FULL-STACK INFRASTRUCTURE
Custom Blockchain Development
End-to-end blockchain solutions from protocol design to production deployment.
- Custom Consensus & EVM Compatibility: Build on
Substrate,Cosmos SDK, or custom EVM rollups (Arbitrum Nitro,OP Stack). - Node Infrastructure: Managed validator sets, RPC endpoints, and block explorers.
- Cross-Chain Bridges: Secure, audited bridges for asset and data transfer between networks.
- Governance Modules: On-chain DAO tooling for proposal voting and treasury management.
We handle the entire stack so your team can focus on application logic, reducing time-to-market from months to as little as 8 weeks for a custom chain MVP.

Frequently Asked Questions
Get answers to common technical and commercial questions about implementing our Account Abstraction Wallet SDK.
For a standard integration with a new or existing Web3 application, typical implementation takes 2-3 weeks. This includes setup, custom feature development (like social login or gas sponsorship), and full testing. Complex multi-chain deployments or custom smart account logic may extend this to 4-6 weeks.
