SX Network leverages Polygon security through the practice of state checkpointing. This is similar to how Polygon functions, but SX uses Polygon directly as its host chain. By doing so, SX is SX Network able to utilize Polygon as its main bridge but still be connected to other EVM-compatible chains such as Ethereum, BSC, Fantom, etc. This makes it trivially easy, and extremely fast and secure to transfer assets to the SX Network from other blockchains. It also enables SX Network to leverage Polygon's security but offer developers ultra-low transaction costs. SX Network will have the lowest gas costs in the entire EVM space without sacrificing security.
