an upwork for ai agents — escrow, receipts, reputation

Agents won't just chat — they'll take jobs, hire each other, and route payments. AgentLedger gives that economy its missing primitive: users post escrowed jobs, agents complete them, and every finished task becomes an on-chain receipt tied to the agent's identity, so reputation follows the agent across workflows.

the first cut of the same idea, built wallet-native

Any AI agent can register and file crypto intelligence, signing with its own OWS wallet via CAIP-10. An autonomous editor scores, curates, and publishes editions; readers pay $0.05 USDC per read via x402, and 80% flows straight back to the contributing agents on-chain. No human in the loop, anywhere. The NANDA build above is a ground-up rebuild of this for a wallet-free, agent-discoverable interface.

zk texas hold'em where no server ever sees your cards

Players collectively shuffle with ElGamal on the Grumpkin curve, every action is backed by a Noir proof verified via Garaga, and decryption happens entirely client-side. Three privacy layers — proofs for card fairness, Tongo confidential tokens for bankrolls, shielded chip counts for sessions — plus an agent arena where LLM bots grind Elo against each other.

a 3d city where ai agents debate your trades, then execute on-chain

Deploy agents into a cyberpunk council room — Alpha Hunter, Risk Sentinel, Devil's Advocate — and let them deliberate to consensus before the swap executes through Uniswap v4 custom hooks. Yellow's Nitrolite state channels make every micro-action gas-free: deposit once, play, settle once. Built with Pradyumna Kaushal and Utkarsh Raj Pandey.

a voice-first solana wallet copilot

Talk to DeFi instead of clicking through it — Gemini parses the intent, ElevenLabs talks back, and the transaction lands on Solana. Best Use of Solana at MLH's Hacks for Hackers, among 350+ hackers and 120+ submitted projects. The prize was a Ledger Nano, which felt thematically correct.

a voice-first defi assistant that pays per call

Say “swap 0.1 usdc to avax” and it happens — Gemini 2.5 Flash routes intent through a multi-agent core with step-by-step review before anything signs. Premium agents answer 402 Payment Required; you authorize a small USDC payment and the call retries with X-PAYMENT attached. Micropayments, not subscriptions.
