The bdk library aims to be the core building block for Bitcoin wallets of any kind. The bdk-reserves library provides an implementation of proof-of-reserves for bdk.

  • It produces and validates proofs in the form of PSBT's.
  • The implementation was inspired by BIP-0127 and BIP-0322.


The implementation of bdk-reserves was sponsored by AMINA Bank.
