How Nodule works.

Each token trades in one Uniswap v4 pool against its pair: ETH, USDC, another major crypto token or a tokenized stock from Ondo. A hook on that pool watches every trade. Buying is free of tax. Selling at a profit pays a share of that profit, and the share goes to the holders once per season, on Tax Day.

The hook remembers what you paid for your tokens, in the pair. When you sell, it compares what the sale is worth with what those tokens cost you.

• Buying is never taxed.
• Selling at a loss is never taxed.
• Selling at a profit pays the rate times the profit. Sell part of your bag and the matching part of your cost is used.

The rate starts at the creator’s start rate and falls in a straight line to the floor over the decay time. After that it stays at the floor.

rate = start - (start - floor) x held / decay      while held < decay
rate = floor                                       after that
tax  = rate x (sale value - cost of the tokens sold)

The example used across this site is a token that starts at 25%, falls to 1% and takes 7 days to get there.

Your rate depends on how long you have held, counted from the average date of your purchases. One wallet has one clock per token.

• Buy more and the clock blends: the new date sits between the old one and now, weighted by size.
• Tokens older than the decay time count as exactly that old. A small old bag cannot make a large new purchase look old.
• Sell part of your bag and the clock does not move.

A token runs in seasons. The creator picks the length, from 3 to 14 days, and the first season starts at launch.

1. 1Someone sells at a profit and pays tax.
2. 2The tax is credited at once to the holders, split by reward weight, and locked.
3. 3The season ends. That is Tax Day.
4. 4What you earned unlocks. You take it in the pair with claim.

Claims do not expire. What you leave unclaimed stays yours and adds up across seasons.

Your share of each tax payment follows your weight. Weight is the amount you bought times a multiplier that grows from 1x to 3x over the decay time.

weight = tokens bought x (1 + 2 x min(1, held / decay))

• Two holders with the same bag: the one who held past the decay time earns three times what a buyer from today earns.
• Tokens that reached you by transfer have no weight.
• The multiplier is refreshed when your wallet is touched: a buy, a sale, a claim, or anyone calling poke for you. Between touches it stays at the last value, never above the real one.

A sale of any size gives up what you earned in the current season and leaves you without weight until the next one. What you give up is split among the holders who stayed.

In the next season your weight comes back the first time your wallet is touched: a buy, a sale, a claim or a poke.

Rewards from earlier seasons that already unlocked are not affected. Only the season in progress is given up.

A creator can switch on a rebate for people who sell below their cost. When it is on, one fifth of every tax payment goes to the season’s rebate fund instead of the holders.

• A loss on tokens you bought is recorded for the season when you sell, for the wallet that signs the sale.
• On Tax Day the fund pays min(fund, total losses x rebate rate), shared in proportion to each loss. You take yours with claimRebate.
• Whatever the fund does not pay goes back to the holders over time.
• With the rebate off, all of the tax goes to holders.

The rebate rate can be at most one fifth of the floor rate, and never above 10%. A token with a 1% floor can offer 0.2%. To offer 1%, the floor has to be 5%. The cap exists because a larger rebate would let an old wallet with a lot of weight fake a loss through a second wallet and come out ahead.

The token is built to be bought and sold in its pool. Moving it between wallets works, with consequences.

• Tokens you receive by transfer pay the start rate on their full sale value, for good, and earn no rewards. Buy in the pool to start your own clock.
• Tokens you send away take the matching share of this season’s rewards with them. That share is lost.
• Tokens sent to a contract stay there. A staking pool, a locker, a bridge, a vesting contract, a multisig, an escrow or an exchange deposit contract can receive them and can never pay them out. From a contract they can only be sold in the pool or burned.

Do not deposit a Nodule token anywhere. Keep it in the wallet that bought it.

At the first trade of each block the hook notes the pool price, which is where the previous block closed. If someone bought earlier in the same block and pushed the price up, a sale in that block is split in two.

• Up to what the sale would be worth from the previous close: the normal rule, with your own rate.
• Anything above that: the start rate, whatever your holding time or cost.

You never receive less than you would have by selling first, from the previous close. Wait one block after a large buy and the normal rule applies to the whole sale.

Sells that ask for an exact amount of the pair out are refused. Sell an exact amount of tokens instead.

The fading rate is for the wallet that signs the transaction and delivers its own tokens. Anything else is treated as a new holder.

• A regular wallet selling its own tokens gets its own rate.
• Smart contract wallets and relayed sales always pay the start rate. Through a router that pulls the tokens with a separate contract, they pay it on the full sale value.
• Some routes settle in two steps. The hook first holds back the start rate on the sale value, then works out the real tax when the tokens arrive in the same transaction and sends the difference back in the pair. If that payment cannot be delivered, it waits for you in withdrawRefund.

Quote tools and token scanners that only look at the swap output may show the start rate as the tax. The refund arrives separately in the same transaction.

One transaction creates the token, opens the pool, deposits the whole supply and locks it. You set five rules and they never change.

• The supply is 1,000,000,000 tokens. All of it goes into the pool as one-sided liquidity. Nobody deposits ETH: it comes from the buyers.
• There is no presale, no team allocation and no mint function.
• The amount you add to the launch becomes your first buy, paid in the pair, in the same transaction and before anyone else. You set a minimum amount of tokens and the launch reverts if the buy would return less.
• You choose the pair and whether the token gets an AI agent. Neither can change after launch.
• Your first buy follows the same rules as every other holder: same tax, same clock, same weight.
• The starting price is set by the protocol, not by the creator.

A token trades against one pair, chosen at launch from a list the protocol keeps. Prices, the tax, rewards, rebates and fees are all counted and paid in that pair.

• The protocol can add a pair or close one to new launches. Tokens that already launched keep their pair.
• Stock pairs are Ondo's tokenized shares. As the issuer, Ondo can pause its tokens or block an address, and trades in those pools follow that.
• WBTC is bitcoin held by BitGo, and SOL is bridged from Solana by Wormhole.
• You can pay with ETH in pools paired with something else, for example ETH into a UNI pool. It takes one transaction through Uniswap and costs more gas. Some stocks have too little Uniswap liquidity for this, so there you pay with the stock itself.

A token can launch with an agent. The creator picks its character, model and powers. From then on the creator share of the pool fee goes to the agent’s treasury instead of the creator.

Posts on X, buybacks

• The limits are written into the treasury at launch. The creator and the agent can't raise them later.
• AI costs come first. Buybacks cannot spend the part of the treasury still set aside for the AI, up to the AI cost cap.
• The agent thinks on Nodule's servers, which hold the key that can act for it. That key can only do what the treasury allows.
• The creator can pause the agent and change its character. They cannot withdraw.
• If the agent does nothing for 30 days, anyone can trigger its buybacks, so the treasury always ends up in the token.
• Posting on X happens off-chain. The creator connects the agent's account after launch.

The pool charges 1% on every trade, in both directions. This is separate from the tax.

The part collected in the pair

The part collected in the token

Burned.

Anyone can call collect for a token. It gathers the pool fees, credits the pair side to the creator and the protocol, and burns the token side. Each of them takes their balance with withdraw.

The creator earns from pool fees only, and nothing at all when the token has an agent. None of the tax goes to the creator.

If almost nobody holds with weight, there is no fair way to split a tax payment. While the total weight is under 0.1% of the supply, tax is set aside instead of being credited.

What is set aside is released over time to whoever has weight at that moment. Each interaction with the token releases elapsed / (season + elapsed) of what is left. One call after a full season releases half. Leftovers from the rebate fund join the same pile.

• A token's tax rules are set at launch and its creator can't change them.
• The launcher holds the liquidity position and has no function to withdraw it.
• The token has a fixed supply, no mint, no owner, no pause and no blacklist.
• The token only trades in its Nodule pool. Any other pool or pair can receive it and can never pay it out, so no market can form around the tax.
• Tokens cannot be flash-borrowed out of the pool.
• The hook and the launcher refuse ETH that does not come from the Uniswap pool manager.

How the design behaves at the edges. Worth reading before you trade.

• Emergency switch. If a token’s tax ever misbehaves, Nodule can switch it off so trading never stops.
• The tax works per block. It is enforced inside each transaction and each block. Someone splitting sells across many wallets and blocks can pay somewhat less than the rules intend.
• Timing matters. Selling in the same block as a buy that moved the price pays the start rate on the uplift.
• Keep tokens in your wallet. A token sent to a contract stays there.
• Smart wallets always pay the start rate.
• Third-party tools may show the start rate as the tax, depending on how they simulate a sale. This page and the trade panel show the real one.
• The last holder collects. If everyone else sold, the last wallet with weight receives the parked tax as time passes.
• Gas. The hook does bookkeeping on every trade. Through Uniswap’s Universal Router, expect about 310k gas for a buy or a sale. A transfer costs about 205k, a claim about 190k and a launch about 2.2M.
• Agents think on Nodule’s servers. Their treasuries live on chain: the creator can’t withdraw from them, and if an agent goes quiet for 30 days, anyone can trigger its buybacks.
• Stock pairs use Ondo’s tokenized shares. As the issuer, Ondo can pause its tokens or block an address.
• Tokens are made by their creators, not by Nodule, and can lose all of their value.
