All you need to do is:

Any token on the following networks can be custom added to swap on 1inch:

Arbitrum

Avalanche

Base

BNB Chain

Ethereum Mainnet

Gnosis

Optimism

Polygon

zkSync
Base

Aurora, Kaia and Fantom have been deprecated. You can find more information in this article.

1) If you don't see the token in the drop-down menu, it can be manually added with its contract address (the suggested source for finding the contract is coingecko)

2) If swapping on Classic mode, check that you have approximately sufficient native tokens on your balance to cover potential gas costs when approving and swapping.

3) Do not reduce the gas price or the gas limit, this will significantly increase the risk of transaction failures. Also, adjust slippage tolerance as needed.

4) When using Fusion mode for the first time, you must have a sufficient balance of native tokens to grant smart contract permissions. The swaps themselves are gasless — they don’t require native tokens to execute. Instead, the transaction cost is deducted by slightly reducing the amount of the token you receive.

5) Use Cross-chain to swap tokens across chains (i.e. from Ethereum to BNB Chain) through 1inch. Read more about Fusion+ here
