Make cross-chain swap

Performing a cross-chain swap consists of 4 steps:

1. Routing construction

2. Estimating cross-chain operations

3. Forming data for the transaction

4. Sending the transaction

1. Routing construction

Request routing for the specified tokens and networks

Copy

const requestRoutingParams = {
    params: {
         chainIdIn": 1, // Ethereum
         chainIdOut: 250, // Fantom
         tokenIn: "0xdac17f958d2ee523a2206206994597c13d831ec7", // USDT
         tokenOut: "0xe71286fc887189c562410af12ed521c8e58e5fa3", // s3crypto_e
         amountIn: "100000000", // 100 USDT
    },
    slippage: 1, // 1%
}

const response = await fetch('https://api.crosscurve.fi/routing/scan', {
    method: 'POST',
    body: JSON.stringify(requestRoutingParams),
    headers: {
        "Content-Type": "application/json",
    },
})

const routing = await response.json()

2. Making a route estimate

From the obtained array of routes, take the first route (which is the most profitable for swapping) and send it for estimation

Copy

const bestRoute = routing[0]

const response = await fetch('https://api.crosscurve.fi/estimate', {
    method: 'POST',
    body: JSON.stringify(bestRoute),
    headers: {
        "Content-Type": "application/json",
    },
})

const estimate = await response.json()

3. Forming data for sending the transaction

Copy

const txCreateParams = {
    from: '0x...', // sender
    recipient: '0x...', // recipient
    routing,
    estimate,
}

const response = await fetch('https://api.crosscurve.fi/tx/create', {
    method: 'POST',
    body: JSON.stringify(txCreateParams),
    headers: {
        "Content-Type": "application/json",
    },
})

const rawTx = await response.json()

4. Sending the transaction

Copy

import { Contract, JsonRpcProvider } from 'ethers'
 
const provider = new JsonRpcProvider('RPC_URL_HERE')
const signer = new Wallet(process.env.PRIVATE_KEY, provider)

const router = new Contract(rawTx.to, [rawTx.abi], signer)

const args = [
  rawTx.args[0],
  rawTx.args[1],
  [
    rawTx.args[2].executionPrice,
    rawTx.args[2].deadline,
    rawTx.args[2].v,
    rawTx.args[2].r,
    rawTx.args[2].s,
  ],
]

const value = BigInt(rawTx.value) + BigInt(estimate.executionPrice)

const tx = await router.start(...args, { value })
const receipt = await tx.wait()

Tracking cross-chain swaps

After initiating the cross-chain swap (sending the transaction), it is necessary to ensure that it reaches the destination network and is executed successfully. Each cross-chain swap involves several transactions and the number of transactions may vary depending on the operation.

For swapping two stablecoins from Network A to Network B, the route can be depicted as:

Chain A -----> Hubchain -----> Chain B

Each transaction is linked with another by a unique identifier, requestId, which represents the cross-chain transition identifier and can be used to track the source status and transaction destinations.

Searching for requestId

You can get requestId of a transaction using its hash with the Pusher API:

Copy

const searchParams = new URLSearchParams({
search: '0x...', // transaction hash
limit: 1,
}).toString();
const response = await fetch(`https://api.crosscurve.fi/?${searchParams}`, {
method: 'GET',
})
const result = await response.json()
const details = result.result[0]
const requestId = details.requestId
TypeScript

Getting details about the cross-chain transition by its requestId

Copy

const response = await fetch(`https://api.crosscurve.fi/search?search=%7BhashOrReqId%7D&limit=%7Blimit%7D`, {
method: 'GET',
})
const details = await response.json()
const destination = details.destination
TypeScript

In the results, we are interested in the values of destination.status and destination.transactionHash. If destination.transactionHash is empty, this means that the transaction has not yet been executed and the request should be repeated at intervals until the hash appears.

Then there are 3 scenarios:

1. Both details.inconsistency and destination.emergency are false This scenario is considered the most correct and will occur in most cases. It means the cross-chain operation has been completed and we have the hash of the destination transaction. Now, using this hash, similarly, you can track the status of the next cross-chain transition (if there is one) and continue doing so until all cross-chain transitions are completed.

2. details.inconsistency is true This means that the destination transaction was successfully completed, but the token swap did not occur due to slippage. An intermediate result has been returned to your address in this network. The cross-chain operation is considered complete at this point.

3. The value of destination.emergency is true In this case, the destination network operation could not be executed and your tokens are stuck in the contract. To retrieve them, you need to contact support to request a refund.
