FIFO Finance

FIFO stands for First In, First Out. 该系统确保用户是第一个采取行动的人, regardless of buying, selling, or any other interaction.

市场上的大多数系统依赖于用户提供他们的网络节点，或者依赖于公开可用的节点基础设施. We have created our system from scratch, 不妥协地专注于性能和减少延迟，特别是对于链上高频执行的任务, including detecting and broadcasting transactions, as well as on-chain execution simulation.

资金存放在链上的智能合约中. 用户决定他们希望该合约拥有什么权限, 例如购买特定的令牌并将其发送到他们的钱包.

OSOK Finance

OSOK是一个快速的令牌狙击手，确保用户可靠地接收令牌, at the best possible price, 在去中心化或中心化交易所启动后立即启动. 一组具有有限权限的链上智能合约允许OSOK团队维护专有的执行基础设施，并将用户的资金严格限制在批准的代币购买范围内.
