How bound works.

What BOUND is

BOUND is a launchpad for tokens that come tied up with their rules. A creator picks up to five rules when launching, like a cap on how much one wallet can hold or how much anyone can sell at once. The rules live inside the token's own transfer function and inside the BOUND hook on its Uniswap pool, so they check every trade on the BOUND curve and the official Uniswap pool.

Once a token launches, its rules are fixed. There is no owner and no function that changes them, not for the creator, and not for BOUND.

Launching

  1. Pick a name, ticker and picture on the launch page.
  2. Tie on up to five rules and set their limits. The page shows what they would refuse in an example market before anything goes on-chain.
  3. Optionally make the first buy in the same transaction. Your own rules apply to you too.
  4. Sign with your own wallet. BOUND never holds your keys.

Every token has a supply of 1,000,000,000. All of it starts on the bonding curve: 793.1M for sale, 206.9M reserved for the Uniswap pool at graduation.

The curve

Each token trades on its own bonding curve, a constant-product curve with virtual reserves: the price rises as people buy and falls as they sell. Anyone can buy or sell on the curve at any time (subject to the token's rules). The curve always holds exactly the ETH it owes; buying and selling straight back never makes a profit.

Graduation

When the last sale token is sold, the token graduates in the same transaction: the curve opens the token's Uniswap v4 pool (ETH / token, 1% fee tier) at the curve's final price and deposits all the ETH it raised plus the 206.9M reserved tokens as one full-range position.

That position belongs to the curve contract, which has no way to withdraw it, so the liquidity is locked forever. Anyone can call collectLpFees to sweep its trading fees: the ETH is split like curve fees, the tokens are burned.

Before graduation, nobody but the curve can open the pool or add liquidity to it. The BOUND hook enforces this, so graduation can't be blocked or front-run.

Fees

Every trade on a BOUND curve pays 1%, in ETH:

  • 85% to the BOUND treasury, for buyback and burn.
  • 15% to the token's creator, claimable any time from the token page.

After graduation, the Uniswap pool's 1% fee goes to the locked liquidity, and sweeps of it are split the same way. Some rules add their own fees while a token is on the curve: Tithe (to an address the creator picks), Buyer rewards (to holders) and the Sniper tax (burned).

Every rule

Up to five per token. Each one is a check the token runs on itself; the settings below are the limits the contracts accept.

Safety limits

The contracts refuse any rule settings that could trap holders. Whatever a creator picks, any holder can always eventually sell at least 0.05% of supply at a time: sell caps never go below 0.05%, cooldowns are at most a day, vesting fully unlocks within a year, markets open at least four hours a day, and fee rules are capped (tithe 5%, holder rewards 10%, sniper tax 50% and gone within two hours).

The one deliberate exception is P2P-only, a gift token that nobody can sell on a market by design. The launch page and token page say so plainly.

What the rules cover after graduation

Creators choose at launch whether rules stay on after graduation or end there. If they stay:

  • Size and timing rules (max per buy and sell, trade guard, sliding caps, market hours, reactive caps, P2P-only and Entangled locks) are checked on every swap in the official Uniswap pool by the BOUND hook.
  • Wallet rules (max per wallet, cooldown, vesting, allowlist, holder-gated, DEX-only) are checked on every token transfer. Traders who keep balances inside Uniswap instead of their wallet can avoid them there.
  • A transfer into some other contract counts as a wallet-to-wallet send. Turn on DEX-only to refuse those, so every trade has to go through the official markets.

Fee rules (tithe, holder rewards, sniper tax) run only while the token is on the curve.

Contracts

Every contract's source code is published and verified, so anyone can check that the code on-chain is the code described here.

FAQ

Can the creator change the rules later?

No. Rules are fixed at launch. Nobody can change them.

Can BOUND change my token?

No. The factory's owner can only change settings for future launches (curve size, treasury address, pausing new launches). Launched tokens, their curves and their pools can't be touched.

Why was my trade refused?

One of the token's rules said no. BOUND checks your trade before your wallet opens and tells you which rule and why, so you never pay gas for a trade that would fail.

Where do I trade a graduated token?

On its token page here, or any app that routes to Uniswap v4 on Robinhood Chain. The rules still check every trade.

Is BOUND audited?

The contracts have been through adversarial security reviews with every finding fixed and tested, and their source is verified, but there has been no paid third-party audit. Rules limit how a token moves; they don't make it a safe investment.
