Trading overview

Every coin launched on Archr trades on a standard Uniswap V3 pool paired against WETH. If you can swap on Uniswap V3, you can swap on Archr.

​

The pool

Every Archr pool has the same shape at launch: This is the “single-sided sell wall” model: the pool is created with only the coin side seeded. The first buyer trades ETH into the pool and gets coin back, which pushes the price up through the tick range. Each subsequent buyer pays a higher marginal price than the last.

​

How price discovers

The pool prices as any V3 pool from block one: sqrtPriceX96 at the launch tick, moving up as coin flows out. There is no bonding curve, no graduation event, no “phase 1 vs phase 2.” Every buy and sell trades against the same locked LP position, and the fee-per-swap goes straight into the position’s fee bucket. Traders on the sell side (holders who bought earlier, want to exit) fill the “buy side” of the pool as they sell. The pool accumulates WETH from their sales, and later buyers face a mixed WETH+coin book like any V3 pool that has seen two-sided flow.

​

Fees

A 1% fee is taken on every swap, added to the LP’s fee bucket. Because the LP position is locked forever, the fee bucket is the only value that can ever leave the position. See ARCHR fee-flywheel for how those fees get recycled. From the trader’s perspective, the 1% is a normal V3 fee, and every V3 aggregator will quote it correctly. There is no separate protocol fee at the trade level.

​

Where to swap

Every coin’s page at archr.win/token/<address> has a built-in swap widget wired to SwapRouter02 on 4663. It handles the WETH wrap/unwrap and the slippage check for you. Because the pool is a plain V3 pool, anything on 4663 that speaks V3 also works:

• The canonical Uniswap V3 SwapRouter02 at 0xCaf681a66D020601342297493863E78C959E5cb2.
• Any aggregator or wallet that supports 4663 and V3 pools.
• Direct exactInputSingle / exactOutputSingle calls from a smart contract or script.

​

Slippage

The swap widget’s default slippage tolerance is picked to catch normal V3 volatility on 4663. If your swap reverts with a slippage error, raise the tolerance or wait for the pool to settle. For very large trades, split into smaller pieces to reduce marginal price impact.

Verifying a coin before you buy

Anyone can launch anything, and there is no global uniqueness check on name or symbol. Before you buy:

1. Verify you have the right contract address; do not trust the symbol alone. Coins are found by address, either from the trigger reply (Reddit / X) or the coin’s page URL on archr.win.
2. Open the coin on Blockscout and confirm the fixed supply is 1,000,000,000e18 and that the LP NFT for its pool is held by one of the Archr launcher contracts. That is the “liquidity is locked” invariant.
3. See risks for what platform-locked LP does not protect you against (market risk, price manipulation, coin-specific launcher intent).
