Token Allowance & Approval Change Monitors

Build a security-first alerting layer for your wallet or dApp. We develop real-time monitors that track ERC-20/ERC-721 token approvals, notifying users of new, modified, or suspicious allowances to prevent exploits.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that power your token, DeFi protocol, or NFT platform. Our development process is built on security-first principles using Solidity 0.8+, OpenZeppelin libraries, and comprehensive audit trails to mitigate risk.

Deliver a market-ready product in 4-6 weeks, from initial spec to audited mainnet deployment.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 contracts with advanced features like vesting, minting controls, and governance hooks.
  • DeFi & DEX Logic: Automated Market Makers (AMMs), liquidity pools, staking mechanisms, and yield optimizers.
  • Security & Compliance: Formal verification, third-party audit coordination, and gas optimization for cost-efficient operations.

Our Delivery Methodology

We deliver production-ready monitoring infrastructure through a structured, transparent process designed for technical leaders who need reliability, not surprises.

01

Discovery & Architecture Review

We conduct a deep-dive technical session to map your token ecosystem, identify critical approval patterns, and define monitoring thresholds. This ensures our solution aligns with your specific security posture and compliance requirements.
