Cardano founder Charles Hoskinson celebrated the launch of the RealFi testnet, calling it one of the most important releases in the network’s history. The Phase 1 testnet, now live, allows users to swap test assets for test USDr, stake test USDr to receive test sUSDr, and later unstake back to test USDr. RealFi aims to build a stablecoin system that links blockchain liquidity with real-world credit markets, putting idle capital to work.
Hoskinson shared the announcement on X, asking followers if they were ready to “bank the unbanked” and describing the launch as a defining moment for Cardano. The testnet is more than a preview — it represents a step toward stronger decentralized finance on Cardano, which supporters say needs more useful applications to boost ecosystem activity.
The RealFi news coincided with a new debate over UTXO models. Ethereum developers discussed bringing native UTXO functionality to Ethereum, arguing it could drastically reduce permanent state. Hoskinson responded sharply: “It’s literally a crime in the Ethereum inner circles to mention Cardano. EUTXO is the biggest innovation in the smart contract space and they are literally trying to copy it.” His comments highlight a long-standing rivalry between the two ecosystems, rooted in his departure from Ethereum to launch Cardano and a fundamental disagreement over blockchain design.
Cardano community members also pointed to data from Chainspect showing what they call the most honest transactions-per-second figures among major Layer 1 networks, and expressed anticipation for the upcoming Leios upgrade, which promises higher throughput without sacrificing decentralization.
