DELIVERABLES
Business Outcomes for Your DeFi Product
Our Account Abstraction development service delivers concrete, measurable improvements to your DeFi product's security, user experience, and operational efficiency.
01
Enhanced User Security & Onboarding
Replace seed phrases with familiar Web2 authentication (social logins, biometrics) and implement session keys for seamless, non-custodial transactions. Drastically reduces user friction and eliminates a primary vector for asset loss.

Frequently Asked Questions
Get clear answers about our development process, security, and timelines for implementing private, compliant DeFi with Account Abstraction.
We deliver a production-ready, audited protocol in 4-8 weeks from kickoff. This includes a 2-week design and architecture phase, 3-5 weeks of core development and integration (ERC-4337, privacy modules), and a final week for internal testing and deployment preparation. Complex multi-chain deployments or custom zero-knowledge circuits may extend this timeline, which we scope and agree upon upfront.
