An app that moves assets between Ethereum and NEAR. You can use this as the starting point for your own app on the Rainbow Bridge.

Clients. These get raw NEAR data into Ethereum and vice versa. These are light clients that run as smart contracts in each blockchain, with external relays to pipe the data in each direction.

Provers. These are smart contracts that allow making assertions about data stored in the clients.

Connectors. These are smart contract pairs, one on each chain, that provide an interface to apps that want to send certain kinds of data or calls from one blockchain to the other. They use the provers to ensure each operation is valid.
