CORE SERVICE
Custom Smart Contract Development
Secure, audited smart contracts built for your specific business logic and deployed to production.
- End-to-End Development: From specification and
Solidity/Rustcoding to testing and mainnet deployment. - Security-First: Built with
OpenZeppelinstandards and subjected to rigorous internal + third-party audits. - Protocol Specialization:
ERC-20,ERC-721, staking systems, custom oracles, and bespoke DeFi logic.
We deliver a fully functional, secure smart contract system in as little as 2-4 weeks, giving you a trusted foundation to build upon.

Technical & Commercial FAQs
Common Questions on Prediction Data Indexing
Get specific answers on timelines, costs, and technical capabilities for our cross-chain prediction data indexing service.
Standard deployments for a single-chain indexer with 5-10 core events take 2-3 weeks from kickoff to production. Multi-chain deployments (e.g., Ethereum + Polygon + Arbitrum) typically require 3-5 weeks, factoring in chain-specific RPC optimization and testing. We provide a detailed sprint plan within the first 48 hours of engagement.
