Cardano’s 2030 Roadmap Decision: Nine Proposals, $38.9 Million, and a Community Vote That Will Shape Its Future

Key Highlights:

• Nine Proposals, One Vote: IOG has submitted nine treasury proposals totaling $38.9 million for Cardano’s 2030 roadmap. Community delegates (DReps) have until May 24, 2026 to approve or reject them.
• The Leios Upgrade is the Centerpiece: Ouroboros Leios aims to boost Cardano's throughput from 10-15 TPS to 200-1,000+ TPS (theoretically up to 10,000 TPS), with a public testnet scheduled for June 2026.
• Babel Fees & Bitcoin DeFi: One proposal lets users pay fees in non-ADA assets (stablecoins, native tokens). Another, Pogun, is an engine to bring Bitcoin liquidity into Cardano via trust-minimized bridges.
• Recent Milestones: The Van Rossum hard fork optimized Plutus (25% less script overhead), the Midnight privacy sidechain launched with Google Cloud & MoneyGram, and a new Visa debit card lets holders spend ADA.
• On-Chain Data Shows Accumulation: Wallets holding 10M+ ADA hit a four-month high (424 wallets), suggesting larger holders are positioning ahead of the vote and June testnet.

For years, Cardano has been dismissed as an academic exercise—long on research, short on results. That narrative is now being tested. In late April 2026, Input Output Global (IOG) published nine treasury proposals outlining its development roadmap through 2030, with a total ask of $38.9 million—roughly half of what IOG requested last year. The organization cites operational self-sufficiency as the reason, but whether that framing holds depends entirely on whether the technology ships on schedule.

The Leios Upgrade: Cardano’s Speed Leap

The centerpiece of the roadmap is Ouroboros Leios, a protocol upgrade that breaks the link between transaction endorsement and block production. By introducing a two-tier system—input blocks processing transactions in parallel while ranking blocks handle finalization—Leios aims to push Cardano from its current 10-15 transactions per second (TPS) to 200-1,000+ TPS under normal load, with theoretical peaks up to 10,000 TPS.

IOG has requested 62.1 million ADA (~$15.8 million) specifically for Leios-related node upgrades, monitoring, and security audits. A public testnet is scheduled for June 2026, with a mainnet launch targeted before the end of the year.

The Other Eight Proposals: Beyond Speed

The roadmap does not stop at raw throughput. Key among the other proposals:

• Babel Fees: Allows users to pay transaction costs in non-ADA assets such as stablecoins or native tokens, removing a major friction point for new users.
• UTXO HD: An engineering change to keep node operation viable on standard residential hardware as the ledger grows, preserving decentralization.
• Pogun: An end-to-end Bitcoin DeFi engine designed to route Bitcoin liquidity into Cardano through trust-minimized bridges and credit markets, with a mainnet credit market launch scheduled for Q2 2026.

Recent Developments: Hard Fork, Sidechain, and a Visa Card

Several recent milestones provide context for the vote:

• Van Rossum Hard Fork (April 2026): Moved Cardano to Protocol Version 11, optimizing the Plutus smart contract engine and reducing script execution overhead by approximately 25%—a necessary step before Leios can land.
• Midnight Sidechain Launch (March 31): A privacy-focused sidechain with its own token (NIGHT), launched with institutional validators including Google Cloud, MoneyGram, and Worldpay.
• Visa Debit Card (April 22): Launched by EMURGO and Wirex, allowing holders to spend ADA and 680+ other assets at standard merchants, with 8% crypto rewards.

On-Chain Data Heading Into the Vote

As of early April, the on-chain data shows:

• Wallets holding 10 million ADA or more hit a four-month high at 424 wallets, suggesting accumulation from larger holders ahead of the June testnet.
• Total Value Locked (TVL) in Cardano’s DeFi ecosystem sits around $132 million—well below Ethereum and Solana. The market-cap-to-TVL ratio of roughly 66x indicates that ADA holders have not yet rotated into on-chain activity in significant numbers.

The 2030 Targets and the Vote

The long-term targets attached to the roadmap include:

• 324 million annual transactions and one million monthly active wallets by 2030
• TVL projected at $3 billion, up from the current $132–500 million range
• Analyst price projections for ADA by 2030 range from $1.20 to $5.00 (current price roughly $0.25–0.80)

May 24: The Deadline That Decides the Roadmap

The most immediate deadline is May 24, 2026. That is when Delegated Representatives (DReps)—the governance participants who vote on treasury proposals under Cardano’s current framework—close the voting window on all nine submissions.

For the first time, IOG’s development funding does not get approved by IOG. It gets approved or rejected by the community that holds the network’s governance tokens. The June testnet for Leios will then serve as the first concrete test of whether the technical ambitions in these proposals are being executed on schedule.
