overview
CORE SERVICE

Smart Contract Development

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

We deliver audit-ready smart contracts on day one. Our development process, built on Solidity 0.8+ and OpenZeppelin standards, ensures your core logic is secure and gas-optimized from the start.

Deploy with confidence, backed by formal verification and battle-tested patterns.

Our development scope includes:

  • Custom Tokenomics & DeFi Logic: ERC-20, ERC-721, staking, yield, and governance systems.
  • Cross-Chain & Layer 2: Native development for EVM, Solana, and rollups like Arbitrum and Optimism.
  • Full Testing Suite: Comprehensive unit and integration tests with >95% coverage.
  • Gas Optimization: Code reviews focused on reducing user transaction costs by 15-40%.

We provide a complete technical package: final source code, deployment scripts, and documentation. This turns your concept into a live, maintainable product in as little as 2-4 weeks for an MVP.

ENTERPRISE-GRADE INFRASTRUCTURE

Core Capabilities of Our Notification APIs

Our APIs deliver mission-critical alerts with the reliability and precision required for production blockchain applications. We handle the infrastructure so your team can focus on building.

01

Real-Time Event Detection

Monitor on-chain events across 30+ EVM and non-EVM chains with sub-second latency. We parse contract logs and transaction receipts to trigger alerts for specific function calls, token transfers, and protocol interactions.

PREDICTABLE, TRANSPARENT DELIVERY

Our Delivery Process: From Specification to Production

We deliver production-ready notification systems on a fixed timeline. Our phased approach ensures alignment, security, and rapid deployment for your Web3 product.

01

Phase 1: Discovery & Specification

We conduct a technical deep-dive to define your exact notification triggers (on-chain events, wallet activity, price thresholds) and delivery channels (email, SMS, Telegram, Discord).

Deliverable: A signed technical specification document detailing scope, APIs, and success metrics.
