How to convert crypto: on-chain vs off-chain
Off-chain (on an exchange)
Your trade happens inside the exchange's own ledger. Nothing touches the blockchain until you withdraw.
- Cheapest and fastest for common pairs
- Needs an account and usually ID verification
- The exchange holds the coins until you withdraw them
- Best for converting to and from cash
On-chain (a DEX or swap)
You swap from your own wallet. The transaction settles on the chain and you pay its fee.
- No account, no custodian — you keep the keys
- You pay network fees, which vary a lot by chain
- Small or new tokens often only trade here
- Slippage and thin liquidity are real costs on low-volume pairs
Before any on-chain swap: check the token's contract address
against a block explorer, start with a small test amount, and review what you
are approving — an unlimited token approval to an unknown contract is how most
wallet drains actually happen.
