# VotingEscrowMock

*LevX (team@levx.io)*

> Voting Escrow

Votes have a weight depending on time, so that users are         committed to the future of (whatever they are voting for)

*Vote weight decays linearly over time. Lock time cannot be      more than `MAXTIME`.Ported from vyper (https://github.com/curvefi/curve-dao-contracts/blob/master/contracts/VotingEscrow.vy)*
