We architect, develop, and audit custom Solidity and Rust smart contracts that form the immutable business logic of your dApp. Our process delivers production-ready code in weeks, not months.
API Gateway Token Gating
Smart Contract Development
Secure, gas-optimized smart contracts built to your exact specifications.
We build contracts that are secure by design, not by audit.
- Custom Tokenomics & DeFi Logic:
ERC-20,ERC-721, staking systems, liquidity pools, and governance modules. - Security-First Development: Adherence to OpenZeppelin standards, formal verification, and pre-audit code reviews.
- Gas Optimization: Every line of code is written for minimum execution cost, saving your users money.
- Full Lifecycle Support: From ideation and development to deployment on
EVM/SVMchains and post-launch maintenance.
Core Technical Capabilities We Deliver
Our token-gated API gateway provides the foundational infrastructure for secure, scalable, and compliant Web3 integrations. We deliver production-ready solutions that abstract away blockchain complexity.
Real-Time Token & NFT Validation
On-chain verification of ERC-20, ERC-721, and ERC-1155 holdings with configurable thresholds. Our system checks wallet balances and verifies ownership in < 100ms, ensuring instant access control.
Granular Role-Based Access Control (RBAC)
Define complex permission logic based on token type, quantity, and metadata. Create tiered access levels (e.g., Bronze, Silver, Gold) and manage them dynamically via smart contract events.
High-Performance Caching & Rate Limiting
Optimized caching layer for RPC calls to reduce latency and prevent rate limiting from node providers. Configurable request throttling per user tier to protect your backend infrastructure.
Comprehensive Audit Logging & Analytics
Full visibility into all authentication attempts, API usage, and token verification events. Export logs to your SIEM and monitor key metrics like unique active wallets and API call volume.
Custom Webhook & Event-Driven Integrations
Receive real-time webhooks for key on-chain events (mints, transfers, staking) to trigger backend workflows. Seamlessly integrate with your existing CRM, CMS, or internal systems.
Business Outcomes for Your Product
Our API Gateway for Token Gating delivers measurable infrastructure improvements, accelerating your product's time-to-market while ensuring enterprise-grade security and scalability.
Accelerated Development
Integrate token-gated APIs in days, not months. We provide production-ready SDKs for Node.js, Python, and Go, with comprehensive documentation and developer support.
Enterprise Security & Compliance
Built with zero-trust principles. All access policies are enforced at the edge, with audit logs for every request. SOC 2 Type II compliant infrastructure.
Unified Multi-Chain Access
Gate API access based on tokens from Ethereum, Solana, Polygon, and other EVM chains from a single endpoint. Simplify your architecture.
Predictable Performance at Scale
Guaranteed sub-100ms latency for token validation with 99.9% uptime SLA. Auto-scales to handle traffic spikes from zero to millions of requests.
Granular Access Control
Define precise access rules: minimum token balance, specific NFT traits, token age, or custom on-chain logic. No-code rule builder included.
Reduced Operational Overhead
Eliminate the cost and complexity of managing your own RPC nodes, indexers, and security layers. We handle infrastructure, monitoring, and updates.

Our Development & Integration Process
A structured, four-phase approach designed for technical leaders. We deliver production-ready API gateways with clear milestones, transparent communication, and guaranteed SLAs.
Architecture & Design Review
We analyze your existing stack and token logic to design a scalable, secure gateway architecture. This includes threat modeling, gas optimization strategies, and finalizing integration points.
Smart Contract Development
Our engineers write, test, and deploy the core token-gating logic using Solidity 0.8+ and OpenZeppelin libraries. Includes comprehensive unit and integration testing on testnets.
API Gateway Integration
We build and deploy the secure REST/GraphQL API layer that interfaces with your contracts. Features include rate limiting, request signing, and real-time access control checks.
Deployment & Security Audit
Final deployment to mainnet with a comprehensive security review. We provide audit reports, monitoring dashboards, and documentation for your engineering team.
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
We architect and deploy custom smart contracts for DeFi, NFTs, and enterprise applications. Our team delivers audit-ready code using Solidity 0.8+ and OpenZeppelin standards, ensuring security and gas efficiency from day one.
- End-to-End Development: From specification and
Hardhat/Foundrytesting to mainnet deployment and verification. - Security-First: Rigorous internal audits, formal verification, and adherence to OWASP Top 10 for Web3.
- Protocol Integration: Native support for
ERC-20,ERC-721,ERC-1155, and custom standards likeERC-4626for vaults.
Deliver a secure, functional MVP in as little as 2-4 weeks, with guaranteed 99.9% uptime SLA for live contracts.
Frequently Asked Questions
Get clear, specific answers to common questions about implementing token-gated API access with Chainscore.
A standard deployment of our API Gateway with token gating takes 2-4 weeks from kickoff to production. This includes integration with your existing API, smart contract deployment (if needed), and full testing. Complex multi-chain or custom rule logic can extend this timeline, which we scope during the initial consultation.
