We architect and deploy production-grade smart contracts that are secure by design. Every contract undergoes rigorous internal audits and is built using battle-tested patterns from OpenZeppelin and Solmate.
Bitcoin-to-Sovereign Rollup Bridge Development
Smart Contract Development
Secure, audited smart contracts built to your exact specifications and deployed on-chain.
From tokenomics to complex DeFi logic, we translate your business requirements into immutable, gas-efficient code.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155contracts with advanced features like vesting, staking, and governance. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators, and derivative instruments.
- Enterprise Logic: Multi-signature wallets, supply chain tracking, and verifiable credential systems.
- Full Lifecycle Support: Development, testing (
Hardhat/Foundry), deployment, and post-launch monitoring.
Core Bridge Architecture & Capabilities
Our Bitcoin-to-Sovereign Rollup bridge is built on battle-tested, modular components designed for security, performance, and seamless integration. We deliver production-ready infrastructure, not just prototypes.
Decentralized Custody & Multi-Sig Security
Secure asset custody via a modular multi-signature wallet architecture (e.g., 3-of-5). All signing logic is implemented in audited smart contracts, eliminating single points of failure and ensuring institutional-grade security for locked Bitcoin.
Optimistic Fraud Proof System
A secure challenge-response layer that allows any watcher to dispute invalid state transitions on the rollup. This ensures the canonical state is always correct without requiring constant validator consensus, balancing security with efficiency.
Light Client Relayer Network
A decentralized network of relayers submits compact Bitcoin block headers to the rollup contract. This enables the bridge to autonomously verify Bitcoin transaction inclusion proofs, ensuring trust-minimized interoperability.
Modular Messaging & Data Availability
A flexible cross-chain messaging layer (CCIP-compatible) for arbitrary data transfer alongside asset movements. Paired with robust data availability solutions to guarantee transaction data is published and accessible for fraud proofs.
Gas-Optimized Settlement Contracts
Core bridge logic is implemented in highly optimized Solidity (0.8.x+) using established patterns from OpenZeppelin. We focus on minimizing gas costs for end-users during mint/burn operations and proof verification.
Proven Deployment Framework
We provide a complete deployment pipeline with automated testing, staging environments on testnets, and mainnet launch support. Includes monitoring dashboards for bridge health, liquidity, and security events.
Why Build a Bitcoin-Secured Sovereign Rollup?
Move beyond theoretical benefits. A Bitcoin-secured sovereign rollup delivers concrete, measurable advantages for your application's security, economics, and long-term viability.
Unmatched Security Foundation
Leverage Bitcoin's battle-tested Proof-of-Work, the most secure and decentralized network, as your settlement and data availability layer. This eliminates the security overhead of bootstrapping a new validator set.
Radical Cost Efficiency
Decouple execution costs from Bitcoin's base layer fees. Your rollup handles high-throughput transactions at minimal cost, while leveraging Bitcoin's security for finality, avoiding the high operational expense of standalone chains.
Full Sovereignty & Flexibility
Retain complete control over your stack—from virtual machine (EVM, SVM, Cairo) to governance and upgrade paths. You are not bound by another L1's roadmap or social consensus.
Native Bitcoin Liquidity Access
Build applications that can natively custody, transfer, and utilize Bitcoin (BTC) as the primary asset, unlocking deep liquidity and user familiarity without wrapped asset intermediaries.
Accelerated Time-to-Market
Deploy a production-ready, Bitcoin-secured rollup in weeks, not years. We provide the battle-tested infrastructure, security templates, and deployment automation so you can focus on application logic.
Build vs. Buy: Sovereign Rollup Bridge Development
A detailed comparison of the time, cost, and risk involved in developing a secure Bitcoin-to-sovereign rollup bridge in-house versus partnering with Chainscore Labs.
| Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K |
Security & Audit Overhead | High (unaudited risk) | Pre-audited, battle-tested modules |
Core Team Expertise Required | Specialized Bitcoin & Rollup engineers | Our team provides full-stack expertise |
Ongoing Maintenance & Updates | Dedicated internal team (2-3 FTE) | Optional SLA with 24/7 monitoring |
Protocol Upgrade Risk | Your responsibility to track & implement | We manage upgrades and forward compatibility |
Time to First Value (MVP) | Q3-Q4 | Q1 |
Guaranteed Uptime SLA | Self-managed (no SLA) | 99.9% uptime SLA available |
Our Development & Delivery Process
A structured, transparent approach to building your Bitcoin-to-Sovereign Rollup bridge, designed for technical founders who need predictable timelines and enterprise-grade security.
Architecture & Protocol Design
We define the optimal bridge architecture (light client, multi-sig, or hybrid) and select the sovereign rollup stack (e.g., OP Stack, Arbitrum Orbit) based on your security and throughput requirements.
Smart Contract & Circuit Development
Development of verifier contracts for Bitcoin SPV proofs and zero-knowledge circuits for state validation, using Solidity 0.8+ and Circom/Noir, following OpenZeppelin security patterns.
Security Audits & Formal Verification
Comprehensive security review by our in-house experts, followed by a formal audit from a top-tier firm like Trail of Bits or Quantstamp, with full remediation support.
Testnet Deployment & Staging
Full deployment to Bitcoin testnet (Signet/Testnet3) and your chosen rollup test environment, including rigorous load testing and integration with your dApp frontend.
Mainnet Launch & Monitoring
Managed mainnet deployment with phased roll-out strategies. We provide 24/7 monitoring, alerting, and dashboards for bridge health, liquidity, and security events.
Documentation & Handover
Complete technical documentation, operational runbooks, and developer guides delivered. We ensure your team is fully equipped to maintain and iterate on the bridge.
Bitcoin Bridge Development: Key Questions
Answers to the most common questions from CTOs and founders evaluating a custom Bitcoin-to-sovereign rollup bridge.
A standard Bitcoin-to-sovereign rollup bridge MVP is typically deployed in 2-4 weeks. This includes the core bridge smart contracts, a basic relayer, and integration with your rollup's execution environment. Complex features like multi-signature governance, advanced monitoring, or custom economic models can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones after the initial technical scoping.
