Secure, audited smart contracts built to your exact specifications.
We architect and deploy production-grade smart contracts for tokens, DeFi protocols, and NFT projects. Our process ensures security-first development with formal verification and comprehensive audits before mainnet deployment.
Deploy with confidence on
EVMorSolanain 2-4 weeks.
ERC-20, ERC-721, or complex DeFi primitives like AMMs and lending pools.We deliver production-ready cross-chain NFT bridges with enterprise-grade security, performance, and reliability, enabling your project to scale across ecosystems.
Custom bridge logic deployed on all major EVM and non-EVM chains (Ethereum, Polygon, Arbitrum, Solana, Aptos). We handle chain-specific optimizations and gas-efficient message passing.
Implement ZK-SNARK/STARK circuits for trust-minimized state verification. Our bridges use cryptographic proofs, not multisig assumptions, for maximum security and censorship resistance.
Managed, auto-scaling relayers with 99.9% uptime SLA. We provide monitoring, failover, and automatic gas price optimization to ensure seamless cross-chain transactions.
Non-custodial, audited smart contract vaults for locking and minting NFTs. Built with OpenZeppelin standards and formal verification to protect millions in digital assets.
Dynamic fee calculation and subsidization models. We design systems that minimize end-user costs while ensuring relayers are economically incentivized.
Complete SDKs, APIs, and dashboard for monitoring bridge health, transaction status, and volume analytics. Seamless integration with existing wallets and marketplaces.
Our cross-chain bridge development delivers measurable value, from expanding your market to securing your assets. Here’s what you can expect.
Instantly access liquidity and users across Ethereum, Solana, Polygon, and other major chains. Unlock new revenue streams without fragmenting your community.
Enable your NFTs to be used in DeFi protocols, gaming ecosystems, and marketplaces on any connected chain, increasing holder engagement and perceived value.
Bridge contracts undergo formal verification and audits by leading firms like CertiK. We implement multi-signature controls and continuous monitoring to protect assets in transit.
We manage the bridge infrastructure, including relayers, indexers, and monitoring, with a 99.9% uptime SLA. Your team focuses on core product development.
Leverage our battle-tested bridge architecture and deployment templates. Go from concept to a production-ready, mainnet bridge in as little as 4-6 weeks.
Our modular design allows for seamless integration of new chains (Aptos, Sui) and standards (ERC-6551). Avoid costly rewrites as the ecosystem evolves.
A detailed comparison of the key technical, operational, and financial factors between developing a custom cross-chain NFT bridge with Chainscore and relying on a generic third-party solution.
| Key Factor | Generic Third-Party Bridge | Chainscore Custom Bridge |
|---|---|---|
Time to Integration | 1-2 weeks | 4-8 weeks |
Custom Logic & Features | None (one-size-fits-all) | Full customizability |
Branding & User Experience | Vendor-branded UI/UX | Fully white-labeled |
Security Model & Audits | Shared risk (public audits) | Dedicated, audited codebase |
Protocol & Chain Support | Limited to vendor roadmap | Tailored to your roadmap |
Fee Structure & Economics | Vendor takes a cut | You control 100% of fees |
Data Sovereignty & Control | Vendor-controlled | You own the infrastructure |
Ongoing Maintenance | Vendor's responsibility | Optional SLA with our team |
Total Cost of Ownership (Year 1) | $0-$50K (usage fees) | $80K-$200K (custom build + optional SLA) |
Long-term Strategic Value | Low (vendor lock-in) | High (owned IP, competitive moat) |
From initial architecture to mainnet deployment, our battle-tested process ensures your cross-chain NFT bridge is secure, scalable, and ready for production. We deliver predictable timelines and enterprise-grade reliability.
We design your bridge's core architecture, selecting optimal protocols (LayerZero, Axelar, Wormhole) and token standards (ERC-721, ERC-1155) for your specific use case. This includes defining secure message passing, fee models, and upgradeability patterns.
Our engineers write production-grade Solidity/Vyper contracts for both source and destination chains. We implement gas-optimized mint/burn/lock mechanisms, admin controls, and pausable functions using OpenZeppelin libraries.
Every line of code undergoes rigorous review. We conduct internal audits, automated analysis (Slither, MythX), and partner with top firms like CertiK for final certification before any deployment, ensuring fund safety.
We build and deploy secure, high-availability relayers or integrate with decentralized oracle networks to validate and forward cross-chain messages, guaranteeing transaction finality and preventing double-spends.
We deploy to testnets (Goerli, Sepolia) for exhaustive testing, followed by a phased mainnet rollout with circuit breakers. We provide full deployment scripts and multisig wallet configuration for team control.
Post-launch, we implement real-time monitoring for bridge health, failed transactions, and security events. Our team is on-call with defined SLAs for incident response and protocol upgrades.

Get clear answers on timelines, security, costs, and technical details for your NFT bridge project.
A standard, audited cross-chain NFT bridge from design to mainnet deployment typically takes 4-6 weeks. This includes protocol design, smart contract development, security audits, frontend integration, and deployment. For more complex requirements like custom minting logic or multi-chain support, timelines extend to 8-12 weeks. We provide a detailed project plan within the first week of engagement.
