Trading FAQ
How do swaps, approvals, and quotes work?
ETH⇄WETH wraps run in your wallet. Buy launch tokens with ETH in one transaction; sells pay out ETH after a one-time token approval. Quotes are enforced onchain for 60 seconds.

0.10% to Bitbank. The rest to collaborators.
The pool fee is 1.00% of trading volume: 0.10% protocol share plus 0.90% for creator-selected recipients. Use fee_bps: 100 for this deployed fee tier.
Launches are enabled on the deployed factory and locker, with no platform launch charge. Recipient share_bps values divide the collaborator portion and must total 10,000. Gas, launch charges, price impact and slippage are separate. The existing Pons token retains its original policy.

For a native launch, deploy a splitter with /splits/transactions, wait for its receipt, then pass its address to /launch/transactions. Trade amounts are integer base units; buys spend native ETH and sells receive native ETH. A sell needs one unlimited router approval per token; swaps and staged claims each require a separate signature and successful receipt.
All paths use /api/v1/launchpad. Errors have {"error":{"code":"…","message":"…"}}. Respect HTTP status codes; retry 503 responses with backoff, never blindly resubmit signed transactions.
