# SERVICE: ENTERPRISE BLOCKCHAIN SMART CONTRACT GAS-FEES
We must **monetize the Pharmaceutical Tokens (Ticker: PHARMA) workflows** and development loops in order to keep our own organization's "gas tank" full on the Blockchain.
For our type of "Never Been Done Before" Operation**, Ethereum Charges Gas-Fees**, and Blockchain BioPharma **will Charge Gas Fees** on top of this Ethereum Gas-Fee as a Smart Contract Audit and Regulatory Compliance Review Fee.
The average proposed Gas-Fee, from the Blockchain BioPharma perspective, would be around $10,000 USD in Ethereum as our fee to "Audit" almost every Smart Contract that's written to our Blockchain.,
This solution also provides us a higher-level of security. We propose to use several Blockchain Audit firms, including **#KPMG** and **#OpenZeppelin**.
Auditing Smart Contract is imperative and will **reduce our risk of fraud or security vulnerabilities.**
