Cross-chain creator fee scanner, claimer, and paid intelligence API for 12 DeFi launchpads on Solana, Base, Ethereum, and BNB Chain
ClaimScan is a free tool that scans and claims unclaimed creator fees across 12 DeFi launchpads on Solana, Base, Ethereum, and BNB Chain.
Around 40% of creator fees go unclaimed. Creators launch tokens, generate volume, earn fees, and never collect them. ClaimScan finds that money and lets you claim it.

V1.5 is the update where ClaimScan went from read-only scanner to full claimer. Bags.fm is the first platform with direct on-chain claiming built in. No third-party custody, no approvals, no token permissions. Connect your wallet, review the simulation, sign, done.
How the claim flow works:
- ClaimScan detects unclaimed fees on Bags.fm for your wallet
- A claim transaction is built server-side with optimized compute units
- The transaction is simulated before it ever reaches your wallet
- You review and sign in your own wallet (Phantom, Backpack, Ledger, or any Wallet Standard compatible wallet)
- ClaimScan tracks the transaction from submission through on-chain finalization
- Claim status updates in real time:
pending → signing → submitted → confirmed → finalized
Claim architecture:
- Zero-custody: Your keys never leave your wallet. Transactions are constructed server-side but signed exclusively client-side
- Pre-sign simulation: Every transaction is simulated on-chain before the wallet prompt appears, so failed claims are caught before you spend gas
- Priority fees: Dynamic compute unit pricing calibrated per transaction for reliable confirmation, even during network congestion
- Turnstile-gated: Every claim request is verified through Cloudflare Turnstile to prevent bot abuse and replay attacks
- Finalization tracking: Claims are tracked end-to-end with immutable state transitions. Once finalized, a claim cannot be reverted or replayed
- Cryptographic verification: Claim requests are signed and verified at every step, from client to server to chain
- Hardware wallet support: Full compatibility with Ledger and other hardware signers
- Auto-discovery: Wallet detection via Wallet Standard protocol. No manual wallet imports needed
More platforms coming in V3. Bags.fm is just the start.
ClaimScan V2 introduces a paid API powered by the x402 protocol. Any developer, bot, or AI agent can query ClaimScan data and pay per request in USDC. No API keys, no subscriptions, no accounts. Just pay and receive.
Endpoints:
| Endpoint | Price | What you get |
|---|---|---|
GET /api/v2/fees?wallet=<address> |
$0.01 | Full fee report across all 12 platforms and 4 chains |
GET /api/v2/export?wallet=<address> |
$0.05 | CSV or JSON export of all fee records |
GET /api/v2/intelligence?wallet=<address> |
$0.02 | Intelligence report: ClaimScan fees + Allium cross-chain enrichment |
GET /api/v2/resolve?ows_wallet=<name> |
$0.01 | Resolve an OWS wallet name into multi-chain addresses |
How it works:
- An agent or developer makes a request to any paid endpoint
- ClaimScan responds with HTTP 402 (Payment Required)
- The client signs a USDC payment on Base Mainnet automatically
- ClaimScan verifies the payment via facilitator and returns the data
All endpoints are discoverable through the x402 bazaar extension. An AI agent can find ClaimScan, read the input/output schema, pay, and consume the data without any human setup.
Built into the protocol layer:
- Bazaar discovery: Every paid endpoint publishes its schema so AI agents can find and use it autonomously
- Idempotency: Payment-identifier extension prevents duplicate charges when clients retry
- Payment observability: Every verify, settle, and failure event is logged with structured tracing and forwarded to Sentry
Compatible with OWS (Open Wallet Standard) for seamless agent access:
ows pay request "https://claimscan.tech/api/v2/intelligence?wallet=0x..." --wallet my-agentPowered by:
- x402 for trustless per-request payments in USDC on Base Mainnet
- Allium for cross-chain transaction history, PnL, and portfolio context
- OWS for multi-chain wallet identity and agent-friendly authentication
- Defense in depth: Multiple layers of abuse prevention across all endpoints
- Bot protection: Turnstile verification on sensitive operations
- Request signing: All client-server communication cryptographically signed
- Zero-custody claiming: Transactions signed exclusively in user wallets
- Tamper-proof claims: Claim states are immutable once finalized
- On-chain verifiable: Every fee record independently verifiable on-chain
- Anti-enumeration: Rate-limited identity resolution prevents scraping
- Honeypot endpoints: Fake data traps to detect and fingerprint scrapers
- CSV injection protection: All export values sanitized against formula injection before reaching spreadsheets
- Fast scans: All routes optimized for parallel execution across 4 chains
- Smart caching: Multi-layer caching (Redis + DB) keeps data fresh without hammering the chain
- Background indexing: Automated token discovery via Helius DAS webhooks
- Graceful degradation: Partial results instead of timeouts
- SSE streaming: Real-time scan progress and live fee updates via Server-Sent Events
