading on the Avalanche network with bitoftrade.
