Interacting with the mStable protocol is permissionless and non-custodial. Anyone can build a service to capitalise on the composibility offered through mStable's smart contracts.
How can I access the mStable protocol?
The protocol exists as open-access smart contracts on Ethereum and Polygon, meaning interacting with the protocol is permissionless - anyone can build a dApp layer or communicate directly with the blockchain to access the mStable protocol.
One such app is the mStable App: a slim, user focussed web application which allows users to:
Deposit assets into or withdraw assets from the Save contract
It is possible, but not recommended to communicate directly through a Wallet provider (e.g. Metamask, MyCrypto). Doing so means writing your own transaction, which is something you should generally avoid doing.
