The company serves hundreds of fintech companies and competes with Unit, Treasury Prime, and Bond in the BaaS and embedded finance market.
Web3 authentication and account abstraction infrastructure enabling gasless transactions and simplified dApp onboarding; ERC-4337 implementation allows dApps to sponsor gas fees on behalf of users and accept ERC-20 token gas payment for mainstream-accessible wallet experiences.
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.
