Our Migration Service Capabilities
We execute a structured, low-risk migration from legacy prediction platforms (like Augur v1, Polymarket v1) to modern, scalable architectures. Our process is designed to preserve user assets, minimize downtime, and unlock new capabilities.
01
Architecture & Smart Contract Migration
We port your core prediction market logic to optimized Solidity 0.8+ contracts. This includes migrating markets, user positions, and liquidity pools with cryptographic proof of integrity, ensuring no loss of funds or state.

STRUCTURED APPROACH
Our 4-Phase Migration Process
A proven, risk-mitigated methodology to migrate your legacy prediction platform to a modern, scalable Web3 architecture without disrupting your user base.
01
Phase 1: Discovery & Architecture
We conduct a full audit of your existing platform, including smart contract logic, oracle dependencies, and user state. We then design a target architecture on EVM-compatible L2s (Arbitrum, Optimism) or app-chains, ensuring scalability and cost efficiency.

Technical Migration Process
Legacy Prediction Market Migration FAQs
Answers to the most common technical and commercial questions about migrating your legacy prediction platform to a modern, scalable Web3 stack.
A complete migration from a legacy platform (e.g., Augur v1, Gnosis Conditional Tokens) to a modern stack typically takes 4-8 weeks. This includes 1-2 weeks for architecture review and planning, 2-4 weeks for core smart contract development and testing, and 1-2 weeks for integration, final audits, and deployment. For platforms with complex oracle integrations or custom market types, timelines may extend to 10-12 weeks.
