## Verdict (BLUF)

Centralised exchange vs On-chain DeFi in 2026 — CEXs suit fiat on-ramps and simple spot trading; DeFi suits self-custody, composable yield, and permissionless access — many users combine both.

## Comparison table

| Criteria | Centralised exchange | On-chain DeFi |
| --- | --- | --- |
| Custody | Exchange holds assets | You hold keys via wallet |
| KYC | Required for most fiat rails | Not required at protocol level |
| Products | Spot, perps, earn, staking | Lending, DEX, LST, perp DEX |
| Composability | Siloed account balances | Protocols stack (e.g. LST → lend → borrow) |
| Counterparty risk | Exchange solvency/regulatory | Smart contract + oracle risk |
