User Guide

The criteria that need to be met for a "0-gas" swap:

1. Tokens need to be on BSC, Polygon, HECO, and OKExChain;

2. Insufficient funds for mainnet tokens;

3. SWFT channel

Users of the MetaMask wallet need to enable the "Toggle eth_sign requests" function, steps as following:

1. Select a token as the From token (if it's a mainnet token, it means there is enough balance to pay for the gas fee, so the 0-Gas service won't be triggered). When exchanging, make sure there is not enough mainnet token to pay for the gas fee. Take the HECO chain as an example. Select SWFT as the Exchange Path (0-gas Swap is now only available on SWFT path), and if you click on the blue pompts, it will redirect you to a relavent instruction page. Once you select the path, click on Swap.

1. If you click on the blue prompt, it will redirect you to a relavent instruction page as well. Check your swap information, and then click on Confirm Swap.

1. There is also prompt on the top of your order page, click to see the related instruction.

2. The completed order will have relevant identifiers and fields of the 0-Gas Swap service.
