WatchTower

Free nonce monitoring and multisig monitoring for Solana. Detect durable nonce staging, signer-compromise, and governance-manipulation patterns before funds move.

Free on-chain monitoring for durable nonce staging and multisig configuration changes on Solana. Get alerted to signer-compromise and governance-manipulation patterns before funds move. Major Solana attacks often start before execution — through compromised signers, multisig changes, or nonce setup. These actions can look normal on-chain by themselves. In the right context, they can signal an attack in progress. This free tool monitors those early signals so teams can investigate before damage is done. Monitoring for new durable nonce account creation that could indicate transaction pre-staging for future unauthorized execution. Detection of authority transfers on existing nonce accounts that may signal compromised signers or governance manipulation attempts. Tracking configuration modifications to Squads v4 multisig programs including member additions, removals, and threshold changes. Protocols with significant TVL or upgrade authority controlled by multisigs Governance systems that use Squads v4 for operational security Teams that need visibility into nonce activity across their programs Security teams performing ongoing monitoring as part of post-deployment operations Proactive After-Deployment Monitoring: Lessons From an Auditor → Announcing sec3 WatchTower: Smart Monitor for Smart Contracts → Sec3 provides audits, formal verification, and continuous security support for Solana protocols.
