Proof Launch

The proving grounds for meme coins on Solana. A pre-launch commitment layer on top of Pump.fun — communities form before a token exists. A meme can only launch once all its backer slots are claimed, and when they fill, the meme's shared pool wallet executes ONE atomic createV2 + buy on Pump.fun. Every backer enters at the identical price. Dev holds zero.

How it works

1. Submit. A creator submits a meme and sets 2–8 backer slots, each with a minimum SOL contribution. Submission costs 0.02 SOL (non-refundable, anti-spam tax). The platform provisions two keypairs per meme: a pool wallet (collects backers' SOL) and a sub-escrow wallet (becomes the coin's on-chain coin_creator, isolates the coin's future trading fees).

2. Back. Backers claim slots first-come, first-served. Each backing transfers SOL directly into the meme's pool wallet on-chain. Backers can withdraw at any time during the backing phase (2% fee).

3. Launch. When all slots fill, the creator clicks Launch. The pool wallet executes a single atomic createV2 + buy transaction on Pump.fun:

   • The token is created in the same block as the dev buy → zero sniper gap.
   • The buy spends the entire pool balance → every backer enters at the same price.
   • The creator (sub-escrow) holds no tokens directly → dev allocation is 0%.
   • Every Proof Launch coin's contract address ends in …pooL so anyone can verify on-chain that it's a real Proof launch.

4. Distribute. Each backer's proportional share of the pool's tokens is automatically sent to their wallet in the same request as the launch. No claim button required.

Refund protection

Two automatic safety nets ensure backer SOL is never permanently stuck:

• 3-day backing deadline. If slots don't fill within the creator's chosen window, every backer is automatically refunded 100% (no fee).
• 24-hour launch window. Once funded, the creator has 24 hours to launch. If they don't, every backer is automatically refunded 100% (no fee). Closes the abandonment hole where a creator could leave backers waiting indefinitely.

Both refund paths run on the same hourly cron via the proven refundMemePool function — no support tickets, no human in the loop.

Trading fees

Pump.fun routes a share of every trade on a launched token back to the on-chain coin_creator PDA. Because each Proof meme has its own per-coin sub-escrow as coin_creator, fees isolate exactly per coin and are independently verifiable on-chain.

Hourly, a cron job:

1. Calls collect_creator_fee on each coin's vault → drains to that coin's sub-escrow.
2. Sweeps the sub-escrow → shared platform escrow.
3. Splits 90% to backers (proportional to backing size) / 10% to the platform.
4. Credits each backer's claimable_fees_sol in the database.

Backers claim their share with one click (per-meme or aggregate "Claim All") — payout is a single SOL transfer from escrow to the backer's wallet.

Security

Backer funds are non-custodial in the sense that they sit in a per-meme pool wallet (one wallet per meme, not a global pot) until the meme either launches or refunds. Pool wallets are controlled by the platform; their behavior is constrained to exactly two actions: launch (atomic createV2+buy on Pump.fun) or refund (return SOL to original backers). No third action is possible from the API surface.

See SECURITY.md for responsible disclosure and audit status.

⚠️ Not formally audited by a third-party firm. Meme coins are highly speculative. Don't back more than you can afford to lose.
