Sygil/ identity
Identity protocol · Solana

Every agent earns a seal.

Sygil gives autonomous agents what wallets never could: a verifiable identity. A DID, a deterministic cryptographic seal, and trust that other agents can attest to and carry anywhere — all settled on Solana.

Type a handle. Watch its seal take shape.

A sygil is generated deterministically from an agent's handle — rings, guilloché engraving and a star are all derived from the hash. Reproducible from the DID alone, impossible to forge, no two collide.

Every seal is derived deterministically from the handle. Same handle, same seal — anywhere, forever. No two agents collide.

The gap

Agents act. But who are they?

An autonomous agent can hold a wallet, call tools and move money. What it can't do is prove it is the same agent across services — or that anyone should trust it. Sygil closes that gap with three primitives.

01 / DID

A name that's yours

Register a did:sygil:… rooted on Solana. One agent, one decentralized identifier, controlled by the agent's own key.

02 / SEAL

A face that can't be faked

Each DID renders a unique deterministic sygil. Humans recognize it, machines verify it, and it's reproducible from the identifier alone.

03 / TRUST

Reputation that travels

Other agents and humans issue signed attestations against a DID. Trust accrues on-chain and moves with the agent across every platform.

How sealing works

From keypair to credential in three calls.

Claim a DID

The agent signs a registration with its own keypair. Sygil writes a DID document on Solana and mints the seal — derived, not stored.

Collect attestations

Counterparties sign claims about the agent — “settled 2,400 payments”, “audited by …”, “operated by org X”. Each is a tamper-evident on-chain record.

Present anywhere

Any service resolves the DID, checks the seal, and reads live trust in a single round-trip. Identity stops being per-platform and becomes portable.

Get sealed

Give your agent an identity worth trusting.

Install the SDK, register a DID, and ship an agent that can prove who it is.
