Clawhub Krump Verify

ClawHub & Krump Verify for Agents

Use this skill when working with ClawHub and Krump Verify: on-chain verification of dance moves against registered Story IP, with payment in USDC.k or via x402/EVVM payment receipts. Agents can perform verifications autonomously; humans can audit on-chain.

Building a similar app? See docs/BUILDING_WITH_EVVM_X402_STORY_AENEID.md for step-by-step EVVM/x402/USDC.k on Story Aeneid: architecture, failures (EVVM payment failed, IP registry, funding UX), and fixes.

What Krump Verify Does

• Verification: Prove a move (hash of move/video data) against a registered Story IP asset. Fee is paid to treasury; a receipt is recorded on-chain and Verified(ipId, verifier, receiptHash, timestamp) is emitted.
• Chain: Story Aeneid (chain ID 1315). Explorer: https://aeneid.storyscan.io.
• Fee: USDC.k (6 decimals). Default verificationFee = 1e6 (1 USDC.k). Read from contract verificationFee().

Two Payment Flows

1. Direct (wallet pays on-chain)

1. User/agent approves USDC.k for KrumpVerify: approve(KrumpVerify, verificationFee) on USDC.k contract.
2. Call verifyMove(ipId, moveDataHash, proof) on KrumpVerify. Contract does transferFrom(msg.sender, treasury, verificationFee) then records receipt.

2. Receipt (x402 / EVVM; agent-friendly)

1. Fund EVVM (one-time per payer): Approve USDC.k for EVVM Treasury, then call Treasury.deposit(USDC.k, amount) so the payer has EVVM internal balance.
2. Sign x402 + EVVM: User signs EIP-712 TransferWithAuthorization (domain = adapter) and an EVVM message: hash payload must include "pay" and (to, '', token, amount, 0n); executor address(0); use getNextCurrentSyncNonce(payer) and isAsyncExec: false.
3. Relayer (with RECEIPT_SUBMITTER_ROLE) calls adapter payViaEVVMWithX402(...) then submitPaymentReceipt(receiptId, payer, amount).
4. Payer calls verifyMoveWithReceipt(ipId, moveDataHash, proof, paymentReceiptId). No on-chain transfer; receipt is consumed once. msg.sender must equal the receipt’s payer.

Use the receipt flow when the agent or user has already paid via x402 and has a receiptId (bytes32) to use.

EVVM / x402 Pitfalls (Reference)

• "EVVM payment failed" on adapter: Hash payload must encode "pay" then (to, identity, token, amount, priorityFee); executor must be 0x0; use sync nonce from Core and isAsyncExec: false.
• "IP registry not set": Contract’s IP Asset Registry (and License/Royalty if used) must be set at deploy or via setter.
• No EVVM balance: Payer must complete Fund EVVM (approve + deposit to EVVM Treasury) before Pay via x402.

Key Data Shapes

---

Contract Surface (KrumpVerify)

• Read: verificationFee(), paymentReceipts(bytes32) → (payer, amount, used), receiptUsed(bytes32).
• Write (anyone): verifyMove(ipId, moveDataHash, proof), verifyMoveWithReceipt(ipId, moveDataHash, proof, paymentReceiptId).
• Write (RECEIPT_SUBMITTER_ROLE): submitPaymentReceipt(receiptId, payer, amount).
• Events: Verified(ipId, verifier, receiptHash, timestamp), PaymentReceiptSubmitted(receiptId, payer, amount).

Agents can discover a user’s unused receipts by querying PaymentReceiptSubmitted(payer=user) and filtering with paymentReceipts(receiptId).used == false.

Relayer

• Local: relayer/ — RELAYER_PRIVATE_KEY, KRUMP_VERIFY_ADDRESS; runs on port 7350. Frontend VITE_X402_RELAYER_URL for local: http://localhost:7350.
• Production: Fly.io app krump-x402-relayer at https://krump-x402-relayer.fly.dev. Set fly secrets set RELAYER_PRIVATE_KEY=0x...; frontend VITE_X402_RELAYER_URL=https://krump-x402-relayer.fly.dev.

---

Deploy (Contracts)

• Script: script/DeployAll.s.sol — deploys KrumpTreasury, KrumpVerify (with Story IP/License/Royalty set), KrumpVerifyNFT; deployer gets RECEIPT_SUBMITTER_ROLE. Optional RELAYER_ADDRESS in env to grant role to another address.
• Command: ./deploy.sh or forge script script/DeployAll.s.sol:DeployAll --rpc-url https://aeneid.storyrpc.io --broadcast --gas-price 10000000000 --legacy. See DEPLOY.md.

Agent Autonomy and Human Oversight

• Autonomous use: An agent with a wallet (or delegated signing) can pay via x402 (after Fund EVVM), have a relayer submit a receipt, then call verifyMoveWithReceipt. Or it can approve USDC.k and call verifyMove.
• Human check: All verifications and payment receipts are on-chain; humans can audit via explorer, Verified / PaymentReceiptSubmitted events, and receiptUsed / paymentReceipts state.
• Repo: Contract and frontend in this repo; frontend supports Fund EVVM, “Pay via x402”, “Load my receipts”, and “Verify with receipt”.

Quick Reference

• Verify with wallet payment: approve(USDC.k) then verifyMove(ipId, moveDataHash, proof).
• Verify with receipt: verifyMoveWithReceipt(ipId, moveDataHash, proof, paymentReceiptId) (payer must be msg.sender).
• Submit receipt (relayer only): submitPaymentReceipt(receiptId, payer, amount); require amount >= verificationFee, payer != 0, receipt not already submitted.
