As a developer building Web3 applications, you’re likely encountering significant user experience barriers that limit your user base to crypto-natives and create support overhead.

​
Common Web3 UX Challenges

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

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

​
How Smart Accounts Transform Your Application

Smart Accounts replace traditional EOAs with programmable accounts, enabling powerful features:

​
Simplified Onboarding

Passkey Authentication

WebAuthn eliminates seed phrases

Social Recovery

Account recovery through guardian contracts

Session Keys

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

Enable gasless user experiences via paymasters

Batch Operations

Reduce total gas costs by bundling multiple actions

​
Enhanced Automation

Delegated Execution

Bot and AI agent integrations with granular permissions

Scheduled Transactions

Execute based on time or condition triggers

Cross-Chain Sequencing

Orchestrate multi-chain operations with single approval

​
Biconomy Nexus Advantages

​
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

​
Implementation Benefits

​
For Your Users

  • Onboard with email/social login instead of managing seed phrases
  • Execute transactions without holding ETH
  • Recover accounts through social recovery mechanisms
  • Approve once for complex multi-step operations

​
For Your Application

  • Increase conversion rates by removing wallet friction
  • Reduce support tickets related to key management
  • Enable advanced features like subscription payments and automated strategies
  • Maintain compatibility with existing Web3 infrastructure

​
For Your Development Team

  • Ship faster with production-ready smart contracts
  • Add features through modules without redeploying core contracts
  • Leverage extensive testing and security audits
  • Build on industry standards ensuring long-term compatibility

​
