Ruya Token - Smart Contract Audit Report
Summary
Ruya intends to build a "Dream Interpretation" application that is fueled by the blockchain through their native $RUYA Token.
We audited Ruya's token contract at 0xd898fa530ab04f64ba916f7ed7e49a690b9a87f6 on the Binance Smartchain mainnet.
Notes of the contract:
- The total supply of the token is specified upon deployment of the contract and minted to the deployer's address.
- The total supply of the Testnet token is set to 100 million $RUYA [100,000,000].
- At the time of writing this report, 75% of the total token supply is currently held in an Unverified Contract.
- Another 15% of the total supply is in possession of the Deployer's address.
- 0.34% of the total supply is in PancakeSwap V2 Liquidity. Out of that liquidity, 99.46% of the LP Tokens are held in an unverified contract.
- No minting functions are accessible beyond deployment.
- The circulating supply can be decreased if a holder elects to transfer their tokens to the 0x..Dead address.
- There are no fees applied on $RUYA token transfers other than the gas costs to execute the transaction.
- Holders (that have the approval and allowance to do so) may transfer tokens from another holder's wallet to any recipient.
- The contract is deployed with Solidity version 0.8.5 which will prevent overflow/underflow issues.
- The contract complies with the BEP20 Token Standard.
Ownership Controls:- There are not any ownership-restricted functions present.
