Vetter Token, where crowdsourcing meets a.i. and gamification to empower the crypto investor. Reinventing the Crypto Research Game.

Vetter Token, helping crypto insiders become a better Vetter. Crypto Calendar helps identify the projects most likely to 2x to 1000x based on poster history.

Vetter Token (VETTER) makes crypto research fun! With a proven use case, the dApp highlights projects worth researching by ranking the poster’s performance. Add in compensation, points, tipping and a bad-ass interface, and you have the best crypto research tool at your fingertips.

Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

VetterToken.addLiquidity(uint256,uint256) (#402-416) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),getTime()) (#408-415)
VetterToken.transferBNBToAddress(address,uint256) (#825-828) sends eth to arbitrary user
Dangerous calls:
- recipient.transfer(amount) (#827)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
