Business Outcomes for Your Treasury Operations
Move beyond basic multi-sig wallets. Our Account Abstraction Session Key Management delivers measurable improvements in security, operational speed, and cost control for institutional treasury workflows.
01
Eliminate Transaction Friction
Replace multi-sig approval delays with pre-authorized session keys for routine operations. Enable your treasury team to execute high-frequency tasks like payroll, vendor payments, and staking rewards without waiting for executive sign-offs.

Infrastructure Comparison
Session Key Management vs. Traditional Multi-Sig
A technical and operational comparison between modern session key management for account abstraction and legacy multi-signature wallet solutions.
| Feature | Traditional Multi-Sig | Chainscore Session Keys |
|---|---|---|
User Experience | Manual approval for every transaction | Pre-authorized sessions for seamless interaction |
Gas Efficiency | High (multiple signatures per tx) | Optimized (single signature for session) |
Security Model | M-of-N signature quorum | Time/scope-limited sessions + optional multi-sig |
Developer Overhead | High (custom logic, key management) | Low (SDK integration, managed infrastructure) |
Time to Implement | 8-16 weeks | 2-4 weeks |
Typical Use Case | Treasury management, DAO voting | Gaming, DeFi, Social dApps, Subscriptions |
Recovery Options | Complex (social recovery or new wallet) | Flexible (session revocation, social recovery) |
Infrastructure Cost (Annual) | $50K-$100K+ (dev time, audits) | $25K-$60K (managed service) |
Audit & Compliance | Your responsibility | Pre-audited modules + ongoing security |
