Charles Hoskinson proposed that Ripple integrate Cardano's Midnight sidechain, arguing the privacy layer could unlock more than $100 billion in idle XRP liquidity for DeFi and tokenization.
Cardano founder Charles Hoskinson proposed that Ripple integrate the Midnight privacy sidechain, arguing it could unlock more than $100 billion in dormant XRP for DeFi and tokenization.
"XRP Ledger was designed for payments, not programmable finance, and Midnight's zero-knowledge architecture could bridge that gap without requiring Ripple to overhaul its core infrastructure," Hoskinson said.
The XRP Ledger processes about 1,500 transactions per second with three-to-five second finality but lacks native smart contract support for lending, yield generation, and other DeFi activities. Midnight, developed by Input Output Global and detailed in a September 2023 whitepaper, uses zero-knowledge proofs to enable confidential smart contracts across multiple blockchains. Under the proposal, XRP would be wrapped onto Midnight via a cross-chain bridge, allowing holders to deploy tokens as collateral in DeFi protocols while preserving transaction privacy.
No formal integration agreement exists between Ripple and Input Output Global, and the $100 billion figure — which appears to reflect XRP's market capitalization reframed as dormant capital — has not been independently verified. Still, the pitch arrives as institutional interest in XRPL grows: JPMorgan, Mastercard, and Ondo Finance conducted a tokenized Treasury redemption pilot on the ledger in May 2026.
The Web 2.5 Framing and What's at Stake
Hoskinson categorized Ripple alongside Tether, Circle, and Binance as "Web 2.5" — entities that bridge traditional finance and crypto without full DeFi programmability. The framing benefits Midnight more than Ripple in the short term: the sidechain needs access to markets, and XRP represents a large pool of underutilized on-chain capital. Ripple's RLUSD stablecoin already dominates liquidity on XRPL, but the ledger lacks a significant DeFi ecosystem.
Institutional DeFi Requires Privacy
The JPMorgan-Mastercard-Ondo pilot demonstrated institutional traction for tokenization on XRPL, but it did not address data transparency — a barrier to broader institutional DeFi adoption. Financial institutions require confidentiality in their on-chain relationships. Midnight's zero-knowledge proof architecture offers selective disclosure, allowing institutions to prove regulatory compliance without revealing transaction details. Hoskinson linked this capability to the $10 trillion real-world asset market, arguing institutions will only tokenize assets on chains that ensure privacy, compliance, and interoperability.
For the proposal to move beyond a strategic pitch, Ripple and Input Output Global would need to agree on a technical roadmap and formal partnership — steps neither party has committed to publicly. Until then, the $100 billion figure remains an aspirational estimate of what could be possible if two of crypto's largest ecosystems find common ground.
