MetaPad - Audit Report

Summary

MetaPad Audit Report MetaPad ($MPD) is a new community-driven DeFi token on the Binance Smart Chain.

We reviewed the MetaPad Token contract at 0xD88C6Ec2D3fBD90892c6749CF83De6ad10c30B4b on the Binance Smart Chain mainnet.

Notes on the Contract:
The total supply of the token is set to 100 million [100,000,000].
No mint or burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
At the time of writing this report, 69.5% of the total supply belongs to a token locking contract behind a proxy.
The next holder owns 25.5% of the total supply.

No ownership-restricted functions are present.
The contract complies with the BEP20 token standard
As the contract is deployed with Solidity v0.8.x, it is protected from overflows.
Some gas optimizations can be achieved through declaring functions external instead of public. As this contract is already deployed, this is merely informational.

No external threats were identified.
Date: November 26th, 2021
