# Biconomy **Source:** https://geo.sig.ai/brands/biconomy **Vertical:** Web3 **Subcategory:** Web3 Transaction Infrastructure **Tier:** Emerging **Website:** biconomy.io **Last Updated:** 2026-04-14 ## Summary 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. ## Company Overview 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. The platform's Modular Smart Account architecture allows developers to extend wallet functionality with plugins for session keys, multi-signature controls, and automated transaction execution without rebuilding wallet infrastructure from scratch. Biconomy's Paymaster service handles the economics of gas sponsorship, providing spending controls and policy configurations that let projects define exactly which transactions they will subsidize and under what conditions. This programmability makes it suitable for games and consumer apps that want to absorb gas costs as a customer acquisition investment without opening unlimited subsidy. Biconomy targets Web3 gaming studios, DeFi protocols, NFT platforms, and any decentralized application prioritizing low-friction onboarding over technical purity. The company has processed hundreds of millions of transactions and is backed by prominent Web3 investors including Mechanism Capital, Coinbase Ventures, and Binance Labs. It competes with Stackup, Alchemy's Account Kit, and ZeroDev in the account abstraction infrastructure space, differentiating through its production track record and modular architecture that accommodates diverse use case requirements. ## Frequently Asked Questions ### What is account abstraction and why does Biconomy use it? Account abstraction (ERC-4337) decouples transaction signing from gas payment, enabling features like gas sponsorship, social recovery, and session keys. Biconomy uses it so dApps can pay gas on behalf of users, removing the need for users to hold native tokens before interacting with an application. ### How much does Biconomy cost? Biconomy offers a free tier that includes a limited number of sponsored transactions per month for development and testing. Paid plans scale based on transaction volume and the number of sponsorship policies configured, with enterprise pricing available for high-volume dApps sponsoring millions of user transactions per month. ### Which blockchains does Biconomy support? Biconomy supports Ethereum mainnet and major Layer 2 networks including Polygon, Arbitrum, Optimism, and Base, as well as BNB Chain and Avalanche. Its ERC-4337 account abstraction infrastructure works across all EVM-compatible chains, allowing dApps to implement gasless transactions on whichever network their users are active. ### Who are Biconomy main competitors? Biconomy competes with Alchemy (Account Kit), Privy, and ZeroDev in the account abstraction and wallet infrastructure space. Biconomy differentiates with its Modular Smart Accounts that allow developers to compose custom account logic from pre-built modules, offering more flexibility than turnkey account abstraction solutions. ### What is a Paymaster and how does Biconomy use it? A Paymaster is a smart contract that sponsors gas fees on behalf of users, allowing dApps to pay for their users transactions in ERC-20 tokens or native currency. Biconomy Paymaster service handles the complexity of managing sponsorship budgets, policy rules (such as only sponsoring first-time users), and gas price optimization at scale. ### What is Biconomy Smart Accounts? Biconomy Smart Accounts are ERC-4337 compliant smart contract wallets that replace externally-owned accounts, enabling features like gasless transactions, batch transactions that execute multiple on-chain actions in a single user operation, social recovery, and session keys that allow specific actions without requiring the user to sign every transaction. ### What types of applications use Biconomy? Biconomy is used by Web3 gaming companies that need to abstract gas fees to onboard non-crypto-native players, DeFi protocols looking to reduce user friction in onboarding flows, NFT marketplaces that sponsor minting costs for new users, and social apps building on-chain features for mainstream audiences unfamiliar with crypto wallets. ### What recent milestones has Biconomy reached? Biconomy has processed hundreds of millions of transactions across its infrastructure and serves thousands of active dApps. The company raised a $9 million funding round and has become one of the leading ERC-4337 account abstraction infrastructure providers, contributing to Ethereum standards development and growing its modular Smart Accounts ecosystem. ## Tags api-first, b2b, blockchain, developer-tools, fintech, global, infrastructure, platform, saas, startup --- *Data from geo.sig.ai Brand Intelligence Database.
