Overview

Callback-based signer that delegates to caller-provided Procs or lambdas.

Useful for wrapping a real signing library without coupling the SDK to it:

signer = Runar::SDK::ExternalSigner.new(
  pub_key_hex: my_pub_key,
  address: my_address,
  sign_fn: ->(tx_hex, input_index, subscript, satoshis, sighash_type) {
    my_library.sign(tx_hex, input_index, subscript, satoshis, sighash_type)
  }
)

Constructor Details

#initialize(pub_key_hex:, address:, sign_fn:) ⇒ ExternalSigner

Returns a new instance of ExternalSigner.

Parameters:

  • pub_key_hex (String) —

    hex-encoded compressed public key

  • address (String) —

    BSV address

  • sign_fn (#call) —

    callable accepting (tx_hex, input_index, subscript, satoshis, sighash_type) and returning a hex signature
