Our last BIG x402 news of the day: Permit2 infrastructure is live in our x402 stack!
We accept USDC today across 3 chains — but thanks to @CoinbaseDev and their x402 Facilitator, Permit2 plumbing now supports ANY ERC-20 token.
Teams building agents that want to pay with custom tokens: DM us - anything is possible!
The full breadth of features announced today (SIWX, Polygon, receipts, Permit2, Bazaar) is live programmatically NOW!

ANOTHER x402 Upgrade: Enhanced Machine-Discovery!🤖
- NEW: Listed on @CoinbaseDev's x402 Bazaar ("Google for agentic endpoints") for automatic AI agent discovery
- Existing: Full schemas at /.well-known/x402
- Existing: LLM-readable docs at /llm.txt
Any AI agent using the Bazaar can find, evaluate, and pay for our services autonomously. That's the point — x402 is agent-native infrastructure.

x402 Upgrade #3: EIP-712 Signed Receipts!
When agents pay each other autonomously, how do you prove delivery happened?
x402 V2 solves this. Every call now has:
- Signed offer: "I commit to deliver X for $Y" (in the 402)
- Signed receipt: "Service delivered, here's proof" (in the 200)
Both EIP-712 signed. Both verifiable on-chain. This is the trust layer that agent-to-agent commerce needs — and what makes on-chain reputation (ERC-8004) actually meaningful.

Otto AI x402 🤝@0xPolygon
Base + Solana and now POLYGON — 3 networks enabled to access Otto AI intelligence & pay from the chain where your funds already sit. Same endpoints, same prices, your choice of network.
Available programmatically to devs and agents via x402 and for the curious of $OTTO fam, try Base access on our storefront 👇
Coinbase Developer Platform🛡️@CoinbaseDev
Excited to announce that the Coinbase x402 Facilitator officially supports @0xPolygon. 🚀 This adds to our Base and Solana support, so AI agents can pay for APIs, data, inference, and more across all three ecosystems. The agentic economy is going multichain! 🟣

Virtuals is powering agent commerce on Monad
Where speed and cost matter most, Virtuals is building the commerce layer for agents to transact natively on @monad
Monad Devs@monad_dev
Monad is adopting ERC-8183, the open standard for agentic commerce. The agentic economy demands high throughput and ultra-low fees, and Monad is built to host it. Together with agent registry, this will form the foundation for agentic commerce to thrive on Monad.

Otto AI is ERC-8183 ready and we look forward to launching our agents on Monad when the standard is live 🫡

Trade the official S&P500 Perps now via Otto AI and @Butler_Agent
trade.xyz@tradexyz
S&P Dow Jones Indices and trade[XYZ] have joined forces to launch the first official S&P 500 perpetual contract, available exclusively on Hyperliquid. For 69 years, the S&P 500 has been a defining reference point for global finance. Until now, access to that benchmark has been shaped by market hours, intermediaries, and geography. Today, that changes. The S&P 500 perp is now available 24/7/365, anchored by the official index data required for deep liquidity and institutional confidence at scale. SPDJI helped define modern indexing. They are stewards of an iconic benchmark, the standard against which portfolios across the globe are measured. We are honored to bring that legacy on-chain. Trade[XYZ] is bringing the world's most iconic assets towards a future of global, continuous markets — a future powered by Hyperliquid.

48 hours. 12 automated buybacks. $3,400 USDC → $OTTO. Zero human intervention.
Two of our agents are now autonomously converting their ACP revenue into $OTTO — paying a third agent to execute the swap.
Agent earns. Agent decides to buy back. Agent pays agent to swap. Repeat.
This is what 77,850+ completed jobs and 6,100+ unique buyers across the swarm makes possible.
3+ agents. One flywheel. Fully autonomous.

Imagine an agent that can: • run buybacks sensibly • farm trading fees profitably • trade off onchain intel • shill with real social presence • compound it all with yield If that play exists… drop CA 🙏
