Enterprise Blockchain Bridge Migration Services

End-to-end service to securely migrate assets and application logic from your private or permissioned blockchain to a public ecosystem via a custom-built, compliant bridge.
Chainscore © 2026
overview
FULL-STACK ENGINEERING

Custom Blockchain Development

Build production-grade blockchain networks and applications with expert engineering and proven architecture.

We architect and deploy custom blockchains, sidechains, and layer-2 solutions tailored to your specific throughput, privacy, and consensus requirements. Our team delivers complete, audited systems—from the core protocol layer to the application interface—ensuring security and performance from day one.

  • Private & Consortium Chains: Permissioned networks with Hyperledger Besu, Corda, or custom Geth forks.
  • High-Performance L2s: Optimistic or ZK rollups on Ethereum, Arbitrum Orbit, or Polygon CDK.
  • App-Specific Chains: Cosmos SDK and Substrate development for sovereign ecosystems.
  • Full Lifecycle Support: Genesis to mainnet, including validator set management and upgrade governance.

We focus on architectural correctness and operational readiness, not just proof-of-concepts. Every deployment includes a production runbook, monitoring dashboard, and disaster recovery plan.

Our development process is built for enterprise outcomes: 4-6 week delivery for core MVP features, adherence to security standards like NIST and ISO 27001, and 99.9% uptime SLAs for validator services. We become your technical co-pilot, ensuring your chain scales with your business.
