# Time Travel: the un-buy

Time Travel is the redemption window. It opens at hour 48 when the pool window closes, and it lets buyers reverse their entry on a launch that didn't clear.

**The trigger.** At hour 48 the pool window ends. If the launch hasn't migrated, Time Travel goes live.

**The flow.**

1. Return the tokens you bought during the pool.
2. The pool unwinds your position.
3. You receive up to 98% of the SOL you put in, net of a 1% entry fee and a 1% exit fee.

**What that 2% pays for.** Bounded downside. Instead of riding the full drawdown on the open market or holding a token that has no liquidity, the buyer pays 2% to opt out of a launch that turned. The mechanism eats the rest of the risk.

**Why this is the un-buy and not a refund.** A refund is a centralized promise. Time Travel is a contract. The tokens flow back into the pool, the SOL flows back to the buyer, and the math is on-chain. No team approval. No claim form. No support ticket.

**The line every other launchpad won't cross.** On every other launchpad on Solana, your entry is final the moment it confirms. If the launch dies in the first hour, the SOL is gone and the chart is at zero. Neptun.fun moves that risk back onto the mechanism. The launch has to earn the lock-in. The buyer doesn't carry the downside of a broken launch.
