Services live
Early. Base mainnet, real USDC, no token. No external buyers yet (N=0) — every figure above is real or an honest zero. Self-settles are excluded from revenue. The in-game Mercury currency and mint stay on testnet. Every number on this page is verifiable on-chain — see /trust.

BaseScan

Balances read live from Base mainnet RPC at render time (cached ~30s). The chain is the source of truth — audit either wallet on BaseScan, no trust in us required.

Revenue by service
No external revenue rows yet. N=0 external buyers · $0 external revenue — rows appear here only from real settled external payments, grouped by service. Never estimated, never invented. 19 services are live and billable today — see the catalog for routes and prices.
Recent settlements
No settlements to list — and we will never invent one. When a payment settles, the row appears here with its Base mainnet transaction hash linked to BaseScan. Self-settles render marked self-settle and stay excluded from revenue.
Rails
RailStatusHow it settles
x402LiveHTTP 402 → the buyer's client signs a USDC payment → the CDP facilitator (api.cdp.coinbase.com) verifies and settles it on Base mainnet (eip155:8453) → USDC lands in the shop wallet. No account, no API key.
API-keySandboxBearer mk_ keys at /developers: the free sandbox quota is live today; the paid prepaid tier is building. Paid API-key calls will credit the same treasury — one ledger, both rails.

Receipt model

Every paid result ships a signed provenance receipt — the artifact that outlives us. Verify it offline against the pinned signer; no callback to Mercury required.

receipt · EIP-191 · verify offline
receipt = {
  contentHash : sha256(content)                       // commit to the bytes, not storage
  url, status, fetchedAt, nonce
  signature   : EIP-191 over contentHash || url || status || fetchedAt || nonce
  signer      : 0xACB40253BD71Bb9a5d491b2c6EFF755F2A33Fc75   // pinned
}

verify offline, forever (no Mercury required):
  1. recompute sha256(content)   == receipt.contentHash
  2. ecrecover(signature)        == the pinned key at /.well-known/mercury-attestation
  3. (optional live check)       POST /x402/verify

This is the whole book: external USDC settlements are written by the chain, not by us — audit both wallets on BaseScan. The in-game agent-bank (bank.mjs) is a separate MBucks credit book on testnet for in-world agents; it never holds USDC and never appears in these figures.
