V3.6: In-app claim is live on every Solana launchpad
This is the biggest update to ClaimScan since V2.0.
Before V3.6, only one Solana launchpad supported in-app claim. After V3.6, all six do. Connect your wallet once. Claim from Pump.fun, Bags.fm, Believe, Coinbarrel, Raydium LaunchLab, and RevShare in the same place.
No more visiting six different dApps. No more leaving ClaimScan to collect what you earned.
What's new
6 Solana launchpads now claimable in-app
| Launchpad | What V3.6 ships |
|---|---|
| Pump.fun + PumpSwap | Dual-builder dispatch: one route handles both the bonding curve and the AMM creator-fee withdraws. Both synthetic mint rows clear in a single batch. |
| Bags.fm | Unchanged from V1.5 (still the canonical reference flow). Now part of a unified Claim All experience alongside the five new launchpads. |
| Believe (Meteora DBC) | Atomic dual-claim per pool: one signed transaction sweeps both the quote token (SOL, auto-unwrapped from WSOL) and the base token. |
| Coinbarrel | Atomic dual-claim per pool with auto WSOL unwrap and dual-key fee math. Both display rows (SOL synthetic and token-A) clear after one signature. |
| Raydium LaunchLab | Clean-room hand-rolled claim_creator_fee instruction built from the public Anchor IDL, with a vault balance pre-flight gate that returns 403 before charging gas or burning a claim attempt slot if the vault is below rent-exempt minimum. Hidden when the Fee Key NFT is no longer held. |
| RevShare (SPL Token-2022) | Per-mint WithdrawWithheldTokensFromMint with idempotent ATA creation. Re-verifies the withhold authority at transaction build time. Batch cap raised to 25 mints per claim because RevShare creators commonly hold 20+ mints under a single authority. |
How it feels for the creator
Open the platform tab on your profile, click Claim All, sign once per batch in your wallet, and the SOL lands. Two seconds of work for a year of accumulated fees.
Pre-flight gates catch the dead-end cases (empty vault, wrong authority, ATA missing) before your wallet ever sees the transaction. No wasted gas. No mystery failures.
How to claim
- Go to claimscan.tech
- Paste your wallet address, Twitter handle, or ENS name
- Open the tab for the launchpad you want to claim from
- Click Claim All
- Review the cost preview (network fees + ATA rent for new accounts + service fee breakdown)
- Sign in your wallet (Phantom, Backpack, Solflare, Ledger, anything Wallet Standard compatible)
- The fees land directly in your wallet
Service fee is a flat 0.85% deducted on-chain from the claimed amount. No subscription, no monthly cost, no hidden math.
Architecture highlights
- Zero-custody by design. ClaimScan generates the unsigned transaction server-side. Your wallet signs locally. The broadcast goes directly to the Solana network. ClaimScan never sees your private key.
- One canonical security flow, six platform implementations. Every claim route mirrors the same 13 security gates (Content-Type validation, HMAC fail-fast, wallet validation, mint array bounds, Cloudflare Turnstile, wallet proof, stale-claim cleanup, rate limit, atomic insert, batched transaction wrap, per-mint fee math, dual confirmation tokens, error-shape parity).
- Clean-room instruction builds where there is no public SDK. Raydium LaunchLab and Pump.fun + PumpSwap have no GPL-friendly SDK. Their claim instructions are reconstructed from the public on-chain Anchor IDL with locked discriminators and audited account signer flags.
- Atomic dual-claim where the AMM splits fees across two tokens. Believe and Coinbarrel both emit two rows per pool (quote + base). One signed transaction clears both rows via a single SDK or program call.
- Pre-flight gates on every risky route. Raydium checks the creator vault balance before insert. RevShare re-reads the withhold authority byte offset at transaction build time. The cost preview endpoint reads the same RPC state the POST route uses, so the price you see is the price you sign.
- Per-platform batch caps. RevShare allows 25 mints per batch (token-2022 creators run deep). Everything else caps at 10 to keep transactions under the 1232-byte Solana limit.
- Per-mint Sentry breadcrumbs. Every claim emits
claim.initiated,claim.success, orclaim.failurewith the platform and mint metadata so success rate, failure taxonomy, and unharvested-remainder telemetry are all observable end-to-end.
What was tested
- Unit tests across all six builders
- Component tests for every platform tab (gate composition, CTA gating, dual-seed overlay behavior)
- Integration tests against real fixture wallets (env-gated, opt-in)
- Compile-fence tests ensuring every Platform enum entry has an explicit capability flag
- Cross-phase route diff artifacts confirming all six routes preserve the canonical 13-gate flow
What's next
V4 is in-app EVM claims: Clanker, Zora, Bankr, Flaunch, Flap, and Klik unified behind a single wallet adapter that handles Solana and EVM signing in one modal. RevShare token-account-level fee harvesting (for the long-tail of unharvested balances stuck in individual token accounts) ships alongside.
