  merged_tx
end

#signed_correctly?(*key_pairs) ⇒ Boolean

Checks to ensure that every signature for the envelope is a valid signature of one of the provided ‘key_pairs`

NOTE: this does not do any authorization checks, which requires access to the current ledger state.

Parameters:

  • key_pairs (Array<Stellar::KeyPair>) —

    The key pairs to check the envelopes signatures against

Returns:

  • (Boolean) —

    true if all signatures are from the provided key_pairs and validly sign the tx’s hash
