Phần Chính Hệ Thống Cosmos

CosmJS

Để sử dụng chức năng thư viện cosmJS trong mạng CrossFi, bạn cần thay đổi thư viện cosmJS như trong ví dụ: https://github.com/crossfichain/js-tx-example

const  = require('@cosmjs/crypto');
const = require('@cosmjs/proto-signing');
const = require('@cosmjs/stargate');
const bech32Converter = require('bech32-converting');

require('dotenv').config();

const COSMOS_RPC_URL = 'https://tendermint-rpc.mainnet.ms';
const MNEMONIC = process.env.MNEMONIC || '';
const GAS_PRICE = ;
const PREFIX = 'mx';
const HD_PATHS = [stringToPath("m/44'/118'/0'/0/0"), stringToPath("m/44'/60'/0'/0/0")];

async function main() ;
const signer = await DirectSecp256k1HdWallet.fromMnemonic(MNEMONIC, { prefix: PREFIX, hdPaths: HD_PATHS });
const signingClient = await SigningStargateClient.connectWithSigner(COSMOS_RPC_URL, signer, clientOptions);
const [oldAddressAccountData, newAddressAccountData] = await signer.getAccounts();
const chainId = await signingClient.getChainId();

console.log('chain id:', chainId);
console.log('old address:', oldAddressAccountData.address); // previous mainnet network
console.log('new address:', newAddressAccountData.address); // current mainnet network
console.log('new evm address:', bech32Converter(PREFIX).toHex(newAddressAccountData.address));
}

main();
