During the buildathon, Permit evolved from a programmable payment concept into a complete authorization infrastructure for constrained payments. We designed and implemented the core policy model, smart contract architecture, payment execution flow, wallet authorization flow, backend API, database architecture, blockchain indexing, payment proof system, and agent payment model. The main focus throughout development has been security and enforceable authorization. Payment limits are enforced on-chain rather than trusted to the frontend or backend, with explicit rejection states and transaction proofs. We also refined the architecture to minimize smart contract surface area and make the system easier to test, audit, and extend for recurring payments, payment links, developer integrations, and autonomous agent payments. Permit is being built specifically for deployment on Arbitrum and demonstrates how programmable payment permissions can be used by both humans and software.
