Bridge is an application for token transfer between different blockchain networks. It helps a project to scale better and create its own ecosystem. Our solution works entirely autonomously, being gas-free for the project. To ensure security, it uses signatures technology.
There is an opportunity to define the amount and types of blockchains that should become compatible through the Bridge. It is also possible to set a commission for the transfers of cryptocurrency.
Overall, Bridge consists of front-end, back-end, and smart contracts that belong to their own blockchain. A user has to make two transactions because a transfer executes between two networks. Thus, the first transaction is sending of tokens to the smart contract of the first blockchain. After this, it is possible to get tokens from the smart contract of the second blockchain.
The development process implies setting up and deployment of smart contracts on each blockchain of a Bridge. It is also necessary to load a sufficient number of project tokens there. The back-end signs the transactions and checks the token transfers between blockchains. Front-end provides the user with the aforementioned functions, and it is designed for easy interaction with the Bridge.
Bridge development takes at most 1 week.
