Biconomy's Gasless SDK is tailored for the ERC-2771 standard, allowing dApp developers to subsidize gas fees and offer a seamless Web2-like experience. Unlike bundlers that operate under the ERC-4337 standard, Gasless SDK focuses on simplifying user interactions with Externally Owned Accounts (EOAs). If you prefer not to use Account Abstraction (AA), Biconomy's Relayer API is still available to ensure a frictionless user experience.

Pricing

We add a gas price premium to each blockchain operation in the Galsess SDK (EOA wallets). The percentage premiums for each chain are mapped out, with maximum caps.

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
