Frequently asked questions

No. PEX is self-custody. Your wallet signs every transaction and your funds move directly on-chain — PEX never receives a deposit or holds a balance for you.

No account, no sign-up, and no identity check. Connecting a wallet is all that's needed to get a quote and swap.

Ethereum, BNB Chain, Polygon, and Solana on mainnet, plus Sepolia, BNB Testnet, and Polygon Amoy for practice swaps with free test coins.

A same-chain swap usually settles in one block — seconds to a minute. Cross-chain routes depend on the bridge involved and typically finish in a few minutes.

You pay the network gas fee and whatever the underlying liquidity route charges. The estimate shown before you confirm already includes those costs.

Prices move. Quotes refresh regularly, and slippage tolerance protects you from receiving less than expected — if the market moves past it, the swap reverts instead of filling badly.

A practice mode. Switch the swap box to Testnet, grab free coins from the linked faucet, and run a real on-chain transaction that costs nothing of value.

A reverted transaction returns your funds minus the gas spent. If a cross-chain swap looks stuck, open the explorer link and send us the transaction hash through Support.

Once a transaction is signed and broadcast it can't be cancelled. Review the route carefully before confirming.

PEX never asks for a seed phrase or private key and never requests unlimited spending approvals you can't revoke. Always confirm you're on the correct domain before connecting.
