PROVEN METHODOLOGY
Our Migration Framework
A structured, four-phase approach to migrate your legacy game economy to blockchain with minimal disruption and maximum player retention. We handle the technical complexity so you can focus on your community.
01
Architecture & Tokenomics Design
We design a custom blockchain architecture and tokenomics model that mirrors your existing in-game economy. This includes mapping legacy currencies to fungible tokens (ERC-20) and items to NFTs (ERC-721/1155) while preserving player equity.

Build In-House vs. Partner with Chainscore
A clear comparison of the effort, risk, and cost involved in migrating your legacy game to blockchain.
| Key Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Live Ops | 6-12+ months | 8-16 weeks |
Initial Development Cost | $250K - $750K+ | $80K - $200K |
Core Team Required | 5-10+ engineers | Your product lead + our team |
Smart Contract Security | High risk (unaudited, custom) | Enterprise-grade (audited, battle-tested patterns) |
Blockchain Expertise Gap | Significant (steep learning curve) | Zero (our core competency) |
Ongoing Maintenance & Updates | Full internal team burden | Optional SLA with 24/7 monitoring |
Integration Complexity | High (custom wallet, RPC, indexers) | Managed (pre-built SDKs & APIs) |
Time-to-Market Risk | Very High (delays are likely) | Low (fixed-scope, predictable delivery) |

STRUCTURED APPROACH
Our 4-Phase Migration Process
A proven, methodical framework to migrate your legacy game to blockchain with zero downtime, full asset security, and predictable outcomes.
01
Phase 1: Discovery & Architecture
We conduct a deep technical audit of your existing game, mapping assets, economies, and user flows. The output is a detailed migration blueprint, including tokenomics design (ERC-20/721/1155), L1/L2 selection, and a phased go-live strategy.
