Trueo, an on-chain prediction market protocol launched on Base in March 2025, said on September 21, 2026, that it plans to migrate its primary deployment to Ethereum mainnet. The project said Ethereum better supports its goal of building a widely adopted, broadly integrated, permissionless, mostly immutable and credible platform, while Base served as an environment for early experimentation when Ethereum gas costs were higher. Existing Base markets will continue trading and remain accessible after migration, with the current resolution system applying to markets that expire after the move. Users were advised not to create additional Base markets expiring after January 31, 2027, and to create those markets on Ethereum instead. TYD will continue accruing yield. The migration's initial priorities are attracting liquidity in major market categories and releasing a next-generation oracle, which Trueo says will use evidence from legitimate data sources to improve dispute resolution. Ethereum co-founder Vitalik Buterin endorsed the project in a post on X, praising its focus on decentralization and ethical design. TRUE's market capitalization rose from about $1.7 million to more than $12 million after the endorsement. CoinGecko data put the token near $0.15, up 699% over 24 hours and nearly 750% over one week, though it remained almost 50% below its $0.26 all-time high from August 2025. The announcement came as Kalshi and Polymarket faced legal disputes over prediction-market activity and trading conditions across the sector remained uneven.
