overview
CORE SERVICE

Custom Smart Contract Development

Secure, production-ready smart contracts built by experts for DeFi, NFTs, and enterprise applications.

We architect and deploy audit-ready smart contracts that power your core business logic. Our development process ensures security-first design, gas optimization, and full test coverage before mainnet deployment.

From concept to mainnet in as little as 2-4 weeks.

Our development stack includes:

  • Solidity 0.8+ with OpenZeppelin standards
  • Foundry/Hardhat for testing and deployment
  • ERC-20, ERC-721, ERC-1155 and custom token standards
  • DeFi primitives like AMMs, lending pools, and staking contracts
  • Cross-chain logic for Layer 2 and multi-chain deployments

Deliverables you receive:

  • Production-ready source code with comprehensive documentation
  • Security audit report from our internal review process
  • Deployment scripts and configuration for testnet/mainnet
  • Post-launch support and upgrade path planning

TECHNICAL EXCELLENCE

Core Capabilities of Our Aggregation Service

We deliver a production-ready, secure, and scalable event aggregation layer for your Polkadot parachain, designed to accelerate development and enhance user experience.

01

Multi-Parachain Event Aggregation

Real-time, normalized event streams from multiple parachains (Acala, Moonbeam, Astar, etc.) into a single, unified API. Eliminates the complexity of managing individual RPC connections and block explorers.
