FULL-STACK ENGINEERING
Custom Blockchain Development
End-to-end blockchain solutions built for scale, security, and speed-to-market.
From smart contract suites to custom consensus layers, we build the infrastructure your application needs to succeed.
- Core Protocol & L1/L2 Development: Custom blockchains, rollups (Optimistic, ZK), and sidechains using
Substrate,Cosmos SDK, orArbitrum Nitro. - Smart Contract Ecosystems: Secure, gas-optimized contracts for DeFi, NFTs, and DAOs, built with
Solidity 0.8+andRust. - Node Infrastructure & Tooling: High-availability validator nodes, indexers, explorers, and custom RPC endpoints.
- Integration & Upgrades: Seamless integration with existing systems and protocol upgrade management.

PROVEN FRAMEWORK
Our Offensive Security Testing Methodology
Our battle-tested, multi-layered approach simulates real-world attacks to uncover critical vulnerabilities before they can be exploited, ensuring your payment network's integrity and compliance.
01
Comprehensive Threat Modeling
We begin by mapping your entire payment architecture—nodes, APIs, wallets, smart contracts—to identify high-value attack surfaces and define realistic adversary profiles.

Frequently Asked Questions on Institutional Payment Network Testing
Get clear answers on our methodology, timeline, and security guarantees for blockchain payment network penetration testing.
A comprehensive penetration test for an institutional payment network typically takes 2-4 weeks. This includes a 1-week scoping and planning phase, 2 weeks of active testing (smart contracts, APIs, infrastructure), and 1 week for report compilation and debrief. For complex, multi-chain systems, the timeline may extend to 5-6 weeks.
