Advanced Features

This page details advanced features and utilities in the Skip Go client library.

Adding custom messages before or after route execution

The executeRoute method now accepts beforeMsg and afterMsg parameter to allow for the execution of custom Cosmos messages before and/or after the route is executed. This is useful for executing custom messages that are not part of the route definition.

const msg = JSON.stringify({
  fromAddress: 'cosmos1...',  // Replace with sender address
  toAddress: 'cosmos1...',    // Replace with recipient address
  amount: [{
    denom: 'uatom',           // Replace with the actual denom, e.g., 'uatom' for ATOM
    amount: '1000000'         // Replace with the actual amount (in smallest unit, e.g., micro-ATOM)
  }]
});

await executeRoute({
  route,
  userAddresses,
  beforeMsg: { msg, msgTypeUrl: '/cosmos.bank.v1beta1.MsgSend' }
});

Use the Go Fast Transfer system

The route function accepts a goFast parameter to enable the Go Fast Transfers. Then pass this route to the executeRoute method to execute.

import { executeRoute, route } from '@skip-go/client';

const route = await route({
  goFast: true
  ...otherParams,
});

await executeRoute({
  route,
  ...otherParams,
});

Add a fee payer in solana transaction

The executeRoute method accepts a svmFeePayer parameter to specify a fee payer for Solana transactions. This is useful when you want to have a different account pay the transaction fees.

import { Keypair } from "@solana/web3.js";
import nacl from "tweetnacl";
import bs58 from "bs58";
import { executeRoute, route } from '@skip-go/client';


const route = await route({
  // ... other parameters
});

await executeRoute({
  route,
  userAddresses,
  svmFeePayer: {
    address: 'FEE_PAYER_ADDRESS.', // Replace with the fee payer's Solana address
    signTransaction: async (dataToSign: Buffer) => {
      // this is an example the fee payer signer is using a private key
      const privateKey = "FEE_PAYER_PRIVATE_KEY";
      const keypairBytes = bs58.decode(privateKey);
      const keypair = Keypair.fromSecretKey(keypairBytes);
      return nacl.sign.detached(dataToSign, keypair.secretKey);
    },
  }
  ...otherParams,
})
