Example Usage

npm install ethers
npm install @sei-js/evm

// Import Wasm precompile address and ABI
// View the entire ABI here: https://github.com/sei-protocol/sei-chain/tree/evm/precompiles/wasmd
import { WASM_PRECOMPILE_ABI, WASM_PRECOMPILE_ADDRESS } from '@sei-js/evm';

import { ethers, toUtf8Bytes, toUtf8String } from 'ethers';

// Using MetaMask as the signer and provider
const provider = new ethers.BrowserProvider(window.ethereum);
const signer = await provider.getSigner();

// Create a contract with the signer
const contract = new ethers.Contract(WASM_PRECOMPILE_ADDRESS, WASM_PRECOMPILE_ABI, signer);

// Replace with your contract
const COUNTER_CONTRACT_ADDRESS = 'sei1eyf...xff';

// Query to get the count on the counter contract (replace with function from your ABI)
const queryMsg = { get_count: {} };
const queryResponse = await contract.query(COUNTER_CONTRACT_ADDRESS, toUtf8Bytes(JSON.stringify(queryMsg)));
console.log(toUtf8String(queryResponse));

// Execute message to increment the count on the contract. (Replace with any function from your ABI)
// No funds are attached since the increment method does not require sei. (Your ABI may require funds)
const executeMsg = { increment: {} };
const executeResponse = await contract.execute(
  COUNTER_CONTRACT_ADDRESS,
  toUtf8Bytes(JSON.stringify(executeMsg)),
  toUtf8Bytes(JSON.stringify([])) // Used for sending funds if needed
);

// Wait for the transaction to be confirmed
await executeResponse.wait();
console.log(executeResponse);

// Execute a message to donate to the contract.
const executeMsg = { donate: {} };

// Funds are attached via overrides. This example is specific to ethers.js
const overrides = {
  value: ethers.parseEther('3.2') // Sending 3.2 sei
};
const executeResponse = await contract.execute(
  COUNTER_CONTRACT_ADDRESS,
  toUtf8Bytes(JSON.stringify(executeMsg)),
  toUtf8Bytes(JSON.stringify([{ denom: 'uusdc', amount: '100' }])), // Also send 100 uusdc
  overrides
);

await executeResponse.wait();
const receipt = await provider.getTransactionReceipt(executeResponse.hash);
