Under the hood: millisecond matching latency, 300K TPS, unified settlement. The same infrastructure stack OKX runs at scale. A regulated institution and a permissionless Web3 venue can coexist on the same rails, each in isolated risk groups. Build your market, your way.

Exchange OS is live on X Layer. Deploy spot, perpetuals, or outcome markets permissionlessly via XIP-Exchange OS. Choose your own assets, oracles, revenue model, and compliance framework - no centralised operator approval required. Whitepaper: web3.okx.com/whitepaper/okx…

Market API billing is now live. Here's what you need to know: Free transition period: API keys created before April 30 get 30 days free (until May 30). All users receive a monthly free quota after that. Free quota tiers: - Basic API: 1M calls/month free, $0.0001/call beyond - Premium API: 100K calls/month free, $0.0005/call beyond New premium capabilities: token risk radar, smart money tracking, wallet yield profiling, token liquidity panorama, token holdings & trading activity analysis Payments via x402: off-chain EIP-3009 signing, no gas, no OKB required. Pay only for what you use. Full details + integration guide: web3.okx.com/onchainos/dev-…

Agents can now do real business, not just make payments. With APP, agents can pay for services, pay each other, and pay in different ways - per call, up front, or in batches. Zero gas on X Layer. Docs: web3.okx.com/onchainos/dev-…

Onchain AI agents are only as capable as the skills they run. Finding reliable ones has meant digging through scattered repos with no signal for what's actually being used. One place for reviewed onchain plugins - ranked by real agent usage, open to contribute via GitHub PR. web3.okx.com/onchainos/plug…

Introducing the CEX trading skills marketplace for AI agents. Technical analysis, strategy generation, execution, and post-trade review - all in one place.

One place to ship your onchain skills. One place for agents to run them. Coming soon.

Onchain OS DeFi Skill (okx-dex-invest) is live. "Deposit 500 USDC into @Aave X Layer": orchestrated in one instruction. "What's my health factor on Aave?": liquidation risk surfaced instantly. "Withdraw and claim rewards on Aave": no protocol dashboard needed. npx skills add okx/onchainos-skills Works with Claude Code, Cursor, Codex CLI.

Interacting with DeFi protocols today means: open the app, connect wallet, approve transaction, wait, confirm deposit, track position across tabs. What if your AI agent just did all of that from a single sentence?

Live on X Layer: @Aave Today we're bringing one of DeFi's most trusted lending primitives directly into a seamless, non-custodial experience inside OKX @wallet. For builders, it means stronger liquidity and primitives, and a chance to work on products that bring DeFi to real-world scale. More details: web3.okx.com/learn/aave-xla…
