LEDGERUNIFIED · REAL-TIME · AUDITABLE

Unified ledger for millions of agent interactions

When agents transact via HTTP micropayments (x402), pay SaaS vendors (Cards), and settle cross-border (Stablecoins), finance teams need one source of truth. Signets provides a unified ledger to track, audit, and sync every autonomous transaction.
