CreateMuSig2SyntheticXpub()

CExtPubKey CreateMuSig2SyntheticXpub

(

const CPubKey &

pubkey

)

Construct the BIP 328 synthetic xpub for a pubkey.

Here is the call graph for this function:

MuSig2AggregatePubkeys() [2/2]

std::optional< CPubKey > MuSig2AggregatePubkeys	(	const std::vector< CPubKey > &	pubkeys,
		secp256k1_musig_keyagg_cache &	keyagg_cache,
		const std::optional< CPubKey > &	expected_aggregate )

Compute the full aggregate pubkey from the given participant pubkeys in their current order. Outputs the secp256k1_musig_keyagg_cache and validates that the computed aggregate pubkey matches an expected aggregate pubkey. This is necessary for most MuSig2 operations.
