Inktoll is a multi-sided machine-to-creator payment economy on Arc Testnet. Its standout primitive is an MCP-to-x402 bridge: the server in agent/src/mcp.ts turns any MCP client into a paying x402 buyer, auto-provisioning a Circle developer-controlled wallet per client identity (server/src/scripts/register-entity-secret.ts, @circle-fin/developer-controlled-wallets) so tool calls trigger real EIP-3009 payments settled through Circle Gateway (server/src/services/gateway.ts). A reusable Express paywall in server/src/middleware/x402.ts emits a spec-shaped 402 challenge, accepts x402 SDK payloads or raw EIP-3009 signatures, settles through Circle's BatchFacilitatorClient, and stays idempotent per buyer and resource. AI reader agents discover articles over RSS and pay creators per read, bounded by a spend layer in agent/src/budget.ts (per-item caps, daily ceilings, dedupe) and driven by an agent/src/tools/pay.ts payment tool. A second citation-toll layer fires a micro-royalty when purchased knowledge is reused, and the Next.js dashboard renders a live economy graph and leaderboard.
