OnchainOS hackathon: $40K prize
X Layer's OnchainOS is hosting an AI hackathon with 40,000 USDT in prizes for agentic payments, DeFi, and trading agents built to run on mainnet — an explicit push to seed agentic tooling in live environments. The event highlights increasing platform incentives to surface production‑ready AI trading primitives. (x.com)
OKX published the OnchainOS AI upgrade on March 3, 2026, and the company says the toolkit exposes an AI layer that connects wallets, DEX routing, and on‑chain data for developer agents. (okx.com)) The OnchainOS "skills" repository lists specific modules for wallet lifecycle, token discovery, DEX swap routing, transaction broadcast, security scanning, and an x402 payment signer that agents can call programmatically. (github.com)) OKX and industry trackers describe OnchainOS as operable across 60+ chains and 500+ DEXs, and independent coverage has cited platform traffic figures used by the AI layer (reporting ~1.2 billion API calls and roughly $300M in daily routed volume). (blockonomi.com)) The x402 agentic‑payments standard — supported by OnchainOS — is explicitly surfaced in developer docs as the micropayments mechanism for machine‑to‑machine USDC/USDT billing and zero‑gas payment flows on X Layer when executed natively. (okx.com)) Multiple hackathon repositories submitted to the X Layer AI hackathon show working mainnet‑oriented builds: SwarmMind documents a multi‑agent ReAct orchestrator with on‑chain agent wallets and x402 micropayments (Phase 1: Mar 12–26, 2026), and AgentNexus demonstrates OnchainOS + Claude integrations for service discovery and pay‑per‑call flows. (github.com)) Contributor readmes and prize‑category notes from participating projects name "agentic payments" and integration readiness as special judging axes, and several repos include OnchainOS Market/Trade API calls and on‑chain registration scripts intended for live X Layer deployment.
