Overview

Sigil Bitcoin is a workspace of Bitcoin libraries for Sigil.

The packages are layered so applications can import only the pieces they need:

• `(sigil bitcoin primitives)` provides HASH160, HASH256, tagged hashes, and Taproot tag constants.
• `(sigil bitcoin encoding)` provides hex, Base58Check, Bech32, Bech32m, and SegWit address codecs.
• `(sigil secp256k1)` provides native libsecp256k1 bytevector bindings, including public-key point operations and x-only Taproot key tweaks.
• `(sigil bitcoin keys)` provides WIF, addresses, BIP32 extended keys, and BIP39 mnemonics.
• `(sigil bitcoin script)` provides script byte constructors and standard scriptPubKey templates.
• `(sigil bitcoin tx)` provides transaction structs, wire serialization, txids, P2PKH/P2WPKH/P2WSH single-key/P2TR signing, and PSBT v0 parsing, metadata preservation, input/output annotation, signing, and finalization helpers.
• `(sigil bitcoin miniscript)` provides Miniscript fragments, type metadata, hash-lock and branch combinators, descriptor parsing with checksums, BIP389 multipath key derivation, Taproot script-tree hashing and output-key compilation, concrete BIP327 `musig(...)` key aggregation for Taproot descriptor scriptPubKeys, BIP388 wallet policy expansion, PSBT planning records with WSH script material, and descriptor-plan PSBT signing wrappers.

The generated API reference is built from the same JSON files produced by `sigil build`.
