TrustSwap is a distributed platform, cryptocurrency and protocol that promises a new evolution to decentralized finance (DeFi). It aims to achieve this through next-generation multi-chain token swaps and other functionalities that aim to solve existing problems with split payments, subscriptions and cross-chain token swaps.
TrustSwap describes its mission is to power "customizable transactions," not only for the DeFi space but also for the entire crypto industry. Incorporated in July 2020 in Canada, the platform seeks to take smart contracts mainstream.
Among TrustSwap’s primary products are staking, smart locks and smart swaps, which can wrap any coin or token into an ERC20 token. For example, the protocol offers cryptocurrency wrapping services which enables anyone to wrap and use any cryptocurrency on the Ethereum blockchain. Also, it features escrow services enabling it to become a trusted middleman in crypto-based financial transactions.
