In Brave Wallet, swaps refers to the exchanging of one token for another.
A crypto swap is a transaction that allows you to exchange one token for another without having to go through a centralized exchange. In a Brave Swap, you essentially trade one cryptocurrency for another, and the transaction is settled on a decentralized exchange (DEX).
Brave uses 0x and Jupiter as decentralized exchange aggregators, which searches for the best possible exchange rates across a variety of decentralized exchanges. By using an aggregator for swaps, this helps with the efficiency and cost-effectiveness of the swaps, and minimizes the amount of slippage and overall transaction fees.
