  evmChainId: number | undefined;
  isMainnet: boolean;
  requiredBlockConfirmations: number | undefined;
  maxRetryDurationBlocks: number | undefined;
}

Param	Description	Data type

// console output:
[
  {
    chain: 'Ethereum',
    name: 'Ethereum',
    evmChainId: 1,
    isMainnet: true,
    requiredBlockConfirmations: 7,
    maxRetryDurationBlocks: 0
  },
  {
    chain: 'Bitcoin',
    name: 'Bitcoin',
    evmChainId: undefined,
    isMainnet: true,
    requiredBlockConfirmations: 3,
