Account Abstraction Vault-Wallet Integration
Smart Contract Development
Secure, audited smart contracts built to your exact specifications.
- Full-Stack Expertise:
Solidity/Rustdevelopment for EVM, Solana, and other L1/L2 networks. - Security-First: Contracts built with
OpenZeppelinpatterns and undergo internal review before formal audit. - Gas Optimization: Every line is written for minimum transaction cost and maximum efficiency.
We don't just write code; we deliver the secure, on-chain foundation your product needs to launch with confidence.
Core Technical Capabilities We Deliver
We architect and implement secure, scalable Account Abstraction vault-wallet systems that reduce development time and operational overhead for your team.
Custom Smart Account Development
We build ERC-4337-compliant smart accounts with modular features like social recovery, session keys, and multi-signature logic, enabling seamless user onboarding and enhanced security.
Paymaster & Gas Abstraction
Implement sponsor transaction and gasless onboarding flows. We design paymaster strategies for user acquisition and retention, handling complex gas sponsorship logic on your behalf.
Secure Vault Architecture
Design and deploy non-custodial, multi-signature vaults with granular access controls, time-locks, and transaction policies tailored for institutional or DAO treasury management.
Bundler Integration & Optimization
Integrate and optimize with high-performance bundlers (e.g., Stackup, Alchemy) to ensure reliable UserOperation submission, monitoring, and competitive fee estimation across networks.
Cross-Chain AA Wallet Systems
Build Account Abstraction solutions that operate across EVM and non-EVM chains using CCIP, LayerZero, or Wormhole, providing a unified wallet experience for your users.
Security Audits & Formal Verification
Our development includes rigorous internal audits, adherence to OpenZeppelin standards, and preparation for external audits by firms like Trail of Bits or Quantstamp to ensure contract safety.
Business Outcomes for Your Product
Our Account Abstraction Vault-Wallet Integration is engineered to deliver measurable improvements in user experience, security, and operational efficiency. Here's what you can expect.
Seamless User Onboarding
Eliminate seed phrase friction with social logins (Google, Apple) and email-based account recovery. Reduce user drop-off by up to 70% and acquire non-crypto-native users.
Enterprise-Grade Security & Compliance
Implement multi-signature policies, transaction limits, and role-based access control (RBAC) directly in smart accounts. Enforce KYC/AML checks at the wallet level for regulated DeFi.
Gasless Transaction Experience
Sponsor user gas fees via paymasters or abstract them entirely. Enable one-click batch transactions (e.g., swap + stake) to simplify complex DeFi interactions.
Accelerated Time-to-Market
Leverage our pre-audited, modular smart account infrastructure (ERC-4337) and SDKs. Deploy a production-ready, custom vault-wallet system in weeks, not months.
Reduced Operational Overhead
Automate treasury management with programmable spending rules and automated yield strategies. Cut manual intervention for routine transactions by over 90%.
Enhanced Developer Velocity
Integrate with our TypeScript/React SDK and comprehensive APIs. Build custom logic for session keys, subscription payments, and cross-chain actions without low-level protocol code.

Our Development & Integration Process
A structured, security-first approach to integrating Account Abstraction vaults, designed to deliver production-ready infrastructure with minimal disruption to your core product.
Architecture & Smart Contract Design
We architect your vault-wallet system using battle-tested patterns like ERC-4337 and ERC-6900. Deliverables include modular smart accounts, custom validation logic, and gas-efficient bundler integration.
Security Audit & Formal Verification
Every contract undergoes rigorous analysis. We integrate automated testing (Foundry/Slither) with manual review by our in-house security team before recommending third-party audits from firms like CertiK or Spearbit.
SDK & Frontend Integration
We provide a tailored TypeScript/React SDK to seamlessly embed AA vault features—social logins, batch transactions, gas sponsorship—into your existing dApp interface within days, not weeks.
Relayer & Bundler Infrastructure
We deploy and manage high-availability bundler nodes and paymaster services with 99.9% uptime SLA, handling user operation pooling, gas estimation, and transaction sponsorship.
Testing & Go-Live
Comprehensive staging on testnets (Sepolia, Amoy) with simulated load and attack vectors. We manage the mainnet deployment process, including contract verification and initial monitoring setup.
Monitoring & 24/7 Support
Post-launch, we provide real-time dashboards for vault activity, gas spending, and security alerts. Our team offers prioritized support with defined SLAs for incident response and upgrades.
Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic and audited for enterprise deployment.
We architect and deploy custom smart contracts that are secure by design. Every contract is built with Solidity 0.8+, follows OpenZeppelin standards, and undergoes rigorous internal audits before delivery. We focus on gas efficiency, upgradability patterns, and comprehensive test coverage exceeding 95%.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with advanced features like vesting, minting controls, and multi-chain compatibility. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms, and yield aggregators with battle-tested security patterns.
- Enterprise Logic: Multi-signature wallets, DAO governance modules, supply chain tracking, and custom business logic for real-world asset tokenization.
We deliver a fully documented, deployable package in 2-4 weeks, including audit reports and a deployment roadmap for mainnet launch.
Frequently Asked Questions
Get clear, technical answers to common questions about integrating smart contract wallets with institutional-grade vaults.
A standard integration, connecting a custom ERC-4337 smart account to a custody solution like Fireblocks or Copper, takes 2-4 weeks from kickoff to mainnet deployment. Complex multi-signature setups or novel recovery mechanisms can extend this to 6-8 weeks. We follow a phased delivery model with weekly demos.
