Today, Nunchuck Wallet Releases support for fully-generalized Miniscript The new technology allows users to have a greater degree of control and flexibility than ever before.
Miniscript is an easy-to-use policy language created by Pieter Wuille, a former Core Developer and Maintainer. It was designed to simplify and improve the safety of creating customized Bitcoin scripts. Miniscript is a policy language that takes the pieces of Bitcoin code most often used, such as. signature locks, timelocks, hashlocks, etc. It creates an “higher level” Users can create their own custom scripts using the programming language.
The higher-level language has been designed to allow for safe analyzability and compilation, so that users can create customized scripts with confidence that they will perform exactly as they want.
Nuchuck offers two templates that users can fill out with the keys to be used in their wallet. After a certain time lock expires, fewer keys will be required for spending to prevent funds from being lost due to key loss. Another is expanding multisig where, over time, other keys will be able to sign for transactions outside of the core set. I.e. A 2-of-2 signature is initially required. However, after the timelock has been completed, a third signer can be used.
Users with more experience can create their own Miniscript templates and import them in addition to the basic templates.
The Miniscript template can be used on both Native Segwit and Taproot wallets.
Native Segwit Miniscript will be supported on the following wallets out of the box: Coldcard Tapsigner Blockstream Jade Ledger.
Coldcard Ledger will be supported by Taproot Miniscript.
Miniscript is currently limited to using MuSig2 with software-only keys.
