BenFen’s gas fee mechanism is carefully engineered to minimize transaction costs and optimize user experience.

Gas Pricing Formula

The total gas fee paid by users is calculated based on computation and storage costs, minus any storage rebate:

Net_gas_fees = (computation_units * reference_gas_price) + (storage_units * storage_price) - storage_rebate

Reference Gas Price Proposed by validators at the beginning of each Epoch and dynamically determined using the 2/3 weighted median, ensuring gas prices reflect market conditions.
Storage Rebate When a transaction deletes previously stored data, the system refunds a portion of the storage cost, encouraging efficient use of on-chain storage.

Gas Payment Options

BenFen natively supports multi-token gas payments:

BFC: the native payment token.
Stablecoins: Users can directly pay gas fees on whitelisted stablecoins such as BUSD. A small conversion spread is applied, and the system automatically converts the payment into BFC behind the scenes.
User-Issued Tokens: With community governance approval, project-issued tokens may be added to the gas payment whitelist.
