4swap is a decentralized protocol implement for automated liquidity provision on Mixin Network
go get github.com/fox-one/4swap-sdk-go/v24swap supports two kinds of access tokens:
- the access token that complete the OAuth flow at 4swap's webpage: https://app.4swap.org
- the access token that generated by your own Mixn Application. The token should sign the URL /me and the scope should be "FULL". Please read this document for more details.
