How 8453.trade works

Anti-snipe

For a window after launch, buys share a per-block cap in dollars and pay a snipe tax that goes to the Nth-buy pot, else the last-buyer pot, else the protocol. It applies to every router and bot, since it runs in the pool. Nobody else can add liquidity during the window. Sells are never touched.

Breathing cap

The largest buy allowed follows a sine wave from launch: it starts at the average, rises by the swing a quarter cycle later, falls by the swing three quarters in, and never drops below the floor. All buys of one transaction count together. Sells are never capped.

Dump guard

During the window after launch, and again after the pool opens, one transaction can sell at most a share of the 1B supply. Several sells in one transaction count together. Large holders can still exit, in steps.

Hot potato

Whoever made the last qualifying buy can't sell or send a token until a different wallet makes a qualifying buy, or until the cool-off runs out. Receiving is always fine. Nobody is exempt, the creator included.

Max per wallet

From launch until the window after the pool opens ends, no wallet may end up holding more than the cap, by buying or receiving. Selling and sending are never limited. Protocol contracts are exempt.

MEV shield

During the window, any trade whose transaction pays more than the set priority fee above the base fee reverts. The cap is at least 5 gwei so normal transactions pass.

Momentum

The largest buy allowed rides a damped oscillator. Each buy kicks it: the cap swells, peaks a quarter period later, dips below rest half a period later, and the swing fades. Never below the floor, never above 4x the resting cap.

Sell tax decay

Sells pay an extra pool fee that starts at the set rate after launch and falls in a straight line to zero. It is taken in tokens, which are burned when the pool's fees are collected. A fee, never a refusal.

Sliding caps

Separate caps on every buy and every sell, set for launch and for market-cap levels in US dollars. The level in force is the highest one the market cap has reached, so caps slide back if it drops. 0 means no cap on that side.

Whale guard

During the window after launch, and again after the pool opens, one transaction can buy at most the cap. Splitting a buy into several swaps doesn't get around it. Sells are never limited.

Dynamic fee

The LP fee starts at the pool's base fee and rises toward the ceiling as a swap trades more relative to pool depth. Sensitivity sets how fast it climbs.

Market hours (sells always open)

Buys are accepted only Monday to Friday, 9:30 am to 4 pm New York time, with daylight saving, NYSE holidays and 1 pm early closes computed on-chain. Selling is possible at any time.

Market hours

Buys and sells are accepted only Monday to Friday, 9:30 am to 4 pm New York time, with daylight saving, NYSE holidays and 1 pm early closes computed on-chain. Holders can't sell outside the session.

Ping pong

After a buy only a sell can trade, after a sell only a buy; the first trade must be a buy. Only trades of at least the minimum size flip the turn. If nobody takes the turn before the timeout, both sides are free until the next counted trade.

Referral

Adds a creator fee on buys and sells (with your core fee at most 10%). On buys from a referred wallet, part of it goes to the referrer, so buyers pay the same with or without a link. A buyer's first referrer is kept for good.

Tithe

A fixed share of every trade goes to a recipient named at launch: a charity, a treasury, a DAO. It builds up as a balance the recipient claims. 0x…dEaD burns it instead. Nobody can change it later.

Volatility fee

The first swap in a block sets a reference price. Every later swap in that block pays an extra LP fee for each tick the price already moved, up to a ceiling. Sandwiches and pile-ons get expensive.

Auto burn

On each buy, a share of the tokens bought is burned. Supply only goes down.

Auto-LP

A share of every buy and sell is saved. Anyone can press Compound: half buys the token and both sides become full-range liquidity nobody can remove. Runs only while the price is calm, at most every ~40 seconds.

Beacon

Keeps the token's highest dollar market cap on-chain for Entangled tokens. A new high only counts once it has held for 15 minutes across 5+ blocks. Takes no fees.

Buyback & burn

A share of what every sell pays out is saved, then spent buying the token and burning it, capped per run, with at most 5% price impact against an older price and a cooldown.

Buyer rewards

Stock a vault with any ERC-20. Every qualifying buy earns the buyer a fixed reward, locked for a while: selling or sending during the lock forfeits it back to the vault, so buy-and-dump loops earn nothing.

Entangled

No buys and no sells until the beacon token first reaches the target dollar market cap, then free forever. Unlocks anyway after the maximum lock time so holders are never stuck.

King of the Hill

The largest qualifying buy holds the crown and earns a share of every buy and sell. A challenger must beat it by the margin, and that bar halves every decay period. Selling or sending any token gives the crown up.

Last-buyer pot

A share of each buy fills a pot. Every qualifying buy restarts the clock and takes the lead. When the clock runs out, the leader takes the whole pot and a new round starts.

LP rewards

A share of each pool buy is donated to in-range liquidity. The launch liquidity is locked forever, so this deepens your LP fees and rewards anyone who adds full-range liquidity later.

Nth-buy pot

A share of each buy (and the pool anti-snipe tax) fills a pot. Each qualifying buy moves a public counter by one, at most once per block, and the buy that lands on N wins the pot. Deterministic, no randomness claimed.
