Cardano’s upcoming Protocol Version 11 upgrade, known as Van Rossem, is set for a mainnet governance action submission on May 29, placing the network’s decentralized coordination to a live test. The hard fork, which introduces Plutus script enhancements, zero-knowledge (ZK) cryptographic primitives, and stake pool security improvements, arrives at a time when Cardano’s DeFi usage metrics lag far behind its $9.2 billion market capitalization.
Intersect, the organization overseeing governance, submitted the PreProd hard fork action on May 8, but the Hard Fork Working Group withheld its ratification recommendation due to readiness concerns around Ogmios, a critical infrastructure component. This makes the May 29 timeline conditional on resolving those dependencies. Under the Conway-era governance bootstrapping rules, only the Constitutional Committee and stake pool operators (SPOs) will vote on this action, marking the first major coordination test at this scale.
The upgrade packs significant technical improvements. Plutus, Cardano’s smart contract environment, will see all built-in functions available across versions V1, V2, and V3, along with new built-ins for arrays, list handling, and optimized multi-asset value operations. More notably, CIP-133 introduces efficient multi-scalar multiplication over the BLS12-381 curve—a primitive widely used in ZK proofs and SNARKs—while CIP-109 adds modular exponentiation as a built-in. IOG has already connected this work to its Halo2-Plutus verifier and the Midnight-Cardano ZK bridge, giving the cryptographic additions a product roadmap. Additionally, V11 enforces VRF key uniqueness for stake pools, automatically preventing key reuse.
Despite these advancements, on-chain data from DefiLlama shows a stark usage gap. Cardano holds approximately $129 million in total value locked (TVL), $46.7 million in stablecoins, and just $615,000 in 24-hour DEX volume. In contrast, Solana runs over $6 billion in TVL and $1.14 billion in daily DEX volume, while Ethereum’s DeFi ecosystem locks $43.4 billion. Cardano’s market-cap-to-TVL ratio stands at roughly 72x, compared to Solana’s 8x and Ethereum’s 6x, leaving little room for disappointment if developer adoption of V11’s improvements runs slow.
Against this backdrop, Charles Hoskinson, Cardano’s founder, responded to the launch of Starknet’s strkBTC Bitcoin bridge by calling the decentralized Bitcoin DeFi sector “the single largest area of growth for DeFi” and “a race we can win.” He highlighted Midnight, Cardano’s UTXO-based privacy partner chain, as structurally compatible with Bitcoin and capable of importing BTC liquidity through ZK protocols. With Cardano’s daily revenue at just $477 and TVL nearly 80% below its 2024 peak, the push toward Bitcoin DeFi represents a strategic attempt to inject external capital into an underutilized smart contract ecosystem.
If the governance action proceeds smoothly and developers begin adopting the new primitives, V11 could form the technical foundation for a credible Cardano narrative through the second half of 2025. However, any delays in Ogmios or other infrastructure readiness, coupled with the historically slow translation of technical upgrades into sustained on-chain activity, could keep ADA rangebound against faster-growing chains.
