Gain Chain is a peer-to-peer network platform where the asymmetric swap is kept safe. Cryptocurrencies are irreversible due to their nature. If you incorrectly enter one letter of the address you are processing, the transaction is considered invalid. Gain Security Pool aims to resolve the mentioned problem. It prevents the same order from being placed a second time in the system by matching the placed orders to the system and using the Shamir Secret Sharing Scheme. They use ERC-20 Smart Contract, on which users’ information can be kept safe.
