Implementation of the types and their (de-)serialisation via SCALE codec. On the Rust side, the codec types and primitive types are implemented via the parity-codec.

Changelog

12.0.1 June 24, 2024

Important Changes:

• Addition of an optional signedTransaction field to the SignerResult response for injected signers. This only applies to the signPayload method exposed in the Signer interface for polkadot-js. As the name suggests the field expects a signed transaction (extrinsic) when inputted. When its present, the api will not add the signature to the payload, but instead broadcast the inputted signed transaction. This means the signer may modify the payload it's given. The only part of the payload that may not be modified is the call data. This is verified on the api, and will throw an error if it does not match the initial payloads call data.
  • This is very useful for signers that want to adjust the mode and metadataHash field for the CheckMetadataHash signed extension.
  • Note that this is not your traditional breaking change since it more-so acts as an addition, but since this is a high magnitude change it is going to be considered a MAJOR bump.

• Replace system_accountNextIndex with runtime api call accountNonceApi for api.derive.tx.signingInfo
