Every launch should come with a return ticket.
With Second Chance you buy with a small premium and pick a window from 1 hour to 7 days. If you change your mind during that window, you get back 100% of what you paid for the tokens. If the price rises, you keep them.

The idea
Buying into a launch should not be a leap without a net.
Usually, if you buy and the price drops the next day, the loss is yours. Second Chance splits the decision in two: you buy now and decide later whether to keep. That option has a price — the premium — paid up front.
Regular buy
You pay, receive tokens, and risk starts immediately. If it drops, you sell at a loss.
Limit order
You wait for a price, but you do not hold the tokens until it fills — and it may never fill.
Second Chance
Tokens are set aside in your name at today's price. Until the window ends you can reclaim the full ETH or take the tokens.
How it works
Three steps, one decision.

STEP 1 · OPEN
You choose how many tokens and how long
You pay the token cost plus the premium. The cost is held in the contract and the tokens are reserved for you. You receive a ticket as an NFT.

STEP 2 · WAIT
The window runs, the market moves
Tokens stay reserved and your ETH stays intact. You can sell or gift the ticket in the meantime — whoever holds it decides.

Seen from above: a single path splitting into two arrows. One arrow makes a U-turn back toward a large coin (the refund), the other continues forward toward a stack of tokens (keeping them).
STEP 3 · DECIDE
Reclaim or keep
RECLAIMBefore the window ends: the full cost comes back. The premium is not refunded.
KEEPWhenever you want: tokens move to your wallet. If the window ends and you did nothing, same outcome.
Your ticket is an NFT (ERC-721, symbol 2ND). The refund right can be transferred or sold on any NFT marketplace. The refund or the tokens always go to whoever holds the ticket at that moment.

What does your second chance cost?
Move the price and see when reclaiming beats keeping. The premium uses the same formula as the contract.
Reclaim
You reclaim 0.5 ETH and only lose the premium.

Second Chance
Regular buy in the pool (1% fee)
Approximate. Does not include price impact, the vault surcharge for pending demand, or gas. The vault price starts from the pool price at the beginning of the block.
Transparency
Where every ETH goes.
The vault holds your cost separately and does not touch it until you decide. Only ETH that can no longer be refunded leaves for the market.
The cost
It waits in the vault. If you reclaim, it returns in full to whoever holds the ticket. If you keep the tokens, it is used to buy tokens back in the pool.
The premium
It is not refunded. It buys tokens in the pool to refill the vault inventory — the vault is the one underwriting your option.
The pool 1%
Every Uniswap swap pays 1% to the liquidity position, which belongs to the developer. Vault buybacks pay it too.

Cutaway view of a bank vault with two compartments: the left one holds ETH coins behind a padlock (escrow), the right one holds stacks of tokens with paper reservation tags; a pipe leads out of the vault into a calm pool of liquid on the right (the market). Isometric, wide composition.

Liquidity
Liquidity belongs to the developer. Your refund does not depend on it.
The Uniswap v4 pool is created by the developer and the position NFT stays in their wallet. No Second Chance contract holds or manages liquidity.
- The developer earns 1% of every pool swap.
- The developer can withdraw liquidity. If they do, the vault stops selling new positions.
- Open positions remain 100% refundable: the ETH is in the vault, not the pool.
- Tokens already in your wallet do not have that protection.
Guarantees and risks
What the code promises — and what it does not.
Guaranteed by the contract
- Full cost refundWhile the window has not expired, you receive exactly the ETH that sat in escrow.
- Exact token deliveryYour position's tokens are reserved from the start. No one else can buy them.
- Only the holder decidesOnly whoever holds the ticket can reclaim. After expiry, anyone can trigger delivery, but tokens always go to the holder.
- Price protected within the blockThe vault uses the block-start price if it is higher than spot. Dumping the price right before buying does not make it cheaper.
- Capped buybacksA sandwich only makes the vault buy less. Leftover ETH is bought back later.
What you should know
- The premium does not come backIt is the price of the option. Reclaiming returns the cost, never the premium.
- No external audit yetThere are 18 tests, including fuzz and invariants, but that does not replace an audit.
- The developer controls pool liquidityThey can withdraw it. Open positions are protected; tokens in circulation are not.
- The window expiresAfter expiry you can no longer reclaim. Tokens arrive in your wallet.
- Limited inventoryThe vault starts with 300M tokens. If it runs out, it will not open new positions until buybacks refill it.
- The vault charges a surchargeThe more open positions, the higher the vault price. Splitting a large buy into many smaller ones does not get you a better deal.
FAQ
Before you buy.
What happens if I do nothing when the window ends?
You keep the tokens. After expiry anyone can trigger delivery, and tokens go to the wallet that holds the ticket. ETH can no longer be reclaimed.
Can I reclaim only part of a position?
No. Each position is reclaimed or kept in full. For flexibility, open several smaller positions with different windows.
Why is the vault a bit more expensive than the pool?
Two reasons. The vault takes the higher of the block-start and spot prices so nobody can manipulate it. It also adds a surcharge for open positions — demand the pool does not yet reflect. In return you do not pay the pool's 1% fee when buying.
Can I buy without Second Chance?
Yes. The ETH/2ND Uniswap v4 pool works like any other: buy and sell instantly, with a 1% fee.
What if the developer withdraws liquidity?
Open positions are unaffected: escrow ETH and reserved tokens are in the vault. What does happen is the vault stops opening new positions while liquidity is below half of the initial amount.
Can I sell my refund right?
Yes. The ticket is a standard NFT. If you transfer it, the new holder is who can reclaim the ETH or receive the tokens.
Who keeps the premium?
No one in particular: the vault uses it to buy tokens in the pool and refill inventory. Those buybacks pay the pool's 1% fee, which goes to the developer's position.
