Swap ETH to BTC via deposit channel

import { SwapSDK, Chains, Assets } from '@chainflip/sdk/swap';
 
// Initialize SDK
const swapSDK = new SwapSDK({
  network: 'perseverance',
});
 
// Fetch quote for swap
const quote = await swapSDK.getQuote({
  srcChain: Chains.Ethereum,
  srcAsset: Assets.ETH,
  destChain: Chains.Bitcoin,
  destAsset: Assets.BTC,
  amount: (0.1e18).toString(), // 0.1 ETH
});
console.log('quote', quote);
 
// Request deposit address for swap
const depositAddress = await swapSDK.requestDepositAddress({
  srcChain: Chains.Ethereum,
  srcAsset: Assets.ETH,
  destChain: Chains.Bitcoin,
  destAsset: Assets.BTC,
  amount: (0.1e18).toString(), // 0.1 ETH
  destAddress: 'tb1p8p3xsgaeltylmvyrskt3mup5x7lznyrh7vu2jvvk7mn8mhm6clksl5k0sm',
});
console.log('depositAddress', depositAddress);
 
// Fetch swap status
const status = await swapSDK.getStatus({
  id: depositAddress.depositChannelId,
});
console.log('status', status);

Swap ETH to BTC via Vault contract

import { SwapSDK, Chains, Assets } from '@chainflip/sdk/swap';
import { getDefaultProvider, Wallet } from 'ethers';
 
// Initialize SDK
const swapSDK = new SwapSDK({
  network: 'perseverance',
  signer: new Wallet(
    process.env.PRIVATE_KEY as string,
    getDefaultProvider('sepolia'),
  ),
});
 
// Fetch quote for swap
const quote = await swapSDK.getQuote({
  srcChain: Chains.Ethereum,
  srcAsset: Assets.ETH,
  destChain: Chains.Bitcoin,
  destAsset: Assets.BTC,
  amount: (0.1e18).toString(), // 0.1 ETH
});
console.log('quote', quote);
 
// Initiate swap via Vault contract
const transactionHash = await swapSDK.executeSwap({
  srcChain: Chains.Ethereum,
  srcAsset: Assets.ETH,
  destChain: Chains.Bitcoin,
  destAsset: Assets.BTC,
  amount: (0.1e18).toString(), // 0.1 ETH
  destAddress: 'tb1p8p3xsgaeltylmvyrskt3mup5x7lznyrh7vu2jvvk7mn8mhm6clksl5k0sm',
});
console.log('transaction', transactionHash);
 
// Fetch swap status
const status = await swapSDK.getStatus({
  id: transactionHash,
});
console.log('status', status);

Swap BTC to ETH with Cross-Chain Message

import { SwapSDK, Chains, Assets } from '@chainflip/sdk/swap';
 
// Initialize SDK
const swapSDK = new SwapSDK({
  network: 'perseverance',
});
 
// Fetch quote for swap
const quote = await swapSDK.getQuote({
  srcChain: Chains.Bitcoin,
  srcAsset: Assets.BTC,
  destChain: Chains.Ethereum,
  destAsset: Assets.ETH,
  amount: (0.05e8).toString(), // 0.05 BTC
});
console.log('quote', quote);
 
// Request deposit address for swap
const depositAddress = await swapSDK.requestDepositAddress({
  srcChain: Chains.Bitcoin,
  srcAsset: Assets.BTC,
  destChain: Chains.Ethereum,
  destAsset: Assets.ETH,
  amount: (0.05e8).toString(), // 0.05 BTC
  destAddress: '0xFcd3C82b154CB4717Ac98718D0Fd13EEBA3D2754',
  ccmMetadata: {
    message: '0xdeadc0de',
    gasBudget: (125000).toString(),
  }
});
console.log('depositAddress', depositAddress);
 
// Fetch swap status
const status = await swapSDK.getStatus({
  id: depositAddress.depositChannelId,
});
console.log('status', status);
