Account Abstraction Bundled Transaction Security

We design and implement secure, user-signed transaction bundles using ERC-4337 and smart contract wallets. Our solutions ensure atomic execution to eliminate sandwich attacks and failed-arbitrage losses for institutional DeFi users.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts that form the secure, automated backbone of your application. Our team specializes in Solidity 0.8+ and Vyper, implementing battle-tested patterns from OpenZeppelin and rigorous internal audits to eliminate vulnerabilities before deployment.

Deliver a fully audited, gas-optimized contract suite in 4-6 weeks, ready for mainnet launch.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 with advanced features like vesting, staking, and governance.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators with sub-second finality.
  • Enterprise Logic: Multi-signature wallets, supply chain tracking, and automated escrow for real-world asset (RWA) tokenization.
  • Security First: Every contract undergoes static analysis, manual review, and formal verification to meet institutional-grade security standards.

Business Outcomes for Your Protocol

Our bundled transaction security for account abstraction delivers measurable improvements in user experience, operational cost, and protocol safety.

01

Eliminate Gas Complexity

We implement gas sponsorship and batch transactions so users never need native tokens for fees, removing the #1 onboarding friction. This directly increases user acquisition and retention.

02

Guaranteed Transaction Atomicity

Our bundled execution ensures multi-step operations (e.g., swap + bridge + stake) succeed or fail as a single unit. This prevents partial failures and protects user funds, building critical trust.

FOUNDATION

Blockchain Infrastructure

Enterprise-grade node infrastructure with 99.9% uptime SLA and real-time monitoring.

We operate and maintain dedicated, high-performance nodes across major protocols like Ethereum, Solana, Polygon, and Arbitrum. This eliminates the operational overhead of running your own infrastructure, ensuring high availability, low latency, and predictable costs.

Focus on building your application, not managing servers. We handle the complexity so you can scale.

  • Guaranteed Performance: 99.9% uptime SLA with sub-second response times for RPC calls.
  • Full Protocol Coverage: Access to historical data, event logs, and archive nodes.
  • Real-Time Health Dashboards: Monitor latency, error rates, and sync status via our portal or API.
  • Security & Compliance: Enterprise-grade security, DDoS protection, and SOC 2 compliance.

Frequently Asked Questions

Get clear answers on how we secure your bundled transactions and abstracted accounts.

We implement a multi-layered defense: custom mempool privacy via Flashbots Protect, simulation-based validation before submission, and time-lock encryption for sensitive payloads. Our bundlers use private transaction relays and commit-reveal schemes to minimize exposure, typically reducing MEV extraction risk by over 95% compared to public mempools.
