    I would like to migrate an existing project from Terra to Solana to take advantage of the Solana's speed and low transaction fees. The current project on Terra is named Mirror Protocol and can be found at https://mirrorprotocol.app. The Solana version would ideally be extremely similar to the existing dApp. This will allow the reuse of code and documentation. However, the smart contacts will have to be implemented as programs on Solana. Fortunately, both blockchains use the rust language so that should make porting a bit easier. The Mirror Protocol project is opensource and code can be found on github ().
