getERC20TokenDetails static method

Future<TokenDetails> getERC20TokenDetails(Web3Client web3client, EthereumAddress tokenAddress)

Retrieves detailed information about an ERC20 token.

This method fetches the name, symbol, and decimals of an ERC20 token using its address. If the provided tokenAddress matches the native token address, it returns a native token with zero amount.

tokenAddress is the address of the ERC20 token.

Returns a TokenDetails object containing the token's name, symbol, decimals, and other relevant details.

Implementation

static Future<TokenDetails> getERC20TokenDetails(
  Web3Client web3client,
  EthereumAddress tokenAddress,
) async {
  if (tokenAddress.toString().toLowerCase() ==
      Variables.NATIVE_TOKEN_ADDRESS.toLowerCase()) {
    return TokenDetails.native(amount: BigInt.zero);
  }
  final toRead = ['name', 'symbol', 'decimals'];
  final token = await Future.wait(
    toRead.map(
      (function) => ContractsUtils.readFromContract(
        web3client,
        'ERC20',
        tokenAddress,
        function,
        [],
      ),
    ),
  );

  return TokenDetails.fromJson({
    'contractAddress': tokenAddress.toString(),
    'name': token[0].first,
    'symbol': token[1].first,
    'decimals': token[2].first.toString(),
    'balance': '0',
    'type': 'ERC-20'
