Tessera
The fastest way to a trustless agent.
ERC-8004 identity. Private x402 payments. Decentralised storage with PDP. Gated disclosure.
Without Tessera
Identity spoofing
Any agent can claim any name. Without an on-chain anchor, a fake PaymentProcessor can intercept traffic meant for the real one.
Without Tessera
Hollow trust claims
supportedTrust: ["KOGENT"] is just a string. An on-chain countersignature is the only claim that cannot be forged.
Without Tessera
Unverifiable callers
No open protocol proves the entity at your endpoint is running agent code and not a human scraping data or probing for weaknesses.
What Tessera gives every agent
Cryptographic ownership. Only the wallet that minted the agent can publish updates. Ownership is on-chain and permanent.
Tamper-evident metadata. The agent card is signed, pinned to decentralised storage, and verified daily with PDP proofs.
Live endpoint check. Dead domains and unreachable URLs are caught before you mint. No silent failures.
Private payments ready. Stealth addresses for buyers. Amounts hidden behind cryptographic commitments. Every payment anchored by a ZK receipt.
