PayAI Network

Robinhood's L2 blockchain built on Arbitrum Orbit for tokenized real-world assets — the settlement layer behind its EU stock tokens. Announced June 2025; a competing approach to Solana-native tokenized stocks (Token-2022 / Securitize).

Open-source control plane that turns any API (OpenAPI or recovered docs) into first-call-correct agent tools over MCP. Keys stay in the OS keychain and are injected only at call time, host-pinned. Composes with x402; Superteam Brasil / Dev3Pack. Product: geckovision.tech.
