musig.partial_sig_agg

musig.partial_sig_agg "txid" input_index ["partial_sig",...] Aggregate MuSig2 partial signatures to create adaptor pre-signature s'. Arguments: 1. txid (string, required) Transaction ID 2. input_index (numeric, required) Input index 3. partial_sigs (json array, required) Array of partial signatures from all co-signers [ "partial_sig", (string, required) Partial signature (32-byte hex) ... ] Result: { (json object) "adaptor_presig" : "hex" (string) Aggregated adaptor pre-signature s' (32 bytes) } Examples: > bitcoin-cli musig.partial_sig_agg "txid" 0 '["partial1", "partial2"]'

Signature

musig.partial_sig_agg(txid: string, input_index: number, partial_sigs: array) → any
