In order to use the cosmJS library function in the CrossFi network, you need to patch the cosmJS library as in the example:
const { stringToPath } = require('@cosmjs/crypto');
const { DirectSecp256k1HdWallet } = require('@cosmjs/proto-signing');
const { SigningStargateClient, GasPrice } = 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 = {
mpx: GasPrice.fromString('10000000000000mpx'),
xfi: GasPrice.fromString('100000000000xfi'),
};
const PREFIX = 'mx';
const HD_PATHS = [stringToPath("m/44'/118'/0'/0/0"), stringToPath("m/44'/60'/0'/0/0")];
async function main() {
const clientOptions = {
gasPrice: GAS_PRICE.xfi,
broadcastTimeoutMs: 5000,
broadcastPollIntervalMs: 1000,
};
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();
