Clanker

pumperp launches tokens through Clanker SDK v4 on Base — replacing Fission's Pump.fun integration entirely.

Fee pipeline

sequenceDiagram
  participant T as Clanker token
  participant L as ClankerLocker v4
  participant FL as FeeLocker
  participant P as Protocol wallet

  Note over T: Trading generates LP fees
  P->>L: collectRewards(token)
  L->>FL: Accrue USDC for recipients
  P->>FL: claim(protocol, USDC)
  FL->>P: USDC transfer

Key addresses

Configured in backend/src/config.ts (override via env):

Never hardcode addresses in docs without checking config.ts — use env for deployments.

Deploy

launchToken uses:

• Clanker from clanker-sdk/v4
• FEE_CONFIGS / dynamic fee tier
• getTickFromMarketCapUSDC for initial pool tick
• Protocol + creator recipients in rewards config

Claims

claimPooledFees(tokens[]):

1. For each token: collectRewards on locker
2. Read availableFees(protocol, USDC)
3. claim if above dust threshold
4. Return { txHash, usdcClaimed, perToken }

Batch size limited by CLAIM_BATCH_SIZE to keep gas predictable.

vs Pump.fun (Fission)

Deploy auth

Deploy is fully onchain: clanker-sdk/v4 + protocol wallet via viem. There is no Clanker REST API key in the live launch path.

Optional: PINATA_JWT to pin image URLs to IPFS before deploy (backend/src/services/ipfs.ts).
