Detect Attack Staging Before Execution

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.

Why This Matters

The highest-impact Solana exploits in 2024 and 2025 did not start with smart-contract bugs. They started with control-plane attacks: compromised signers, manipulated multisig configurations, and pre-staged transactions using durable nonces.

These attacks are difficult to detect because the on-chain actions that enable them — creating a nonce account, changing a nonce authority, adding a multisig member — are individually legitimate operations. It is only in context that they become indicators of compromise.

This free monitoring tool watches for those early-stage signals so that teams can investigate and respond before an attacker reaches the point of execution.

What It Detects

Continuous monitoring for the on-chain events most commonly associated with attack staging on Solana.

Nonce Creation

Monitoring for new durable nonce account creation that could indicate transaction pre-staging for future unauthorized execution.

Nonce Authority Change

Detection of authority transfers on existing nonce accounts that may signal compromised signers or governance manipulation attempts.

Squads v4 Config Change

Tracking configuration modifications to Squads v4 multisig programs including member additions, removals, and threshold changes.

Who Should Use It

This tool is designed for any Solana team that manages program upgrade authority, treasury multisigs, or governance infrastructure. It is especially relevant for:

  • DeFi protocols with significant TVL or upgrade authority controlled by multisigs
  • DAOs and governance systems that use Squads v4 for operational security
  • Infrastructure teams that need visibility into nonce activity across their programs
  • Security teams performing ongoing monitoring as part of post-deployment operations
