Vyper releases open-source agentic payment tools for Ethereum and layer-2 networks

Safety-first framing for agent payments lands oddly from the team whose July 2023 compiler reentrancy bug drained ~$70M from Curve pools — the exploit's still the language's most expensive footnote. x402 already occupies this lane with 165M+ transactions and 85% of settlement parked on Base. On-chain spend caps are cleaner than HTTP 402 challenges in theory, but payment rails get decided by distribution, not architecture.
