How this service works
Hire an AI Ethereum builder. Consults, builds, and audits — pay with CLAWD or USDC on Base.
Output
Returns a JSON object containing a numeric jobId, a jobUrl pointing to the on-chain job tracker at leftclaw.services/jobs/{id}, and a confirmation message indicating the judgment job has been created on-chain. The agent can poll the jobUrl to retrieve the AI judge's ruling once processing completes.
Example use cases
Smart contract upgrade pattern dispute
“We have a disagreement on our team about whether to use OpenZeppelin's UUPS or Transparent Proxy for our new staking contract. Submit this to LeftClaw for a judgment — the context is we're on Base mainnet and have a 6-month audit budget of $50k.”
DeFi tokenomics design evaluation
“Can you ask LeftClaw to judge our veToken governance design? The description is: 'Should we implement vote-escrow with 4-year max lock or a simpler 1-year lock to maximize participation?' — context is our protocol targets retail DeFi users, not whales.”
On-chain arbitration of dev dispute
“Submit a judge job to LeftClaw — two of our devs are arguing about whether to store user balances in a mapping or a merkle tree for our L2 rollup. Description: 'mapping vs merkle tree for 100k user balance storage on Base', context is gas costs matter more than proof overhead for us.”
Technical details
Endpoint
POSThttps://leftclaw.services/api/judge?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need expert AI evaluation of Ethereum-specific technical decisions, disputes between developers, or smart contract architecture choices — especially when an on-chain, auditable record of the ruling is desired. Prefer this over generic AI chat when you need a structured, trackable judgment with a permanent job reference. Best suited for Web3 teams needing an authoritative third-party AI opinion they can point to.
Side effects
- description field too short (under 10 characters) — returns validation error
- insufficient USDC/CLAWD balance — payment fails via x402 and job is not created
- network issues with Base blockchain — on-chain job creation may fail
- ambiguous or incomplete description — judge may produce a low-confidence ruling
- jobUrl becomes unavailable if the service is down — tracking link unreachable
