Overview
The Reactive Network reads event streams and enables transactions across different ecosystems. An Origin acts as an event log provider, delivering events to reactive contracts within the Reactive Network. A Destination is the ecosystem where the actual state transition (transaction) takes place.
Origins and destinations don't have to be the same. Reactive contracts can be configured to work with multiple origins, and the system allows for multiple destinations, enabling conditional selection of which destination ecosystem will be used.
Callback Proxy Address
The Callback Proxy address ensures the validity of a callback transaction by enforcing two key conditions. First, it checks that the callback is genuinely initiated by the Reactive Network by verifying that the sender address matches the Callback Proxy address. Then, it confirms the legitimacy of the callback’s origin by checking the RVM ID embedded in the transaction payload, which should correspond to the intended reactive contract.
Some networks are currently unable to act as destination chains because the callback proxy contract has not yet been deployed on them. In such cases, it is recommended to use Hyperlane as the cross-chain message relayer.
