# Questions about the USDFI ecosystem

### What’s the difference between the USDFI and STABLE tokens?

STABLE is the ecosystems governance token, while USDFI is the ecosystem’s native, decentralized stablecoin. Please refer to the documentation for more info [here](https://docs.usdfi.com/)

### Is STABLE a native BNB chain token? What about USDFI?

STABLE is a multichain native token, just like USDFI. It’s native on the BNB chain and all other EVM compatible chains and features the same hash on all chains.

### The USDFI protocol is a buyer of last resort and automated market maker of last resort of last resort. What does that even mean?!

The buyer of last resort (BLR) is a mechanism used DeFi to stabilize the price of a specific cryptocurrency. It is based on the concept of the lender of last resort in traditional monetary systems, where a central bank acts as a lender of last resort to stabilize the financial system.

The protocol’s treasury automatically engages as a BLR and redirects its revenues to buying back unlimited USDFI at a higher price, in perpetuity, until price stability at the peg is reinstated.

The automated market maker of last resort (AMMLR) is a mechanism used in DeFi to stabilize the price of a specific cryptocurrency by providing liquidity to the market. For example, when the price of a cryptocurrency drops, the AMMLR mechanism is triggered and uses its revenues to buy the cryptocurrency at a discount, providing liquidity to the market, and helping to restore price stability. The opposite occurs when the price of a cryptocurrency rises, the AMMLR mechanism sells the cryptocurrency at a premium, providing liquidity to the market, and helping to restore price stability. Both mechanisms are unique to USDFI.
