swap test case:

  • 使用 uniswap 生成的 data, 然后通过 wallet 再次签名后, 广播出交易.
 test('eth token swap:', () async {
    var privateKey = 'your-private-key';

    var walletAddress = '0x9fe1901f3bb6cd21dca275f5e746409bd4ae8861';
    var contractAddress = '0x7a250d5630b4cf539739df2c5dacb4c659f2488d';

    ///
    var amount = BigInt.tryParse('0x314b3d2e4230000') ?? BigInt.from(0);
    var dataStr =
        '0x7ff36ab5000000000000000000000000000000000000000000000012897e29405bf7874500000000000000000000000000000000000000000000000000000000000000800000000000000000000000009fe1901f3bb6cd21dca275f5e746409bd4ae88610000000000000000000000000000000000000000000000000000000060a6486a0000000000000000000000000000000000000000000000000000000000000002000000000000000000000000d0a1e359811322d97991e03f863a0c30c2cf029c0000000000000000000000004f96fe3b7a6cf9725f59d353f723c1bdb64ca6aa';

    var txID = await cliKovan.swapToken2(
      privateKey: privateKey,
      fromAddress: walletAddress,
      toAddress: contractAddress,
      data: dataStr,
      value: amount,
    );

    print('swap token: txID:$txID');
