EthereumTransaction.ContractGeneric example

[codeandgraphics]

Hello!

Trying to sign eth contract method call with TrustSDK/WalletCore, then try to sign this data with sdk_sign URL Scheme. TrustWallet responds with the sign_error. Any example of how we can sign a contract call correctly?

    let signerInput = EthereumSigningInput.with {
      $0.toAddress = "0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D"
      $0.chainID = BigInt("1").serialize()!
      $0.nonce = BigInt("477").serialize()!
      $0.gasPrice = BigInt("2112000000").serialize()!
      $0.gasLimit = BigInt("21000").serialize()!
      $0.privateKey = wallet.getKeyForCoin(coin: .ethereum).data
      $0.transaction = EthereumTransaction.with {
        $0.contractGeneric = EthereumTransaction.ContractGeneric.with {
          $0.data = Data(hexString:"ad5c4648")!
          $0.amount = BigInt("0").serialize()!
        }
      }
    }

If we use erc20 transfer – it's all ok, but no success with ContractGeneric.

Try this one

    let signerInput = EthereumSigningInput.with {
      $0.toAddress = "0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D"
      $0.chainID = BigInt("1").serialize()!
      $0.nonce = BigInt("477").serialize()!
      $0.gasPrice = BigInt("2112000000").serialize()!
      $0.gasLimit = BigInt("21000").serialize()!
      $0.privateKey = wallet.getKeyForCoin(coin: .ethereum).data
      $0.transaction = EthereumTransaction.with {
        $0.transactionOneof = EthereumTransaction.ContractGeneric.with {
          $0.data = Data(hexString:"ad5c4648")!
          $0.amount = BigInt("0").serialize()!
        }
      }
    }
