SlowMist Completes Security Audit for RFUEL Smart Contract

The SlowMist security team has completed the security audit for RioFuel (RFUEL) generation smart contract.

RFUEL is central to the economic model of RioChain, and a core element of the RioDeFi ecosystem. RFUEL is the native token on RioChain, providing the gas required to process transactions or execute smart contracts, and also facilitates staking and validation reward payments.

Following an overwhelming response to the initial community crowdsale for the token, on Monday, September 28 at 08:30 UTC, RFUEL had its Initial DEX Offering (IDO) on Uniswap.

The next stage in the process will see the RFUEL ERC20 token migrate over to the RioChain standard (RST88), upon launch of the RioChain mainnet.

SlowMist Report Findings

In summarizing the RFUEL smart contract security audit report, the SlowMist team stated:

“This is a token contract that does not contain the tokenVault section. The total amount of contract tokens can be changed, users can burn their tokens through the burn function. The minter role can mint tokens through the mint function, but the total amount of tokens is capped.

“OpenZeppelin’s SafeMath security module is used, which is a commendable approach. The contract does not have the Overflow and the Race Conditions issue. The comprehensive evaluation contract is no risk.”
