#1 Missing requirement check address
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/governance/GolomToken.sol#L36

Add simple check e.g require( _account != address(0))
#2 Missing emit transfer of mint
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/governance/GolomToken.sol#L36

https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/governance/GolomToken.sol#L42
add emit transfer for mint, check OpenZeppelin docs.
#3 Remove when contract will be deploy
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/vote-escrow/VoteEscrowDelegation.sol#L6
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/vote-escrow/VoteEscrowDelegation.sol#L218-L225
remove that code before deploy the contract. if the code have been remove it make increase readibility too
#4 Missing natspec parameter nCheckpoints
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/vote-escrow/VoteEscrowDelegation.sol#L94
the parameter function have natspec comment. add natspec comment on parameter in the function parameter nCheckpoints
#5 Missing natspec parameter _sender
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/vote-escrow/VoteEscrowDelegation.sol#L237
the parameter function have natspec comment. add natspec comment on parameter in the function parameter _sender
#6 trader must be immutable
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/rewards/RewardDistributor.sol#L44
the state trade can't be initialize by constructor. the constructor parameter mention state trader to initialize. so i suggest to add immutable on trader.
#7 Typo
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/rewards/RewardDistributor.sol#L111
change begiining to begining to avoid misleading.
#8 Comment with code doesnt match
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/rewards/RewardDistributor.sol#L112
missmatch betwen comment line 110 and the code 112. fix it because it make user confuse where is the true code.
#9 governance must be immutable
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/core/GolomTrader.sol#L72
the state trade can't be initialize by constructor. the constructor parameter mention state governance to initialize. so i suggest to add immutable on governance.
#10 Missing field index tokenId
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/vote-escrow/VoteEscrowCore.sol#L284

event is missing indexed fields. Add indexed at tokenId.
#11 Missing check address and Emit transfer
https://github.com/code-423n4/2022-07-golom/blob/7bbb55fca61e6bae29e57133c1e45806cbb17aa4/contracts/vote-escrow/VoteEscrowCore.sol#L629
add requirement check and emit transfer for safetransferFrom. check OpenZeppelin for detail.
