Secure, production-ready smart contracts built by Web3 experts.
We architect and deploy custom smart contracts that form the foundation of your dApp. Our development process ensures security-first design, gas optimization, and audit readiness from day one.
Solidity 0.8+ with OpenZeppelin libraries for battle-tested security patterns.Deploy a secure, audited MVP in as little as 2 weeks, not months.
Our iterative development cycle delivers production-ready contracts for:
Our policy-based authorization engine provides the granular, real-time access control required for secure and compliant Web3 applications. We deliver the infrastructure, so your team can focus on building features.
Evaluate complex authorization rules in <50ms, enabling instant on-chain and off-chain access decisions for DeFi swaps, NFT mints, and governance actions without compromising user experience.
Define access using RBAC and ABAC models. Enforce rules based on user roles, token holdings, transaction history, or custom on-chain data to create sophisticated gating logic for your dApp features.
Every authorization decision is immutably logged with full context—user, resource, policy, and outcome. Generate compliance reports instantly for financial regulators or internal security audits.
Deploy consistent authorization logic across EVM chains (Ethereum, Polygon, Arbitrum) and beyond. Manage user permissions seamlessly as they interact with assets on different networks.
Built on globally distributed nodes with automatic failover. We guarantee 99.9% uptime SLA for policy evaluation, ensuring your application's access control is never a single point of failure.
Dynamic policy-based authorization isn't just a security feature—it's a strategic enabler. We deliver measurable business results by embedding fine-grained access control directly into your application logic.
Deploy new features and manage user permissions in real-time without smart contract redeploys. Our SDKs and APIs let your product team iterate on access rules in hours, not weeks.
Eliminate manual admin key management and centralized bottlenecks. Automated, auditable policy enforcement reduces human error and the overhead of manual compliance checks.
Build products where users control their access levels and data. Granular, transparent permission models increase platform credibility and user engagement in DeFi and SocialFi applications.
Create sophisticated subscription models, gated content, and premium feature tiers. Our policy engine enables complex revenue logic that executes autonomously and transparently.
Go beyond simple ownership checks. Implement role-based (RBAC) and attribute-based (ABAC) access control with multi-sig enforcement, time locks, and spending limits baked into the policy.
A technical comparison of authorization models, highlighting the operational and security advantages of Chainscore's dynamic policy engine over static, code-based systems.
| Authorization Factor | Traditional (Static RBAC/ABAC) | Chainscore Dynamic Policy Engine |
|---|---|---|
Policy Update Time | Weeks (requires code deploys) | Minutes (via admin dashboard or API) |
Attack Surface | High (complex, immutable logic) | Low (centralized, auditable policy layer) |
Multi-Chain Support | Custom per chain (high dev cost) | Native (single policy, any EVM chain) |
Real-Time Risk Adaptation | ||
Audit Trail & Compliance | Manual logging required | Automatic, immutable logs on-chain |
Developer Onboarding | Months to understand custom code | Days with our SDK & documentation |
Time to Implement | 3-6 months | 2-4 weeks |
Total Cost of Ownership (Year 1) | $150K+ (dev + audit + maint) | $50K - $100K (managed service) |
We deliver production-ready policy engines in weeks, not months, through a structured, security-first approach designed for Web3's unique demands.
We co-design your authorization logic, mapping complex business rules to granular, enforceable policies using standards like OPA (Open Policy Agent) and Zanzibar. This ensures your system scales without sacrificing security.
Our engineers embed policy decision points directly into your Solidity/Vyper contracts. We implement gas-optimized checks for on-chain actions and secure off-chain attestation patterns for complex logic.
We deploy and configure a high-availability policy engine (e.g., OPA, Styra DAS) in your cloud or on-premise environment. Includes load balancing, monitoring, and integration with your existing auth stack (Auth0, Cognito).
Every policy and integration undergoes rigorous review. We conduct internal audits focusing on logic flaws and privilege escalation, following best practices from OWASP and leading Web3 security firms.
We build a comprehensive test suite including unit tests, integration tests against a forked mainnet, and policy simulation tools to validate decisions under millions of potential user-state combinations.
We provide complete documentation, operational runbooks, and integrate real-time monitoring dashboards (Grafana, Datadog) for policy decision logs, performance metrics, and security alerts.

Dynamic policy-based authorization is a security model where access control decisions are made in real-time based on a set of programmable rules (policies) that can evaluate user attributes, transaction context, and on-chain state. Unlike static role-based systems, it's essential for Web3 because it enables granular, context-aware permissions for DeFi operations, DAO governance, and NFT gating—securing assets while maintaining user flexibility. We've implemented these systems for protocols managing over $500M in TVL.
