# Router EVM Gateway contracts

## Overview

The Router EVM Gateway contract will bridge EVM chains with the Router Chain.
We can deploy this gateway contract on any EVM-compatible chain.
The gateway contract validates all incoming requests coming from the router chain using the
validator set signatures. These signatures should have at-least 2/3 validator power.
The current validator set(valset) can update the validator set to a new valset by invoking the _updateValset_ function.

The Gateway contract has a function iSend to send request to other chains, a function iReceive to receive requests from another chain and iAck to receive acknowledgments back from destination chain.
