Trade crypto.
Own your assets.
SellCex is a decentralized exchange. Connect your wallet, swap tokens, and provide liquidity — settled on-chain, held in your own custody the entire time.
Three primitives, entirely on-chain
No middlemen holding your funds, no black-box pricing. Every swap, deposit, and withdrawal runs through contracts you can read yourself.
Swap
Trade any listed token at a rate priced live by the pool's own reserves — no order book, no waiting for a match.
- Adjustable slippage
- Live rate & minimum received
- One approval, then you're done
Liquidity
Deposit a pair of tokens into a pool and earn a share of every trade that passes through it.
- Add or remove anytime
- Track your pool share
- LP position always visible
Wallet
Everything stays in your own wallet. SellCex never holds custody of your funds — the contracts execute, you keep the keys.
- Balances across networks
- Full transaction history
- Nothing leaves self-custody
From wallet to settlement, in five steps
Connect wallet
Link your wallet — no account, no email, no KYC.
Choose a pair
Pick the token you're selling and the token you want.
Router finds the path
The SellCex Router quotes the best rate across pools.
AMM prices the trade
The pool's constant-product curve sets your output.
Confirm on-chain
Sign once. Tokens settle directly to your wallet.
Every pool, every trade, in one dashboard
Track total liquidity, trading volume, and popular pairs as they happen. Nothing is delayed, nothing is cached from a centralized server pretending to be the chain.
Built to be read, not just trusted
The AMM, Router, and Factory are our own implementation, tested with Foundry's fuzz and invariant suites before a single testnet deployment.
Mint, burn, and swap are locked against re-entry.
Every swap is checked to never decrease pool reserves' product.
Minimum-received checks revert trades that move too far.
Stale transactions expire instead of executing at a bad price.
What testers are saying
"Finally a DEX where the pricing curve isn't a black box you have to trust blindly."
"The slippage controls and minimum-received display are exactly what a swap screen should show."
"Watched the router quote update live as I typed. That's the kind of detail that builds trust."

Questions, answered
No. SellCex never takes custody of your funds at any point. You approve a contract, sign a transaction, and tokens settle directly to your wallet.
