The underlying consensus mechanism, network congestion, transaction complexity, and other factors all affect transaction fees in blockchain networks like Ethereum.

These fees are essential for compensating miners or validators who maintain the network's security and integrity. However, high transaction fees can be a significant barrier, especially for small-scale transactions or during periods of high network congestion.

For users, this means balancing the need for quick confirmations with the cost of transactions. In times of peak demand, users might face exorbitantly high fees, impacting the feasibility of executing transactions, particularly for those in decentralized finance (DeFi) or regular small transactions.

The Role of Relayers and Gasless Transactions

To address the challenges of high and unpredictable fees, the concept of relayers and gasless transactions has emerged.

Relayers are entities that facilitate transactions on behalf of users and cover the initial gas costs.

They typically work within specific frameworks where the transaction costs are either subsidized or later reimbursed by the user in a different form, often a token specific to the platform or application.

Gasless transactions, often facilitated by relayers, are a user-friendly approach to blockchain interactions, removing the immediate burden of gas fees from the user.

This system is particularly beneficial for new or casual users who may not hold the native cryptocurrency of the network but still wish to interact with dApps or execute transactions.

Example Calculations of Transaction Costs

To understand the economics of transaction fees better, let's consider a typical scenario on the Ethereum network.

Example Calculation  Assume a deposit of 100 MATIC in Biconomy's gas tank contract on Polygon to sponsor gasless transactions: Method Gas Requirement: 21,000 units Network Gas Price: 200 Gwei Standard Gas Fees: 21,000 * 200 Gwei = 0.0042 MATIC Biconomy Markup: 12% * 200 Gwei = 24 Gwei (below 40 Gwei cap) Total Gas Fees (with markup): 21,000 * 224 Gwei = 0.004704 MATIC Total Deduction: 0.004704 MATIC Remaining Balance in Gas Tank: 99.995296 MATIC

Example calculation extracted on January 30, 2024, 11.00 GMT.

As you can see, using Relayer reduces the fees by 8-12%.
