Trueo plans to move its main onchain prediction market from Base to Ethereum’s mainnet, a change the protocol says will place its long-term markets on a more permissionless and largely immutable base layer while preserving uninterrupted access to its existing application.
The protocol announced the migration on Monday and said its next priorities will be building liquidity in selected market categories and releasing an updated oracle system after the Ethereum deployment goes live. Vitalik Buterin acknowledged the planned move in a post on X following Trueo’s announcement.
Trueo launched on Base in March 2025, choosing the Ethereum Layer 2 network while mainnet transaction costs were higher. Its decision to return to Ethereum’s base layer reflects a different set of trade-offs: mainnet settlement can offer deeper integration with established onchain capital and infrastructure, though users may face higher transaction fees than on Base.
The migration also places the protocol’s governance and market-resolution ambitions more directly on Ethereum, where applications can rely on the network’s established settlement layer rather than a separate rollup environment. Trueo has framed that design choice around reducing dependence on any one operator or intermediary.
Existing Base markets will remain available
Trueo said its application will continue operating before and during the migration, with no planned change to its development roadmap. Existing markets on Base will not be closed simply because the main deployment is moving to Ethereum.
The protocol has asked users not to create new Base markets that expire after Jan. 31, 2027. Long-dated markets should instead be created on the Ethereum instance once it is live, according to Trueo’s guidance. Markets scheduled to expire before that date are unaffected.
Base markets that settle after the migration will remain accessible through Trueo’s official application. That approach avoids forcing users to abandon positions already opened on Base, while steering future long-term activity toward Ethereum mainnet.
Trueo’s native TRUE token will also remain central to the protocol after the move. Token holders will be able to migrate TRUE from Base to Ethereum, and the protocol said the migration window will remain open indefinitely. An open-ended bridge period could limit pressure on holders to act within a short deadline, though users would still need to use official migration tools carefully.
Oracle design moves to the center of the product
The mainnet move comes as Trueo focuses heavily on how prediction markets determine outcomes. A prediction market can attract trading volume only if participants believe settlement rules will be applied consistently, especially when an event’s real-world outcome and the wording of a market’s deadline do not align neatly.
Trueo said it is developing an oracle designed to process evidence from “virtually any legitimate data source” and deliver outcomes it describes as fair and accurate. An oracle is the mechanism that brings offchain information — such as corporate filings, election results, economic data, or sports scores — into a blockchain-based market for settlement.
The protocol said the new system is intended to be more impartial and credible than approaches used by other prediction-market platforms. Its stated goal is infrastructure that can reduce reliance on a single party to interpret evidence, decide which source controls, or resolve a disputed outcome.
That is a difficult promise to execute. Even markets with transparent smart contracts can produce controversy if the event language is vague, the acceptable evidence is unclear, or published records arrive after a stated cutoff. The quality of an oracle therefore depends not only on its technical design, but also on the market rules established before trading begins.
Polymarket lawsuit illustrates settlement disputes
A lawsuit involving rival prediction-market platform Polymarket has put those questions into sharper focus. In July, two traders sued the platform over a market asking whether Strategy would sell any of its Bitcoin by May 31. The plaintiffs held “Yes” shares.
Strategy confirmed that it sold 32 BTC between May 26 and May 31, according to the facts described in the lawsuit. Yet the market was resolved as “No” because the relevant filing was released on June 1, after the market’s deadline.
The plaintiffs alleged that Polymarket changed the market’s terms after settlement and argued that this conflicted with the platform’s commitment to rules-based outcomes. The dispute turns on a familiar prediction-market problem: whether a market should resolve based on when an event occurred or when supporting evidence became formally available.
Trueo has pointed to that type of disagreement as a reason to build a resolution process capable of handling evidence from multiple legitimate sources. A system that clearly defines the event, the cutoff time, accepted evidence and dispute procedure before a market opens would give traders a firmer basis for judging risk.
Ethereum mainnet will not by itself solve those governance questions. The migration instead gives Trueo a more established settlement environment as it tries to make oracle rules and market resolution the distinguishing features of its product. Its ability to attract liquidity will depend on whether users view those rules as clearer and more dependable than the systems already used by larger prediction-market platforms.
