Tron founder Justin Sun has filed a lawsuit against World Liberty Financial, alleging the wrongful freezing of his token holdings. Sun claims his assets were frozen without justification and threatened with destruction. The lawsuit, filed in a California federal court, follows failed private negotiations to resolve the issue. Sun is reportedly the largest individual investor in the project, which has connections to the Trump family. In other developments, prediction market platform Kalshi is expanding into the crypto derivatives market. The company plans to launch cryptocurrency-linked perpetual futures, including contracts tied to Bitcoin. This move marks a shift from event-based contracts to continuous financial derivatives, potentially offering a regulatory edge under the U.S. Commodity Futures Trading Commission. Additionally, DoorDash is exploring stablecoin payments in partnership with Tempo, aiming to enhance payout efficiency across 40+ countries. Meanwhile, Blockchain.com has launched a self-custodial trading feature for perpetual futures, allowing users to trade directly from their wallets with up to 40x leverage, maintaining control over private keys.
