Cardano Prepares “Largest Upgrade” Yet

The moves come as stablecoins go increasingly mainstream and competition for on-chain credit markets intensifies.

Linda a.k.a CryptoFly says Cardano’s next hard fork, dubbed the Van Rossem upgrade, is currently in its on-chain voting phase and is expected to activate sometime in July.

This will bring Cardano to “version 11” and deliver several technical changes aimed at smart contract performance and network security.

Plutus, Cardano’s smart contract language, is getting three separate optimizations that should make contracts “cheaper and faster to run,” potentially lowering costs for DeFi protocols and expanding what builders can do on-chain.

The upgrade also includes ledger and node enhancements designed to prevent two stake pools from registering or operating with the same verifiable random function (vRF) key — the cryptographic mechanism used to fairly select block producers.

According to CryptoFly, this closes off a theoretical edge case and tightens stake pool security.

The Van Rossem fork also lays groundwork for “Leios” Cardano’s major scalability upgrade.

A public Leios scaling testnet went live in June, with the host citing internal expectations that it could eventually push throughput to “10 to 65 times the speeds we have today” though those numbers remain to be proven under real-world load.

The centerpiece of the YouTube episode revolves around Cardano’s RealFi Phase One, which launches its testnet on July 6.

This initiative is built around a new stablecoin, USDR, described as “by the real economy” and designed to integrate real-world credit flows into on-chain yield.

Holders who stake USDR are expected to earn returns generated from off-chain assets such as government treasuries, corporate bonds, and direct lending to real businesses. The analyst stresses that USDR is “just the first primitive” in a broader RealFi roadmap that also contemplates Bitcoin DeFi concepts, though details on those extensions remain vague.

Charles Hoskinson has publicly floated a target of $1 billion in total value locked (TVL) for RealFi, but the commentator warns that figure should be taken “with a grain of salt,” noting both the long history of RealFi promises on Cardano and the now-crowded stablecoin landscape, where banks and payment giants are rolling out their own rails.

Cardano’s upcoming weeks combine a classic scaling and performance upgrade with a more ambitious attempt to tie stablecoin yield directly to traditional credit markets.

If the Van Rossem fork and Leios scaling deliver as advertised, they could ease pressure on fees and capacity just as RealFi seeks to attract capital via USDR and related products.

The risk is execution: RealFi has been a narrative around Cardano for years, and the stablecoin arena is now saturated with well-funded incumbents.

Still, a functioning testnet for both Leios and USDR gives analysts clearer milestones to track — from throughput metrics to early adoption and, eventually, whether on-chain yields from “real-world” credit can compete with established DeFi returns.
