VeCRV is a decentralized liquidity pool protocol built on the Ethereum blockchain. It is currently only available on Ethereum's mainnet, but the team is exploring the possibility of expanding to other networks such as Polygon. As Polygon is a layer 2 scaling solution for Ethereum, veCRV could potentially be deployed on Polygon in the future, allowing users to benefit from faster and cheaper transactions. However, the details of this expansion have yet to be announced, so it is unclear when or if this will happen.
