Phantom has migrated the infrastructure supporting its cryptocurrency wallet prediction market, replacing its previous Calci-based system with World for positions opened from June 1st.
With this change, the new market will move to a non-custodial protocol that routes orders to liquidity providers on Solana. Payments are automatically redeemed at the end of the event, eliminating the need for separate payment transactions required in Phantom’s previous setup.
Positions opened before June 1st will remain tied to Karshi through DFlow. Users holding these contracts will be required to exchange their expired Outcome Tokens for stablecoins used to open positions, and the final market price may be affected by market conditions and settlement data.
This migration also changes the external systems used to determine outcomes. Old markets rely on Kalshi data processed through DFlow, while new positions may rely on oracles such as Chainlink.
Phantom warned that feed delays, inaccurate information and indexing failures could still affect market resolution and lead to financial losses.
The wallet said it does not store users’ funds, act as a counterparty to transactions, or maintain a house edge. Trades occur between users, but each market follows its own resolution rules.
The updated disclosure also prohibits users from trading contracts if they have material non-public information or if there is a direct conflict in the results.
