Reserve is a stablecoin consisting of two ERC-20 tokens, the Reserve token and the Reserve Rights token, both of which are mintable and burnable. The Reserve Manager manipulates the supply to keep the price stable at $1, buying and burning tokens if necessary. The company is preparing for a self-custody version of their app by forking the RSV contract and adding meta transaction support and a Reserve Relayer, enabling on-chain RSV payments without the need for ether.
