PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to deliver a production-ready, privacy-focused transaction mixer. We handle the technical complexity so you can launch faster and with confidence.
01
Architecture & Protocol Design
We design a custom multi-sig mixer architecture based on your specific anonymity set requirements and target chain (EVM, Solana, etc.). This includes selecting and adapting proven cryptographic primitives like zk-SNARKs or ring signatures.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that are secure by design. Our development process includes formal verification, gas optimization, and comprehensive unit testing to ensure reliability from day one.
- Custom Logic: Build
ERC-20,ERC-721,ERC-1155, and bespoke token standards. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking systems.
- Security First: Adherence to OpenZeppelin patterns and multiple audit layers.
- Full Lifecycle: From initial spec to mainnet deployment and post-launch monitoring.
We deliver audited, gas-efficient contracts that power your product, not hold it back. Typical delivery for an MVP suite is 2-3 weeks.

Frequently Asked Questions
Get clear answers on how our custom multi-sig transaction mixer development works, from security to deployment.
From initial design to mainnet deployment, a standard privacy-focused multi-sig mixer takes 4-6 weeks. This includes 1 week for architecture and smart contract design, 2-3 weeks for development and internal testing, and 1-2 weeks for security audits and final deployment. Complex features like cross-chain support or custom governance can extend this timeline, which we scope and agree upon upfront.
