Spending Limit & Policy Engine Development

We build secure, granular spending rules and transaction policies into smart contract wallets for corporate treasuries, DAOs, and family finance, enabling programmable control over funds.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by experts for your Web3 application.

We architect and deploy audit-ready smart contracts on EVM-compatible chains like Ethereum, Polygon, and Arbitrum. Our development process is built on OpenZeppelin standards and rigorous internal review to mitigate risk from day one.

Deliver a secure, functional foundation in weeks, not months.

  • Custom Logic: Tailored Solidity 0.8+ contracts for DeFi, NFTs, DAOs, and enterprise use cases.
  • Security-First: Proactive vulnerability analysis and integration with tools like Slither and MythX.
  • Full Lifecycle: From initial spec and development through to deployment, verification, and ongoing upgrade management.

We provide clear technical documentation and a comprehensive audit report for your team and stakeholders. Partner with us to build with confidence and accelerate your time-to-market.

Frequently Asked Questions

Get clear answers on our development process, security, and timelines for implementing custom spending controls.

A standard spending limit and policy engine deployment takes 2-4 weeks from kickoff to mainnet launch. This includes requirements analysis, smart contract development, integration with your existing wallet/dApp, and security review. Complex multi-chain deployments or advanced rule logic can extend this to 6-8 weeks.
