overview
FULL-STACK INFRASTRUCTURE

Custom Blockchain Development

End-to-end blockchain solutions from protocol design to mainnet deployment.

We architect and build production-grade blockchain networks tailored to your specific use case. From private consortium chains to public L2 rollups, we deliver complete infrastructure with 99.9% uptime SLAs and enterprise-grade security.

  • Custom L1/L2 Development: Build on Substrate, Cosmos SDK, or Optimism Stack.
  • Smart Contract Ecosystems: Deploy secure Solidity, Rust, or Move contracts with formal verification.
  • Node & Validator Operations: Managed infrastructure with monitoring, alerts, and governance tooling.
  • Cross-Chain Bridges & Interop: Secure asset and data transfer between networks.

Deploy a fully functional testnet in under 4 weeks, with a clear path to mainnet launch and ongoing protocol maintenance.

TAILORED SECURITY FRAMEWORKS

What We Deliver

We build and implement custom security rule-sets designed specifically for your application chain's architecture and threat model, moving beyond generic best practices.

01

Custom Security Policy Engine

A dedicated, on-chain or off-chain rule engine that enforces your application's specific business logic and security policies, preventing invalid state transitions and unauthorized actions at the protocol level.

< 100ms
Rule Evaluation
02

Transaction Lifecycle Hardening

Comprehensive rule-sets for mempool validation, block construction, and execution—mitigating front-running, sandwich attacks, and MEV extraction specific to your dApp's transaction flow.

Threat Detection
03

Consensus & Validator Security

Specialized slashing conditions, delegation policies, and governance rules for your PoS or PoA chain to ensure validator integrity and protect against long-range attacks and cartel formation.

Cross-Chain Bridge Safeguards

If your AppChain interacts with external networks, we implement rigorous validation rules for message attestation, rate limiting, and fraud-proof windows to eliminate bridge exploit vectors.

Upgrade & Governance Controls

Secure, multi-layered governance rule-sets with timelocks, veto powers, and stakeholder voting weights to manage protocol upgrades and parameter changes without introducing centralization risks.

Why Generic Tools Fall Short for AppChains

Generic Scanner vs. Chainscore Custom Rule-Sets

Public scanners use one-size-fits-all rules for public L1/L2 chains. AppChains require security logic tailored to your custom VM, consensus, and economic model. This table compares the capabilities.

PROVEN METHODOLOGY

Our Development & Integration Process

A structured, security-first approach to implementing custom AppChain rule-sets, designed for rapid deployment and long-term resilience.

01

Threat Modeling & Requirements Analysis

We conduct a collaborative workshop to map your AppChain's attack surface, define security objectives, and establish clear, measurable requirements for your rule-set.

Frequently Asked Questions

Get clear answers on our methodology, timeline, and security guarantees for custom AppChain rule-sets.

An AppChain-specific security rule-set is a custom configuration of automated security monitors and alerts built for your unique blockchain application. Off-the-shelf solutions miss chain-specific exploits. We build rules that understand your smart contract logic, tokenomics, and governance model to detect anomalies like flash loan attacks, validator misbehavior, or economic exploits before they impact users. This proactive layer is essential for any AppChain handling significant value or user assets.
