Solana news: Phantom Wallet Switches Prediction Market Infrastructure to World on Solana
Phantom Wallet Adopts World for Prediction Markets
Phantom, a leading crypto wallet, has updated its prediction market infrastructure by replacing Kalshi with World for positions opened from 1 June. This move transitions new prediction markets to a noncustodial protocol, routing orders directly to liquidity providers on the Solana blockchain.
How the Change Affects Users
For new positions, payouts are now automatically redeemed when an event concludes, eliminating the need for a separate settlement trade. This streamlines the user experience and leverages Solana's fast and low-cost transaction capabilities.
Positions opened before 1 June remain linked to Kalshi via DFlow. Users with these contracts must manually exchange expired outcome tokens for the stablecoin initially used, with final payouts subject to market conditions and settlement data.
Resolution and Oracle Updates
The transition also introduces changes to how market outcomes are determined. While older markets rely on Kalshi data processed through DFlow, new positions may use oracles such as Chainlink. Phantom has cautioned that delays, incorrect data, or indexing issues could still impact market resolution and potentially result in financial losses.
Noncustodial and Compliance Features
Phantom emphasises that it does not take custody of user funds, act as a counterparty, or maintain a house edge. All transactions occur directly between users, with each market following its own resolution rules. Updated disclosures now prohibit trading contracts when users possess material nonpublic information or have a direct conflict of interest.
Why This Matters for the UK Solana Community
This update is relevant to UK users and developers interested in decentralised prediction markets and Solana-based trading. The shift to a noncustodial protocol and use of on-chain oracles aligns with growing UK regulatory interest in transparency and user protection within the crypto sector.
