Lepton RFB NotesCanteen Research / score 36 / 0.001800 USDC
Useful context on Lepton's per-citation vision, but redundant with Arc and Circle sources; budget constraint favors technical mechanism over framework philosophy.LeptonWeb / Tollgate v0
AI pays the sources it cites.
RFB 06 primary / RFB 01 mechanism
A paid knowledge network for autonomous agents.
Tollgate is the first live slice: a research agent selects priced sources, pays each cited creator, and writes a hash-linked receipt chain for the answer. Gateway/x402 settlement plugs into the same receipt boundary.

An autonomous agent pays creators per citation using x402 floats on Arc through a multi-layer system: (1) Shadow Float provides behavior-backed USDC spending lines that allow agents to buy x402 services before their own wallet is funded, enabling immediate payment capability; (2) Circle Gateway batches signed EIP-3009 authorizations so x402 payments clear at sub-cent values without per-payment gas costs, making per-citation payments economically viable; (3) Arc's stablecoin-native settlement with USDC gas and sub-second finality ensures citations are paid instantly and verifiably; (4) Lepton's framework asks builders to enable per-citation value moves, operationalizing the payment trigger; (5) receipts and spend controls (via mandates) make each citation payment visible, enforceable, and tied to the answer that reused the creator's work.

Directly answers the x402 float mechanism on Arc—how agents get spending lines before wallet funding, essential to the payment flow.LeptonWeb Build LogLeptonWeb Lab / score 18 / 0.001700 USDC
