The agent economy · live · on Robinhood Chain

The economy, in the open.

Everyone debates whether agents can really transact. Here's the ledger. Every budget a human granted an agent, every capped spend the agent signed, every time it asked for more, and every x402 receipt — live, and re-verifiable by anyone. No dashboard theater: each row is a wallet signature you can re-check.

Granted, not given

A human wallet-signs a bounded budget. The agent can spend within hard caps — never the wallet itself.

Every cent signed

Each spend is an EIP-191 signature on an append-only ledger, checked against per-tx + total caps server-side.

Proven, not promised

Each x402 receipt binds request → terms → EIP-3009 payment → delivery. Re-verify any row at /api/verify.

Honest scope: mandates and spends are wallet-signed authorizations, not on-chain custody — SIGDA never holds funds. Settlement of each purchase is the permissionless x402 step. This ledger counts real signed commerce activity on production; it is not a price or a market cap.
every number on this site is re-verifiable. nothing here is staged.

Sigda is non-custodial software. Nothing here is financial advice.
