The agentic economy has its next-gen payment layer built on @SuiNetwork. @0xbeepit, a programmable payments platform for autonomous AI agents, is launching out of stealth and naming @SuiNetwork as its exclusive blockchain settlement layer. Explanatory thread below and how this fits nicely into the x402/a402 narrative. - - - - - 1. Intro Beep is building the financial stack where AI agents transact autonomously → paying for APIs, settling microtransactions, and coordinating value without human input. Think: programmable payments for machines. • Stablecoin-native (USDC at launch) • Built for high-frequency agent workflows • Designed for low-latency, predictable execution Team is launching native Sui support given its ability to optimize for machine-speed activity (parallel execution, low-latency finality, composability) 2. Why this matters AI agents can think and act → but they still can’t pay. Current settlement layers aren’t built for bot-to-bot financial coordination. Beep + Sui enables: • Millisecond-speed stablecoin transfers • Zero-fee microtransactions • Deterministic execution for autonomous systems • Global, programmable settlement 3. Live products Two products go live alongside the Sui integration. a. Payment APIs → for apps, services, and autonomous agents needing programmable stablecoin flows. b. Beep Retail ( → a yield product where autonomous agents: • scan opportunities • score risk • allocate capital • auto-compound yield 4. x402 vs a402 Most devs know x402, the early conceptual standard for agent payments. Beep introduces a402 on Sui which is the production-grade, implemented version: • x402 → narrative + concept, with flows picking up • a402 → live protocol powering stablecoin-native agent payments. a402 is built for: → high-frequency AI transactions → stablecoin settlement (USDC first) → zero-fee microtransactions → machine-speed coordination via Sui Where x402 was primarily live on Base, a402 is the Beep’s take on enabling native infrastructure on Sui. 5. Closing Thoughts x402 cumulative transaction volume has been rising steadily, with a sharp pickup starting late October proving that agent-driven payments aren’t theoretical anymore Use cases beyond the usual are still quite niche in nature, with data on senders and recipients still scarce Nonetheless, financial rails for agents is still needed to enable a world where AI shifts beyond just “thinking” to “transacting”. - - - - - Stay tuned for a more detailed report on x402 and payment flows on @mementoresearch.
