About
Biconomy is a Web3 infrastructure platform focused on making decentralized applications usable by mainstream audiences who are not familiar with cryptocurrency gas mechanics. Its core product implements account abstraction via ERC-4337, allowing dApp developers to sponsor gas fees on behalf of users, accept gas payment in ERC-20 tokens instead of native currency, and batch multiple on-chain transactions into a single user action. These capabilities transform the user experience from one requiring native token balances and technical awareness into something closer to a conventional web application workflow.
