Impossible to transfer VE tokens

Lines of code Vulnerability details Impact In VoteEscrowDelegation.sol, function transferFrom will attempt to remove the delegations to the token transferred. // remove the delegation this.removeDelegationtokenId; However this external call will change msg.sender to addressthis, reverting the cal...

delegate will revert for tokenIds which have no prior checkpoints

Lines of code Vulnerability details Impact For a tokenId without a prior checkpoint, calling VoteEscrowDelegation.delegate would revert due to an underflow in nCheckpoints nCheckpoints variable in uint256 nCheckpoints = numCheckpointstoTokenId; is set to 0 since there was no prior numCheckpoints...

Impossible to delegate

Lines of code Vulnerability details Impact It's impossible to delegate to a token, because the first delegation will always revert. Consider there's no delegation so far, meaning that every token will have numCheckpointstoken = 0. When calling delegate, we will have nCheckpoints = 0 and the call...
