We architect and deploy custom Solidity and Rust contracts for DeFi, NFTs, and enterprise applications. Our focus is on security-first development, utilizing battle-tested patterns from OpenZeppelin and rigorous internal audits to mitigate risk before deployment.
Cross-Chain NFT Bridge for Real-World Asset Tokenization
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
- From Concept to Mainnet: Full lifecycle support from design and
Truffle/Hardhattesting to deployment and verification. - Protocol Specialization: Expertise in
ERC-20,ERC-721,ERC-1155, and complex DeFi primitives like AMMs and lending vaults. - Guaranteed Quality: Deliverables include comprehensive test suites, deployment scripts, and technical documentation.
We don't just write code; we deliver audit-ready contracts that form the secure foundation of your on-chain product, reducing time-to-market and technical debt.
Architected for Compliance and Verifiable Provenance
Tokenizing real-world assets demands more than just a bridge; it requires a system designed for regulatory adherence and immutable audit trails. Our infrastructure ensures your assets move with legal certainty and transparent history.
Regulatory-Compliant Smart Contracts
Custom-built bridge logic with built-in compliance hooks for KYC/AML, accredited investor verification, and jurisdiction-specific transfer restrictions. Deploy with confidence for securities, real estate, and other regulated assets.
Immutable Provenance Ledger
Every cross-chain transfer generates a cryptographically-verified, on-chain record of custody, ownership history, and transaction metadata. Provides a single source of truth for auditors, regulators, and asset owners.
Institutional-Grade Custody Integration
Seamless API integration with leading institutional custodians (Fireblocks, Copper) and MPC wallets. Supports multi-signature governance and policy-based transaction signing for secure asset movement.
Automated Reporting & Monitoring
Real-time dashboards and automated report generation for regulatory filings (e.g., FATF Travel Rule), tax compliance (FIFO, cost-basis), and internal risk management. Export data in regulator-ready formats.
Business Outcomes for RWA Platforms and Marketplaces
Our cross-chain NFT bridge is engineered to deliver measurable business value, enabling platforms to scale, secure, and monetize tokenized real-world assets with institutional-grade infrastructure.
Expand Market Liquidity
Unlock capital across Ethereum, Polygon, and Solana ecosystems. Our bridge enables seamless asset transfers, increasing your pool of potential buyers and sellers to drive deeper liquidity and tighter spreads.
Accelerate Time-to-Market
Deploy a production-ready, audited bridge in weeks, not months. We provide a white-label solution with custom UI/UX integration, allowing you to focus on your core marketplace logic and go live faster.
Ensure Regulatory & Audit Compliance
Build trust with institutional partners. Our bridge architecture supports provenance tracking, on-chain compliance modules (like ERC-3643), and integrates with leading third-party audit trails for real-world asset verification.
Reduce Operational Complexity & Cost
Eliminate the engineering burden of maintaining multi-chain validators and relayers. We manage all bridge infrastructure with a 99.9% uptime SLA, predictable pricing, and 24/7 monitoring, turning a capital expense into a simple operational cost.
Enable New Revenue Streams
Monetize cross-chain activity with configurable bridge fees. Support fractionalized high-value assets (like real estate, art) by enabling micro-transactions on lower-fee chains, opening up new investor segments and fee models.
Future-Proof Asset Interoperability
Avoid vendor lock-in with our modular, upgradeable smart contract system. We design for the multi-chain future, ensuring your tokenized RWAs can move to new high-performance chains (like Arbitrum, zkSync) as they emerge.
Build vs. Buy: Why a Custom RWA Bridge is Essential
A detailed comparison of the total cost, risk, and timeline of developing a custom cross-chain NFT bridge for Real-World Assets (RWA) in-house versus partnering with Chainscore Labs.
| Critical Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Market | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $80K - $200K |
Security Audit & Compliance | High Risk (unaudited, custom code) | Pre-audited, battle-tested modules |
Ongoing Maintenance & DevOps | Requires dedicated 3-5 person team | Optional 24/7 SLA with monitoring |
Cross-Chain Protocol Expertise | Steep learning curve (ERC-5169, CCIP, LayerZero) | Deep expertise across all major protocols |
RWA-Specific Features (e.g., Legal Wrappers, KYC) | Custom integration required | Pre-built, configurable modules |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $120K - $300K |
Guaranteed Uptime SLA | Your responsibility (typically < 99%) | 99.9% Enterprise SLA |
Our Methodology for Compliant Bridge Architecture
We architect cross-chain NFT bridges for RWA tokenization with a security-first, compliance-by-design approach, ensuring institutional-grade reliability and regulatory adherence from day one.
Regulatory-First Design
We integrate compliance logic (e.g., OFAC screening, jurisdictional whitelists) directly into the bridge's smart contracts and relayers, automating adherence to global financial regulations for tokenized assets.
Multi-Layer Security Architecture
Our architecture employs a hybrid model: decentralized validator sets for consensus, MPC/TSS for key management, and fraud-proof systems like optimistic verification to secure asset custody and message passing.
Proven Interoperability Stack
We build with battle-tested protocols (Wormhole, Axelar, LayerZero) and custom light clients, ensuring seamless, low-latency communication between Ethereum, Polygon, Solana, and other target chains for RWAs.
Gas-Optimized & Scalable Relayers
We develop custom relayers with gas-efficient transaction bundling and fee abstraction, significantly reducing cross-chain transfer costs for end-users and ensuring scalability under high load.
End-to-End RWA Lifecycle Support
Our solution includes off-chain verifiers for physical asset attestation, NFT metadata standards for legal provenance, and integration hooks for custodians, KYC providers, and secondary markets.
Frequently Asked Questions on RWA NFT Bridges
Get clear answers on timelines, security, costs, and technical implementation for your Real-World Asset tokenization bridge.
A standard, production-ready cross-chain RWA NFT bridge deployment takes 4-8 weeks from kickoff to mainnet launch. This includes 1-2 weeks for architecture design and smart contract development, 2-3 weeks for rigorous security audits and testing, and 1-2 weeks for deployment and integration with your existing systems. Complex requirements like multi-chain support or custom compliance modules can extend this timeline.
