What it does

BLOB's self-hooked pool charges every trade a 15% ETH treasury tax during launch, then a permanent 5% fee that is burned on the BLOB side or shared with holders as ETH on the ETH side, plus a permanent 0.20% platform fee, while LPs can withdraw freely.

How it works step by step

  • The hook is also the BLOB token itself, and its pool pairs native ETH with BLOB, with launch liquidity seeded single-sided and permanently locked by the hook.
  • During the launch phase every trade pays a 15% tax in ETH that goes straight to an immutable treasury address.
  • After the admin ends the launch tax (a one-way switch), every trade pays a 5% fee instead. Fees taken in BLOB are burned, and fees taken in ETH are split 70% to qualifying holders as claimable ETH and 30% to an eat bounty pool.
  • A permanent 0.20% platform fee in native ETH is charged on every trade and held in a separate fee vault.
  • Holder balances take part in a forced on-chain game: idle balances decay about 1% per day, and random volume-triggered 'eats' can burn up to 25% of a holder's peak balance. Launch caps also limit buys to 0.25% of supply per transfer and 2% per wallet.
Swap behaviour
Each swap pays a 15% ETH launch tax while the launch phase is on, or a 5% game fee once it is off, plus a permanent 0.20% native platform fee. The fee is taken from the ETH input in beforeSwap or from the unspecified side in afterSwap. While the anti-snipe caps are on, buys over 0.25% of supply, or buys that push a wallet above 2%, revert; sells are not capped.
Liquidity behaviour
No liquidity callbacks are enabled, so LPs can add and withdraw freely. The hook's own launch liquidity is permanently locked by design.
Fee behaviour
The launch phase charges a 15% tax, paid to the treasury in ETH. After it ends, a permanent 5% fee applies: BLOB-side fees are 100% burned, and ETH-side fees go 70% to holders and 30% to the bounty pool. A permanent 0.20% native platform fee is added in both phases.
Owner & admin controls
An immutable capAdmin can only switch off, permanently and one way, the 0.25% max-tx cap, the 2% max-wallet cap, and the 15% starting tax (which turns on the 5% game fee). The deployer could add exclusions and link the NFT/renderer once before launch; fee rates and the treasury are hard-coded.

Enabled Uniswap v4 callbacks

afterInitialize, beforeSwap, afterSwap, beforeSwapReturnDelta, afterSwapReturnDelta

afterInitialize: deployer-only launch setup and recording of the locked liquidity range; beforeSwap: takes the ETH tax and platform fee from the ETH input when ETH is the specified side; afterSwap: takes the fee on the unspecified side, routes it, and triggers eats; beforeSwapReturnDelta/afterSwapReturnDelta: let the hook deduct those fees from swap amounts.

Security & trust assessment

Risk level: medium (verified source, medium confidence).

Who controls it: capAdmin holds only three one-way switches. The worst it can do is keep the 15% launch tax and buy caps in place indefinitely; it cannot move funds, mint tokens, or pause trading.

Risk to user funds: Traders pay 15.2% per trade during the launch phase and 5.2% afterwards. Holders' balances are subject to decay and eat burns. Third-party LP withdrawals are never blocked.

Security findings

  • [medium] 15% launch tax with no deadline: Trades pay a 15% tax to the treasury until capAdmin calls removeStartingTax. There is no timer, so the tax can stay on indefinitely.
  • [medium] Holder balances burned by game mechanics: Non-excluded holders' tokens decay about 1% per day and can be partly burned by random eats, capped at 25% of peak per the floor rule. This is code-defined and not admin-controlled.
  • [low] Launch buy and wallet caps: Buys are limited to 0.25% of supply per transfer and 2% per wallet until capAdmin removes each cap one way. Sells are never restricted.
  • [info] Platform controller source truncated: Fee amounts are computed by an immutable controller whose source was not included. The fee figures above come from the hook's constants and comments.
