ElectricArena Token - Smart Contract Audit Report


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.
