- isDescriptor(): checks if string is tr(...) format - normalizeToDescriptor(): wraps hex pubkey as tr(pubkey) - extractPubKey(): extracts pubkey from simple descriptor - parseHDDescriptor(): parses HD descriptor components Enables backwards compatibility for legacy hex pubkeys.
Interface for signing with output descriptors, abstracting HD vs static key implementations.
Wraps existing Identity implementations to provide DescriptorProvider interface with static tr(pubkey) descriptors.
- Change DefaultContractParams to use string descriptors instead of Uint8Array - Add normalizeToDescriptor() for backwards compatibility with hex pubkeys - Update serializeParams/deserializeParams for descriptor format - Update test helpers to use valid secp256k1 public keys - All existing tests pass with the new format
- Add walletDescriptor field to PathContext (preferred over walletPubKey) - Mark walletPubKey as @deprecated with migration note - Update resolveRole to use walletDescriptor with fallback to walletPubKey - Handle descriptor-to-pubkey extraction for role matching
