Clear signing of Cardano Top 5 dApps & Ledger Button integration
Ledger Technologies SAS
ID: 69fd6ef7f9ebc26d057f51d9
This proposal aims to bridge the gap between secure cold storage and the Cardano DeFi ecosystem. Currently, ADA is a top-5 asset secured on Ledger, yet activity is largely limited to native staking. We propose a full integration that allows retail ADA holders to connect to Cardano dApps directly through Ledger Signer. This integration is centered on two industry-leading security pillars: **Clear Signing** and **Ledger button**, ensuring that as liquidity flows into Cardano DeFi, user security remains uncompromised.
- USD peg is aggressive vs current spot (implied buffer ?%).
Scorecard
How this score works
Each criterion is worth between 1 and 4 points. The score is the points earned out of the points on criteria that have been answered — shown as a percentage. Green is 75% or higher, Amber is 50–74%, and Red is below 50%.
Some criteria are checked automatically against the proposal data (open source, doxxed team, treasury return clauses, etc.). Others are human-judgment calls — value for money, public good, whether the deliverables are realistic. Those stay blank until a DRep ticks them.
Criteria can also be marked Not applicablewhen they don't fit the proposal — for example, "open source" doesn't apply to a DAO governance proposal with no software output. Those are excluded from the score entirely, neither helping nor hurting.
Green requires 80% coverage. If less than 80% of the applicable criteria (by points) have been answered, the verdict stays at Amber — "pending review" — even when every answered criterion passes. This proposal's coverage is currently 68% (13 of 19 applicable criteria answered).

The 'Transaction Check' anti-drainer feature relies on a real-time database of known threats, but the data source / curation model / coverage for Cardano-side threats is unspecified."

The strongest case for the funding category is clear: DeFi-on-Ledger clear-signing protects retail users from drainer attacks. The weakest case is the proposal as written: no scope, no milestones, no metrics, no return, no audit, no named dApp adopters."
