OKC (OKX Chain) has added a Gas Back function, which supports the proportional distribution of transaction fees between block producers and contract deployers. This function will distribute the transaction fee for calling a certain contract to the deployer of the contract in proportion, thereby incentivizing developers to deploy contracts on OKC and promoting the ecological development of OKC. At the same time, the Gas Back function supports developers to register, modify, and delete dividend contracts. In the initial stage of launch, DApp developers are free to register and participate in fee dividends. According to the vote of the OKC community, the dividend ratio is up to 50%.
