Wormhole × Cardano: Cross-Chain Infrastructure Proposal — Pre-Submission Discussion
Posted by: Wormhole, ahead of on-chain submission via Intersect Budget Committee
Why we’re posting this now
Wormhole will shortly submit a proposal to the Cardano Treasury for $5,000,000 USD equivalent in ADA as a single one-time withdrawal upon vote approval, to deploy a comprehensive cross-chain infrastructure stack on Cardano.
We are posting this to the forum a few days ahead of formal on-chain submission via Intersect, for two reasons:
- Early DRep and community feedback: to surface objections, refinements, and questions before the on-chain vote begins, so the version DReps vote on already reflects community input.
- Transparency on submission timing: so the community is aware that this proposal is entering the queue, alongside other pending budget asks.
Direct engagement is welcomed in the comments below or via the Cardano Foundation governance team.
What this proposal funds
The proposal deploys Wormhole’s full infrastructure stack on Cardano — the same stack securing $70B+ in cumulative cross-chain volume across the industry’s leading blockchains.
Specifically, four capabilities that are not currently available to Cardano via any other infrastructure provider in the near term:
- Institutional Real-World Assets: connection rails for Securitize ($4B+ AUM: BlackRock BUIDL, Apollo, Hamilton Lane, VanEck) and DigiFT (UBS uMINT, Invesco, China Merchants Bank, dual MAS/HKSFC regulated), both of which use Wormhole as their cross-chain interop layer.
- Native multichain stablecoins: using Wormhole’s NTT (Native Token Transfer) framework for true mint/burn — no wrapping, no fragmentation. M0 (the $779M wholesale stablecoin platform powering MetaMask mUSD and Noble USDN) is Wormhole’s exclusive NTT partner. Pipeline includes Sky/USDS, RLUSD, and Transfero BRZ.
- Bitcoin liquidity: Cardano’s eUTXO architecture shares structural DNA with Bitcoin. Guardian-secured BTC custody positions Cardano as a natural programmable layer for Bitcoin capital, with tBTC and sBTC in the pipeline.
- Multichain ADA: within 60 days of mainnet, ADA launches as a native NTT asset on Ethereum and Solana, with additional chains to follow. 200+ existing Wormhole-integrated DeFi applications gain access to ADA.
Budget structure
The total ask is $5,000,000 USD equivalent in ADA, structured as a single one-time withdrawal upon vote approval and broken down across two work packages.
Work Package 1: Infrastructure, Integration & 24-Month Operational Support: $4,000,000. This is split between $2,500,000 for Integration & Development (the joint engineering effort with Cardano Foundation engineers — Aiken contracts, NTT framework, Executor/Relayer, SDK, Portal/Connect with bridge + swap and bridge + deposit flows, WormholeScan indexing, and multichain ADA on Ethereum and Solana), and $1,500,000 for Maintenance & Support (24 months of full operational support across the 19-validator Guardian network — covering executor relayers, SDK upkeep, indexing, observability, and security monitoring).
Work Package 2: Bridge TVL Campaigns & Ecosystem Activation: $1,000,000. This is the responsive part of the proposal — deployment is being shaped through ongoing socialization with the Cardano ecosystem, and DRep input on activation priorities will directly influence how it is allocated across Portal Bridge TVL campaigns, DEX LP bootstrapping, lending protocol incentives, cross-chain flow incentives, and co-incentive programs with asset partners.
Single one-time treasury withdrawal upon vote approval. No recurring fees. No tranche-gated disbursement. Quarterly delivery reporting against published milestones.
The independent security audit is funded separately by Cardano via the Foundation’s preferred audit partners — outside this $5M envelope. This gives the community direct control over auditor selection. Wormhole Labs manages audit-readiness, auditor engagement, remediation, and public report publication.
Any unused portion of WP2 returns automatically to the Cardano Treasury at the end of the 12-month program. The community is not exposed to risk on funds that don’t get deployed.
How this proposal was shaped
This proposal has been iterated extensively with the Cardano ecosystem before submission:
-
Cardano Foundation provided input throughout the proposal’s development. CF’s feedback shaped partner ordering (Securitize first) and the addition of native DeFi flow integrations.
-
Pi Lanningham (SundaeSwap, DRep) drove the choice of Aiken over Plutus for accessibility and tooling maturity, the volume-over-TVL emphasis, and the inclusion of bridge + DeFi flow integrations so users arriving on Cardano are immediately active in DeFi rather than parking idle TVL.
-
FluidTokens shaped asset partner prioritization toward Securitize and tokenized securities.
DReps can verify these attributions directly with the named individuals.
Why now: the structural argument
Cross-chain infrastructure on Cardano has been a recognized gap for some time. The Critical Integrations Budget (CIB) passed with 85%+ DRep approval and explicitly identified cross-chain bridges as essential infrastructure.
Three structural barriers have prevented cross-chain providers from delivering on Cardano to date:
-
eUTXO complexity vs EVM-default tooling. Most cross-chain providers built EVM-first; their architectures translate poorly to Cardano, requiring expensive retrofitting they have avoided. Wormhole has shipped four alt-VM integrations to date (Sui, Aptos, NEAR, XRPL) and is structurally committed to building Cardano natively in Aiken — with CF engineers leading contract development.
-
Asset pipeline mismatch. Earlier infrastructure attempts arrived without asset partners ready to deploy. Empty rails generate no usage. This proposal arrives with Securitize, DigiFT, and M0 — assets that cannot reach Cardano through any other infrastructure provider in the near term.
-
Activation gap. “Open the bridge and hope” produces idle TVL, not real usage. The $1M activation budget, native bridge + DeFi flow integrations, and explicit volume-over-TVL focus address this directly with budget commitments, not narrative.
On execution speed: the proposal targets a 5–6 month active engineering window. Wormhole’s track record on alt-VM integrations is publicly verifiable on WormholeScan. To our knowledge, no other major cross-chain infrastructure provider has yet announced specific Cardano deliverables, a timeline, a budget, or entered governance. Cardano cannot afford to wait 12–18+ months for cross-chain infrastructure given the competitive pressure on RWA capital flows and stablecoin pipelines that are actively allocating to other chains today.
What this proposal does NOT promise
We want to be explicit about this, because vague promises are how proposals lose community trust:
- It does not promise specific institutional partner deployment dates — partners decide their own deployment timelines.
- It does not promise immediate $100M+ TVL — flows compound over months.
- It does not promise that competing infrastructure won’t eventually launch on Cardano — others will arrive in time.
- It does not promise that all flows will be retail-meaningful — some are institutional rebalancing.
What it does promise: verifiable infrastructure delivery, real on-chain activity that pays fees to the treasury, native DeFi flow integrations with Cardano DEXs and lending protocols, and quarterly transparent reporting against published milestones.
Outcome KPIs (all on-chain verifiable via WormholeScan)
All KPIs are verifiable on WormholeScan in real time. Each is presented with a 6-month target and a 12-month target.
- Cross-chain transactions on Cardano (treasury fees): 10,000+ at 6 months; 50,000+ at 12 months
- Cross-chain volume via Wormhole rails: $25M+ at 6 months; $125M+ at 12 months
- Stablecoin TVL inflow: $5M+ at 6 months; $30M+ at 12 months
- Asset partners actively evaluating Cardano: 3+ at 6 months; 4+ live at 12 months
- Cardano DeFi protocols with pre-configured markets: 2+ ready at 6 months; 4+ active at 12 months
- Multichain ADA chains live (ETH, SOL primary): 2+ at 6 months; 4+ at 12 months
- Bridge + swap / bridge + deposit flow integrations: 2+ live at 6 months; 4+ live at 12 months
Not measured: booth contacts, marketing impressions, partner introductions, social media reach, press hits. The community verifies on-chain. It does not have to trust.
Sell pressure & treasury outflow context
The $5M ask represents approximately three epochs of total Cardano staking rewards distributed at current prices. The market absorbs this scale routinely.
The genuine community concern, accurately framed, is compound disappointment pressure — proposals that pass thinly or are later viewed as wasteful create downstream friction for future asks. This proposal is structured specifically to prevent that dynamic:
- Single one-time withdrawal — no further treasury asks during the 24-month delivery window
- 24 months of operational support included — no recurring fees, no year-on-year drain
- Unused incentive funds auto-return — up to $1M of WP2 returns to treasury if not deployed
- Outcome KPIs verified on WormholeScan in real time
- Quarterly progress reporting — public reports against scope and KPIs throughout the 24-month window
- Community shaped before submission — through this forum post and prior CF/DRep engagement

Frequently Asked Questions
We’ve anticipated the questions DReps and the wider community are most likely to ask. We’ve answered them here directly. Additional questions are welcomed in the comments below.
Why $5M? How does this compare to other proposals currently in queue?
$5M is what the work actually costs. The breakdown is detailed in the proposal: $4M covers integration, infrastructure, and 24 months of operational support; $1M covers ecosystem activation and is responsive to community input on deployment priorities. By comparison, this is materially smaller than the multi-year fund proposals currently being discussed in the community and it is structured as a single one-time withdrawal rather than tranched over multiple years. DReps approving this proposal commit to a defined, capped amount with no further treasury asks during the 24-month delivery window.
Why a single withdrawal instead of milestone-tranched disbursement?
Two reasons. First, the engineering work in WP1 is substantially front-loaded — Aiken contract development, Guardian network configuration, NTT framework, indexer integration — all delivered within the first 6 months. Tranched disbursement against later milestones doesn’t actually map to when the costs are incurred. Second, accountability does not depend on disbursement gating. Every cross-chain transaction is verifiable on WormholeScan in real time. Quarterly delivery reports are public. Wormhole’s reputation across 40+ chains depends on delivery, and that reputational stake is real. Additionally, any unused portion of WP2 (up to $1M) returns automatically to the Cardano Treasury at the end of the 12-month program — DReps are not exposed to risk on funds that don’t get deployed.
How is success measured? What happens if Wormhole underperforms?
Success is measured against the seven outcome KPIs listed in the table above, all on-chain verifiable via WormholeScan. Quarterly progress reports — published publicly throughout the 24-month operational window — track delivery against scope and KPIs. If performance underwhelms, three substantive consequences apply: (1) unused WP2 incentive funds return to Treasury automatically, (2) Wormhole’s reputation across the broader cross-chain ecosystem is materially exposed, and (3) the community has full transparency to escalate concerns through governance channels. We are deliberately not promising specific outcomes we cannot guarantee — see “What this proposal does NOT promise” above.
What happens if the Treasury withdrawal vote does not pass?
If the on-chain vote does not pass the required thresholds, Wormhole Foundation will assess the reasons in consultation with the Cardano Foundation and the community. Options include: revising the proposal based on DRep feedback and resubmitting, or treating the outcome as a community signal that Wormhole’s proposed approach is not currently the preferred path forward. Either way, no Treasury funds are committed unless the vote passes. The 1,000 ADA proposal submission donation is the only Treasury exposure prior to vote outcome, and that donation is already programmatically returned to the Treasury via the submission mechanism.
What happens to deployed Cardano assets if Wormhole deprecates the integration in the future?
This is an important question and worth answering directly. Wormhole’s standard practice across 40+ chain integrations is that deprecation, when it occurs, is a structured multi-month process rather than an abrupt shutdown. Users retain the ability to bridge assets back to their origin chains throughout the deprecation window. NTT-issued assets, by design, can be redeemed at the issuer’s discretion across whatever chains the issuer chooses to maintain. The 24 months of operational support included in this proposal commits Wormhole to maintaining the Cardano integration for that period at minimum. Beyond 24 months, ongoing maintenance arrangements would be subject to subsequent community discussion — Wormhole would not unilaterally deprecate without first proposing a path forward to the Cardano community and providing adequate notice for asset migration.
Closing
Wormhole is committed to building this with Cardano, not for Cardano. The joint engineering model with CF engineers leading Aiken contract development is the structural expression of that commitment.
We welcome rigorous scrutiny. The numbers are transparent, the deliverables itemized, the KPIs on-chain verifiable. Funds that may not be deployed return automatically. The infrastructure stack being deployed is the same one securing $70B+ across 40+ chains.
We look forward to community feedback ahead of on-chain submission.
