Input Output (IO) says Cardano’s treasury-funded strategy passed an early test: across Q4 2025 and Q1 2026 the company reported measurable progress on 16 of 18 commitments it had funded — and returned money for the two that didn’t make the cut. In a delivery report IO framed the experiment bluntly: funding must produce publicly verifiable output, or it goes back to the treasury.
Key takeaways
- IO progressed 16 of 18 treasury-funded commitments in Q4 2025–Q1 2026. Two — Acropolis and tiered pricing — were canceled and their funds returned. “Every outcome in this report is publicly verifiable,” IO said.
- USDCx launched on Cardano 84 days after announcement; more than 15 million USDCx minted in the first week. Cardano DeFi TVL rose from $127M to $142M during that period, with Minswap, Liqwid and SundaeSwap hosting live liquidity pools.
- Interoperability advances include LayerZero integration with Cardano and Midnight, connecting the chain to 160+ blockchains and more than $80B in omnichain assets — called “the single largest interoperability unlock in the ecosystem’s history.”
- External ecosystem wins noted: CME Group launched Cardano futures in February; Coinbase added ada as collateral for on-chain loans; Midnight mainnet went live; and ada is accepted at 137 SPAR stores in Switzerland.
- Engineering and infrastructure updates focused on node reliability, security, scaling, and developer tooling.
Adoption: USDCx and DeFi traction
IO highlighted an immediate adoption milestone: USDCx went live on Cardano in Q1 2026 just 84 days after its announcement. The asset saw brisk uptake — more than 15 million USDCx minted during week one — and coincided with DeFi TVL climbing from $127M to $142M as Minswap, Liqwid and SundaeSwap provided liquidity. For IO, that is tangible proof funding can convert to on-chain activity.
Interoperability: LayerZero and Midnight
LayerZero’s announced integration with Cardano and Midnight is presented as a major connectivity boost: it links the ecosystem to over 160 blockchains and upwards of $80 billion in omnichain assets. IO emphasized the significance for Midnight, whose selective disclosure and zero-knowledge proof architecture stand to benefit from broader cross-chain rails.
Ecosystem milestones beyond IO
The report calls out a string of third-party milestones that underscore broader momentum: CME’s Cardano futures (Feb), Coinbase permitting ada as collateral for on-chain loans, Midnight’s mainnet, and retail acceptance of ada at 137 Swiss SPAR stores.
Node, security and operator tooling
IO shipped Cardano node releases 10.5.4 and 10.6.2 with improvements to network connectivity, system monitoring, and readiness for upcoming protocol versions (v11 and v12). The KES agent reached v1.0 — a separation of cryptographic key handling from the node process that reduces the key-related attack surface, a benefit IO specifically ties to Cardano’s more than 3,000 stake pools.
UTXO HD and lower memory costs
A notable infrastructure change was UTXO HD: moving the UTXO set from memory to disk. IO says this cut node memory utilization by up to 80%, which should lower hardware costs and make running nodes less resource-intensive for operators.
Scaling as a three-track plan
Rather than a single “big bang” upgrade, IO frames scaling as three parallel efforts:
- Mithril: Reached its first stable release (distribution 2603.1) with support for a decentralized message queue protocol, moving the protocol closer to coordinator-free operation.
- Hydra: Moved through releases 1.0.0 to 1.3.0 with production-focused improvements — faster node restarts, chain-sync drift reporting, deposit/decommit fixes — and active testing with real users. IO highlights Pondora’s Echo as the first non-custodial Hydra implementation and points to the VTech Hydra SDK.
- Leios: The base-layer throughput upgrade produced a first working prototype that can produce and distribute endorser blocks in a local multi-node setup, handling large blocks and simulated network delays.
Developer tooling, formal methods and research
Plutus received several engineering improvements — Van Rossem hard fork features, faster Flat decoding, optimized bytestring-integer primitives, and Plinth tool upgrades. Cardano High Assurance opened early access to five companies testing automated formal verification at the UPLC level.
Research items included the close of Work Package 25 (all funding milestones met after a public consultation that reached more than 24,000 people), two papers at Financial Cryptography 2026, and the recognition of IO chief scientist Professor Aggelos Kiayias as an ACM Fellow.
What’s next (Q2 targets)
IO’s roadmap for the coming quarter includes:
- Protocol version 11 intra-era hard fork coordinated by Intersect
- Node v10.7
- Mithril 2608
- A Leios public testnet
- Work Package 26
- The Cryptographic Tools for the Blockchain workshop at Eurocrypt 2026
Market snapshot
At press time, ada traded at $0.2491.
Bottom line
IO’s delivery report frames Cardano’s treasury model as a practical experiment: fund projects, demand transparent delivery, return funds when targets aren’t met. The company points to measurable adoption (USDCx), interoperability wins (LayerZero + Midnight), and concrete engineering progress across nodes, scaling tech and formal verification as evidence the model can drive visible results.
