Skip to contentBuy a token
What happens when you press Buy, and why a buy can be refused.
Open a token page, read its mods and risk report, enter an amount, press Buy. If the Site gate is active, the site asks for what the mods require (a captcha, your X account) and signs a ticket for your buy. Your wallet then signs the transaction.
Prices and slippage
Buys and sells on Mods carry a 10% slippage guard computed from a live quote of the curve.
Why a buy can be refused
Refusals come from the token's mods. They are shown in your wallet or on the page with one of these names:
| Error | Meaning |
|---|---|
| NotThroughGate | Buys go through the site right now. Buy from the token page on Mods. |
| NotOpenYet | Buys have not opened yet. |
| OutsideTradingHours | Outside the token’s market hours. Selling still works. |
| Blocked / NotAllowed | Your wallet is on the block list, or not on the allow list. |
| BuyTooLarge / SellTooLarge | The trade is bigger than the share of supply allowed per trade. |
| WalletTooLarge | After this buy you would hold more than the max wallet. |
| PriorityFeeTooHigh / TipTooHigh | Your priority fee or Jito tip is above the launch’s sniper cap. |
| SameSlotRoundTrip | You traded the other way in the same block. Wait a moment. |
| SlotFull | Too many trades in this block. Try again. |
| DevLocked | This wallet is locked by the creator’s dev lock. |
| CurveCeiling | A forever curve is full. Selling still works. |
| OverCap | You reached the cap per person for this launch. |
| CoolingDown | Wait a little between two buys. |
The risk report
Every token page reads the chain and flags what matters: does the creator hold unlocked tokens, how concentrated are the top holders, can bots sandwich you, do sells depend on the site. Green is good, amber is worth knowing, red is a risk.
Selling
Selling is always possible, except for wallets under a dev lock. During a site-only phase that also covers sells, sell from the token page; if the site is down, the kill switch opens everything within 10 minutes.
