Pay with what you hold
Paying in the pair is one swap. Paying in anything else, the panel first
routes your asset into the pair through an aggregator, then completes the
pool swap: two swaps in one flow. Most stock pairs route from ETH too; the
exception is the Coinbase B20 stocks on Base with no on-chain market,
where you must hold the stock already and the panel says so.
Before you press the button, the panel shows Wallet signatures: how
many times your wallet will ask you to sign, counting any token approval
it needs first. The approval for the pool is given once per token, not
once per trade.
Approve and trade in one signature
Some wallets can send an approval and a trade together as one request. Smart wallets usually can. The panel uses this when three things are true: your wallet says it supports it, the trade needs an approval, and the trade goes straight to the pool (you pay in the pair, or you sell the token for the pair). First the panel simulates the approval and the trade together. If that passes, your wallet asks once and the panel shows Approve and trade in wallet…. Beforehand, Wallet signatures reads 1 if batch preflight passes; otherwise the usual count. If the simulation finds the trade would fail, nothing is sent and the panel shows the error. If the simulation cannot run at all, the trade takes the usual path: approve first, then trade. A routed trade, paying in ETH or another asset, always takes the usual path.What you pay
The token’s tax - buy and sell rates set at launch, shown on its page, taken inside the swap from what you receive: in the token when you buy, in the pair when you sell. There are no platform charges on top. Price impact is the pool’s own curve; split a large order rather than raising slippage.The sell floor
Every pool opens as single-sided liquidity above the launch price. Two guarantees follow. Nobody can pull the liquidity - the launcher holds nothing after launch and no admin exists over the pool. The launch price is a floor - the pool cannot pay out below the price it opened at, because below it there is nothing on the other side.The one consequence
While a token trades near its launch price, the pool has not collected much of the pair yet. A very large sell can ask for more than the pool holds - and is refused whole rather than partially filled.Not a honeypot, nothing is locked. Selling in smaller pieces always works, and the interface tells you when a sell is too big. A token that has traded up sells normally.
Charts and data
Live candles, trades, holders and tax mechanics on every token page, from BaseStonk’s own indexer - the same numbers the API serves. On Base, a new trade shows in the trade feed and on the chart within a couple of seconds of its block.Price impact, and why size matters more than slippage
Price impact, and why size matters more than slippage
- your effective price worsens with size relative to the pool. A $500 trade is small in a deep pool and enormous in a thin one. If your size is near what moves the pool 2%, split the order; raising slippage widens what you accept, not what you pay.
Why the floor holds
Why the floor holds
A concentrated position releases for a move. That is what depth means throughout this venue: not a balance, but what comes out for a given move. It is why routes are ranked by what a move releases, not by pool size.
