The Maker token (MKR) is the MakerDAO native token. It acts as a utility token, governance token and a recapitalization tool for the MakerDAO platform, which manages the DAI stablecoin. MKR is used as part of the stabilizing mechanism that is in place to combat the price volatility of the DAI stablecoin.
DAI is pegged to the US dollar and has collateral in place to ensure stability. The MKR token is used is to pay for the "collateralized debt positions" (CDPs) that have been used to generate DAI. After this MKR is used, it is removed from the supply. MKR holders also contribute to the governance of the MakerDAO and vote on crucial issues related to the direction of the DAI stablecoin.

The JUST token is used as stabilizing mechanism for the JUST network, which is a stablecoin network built on top of the TRON blockchain. TRX token holders can purchase the USDJ stablecoin, which is pegged to the US Dollar through collateralized debt positions. The TRX tokens are held as collateral, and when the user wants to redeem their TRX tokens, they must pay a stability fee using the network's JUST token.
