On-Chain Reputation Gated Access Development

We engineer dynamic NFT membership and subscription systems where access is programmatically determined by a user's verifiable on-chain history, such as transaction volume, governance participation, or asset holdings.

overview
FOUNDATION

Blockchain Infrastructure

Reliable, scalable node infrastructure for production-grade Web3 applications.

We provide fully managed, multi-chain node infrastructure with 99.9% uptime SLAs. Deploy dedicated nodes on Ethereum, Solana, Polygon, and other leading L1/L2 networks in minutes, not weeks.

  • Dedicated RPC endpoints with high throughput and low latency.
  • Real-time data indexing and historical archive access.
  • Automated failover and geo-distributed architecture for resilience.

Focus on building your dApp. We handle the complex, resource-intensive infrastructure layer.

Our infrastructure is built for scale, supporting everything from high-frequency DeFi protocols to NFT marketplaces with millions of users. We ensure sub-second response times and eliminate the operational overhead of self-hosting.

Core Capabilities of Our Reputation Gating Systems

We architect and deploy secure, modular reputation gating systems that integrate seamlessly with your existing infrastructure, enabling you to launch permissioned DeFi, DAOs, or NFT experiences in weeks, not months.

01

Multi-Protocol Reputation Aggregation

We build systems that aggregate on-chain reputation from sources like POAP, Galxe, Gitcoin Passport, and custom DAO voting history into a unified, verifiable score. This provides a holistic view of user identity and contribution.

Protocols Supported
< 100ms

02

Gas-Optimized Access Control

Our custom-built gating contracts use efficient storage patterns and signature verification to minimize gas costs for end-users. We implement standards like ERC-721 and ERC-1155 for NFT-gated access with sub-50k gas checkpoints.

Modular Rule Engine & SDK

A flexible, off-chain rule engine allows product teams to define complex gating logic (e.g., "Holder of X NFT AND score > Y") without contract redeploys. Includes a frontend SDK for easy integration.
