Please describe your proposed solution and how it addresses the problem
Cardano’s adoption problem isn’t about capability, it’s about reach. Most crypto users live inside multi-chain wallets and aggregators. Asking them to install a new wallet, learn a different UX, and bridge assets just to “try Cardano” is a high-friction detour. We’re removing that detour by taking Cardano to where users already are.
Our plan is straightforward: integrate Cardano directly into the tools people use every day. Ctrl Wallet on the wallet side, and JunctionFi on the routing/aggregation side. Then using Mynth as the interoperability layer.
From a user’s point of view, Cardano simply becomes “one more chain” alongside 22+ others they already know. No extra steps, no new seed phrase, no mystery bridges, just tap, transact, done.
Why this approach? Because behavior change is the hardest part of growth. Meeting users in familiar interfaces collapses the learning curve and dramatically reduces drop-off. By plugging Cardano into established multi-chain flows, we make first contact effortless and repeat usage natural. That’s how you convert curiosity into real activity and liquidity.
Who we’ll engage:
How it works under the hood:
What’s unique here is the combination: an interoperability layer purpose-built for Cardano + a widely used multi-chain wallet + an established aggregator. Plenty of projects offer bridges or “yet another wallet.” We’re avoiding both traps. Instead, we’re stitching Cardano into the existing multi-chain fabric so discovery and usage happen in the places users already trust.
How we’ll demonstrate impact (briefly—full impact plan follows in the next section):
We’ll instrument these with partner analytics and public dashboards so progress is visible and verifiable throughout delivery. We’ll coordinate announcements and how-to content with all partners’ X and Discord channels, supplemented by targeted updates in Ctrl Wallet and JunctionFi surfaces where appropriate (release notes, in-app prompts, docs). The message is simple: “Cardano works where you already are.”
By collapsing the onboarding cost to near zero, we unlock a much larger audience, new liquidity pathways, and a smoother path for builders to reach users. It’s a practical, low-friction way to make Cardano feel mainstream in a multi-chain world, without asking the world to change its habits first.
Please define the positive impact your project will have on the wider Cardano community
Success for the community looks like Cardano becoming effortless to use inside tools people already trust. By meeting users in Ctrl Wallet and routing through JunctionFi, we expect more first-time users to try Cardano, more liquidity and order flow to reach the network with less friction, and a lower onboarding cost for builders who want Cardano exposure without rebuilding their UX or support.
We’ll measure impact with a mix of on-chain and product metrics and publish them in a way the community can verify. On the adoption side, we’ll track unique non-Cardano users completing their first Cardano transaction through our partners, time-to-first-transaction, completion rate from intent to confirmation, and short- and medium-term retention. For liquidity and flow, we’ll monitor net inflow and routed volume into Cardano attributable to multi-chain entry points. To reflect ecosystem health, we’ll look at the spread of activity across use cases, like sending, swapping, staking, and payments, plus builder adoption of the Mynth layer, and partner counts.
Data will come from public chain sources for objective measures such as volume, unique addresses, and transaction counts. We’ll document our attribution methods so anyone can understand how “new-to-Cardano” and “routed via partners” are defined. We’ll also gather qualitative feedback through user interviews, partner AMAs, and support logs to capture friction and wins that numbers alone can miss.
The benefits compound beyond the initial wave of users. Builders gain immediate reach into multi-chain audiences without rewriting onboarding or support, which shortens time to market and reduces cost. Liquidity providers and market makers see stable, repeatable routes into Cardano via JunctionFi, which encourages them to commit deeper books and tighter spreads. Wallet and dApp teams across Cardano inherit safer, clearer flows because our UX guardrails, fee transparency, and transaction safety checks set expectations users now recognize from other chains.
Importantly, this work leaves durable assets behind. The interoperability layer, routing integrations, analytics pipelines, and documentation persist after delivery and can be reused by the next wave of teams. Each additional partner that connects through Mynth reduces marginal integration effort and creates a larger surface area where Cardano is one tap away. Over time, the network benefits from a flywheel: lower friction invites more users, more users justify better liquidity, better liquidity improves execution, better execution brings more builders, and the cycle repeats.
Lowering the effort of trying Cardano turns more casual explorers into repeat users, which lifts activity across wallets, dApps, and services. Better routing and smoother UX increase the odds that liquidity providers and builders keep supporting Cardano after the initial push. The instrumentation, routes, APIs, and documentation we set up become durable assets the ecosystem can keep using to grow over time.
In short, we’ll prove value by making Cardano easier to reach.

Summary:
How does the cost of the project represent value for the Cardano ecosystem?
This is a high-leverage use of funds because it removes the single biggest adoption barrier: friction. We’re taking Cardano to where multi-chain users already live. Instead of paying to build yet another wallet or bridge that fragments attention, we plug Cardano directly into a proven wallet experience (Ctrl Wallet) and an established routing layer (JunctionFi) via Mynth’s interoperability stack. The result is immediate, measurable value: first-time non-Cardano users can transact without new setup, liquidity can route in with smart aggregation, and builders gain distribution to audiences across 22+ chains.
The proposed costs align with standard market rates for blockchain development and related services. Experienced developers in this field commonly command hourly rates in line with those used for the calculations, reflecting both the complexity of interoperability engineering and the need for reliability at production scale. Security allocations are justified given the high-value nature of stablecoin transactions. Penetration testing and bug bounties are industry-standard measures to ensure user safety and instill trust. Marketing efforts are equally critical: without a strong adoption push, even the best infrastructure risks underutilization. Strategic content, PR, and community engagement are proven methods in Web3 markets to accelerate adoption and build network effects.
You get reusable infrastructure rather than one-off hype. APIs, routing integrations, transaction safety checks, analytics, and documentation become shared assets the whole ecosystem can build on, lowering the marginal cost of every future integration. Because we’re leveraging established products and in-kind partner effort, more of the budget goes directly to shipping connectivity and adoption, not reinventing primitives. The result is a compounding flywheel. Easier access brings more users, better execution attracts deeper liquidity, stronger liquidity invites more builders. The community’s investment keeps yielding new activity and opportunities long after delivery.
Turn Cardano from a detour into a default. By wiring it into Ctrl Wallet and JunctionFi via Mynth, Cardano becomes one tap for multi-chain users. Cardano shows up exactly where millions of multi-chain users already live. This is how millions of users, billions in flow, and builders across 22+ chains finally reach Cardano without even realizing they took a new path.
