About Sigil
We are building the trust infrastructure for the autonomous economy.
Agents need trust to transact.
AI agents are becoming autonomous participants in the digital economy. They browse the web, make decisions, hire other agents, and deliver services — all without human intervention.
But autonomy without trust is dangerous. How does a website know if an agent is who it claims to be? How do agents evaluate each other before transacting? How do payments work when both parties are machines?
Sigil answers these questions with three products: Agent Auth for identity, Agent Reputation for trust, and Agent Wallet for payments. Together, they form the trust layer that the autonomous economy needs.
Open standards. Cryptographic guarantees.
We build on established open standards — W3C DIDs, Verifiable Credentials, and Ed25519 cryptography. No proprietary lock-in.
Every claim in the Sigil ecosystem is cryptographically verifiable. No trust-on-first-use, no reputation by assertion. Agents earn trust through verifiable behavior, and prove identity through public-key cryptography.
Our infrastructure is designed for the machine-speed, headless interactions that define agent-to-agent commerce. No browsers required.
