overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
We deliver a complete development lifecycle: from initial design to mainnet deployment, with a focus on reducing time-to-market by 40% for new protocols.
- Token Standards: Custom
ERC-20,ERC-721, andERC-1155with advanced features like vesting, staking, and governance. - DeFi & dApps: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators, and cross-chain bridges.
- Security First: Every contract undergoes internal review and is structured for seamless integration with top audit firms like
CertiKandTrail of Bits.

PROVEN PROCESS
Our Migration Methodology
A structured, four-phase approach designed to de-risk your transition, ensure data integrity, and deliver a production-ready prediction market on modern infrastructure.
01
Discovery & Architecture Audit
We conduct a deep technical assessment of your legacy system, mapping contracts, oracle dependencies, and liquidity flows to design a future-proof architecture on EVM or Solana.

Business Outcomes of a Successful Migration
Migrating your prediction market to a modern blockchain stack delivers measurable improvements in performance, security, and market reach. Here’s what you can expect.
01
Radically Lower Transaction Costs
Replace high API and settlement fees with predictable, sub-dollar on-chain transaction costs. Our migration architecture leverages Layer 2 solutions like Arbitrum or Optimism to reduce user fees by 90-99% compared to legacy payment processors.

Technical Migration Guide
Prediction Market Migration FAQs
Common questions from CTOs and technical leads planning to migrate legacy prediction markets to modern, scalable blockchain infrastructure.
A standard migration from a centralized or outdated on-chain system takes 3-6 weeks from kickoff to mainnet deployment. This includes 1 week for audit and planning, 2-3 weeks for core development and testing, and 1-2 weeks for security audits and final deployment. Complex migrations with custom oracle integrations or novel dispute mechanisms may extend to 8-10 weeks. We provide a detailed project plan within the first 3 days of engagement.
