overview
FULL-STACK INFRASTRUCTURE

Custom Blockchain Development

End-to-end blockchain infrastructure development for FinTechs and Web3 startups.

We architect and deploy production-grade blockchain networks tailored to your specific use case—whether it's a private consortium chain, a custom L2, or a dedicated appchain. Our full-stack approach ensures seamless integration with your existing systems.

  • Core Protocol Development: Custom Solidity/Rust smart contracts, token standards (ERC-20, ERC-721), and consensus mechanisms.
  • Node & Validator Infrastructure: Managed Geth, Besu, or Cosmos SDK nodes with 99.9% uptime SLAs.
  • Security-First Builds: All code undergoes rigorous audits following OpenZeppelin standards and formal verification practices.

Deliver a fully audited, scalable network in 6-8 weeks, not months. We handle the complex infrastructure so you can focus on product and growth.

Core Technical Capabilities We Deliver

We architect and deploy secure, scalable Account Abstraction (AA) stacks that meet the stringent requirements of institutional payment systems. Our solutions are built on verifiable engineering excellence and audited security patterns.

01

Custom Smart Account Development

Tailored ERC-4337-compliant smart contract accounts with multi-signature, session keys, and role-based access controls. We implement gas sponsorship, batched transactions, and social recovery to streamline institutional workflows.

Frequently Asked Questions

Common questions from CTOs and technical leaders evaluating our institutional-grade account abstraction development services.

From initial design to mainnet deployment, a standard implementation takes 4-6 weeks. This includes smart contract development, integration with your existing treasury or ERP systems, and comprehensive security audits. For more complex requirements like multi-chain deployments or custom signature schemes, timelines are scoped individually, typically ranging from 8-12 weeks.
