To swap an ERC-20 token, your wallet will ask you to approve OpenOcean's router contract to move exactly the amount you're swapping — never an unlimited allowance by default. Native tokens on each network (ETH, BNB, etc.) don't need this approval and go straight to the swap transaction. Latin Link never asks for your private key or seed phrase.
Now that you know how Latin Link works, there's just one thing left: connect your wallet and discover a smarter way to swap crypto.
