This pull request refactors how fee asset IDs are handled in the Polkadot signing flow, introducing a new FeeAssetId enum to distinguish between native and asset-based transaction fees. It also adds support for using the ChargeAssetTxPayment extension when paying transaction tips with the native chain token, based on a new proto field. These changes improve code clarity and flexibility for fee payments.

Fee asset handling improvements

  • Introduced the FeeAssetId enum to represent either a native token or a specific asset for transaction fees, replacing the previous usage of a raw u32 type. This change affects both the context struct and related functions.
  • Updated the fee_asset_id_from_tw function to return a FeeAssetId instead of a u32, and added logic to support charging native fees as assets when the new proto field is set.

Transaction payment extension logic

  • Modified the logic in PolkadotEntry to use ChargeAssetTxPayment with the correct asset ID type, utilizing the new as_u32() method of FeeAssetId.

Protocol buffer changes

  • Added the charge_native_as_asset_tx_payment boolean field to the SigningInput proto message to control whether native token tips are paid using the asset extension.
