Stablecoins + AI Agents + x402 = the future of autonomous internet money.

2/ SDK for Agents The (@)uaid/agent-sdk in 60 seconds: The problem: AI agents need to pay for API calls, inference, tools, but there's no payment standard. You end up writing 50+ lines of Solana token transfer code per integration. The fix: 3 lines. Every payment writes a JSON memo on-chain via Solana's Memo Program: taskId, serviceType, nonce (timestamp), agent pubkey. The provider verifies the tx signature, parses the memo, checks the nonce hasn't expired (replay protection), and stores the signature to prevent reuse. Framework integrations: LangChain, createPaidTool() wraps any tool with auto-payment. CrewAI: same pattern, JSON input parsing Vercel AI SDK: drop-in payment tool Generic, createPaymentMiddleware() wraps any async function BalanceManager handles the rest: waitForBalance() polls until funded, onLowBalance() fires a callback when you're running low. Headless. No browser wallet. Just a private key and an RPC. Built for servers and agents, not humans.

Introductie van de Universal AI Dollar (@uaidvaleo) dApp, een volledige walkthrough. $UAID is onze crypto-gecollateraliseerde stablecoin, speciaal ontworpen voor betalingen aan AI-agenten op @solana. Wat je ziet: → Dashboard met live protocolstatistieken → Minten van UAID met SOL-collateral (150%+ ratio) → 1:1 USDC↔UAID swap via de Peg Stability Module → Agent SDK met pay-per-call voor @LangChain, CrewAI & @vercel AI Mensen minten het. Agenten besteden het. Alles wordt in milliseconden op Solana geregeld. Live op devnet (intern testen). SDK op npm. 🧵 Diepgaande analyses hieronder ↓
