This paper introduces a series of methodologies for Bitcoin recovery, facilitated by the Rarimo protocol. While existing smart contract platforms are capable of verifying Rarimo's execution proofs, extending this methodology to networks that do not possess cost-effective SNARK verification presents ongoing challenges. We propose the RBR protocol, which facilitates recovery through a trustless escrow mechanism and demonstrates its interoperability with current Bitcoin recovery solutions.
