Secret Recovery Service

SRS - Secure Recovery Service

SRS is a secure, multi-party retrieval service that simplifies non-custodial crypto wallets. It eliminates the need for remembering lengthy recovery phrases by using convenient 4-word mnemonics. Unlike HD wallets, SRS allows an arbitrary set of secrets to be stored and recovered with one short phrase. It supports use cases for both long-term vaulting of secrets and daily joint-custodial wallet transaction signing. Supported by a Protocol Labs research grant.

InfoSec

Security Audits

Blockchain Security Research

Our team has made significant contributions to blockchain security through vulnerability research and responsible disclosure, including identifying critical AMM vulnerabilities in prominent DeFi protocols. We provide professional security audit services for Algorand protocols, having audited Tinyman's Governance System and Liquid Staking System. To ensure the highest security standards, we regularly commission and implement third-party security audits on our own systems, demonstrating our commitment to ecosystem stability.
