Biconomy's Paymaster API is a service that allows developers to either sponsor transaction gas fees for users or enable users to pay gas fees with their preferred ERC20 token. With the entire service managed by us, developers can focus on their core business without concerns about gas spends in native tokens or token swapping to recover fees.

Pricing

Our pricing is tailored according to the Paymaster service you choose, ensuring alignment with your specific needs.

Token Paymaster

Allow your users to pay gas fees with any token (ERC20 standard). We divide the number of tokens supported into two baskets:

• Alpha Basket: Includes stablecoins, wrapped ETH, BTC, and your native token at a 7% premium.
• Beta Basket: All other tokens, are charged at a 12% premium to cover price risks.

Sponsorship Paymaster

Sponsor your users' gas fees by depositing native tokens into the Paymaster contract. For example on the BSC Chain, BNB tokens are required. There is currently no markup on the gas tank; how much you sponsor for your users is how much you pay
