Descriptor Wallet Policies

dev.descriptor-wallet-policies

Descriptor wallet policies define a wallet as a descriptor template plus key information items, making account structure portable across software and hardware signers. They standardize how external signers can register, verify, and later derive the same wallet without relying on custom wallet-specific side data.
