overview
CORE SERVICE

Smart Contract Development

Secure, gas-optimized smart contracts built to your exact specifications.

We architect and deploy production-ready smart contracts that form the immutable logic layer of your Web3 application. Our development process is built on security-first principles and delivers contracts that are audit-ready from day one.

  • Custom Logic: Tailored Solidity/Rust contracts for DeFi, NFTs, DAOs, and enterprise use cases.
  • Security & Audits: Development with OpenZeppelin standards, followed by third-party audit coordination.
  • Gas Optimization: Every line of code is reviewed for efficiency, reducing user transaction costs by up to 40%.
  • Full Lifecycle: From specification and development to deployment, verification, and ongoing maintenance.

We deliver contracts you can stake your business on. Our code has secured over $500M+ in on-chain value for clients.

Core Capabilities of Our Notification Engine

Our infrastructure delivers precise, actionable alerts for multi-chain asset movements, enabling proactive portfolio management and risk mitigation.

01

Multi-Chain & Cross-Chain Monitoring

Track wallet balances and transaction activity across Ethereum, Solana, Polygon, Arbitrum, and 15+ other EVM & non-EVM chains from a single API endpoint. We handle the complexity of chain-specific RPC nodes and indexing.

02

Granular Alert Configuration

Define precise triggers for balance changes, including threshold-based alerts (e.g., >$1k), percentage changes, specific token movements, or interactions with known DeFi protocols. Filter noise to receive only relevant notifications.

Technical and Commercial FAQs

Answers to common questions about our development process, security, and commercial terms for the Multi-Chain Portfolio Balance Change Notifier service.

A standard Multi-Chain Portfolio Notifier for 3-5 blockchains with core alerting features is typically delivered in 3-5 weeks. This includes architecture, smart contract development, backend indexing, frontend dashboard, and integration testing. Complex requirements like custom on-chain event triggers or support for 10+ chains can extend the timeline, which we scope and agree upon before project kickoff.
