What is a Non-Custodial Exchange?. A non‑custodial exchange lets you trade without giving up your keys, usually through a DEX or aggregator.
How it works
You approve token spending and sign swaps; contracts execute and return assets directly to your wallet.
Why it matters
Self‑custody reduces counterparty risk while keeping markets accessible.
Common pitfalls
- Approving malicious routers
- Forgetting to revoke allowances
- Trading thin pairs with large orders
Quick example
You aggregate quotes from several DEXs and execute the best route without depositing funds to an exchange.
