DELIVERABLES & GUARANTEES
Business Outcomes for Your Product
Our StarkNet account abstraction services deliver measurable improvements to your product's performance, security, and user experience. We focus on concrete results, not just features.
01
Gasless User Onboarding
Eliminate the need for users to hold ETH for gas fees. We implement paymaster integrations and session keys to create a Web2-like sign-up flow, removing the primary barrier to entry.

CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built to your exact specifications.
We architect, develop, and audit custom Solidity/Rust smart contracts that form the immutable backbone of your application. Our focus is on security-first development and gas efficiency, ensuring your logic is both robust and cost-effective to execute.
- Full Lifecycle Development: From initial design and
OpenZeppelinintegration to deployment and verification onEVM/Solana/Starknet. - Comprehensive Audits: Internal reviews, formal verification with tools like
Slither/MythX, and preparation for third-party audits. - Production-Ready Code: Implementation of upgradeability patterns (
TransparentProxy,UUPS), pausable functions, and role-based access control.
Deliver a secure, auditable, and maintainable smart contract system in 2-4 weeks for a standard MVP.

Frequently Asked Questions
Get clear answers on our development process, timelines, security, and support for your StarkNet account abstraction project.
We follow a structured 4-phase methodology: 1. Discovery & Scoping (1 week): We analyze your requirements and define the smart account architecture (e.g., multisig, session keys, social recovery). 2. Development & Testing (2-4 weeks): Our team builds and rigorously tests the contracts using Cairo, our in-house testing framework, and tools like Protostar. 3. Audit & Deployment (1-2 weeks): Contracts undergo internal review and can be prepared for third-party audits. We handle deployment to StarkNet testnet/mainnet. 4. Handover & Support: We provide full documentation and 90 days of bug-fix support.
