ElectricArena Token - Smart Contract Audit Report

Summary

Electric Arena Audit Report ElectricArena Token ($eArena) is a new ERC20 token on the Ethereum Blockchain.

For this audit, we analyzed ElectricArena's Token contract. We reviewed the team's code at the following address on the Ethereum mainnet: 0xc30590a879c7dd78bcd9a18e48de446a3c7c98b8

Notes on the Contract:
The total supply of the token is initially set to 1.15 quadrillion [1,150,000,000,000,000] $eArena.
No mint or burn functions are present beyond deployment; though the circulating supply can be reduced by sending tokens to the 0x..dead address if desired.
At the time of writing this report, 17.91% of the total token supply is held in Uniswap v2 Liquidity.
Out of that liquidity, 99% is held in a UniswapV2Locker Contract and will vest to the team on Monday, November 22nd, 2021.
The Owner is in possession of 11.54% of the total supply.
The next largest wallet holds 1.48% of the total supply.

There is a 5% fee applied on transfers when the holder is either buying or selling $eArena. The tokens collected from fees are stored in the contract address.
Once the contract balance reaches a value of 50 billion $eArena, the tokens will be swapped for ETH and sent to the owner. The owner has the ability to update this threshold value at any time.
The owner is excluded from fees during transactions.
The owner has the ability to airdrop any amount of tokens to any address at any time.
A for loop is used to transfer funds for the airdrop; The team must ensure the maximum number of addresses that can be involved in a single airdrop is no more than 350 to prevent this loop from hitting the block gas limit.
As the project is implemented with Solidity v0.8.x, it is protected from overflows.
The contract complies with the ERC20 Token standard.
Audit Findings Summary
No external threats were identified.
Please ensure trust in the team prior to investing as they have some control in the ecosystem.
Date: September 19th, 2021
Updated: September 27th, 2021 to reflect the mainnet deployment.
