Swap crypto

You send from your own wallet straight to the exchanger — nothing to connect, no account, and you stay on this page throughout. Rates are indicative until a swap is opened.

The swap is carried out by an independent exchanger and the deposit address above is theirs. starname.me never holds, receives or controls your funds, has no key to that address, and earns a referral commission. Opening a swap sends your receiving address, IP, browser and timezone to the exchanger for their compliance checks; we store none of it. Check their terms, fees and country restrictions before sending anything.

Moving btc between chains without wrapped tokens

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.
