StarkNet Cairo ZK-Rollup Cash-Out System

Gas-optimized, audited smart contracts written in Cairo 1.0 for secure asset bridging, custody, and settlement logic. Built with OpenZeppelin security patterns and formal verification principles.

Seamless integration with StarkNet's sequencer for transaction batching and the SHARP prover for generating validity proofs. Ensures L1 finality with cryptographic security and minimal latency.

Dedicated, load-balanced RPC endpoints and a robust REST/WebSocket API for transaction submission, status polling, and real-time balance monitoring. Includes automatic failover.

Built-in transaction monitoring for AML/CFT screening, real-time alerting, and comprehensive audit logs. Facilitates regulatory reporting for fiat gateway partners.

Middleware that intelligently routes cash-out requests to optimal banking/payment partners based on liquidity, fees, and jurisdiction, maximizing success rates and minimizing cost.

Infrastructure-as-Code (Terraform) for StarkNet nodes and auxiliary services. CI/CD pipelines for contract deployment and system updates with zero-downtime blue/green deployments.

Move user funds from L2 to L1 in under 1 second with zero-confirmation finality, powered by StarkNet's validity proofs. Eliminates multi-day withdrawal delays that degrade user experience.

Cairo smart contracts built with OpenZeppelin libraries and audited by leading security firms. Multi-sig governance and formal verification ensure your bridge and treasury logic is bulletproof.

Batch thousands of user cash-out requests into a single L1 transaction. Drastically reduce per-user withdrawal fees, making micro-transactions economically viable and improving your platform's margins.

Architected with built-in transaction monitoring, source-of-funds tracing, and configurable withdrawal limits. Simplifies integration with KYC/AML providers and meets evolving financial regulations.

Process 10,000+ cash-out transactions per second (TPS) without congestion. Our system scales horizontally with your user base, maintaining performance during market volatility and peak demand.

Leverage our battle-tested, modular Cairo codebase and deployment pipelines. Go from specification to mainnet launch in weeks, not months, accelerating your product roadmap.

We define the system architecture, token flow, and Cairo smart contract interfaces. This includes finalizing L1/L2 bridging logic, fee models, and compliance requirements for your specific use case.

Our experts write, test, and optimize Cairo 1.0 contracts for the rollup's core logic (withdrawals, fee management, state updates). We implement security patterns and gas optimization from day one.

We deploy the audited system to StarkNet testnet (Goerli). We integrate with your front-end, run end-to-end user simulations, and provide a full staging environment for your team to validate.

We manage the mainnet deployment on StarkNet, configure monitoring (transaction success rates, bridge latency), and provide 24/7 incident response support for the first 30 days post-launch.

Complete technical documentation, operational runbooks, and source code handover. We ensure your team is fully equipped to maintain and scale the system independently.
