Options for a software signer
Adjust the behavior of our software signers and the way a transaction is finalized
Fields§
§trust_witness_utxo: bool
Whether the signer should trust the witness_utxo
, if the non_witness_utxo
hasn’t been
provided
Defaults to false
to mitigate the “SegWit bug” which could trick the wallet into
paying a fee larger than expected.
Some wallets, especially if relatively old, might not provide the non_witness_utxo
for
SegWit transactions in the PSBT they generate: in those cases setting this to true
should correctly produce a signature, at the expense of an increased trust in the creator
of the PSBT.

assume_height: Option<u32>
Whether the wallet should assume a specific height has been reached when trying to finalize a transaction
The wallet will only “use” a timelock to satisfy the spending policy of an input if the timelock height has already been reached. This option allows overriding the “current height” to let the wallet use timelocks in the future to spend a coin.
allow_all_sighashes: bool
Whether the signer should use the sighash_type
set in the PSBT when signing, no matter
what its value is
Defaults to false
which will only allow signing using SIGHASH_ALL
.
try_finalize: bool
Whether to try finalizing the PSBT after the inputs are signed.
Defaults to true
which will try finalizing PSBT after inputs are signed.
tap_leaves_options: TapLeavesOptions
Specifies which Taproot script-spend leaves we should sign for. This option is ignored if we’re signing a non-taproot PSBT.
Defaults to All, i.e., the wallet will sign all the leaves it has a key for.
sign_with_tap_internal_key: bool
Whether we should try to sign a taproot transaction with the taproot internal key or not. This option is ignored if we’re signing a non-taproot PSBT.
Defaults to true
, i.e., we always try to sign with the taproot internal key.
allow_grinding: bool
Whether we should grind ECDSA signature to ensure signing with low r
or not.
Defaults to true
, i.e., we always grind ECDSA signature to sign with low r.
