PETRO is the governance token of PETRO.finance, a decentralized lending aggregator (platform that aggregates liquidity from various sources) running on the TRON blockchain. It standardizes interest rates across decentralized lending platforms, helping users place their assets on the lending protocols with the highest interest rates. It automatically transfers funds through smart contract interactions when interest rates fluctuate on these lending protocols, ensuring that funds are always in the highest-yielding lending protocol. 5% of the machine gun pool profit goes to the developer fund. (1% is a harvest bonus, 1% is an insurance reserve, and 3% is used for PETRO market buyback and burn.)
