ValidationApi

public protocol ValidationApi : BaseApi

Undocumented

  • This API will take a partially signed transaction and a set of public keys that the owner has the ability to sign for and return the minimal subset of public keys, that should add signatures to the transaction.

    Default Implementation

    Declaration

    Swift

    func getRequiredSignatures(byTransaction trx: Transaction, keys: [Address]) -> Single<[Address]>

    Parameters

    trx

    Partially signed transaction.
    keys

    Available owner public keys.

    Return Value

    Public keys that should add signatures.

  • This method will return the set of all public keys, that could possibly sign for a given transaction. This call can be used by wallets to filter their set of public keys, to just the relevant subset prior to calling get_required_signatures(), to get the minimum subset.

    Default Implementation

    Declaration

    Swift

    func getPotentialSignatures(byTransaction trx: Transaction) -> Single<[Address]>

    Parameters

    trx

    Unsigned transaction.

    Return Value

    Public keys that can sign transaction.
