Biconomy Nexus - The Ultimate Smart Account Solution
Smart Accounts Overview
As a developer building Web3 applications, you're likely encountering significant user experience barriers:
- Onboarding friction: Private key management and seed phrases result in user drop-offs
- Gas token requirements: Users must hold native tokens (ETH/MATIC/etc) before interacting with your dApp
- Account recovery limitations: Lost private keys mean permanent loss of user accounts and assets
- Transaction complexity: Multi-step processes and cross-chain operations require multiple signatures
- Limited automation: EOAs cannot execute scheduled or conditional transactions
These constraints limit your user base to crypto-natives and create support overhead.
How Smart Accounts Transform Your Application
Smart Accounts replace traditional EOAs with programmable accounts, enabling:
Simplified Onboarding
- Passkey authentication via WebAuthn eliminates seed phrases
- Social recovery modules enable account recovery through guardian contracts
- Session keys allow pre-approved transactions without repeated signatures
Flexible Payment Options
- ERC-20 gas payments let users pay fees in USDC, USDT, or your native token
- Sponsored transactions via paymasters enable gasless user experiences
- Batch operations reduce total gas costs by bundling multiple actions
Enhanced Automation
- Delegated execution enables bot and AI agent integrations with granular permissions
- Scheduled transactions execute based on time or condition triggers
- Cross-chain sequencing orchestrates multi-chain operations with single approval
Biconomy Nexus - The Most Gas Efficient and Secure Smart Account
Performance & Cost Efficiency
- 25% lower gas costs compared to alternative implementations through optimized contract design
- Batched operations via ERC-7579 modules reduce transaction overhead
- Efficient calldata encoding minimizes L2 data availability costs
Composable Batching
Nexus is the only smart account solution on the market enabling composable batch execution. It allows developers to encode batch calls where the next instruction depends on the output of the previous one.
Production-Ready Architecture
- EIP-7702 compatibility ensures forward compatibility with Ethereum's account abstraction roadmap
- Modular design (ERC-7579) enables you to install third-party modules on user accounts
- Cross-chain support includes all major EVM networks with unified deployment addresses
Security & Reliability
- 92% DefiSafety score demonstrates adherence to security best practices
- Battle-tested contracts 2M+ smart accounts, $500M+ value processed without incidents
Developer Experience
- AbstractJS SDK provides type-safe interfaces for account interactions
- Pre-built modules for common features (recovery, spending limits, session keys)
- Standardized interfaces ensure compatibility with ecosystem tooling

Technical Architecture
Nexus implements a modular smart account system based on:
- Core Account: Minimal proxy implementation for gas efficiency
- Validation Modules: Support for ECDSA, passkeys, and custom authentication
- Execution Modules: Enable batching, automation, and cross-chain operations
- Fallback Handlers: Extend functionality for specific use cases
This architecture ensures optimal gas costs while maintaining upgradeability through the module system.
