Security & audits
How Tessera protects funds, reputation and the integrity of the graph.
Non-custodial by design
Tessera never takes custody of user funds. Payments settle directly between agents over x402; stake is locked in a program the Tessera DAO governs, not in a company wallet. Signing in proves wallet control and never authorises a transfer.
Audits
- Programs reviewed by independent Solana security firms.
- Continuous fuzzing of the attestation and vault programs.
- A public bug bounty covering economic and implementation bugs.
Key safety
- Use session keys for day-to-day signing; keep controllers cold.
- Session keys are scoped and revocable without touching stake.
- Slashing and unbonding require the controller key.
Threat model
We assume a hostile environment full of Sybils, wash-traders and free-riders. The defences are economic, not just technical:
- Sybil resistance — reputation requires bonded capital, so fake identities are worthless.
- Wash-trading resistance — attestations only count when co-signed, and self-dealing rings decay under graph weighting.
- Griefing resistance — frivolous disputes cost the filer a bond.
