Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that power your Web3 product. Our development process ensures security-first design, gas optimization, and compliance with standards like ERC-20, ERC-721, and ERC-1155.
OpenZeppelin libraries and Solidity 0.8+ best practices.Reduce your time-to-market with a 2-4 week MVP delivery for standard token or NFT contracts.
Our engineers specialize in complex logic for DeFi, gaming, and enterprise applications, delivering contracts with 99.9% uptime SLAs and comprehensive documentation for your team.
Our defense-in-depth approach combines on-chain, off-chain, and behavioral analysis to ensure only legitimate, high-quality nodes join your network, eliminating fake or malicious actors before they can cause harm.
We verify wallet history, transaction volume, and asset holdings directly on-chain to establish economic identity and stake. This prevents Sybil attacks from empty wallets and ensures participants have skin in the game.
Optional, enterprise-grade identity verification for permissioned networks or regulated environments. Integrates with leading providers for legal entity checks and AML compliance.
Continuous monitoring of node performance, uptime, and historical contributions. We build a dynamic reputation score to identify and de-prioritize unreliable or malicious actors over time.
Validates the physical and network integrity of node infrastructure. We check for dedicated hardware, geographic distribution, and resistance to common attack vectors like DDoS.
The final gate is governed by your network's existing validators or a decentralized council. Our system provides verified data, but the community holds ultimate onboarding authority.
Our node onboarding framework delivers measurable security and operational advantages, directly impacting your network's integrity and your bottom line.
Implement a multi-layered identity verification framework using zero-knowledge proofs and on-chain reputation scoring to eliminate fake nodes. This reduces the attack surface for 51% attacks and transaction censorship by over 95%.
Automate node vetting and reputation management, eliminating manual review overhead. Our system cuts the cost of node lifecycle management by up to 70% compared to traditional KYC/AML processes.
Deploy a production-ready, audited sybil-resistance layer in under 4 weeks. Our modular SDKs and pre-built attestation adapters accelerate integration with your existing node client.
Build with compliance-by-design using privacy-preserving proofs. Our framework provides verifiable audit trails for node operator due diligence, aligning with evolving FATF Travel Rule and MiCA requirements.
Ensure high-quality node participation through stake-weighted reputation. This leads to higher block proposal success rates, reduced latency, and more reliable data availability for your dApps.
Our system is protocol-agnostic, supporting Ethereum, Cosmos, Polkadot, and Solana Virtual Machine chains. Modular design allows easy integration of new attestation methods (e.g., World ID, Gitcoin Passport) as the landscape evolves.

A structured, four-phase approach to deliver a production-ready, sybil-resistant node onboarding system, minimizing your team's integration overhead and technical risk.
We analyze your network's specific trust model and threat vectors to design a custom sybil-resistance strategy. This includes selecting the optimal proof-of-personhood mechanism (e.g., Gitcoin Passport, Worldcoin, BrightID) and defining node reputation parameters.
Our engineers build the core on-chain logic for permissioned node registration, stake management, and reputation scoring using audited OpenZeppelin patterns. All contracts undergo internal security review before deployment.
We deploy a secure, scalable off-chain verification service that interfaces with your chosen identity providers. This includes building a robust REST/GraphQL API for your dApp to query node status and submit verification requests.
We manage the deployment to your specified testnet and mainnet environments, configure real-time monitoring dashboards (Grafana/Prometheus), and provide comprehensive documentation for your team to operate the system independently.
Common questions from CTOs and technical founders evaluating our node onboarding service. Get specific answers on timelines, security, and integration.
For a standard sybil-resistant node network with 50-100 nodes, we deliver a production-ready system in 3-5 weeks. This includes 1 week for design & threat modeling, 2-3 weeks for core development and integration, and 1 week for internal testing and client handoff. Complex deployments with custom consensus or multi-chain support may extend to 6-8 weeks. We provide a detailed project plan with weekly milestones upon engagement.
