OneSwap charges the Taker a fixed 0.5 % of transaction fees based on the transaction amount, while Maker does not need to pay. The transaction fees generated in the Pair contract are divided into two parts: 60% that directly goes to the liquidity provider, and 40% to repurchase and burn ONES. ONES is a deflationary token in that it is repurchased and burned automatically by the token repurchase contract.
Miner Fee (Gas)
ETH transfer fee is calculated based on Gas ( fuel ) consumption. (ETH miner fee = Gas Limit x Gas Price)
Ethereum introduces the concept of Gas. Each calculation during transaction process needs to consume Gas, and Ethereum specifies the amount of Gas consumption for all operations and contracts. So, in other words, Gas reflects the "workload" of each transaction. A transactions with low workload consume a small amount of Gas, while a transaction with high workload consume a large amount of Gas. Therefore, Gas is also called the "fuel" of the Ethereum network.
Gas Limit is the maximum amount of Gas consumption that users are willing to pay for a successful transaction. If the actual Gas is over Gas Limit set by the user, then the transaction will be failed; if the actual Gas is under Gas Limit, then the transaction will be successfully and the unused Gas will be "returned" to the user's wallet.
Gas Price is the price that users are willing to pay for each Gas. The unit of Gas is GWEI, 1 GWEI = 0.000000001 ETH.
Calculation Formula: Miner Fee = Gas Amount x Gas Price
Therefore, Ethereum miner fee is calculated based on Gas and paid by ETH.
