getUnsignedSerialized method

Uint8List getUnsignedSerialized({ int? chainId = 1, })

The transaction pre-image.

The hash of this is the digest which needs to be signed to authorize this transaction.

Implementation

Uint8List getUnsignedSerialized({int? chainId = 1}) {
  if (isEIP1559 && chainId != null) {
    if (isCeloTx) {
      final encodedTx = LengthTrackingByteSink();

      encodedTx.addByte(0x7b);// 👈 Celo type 123

      encodedTx.add(
        rlp.encode(
          _encodeCeloType123ToRlp(
            this,
            null,
            BigInt.from(chainId),
          ),
        ),
      );

      encodedTx.close();
      return encodedTx.asBytes();
    } else {
      final encodedTx = LengthTrackingByteSink();
      encodedTx.addByte(0x02);
      encodedTx.add(
        rlp.encode(_encodeEIP1559ToRlp(this, null, BigInt.from(chainId))),
      );

      encodedTx.close();

      return encodedTx.asBytes();
    }
  }

  final innerSignature = chainId == null
      ? null
      : MsgSignature(BigInt.zero, BigInt.zero, chainId);

  return uint8ListFromList(rlp.encode(_encodeToRlp(this, innerSignature)));
}
