Tie the rules.
Every swap pulls through them.

spool is a launchpad and AMM on Solana. Every pool carries its own Knots and pulls every swap through them: anti-snipe, drag fee, exit clock, holder pot, Biggest Catch, arb recapture, LP rewards and more. You tie them at launch, for up to eight pools at once. Once a pool opens they stay tied, and anyone can read them.

01Knots · One swap

A swap pulls the line.Every knot gets a say.

  1. 01Anti-Snipe

    For a window after launch, buys pay a tax that decays to nothing, and each slot has a buy cap. Sells never pay it.

  2. 02Drag Fee

    The fee grows with how hard the swap pulls the price from its recent reference. Pulling it back costs nothing extra.

  3. 03Auto Burn

    A fixed share of the tokens the buy receives is burned in the same transaction.

  4. 04LP Rewards

    An extra fee on buys, kept by the LPs whose liquidity filled it.

  5. 05The money map

    Every fee lands somewhere you can read: the LPs, the creator, the burn and spool, at rates tied when the pool opened.

Thread your own.

Pick knots and they slide onto the line in the order a swap meets them. Each one does a single job with bounded settings, tied when the pool opens.

Rules you can watch.Every one runs on chain.

Four of spool's knots, drawn as they run. These are illustrations, not live data; each knot's parameters and limits are in the docs.

Sheet 02.1Illustration

Multi-pool launch

One token opens in up to eight pools in a single transaction, each against its own quote, with its own liquidity, fee and knots. If any pool fails a check, the whole launch fails.

Sheet 02.2Illustration

Biggest Catch

Rounds align to UTC. The biggest single buy of the round holds the trophy until a bigger one lands. At the close it takes a prize from a pot that arb recapture fills, and part of the rest streams to LPs.

Sheet 02.3Illustration

Arb Recapture

When a pool drifts from its reference price, the swap that closes the gap pays most of the profit back instead of handing it to outside bots: a share to the trader whose swap opened the gap, the Catch pot, spool and the pool's LPs.

Sheet 02.4Illustration

Exit Clock

Each sell pays a rate set by how long the seller held, from the top rate down to the floor over the horizon. Quick flips pay; nobody is locked in.

All knots Open the builder
03Fee lines

Turn a fee right into a token.Its stakers share the income.

Lock a pool's fee right and mint a fee line against it. Every swap in that pool then pays the line's stakers, pro rata.

  1. 01
    Lock a fee right, mint a token

    A pool's fee right is locked behind a fixed-supply token. No owner, no second mint.

  2. 02
    Every swap pays stakers

    Income is released over a set period, up to 14 days, to everyone who stakes the token, and can be claimed whenever they like.

  3. 03
    Its own market at mint

    The token can open with a pool of its own, so holders can trade their share of the line.

  4. 04
    Drops

    Send more of an income token to the fee line and every staker gets their part.

  5. 05
    Terms that end

    Run it for good, or for a term. When a term ends, the fee right reels back to its owner.

05What a launch gets

One transaction.Every knot tied in it.

A launch creates the token, opens its pools and ties their knots in a single transaction. Every choice is shown once more before you sign.

01
Multi-pool launch

One token opens in up to eight pools, one per quote asset, each with its own knots.

Up to 8 pools · One transaction
02
Dev buy lock

Buy your own token inside the launch. The pools' liquidity stays locked for the term you set, while fees stay collectable.

Bought at launch · Liquidity locked
03
LP lock boost

LPs who lock their position for longer earn a larger share of the pool's rewards.

Longer lock · Larger weight
04
Saved lines

Save a set of knots as a named line. Your pools, or anyone's you allow, can run it.

Saved on chain · Reusable
05
Fee split

The base LP fee goes to liquidity providers. Knot fees split between LPs, the creator and spool at rates tied when the pool opens.

Tied at open · Readable on chain

07Read before you trade

Read the knotsbefore you trade.

A pool's knots live on chain from the moment it opens. Scan reads them, with the token's authorities and extensions, before you sign anything.

The knots and their settings

Tied when the pool opened. Nobody can retie them, the creator included.

The token's authorities

Mint and freeze authority, and any Token-2022 extension such as a transfer fee or a transfer hook.

The deposit cap

A per-pool limit the admin can set or clear. Scan shows the pool's value.

Who earns what

The fee split, read from the pool's own account.

The mint address

A token is its address, never its ticker. Check the whole thing.

Who is asking

spool has no airdrop and never asks for a seed phrase or a signature to "verify" a wallet.

09FAQ

Questions,answered plainly.

What is spool?

A launchpad on Solana where every pool pulls each swap through its own Knots. You pick knots such as anti-snipe, drag fees, auto burn and LP rewards, set their parameters and open the pool. The settings are tied when it opens, and every knot can be read before you trade.

Which knots can a pool run?

Anti-Snipe taxes and caps early buys during the launch guard. Drag Fee rises with how hard a swap pulls the price. Auto Burn burns a share of each buy. LP Rewards adds a fee on buys for the LPs that filled them. Others include Wallet Cap, Launch Window, Sandwich Guard, Storm Fee, Exit Clock, Creator Cut, Holder Pot, Biggest Catch and Arb Recapture. The docs list every knot with its parameters and limits.

How many knots fit on one line?

Eight, with at most four guards before the swap. A buy can never pay more than 35% in total, Auto Burn and LP Rewards together stay under 10%, and sell-side knots under 20%. The builder checks all of it as you go.

How does the dev buy lock work?

A creator can buy their own token inside the launch transaction. The pools' liquidity then stays locked for the term the creator sets, while the fees stay collectable. Both are shown on the token's page.

What does spool charge?

Nothing from the base LP fee: that goes to liquidity providers in full. spool takes a share of knot fees, between 20% and 50%, tied when the pool opens and shown on the pool's page.

Can I add knots to a token that already trades?

Yes. You can open spool pools for an existing SPL or Token-2022 token, each with its own knots. spool takes no authority over the token, and its pools elsewhere keep running as they are. Anti-Snipe stays off, since the token already trades.

Does spool support Token-2022?

Yes. Scan shows the extensions a token carries, such as a transfer fee or a transfer hook, before you trade. A transfer fee is a knot outside the pool, and Scan says so.

Can I use the math in my own app?

Yes. lib/spool.js is one file with the catalog, the bounds, the quote and the money map. Import it straight from this site. It signs nothing and asks for no keys.

Is there a $SPOOL token?

Yes, on Solana. Its only contract address is announced here first. Any other token calling itself $SPOOL is not spool's.

How do I know a token or link is real?

A token is its mint address, never its ticker or logo. Check the full address on this page and in Scan. spool has no airdrop and never asks for a seed phrase.
