BUILT FOR NFT LENDING
Core Smart Account Capabilities We Deliver
We architect and deploy the foundational smart account infrastructure that powers seamless, secure, and scalable NFT loan experiences. Each capability is designed to reduce technical debt and accelerate your product launch.
01
Gas Abstraction & Sponsorship
Implement gasless transactions for your users. We set up flexible sponsorship models—paymaster integrations, batch transactions, and fee delegation—so borrowers never need native ETH for gas, removing a major UX friction point.

02
Multi-Asset Collateral Management
Enable users to collateralize diverse NFT collections (ERC-721, ERC-1155) within a single account. Our smart contracts handle secure vaulting, valuation oracles, and automated liquidation triggers for complex multi-collection portfolios.

Session Keys & Automated Actions
Build "set-and-forget" loan management. We implement secure session keys that allow automated, pre-approved actions like repayment top-ups or collateral swaps, ensuring loans stay healthy without constant user intervention.

Social Recovery & Secure Ownership
Move beyond seed phrase anxiety. We deploy customizable recovery modules using guardians (EOAs, other smart accounts, or trusted entities) so users can securely regain access, drastically reducing support overhead and lost funds.

Batch Operations & Composability
Bundle multiple loan actions into one transaction. Our smart accounts enable atomic operations—like depositing collateral, drawing debt, and swapping assets—reducing gas costs by up to 40% and creating a smoother user journey.

Business Outcomes for Your Lending Platform
Account Abstraction transforms NFT lending from a technical challenge into a competitive advantage. We deliver concrete outcomes that drive user adoption and platform growth.
01
Frictionless Onboarding
Eliminate seed phrase complexity with social logins and email/password recovery. New users can deposit collateral and take their first loan in under 60 seconds, directly from their mobile device.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
We deliver custom smart contracts that are secure, gas-optimized, and ready for mainnet deployment. Our development process is built on Solidity 0.8+ with OpenZeppelin security patterns and includes comprehensive unit testing.
- Token Standards:
ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi Protocols: DEXs, lending/borrowing platforms, staking, and yield aggregators.
- Governance Systems: DAO tooling, multi-sig wallets, and voting mechanisms.
- Security First: Every contract undergoes peer review and is prepared for third-party audits.
We focus on business logic first, ensuring your contract architecture aligns with your product goals and regulatory considerations.
Typical deliverables include a fully documented codebase, a deployment script, and a 2-week MVP timeline for standard token or staking contracts.

Frequently Asked Questions
Get clear answers on how we build secure, user-friendly NFT lending experiences with ERC-4337 and smart accounts.
A standard implementation, including smart account integration, gas sponsorship, and a custom transaction flow, takes 2-4 weeks. Complex features like multi-chain support or novel recovery mechanisms can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones after the initial technical discovery.
