Ledger Wallet Clear Signing: The Safest Way to Approve Crypto Transactions

Built for Safety, Powered by Caution

Within a decade of operations, Ledger has sold over 8 million devices and continues to secure 20% of the global digital value. Ledger takes security seriously. This time-tested security model is built on three powerful layers:

1. Secure Element: This is the heart of Ledger’s security, an EAL6+ certified secure chip often used in credit cards or biometric passports. It’s a dedicated chip that keeps your private keys offline, and also drives the secure screens/touchscreens of every Ledger device.  
2. Secure Operating System (OS): Ledger’s Secure OS is purpose-built to be immune to malware and attacks, providing an additional layer of protection. 
3. Secure Screens & Secure Touchscreens: The screen you use to verify transactions is fully isolated and tamper-proof.  It’s not connected to the internet, so there’s no risk of someone hijacking your transaction approvals.

Education is critical, especially for safe practices, like never sharing your recovery phrase, and this is why using Ledger isn’t just about having the right tools, but also being crypto cautious. Why trust third party screens or apps when you can trust yourself?

Ledger also embraces education for all interested in taking their first steps in crypto and digital ownership. It continually invests in educational resources and interactive guides through Ledger Academy to ensure users are well-equipped to handle potential risks in the real world. Social engineering will always remain a possible attack vector so ultimately, security goes beyond hardware or software, it boils down to awareness, good habits, and informed decision-making.

Security in Use: Don’t Trust, Verify 

In crypto, trusting a screen connected to the internet is never a good idea. Usual everyday screens are connected to the internet, do not have a Secure Element chip running them, and hackers can (and do) manipulate what you see on them when it comes to signing transactions.

In early May 2025, a sophisticated blind signing hack targeted Phantom Wallet users on the Solana blockchain, resulting in $1.5 million in losses across 80 victims. How did this happen?

A fraudulent NFT minting site tricked users into signing a transaction that secretly transferred SOL and SPL tokens to attackers. Phantom’s default signature prompt function was exploited, which failed to clearly display the transaction’s true intent, a classic blind signing vulnerability. This is just one example of a long line of hacks and attack vectors in web3 owing to blind signing.
That’s why Ledger takes a radically different approach with its Secure Screens and Secure Touchscreens.

Ledger’s Approach to Security

When you approve a transaction, you can see the details clearly on a tamper-proof screen that’s driven directly by the Secure Element chip. Plus, the device itself is not connected to the internet. This way, even if the screen of your third party device is compromised, you can still verify the transaction details securely.

Together, the three layers of Ledger’s security model give you peace of mind when you’re not using your device, and security in use when you are. 

Ledger understands security is not a static concept, it must evolve alongside the ever-changing digital landscape. This constant evolution ensures that Ledger remains not just a hardware wallet, but a comprehensive security solution for the future of crypto assets.

Ledger’s approach embodies the fundamental crypto principle: “Don’t trust, verify.” By offering users a fully secure, offline verification process, Ledger places complete transactional clarity into the hands of its users, helping them rely less on external trust and forcing personal autonomy by default in financial decisions.

When you use a Ledger signer, your security is automatically taken care of as far as the device and ecosystem are concerned. As soon as you connect your device, it’s already protecting you from the threat of online hacks and malware. But here’s the catch: Ledger can protect you from hacks, but not from human error. If you misplace your recovery phrase or fall for a phishing attack, even the best security system won’t be able to help.

The Problem: From Simple Transactions to Complex Smart Contracts 

When Bitcoin was first introduced, transactions were relatively simple: transferring value from one address to another. It was easy to verify the details; what you see is what you get.

However, with the introduction of Ethereum and its smart contracts, things became much more complex. Now, transactions are more than just value transfers, they can be anything from decentralized finance (DeFi) actions to NFTs or even interacting with decentralized applications (dApps).

The increased complexity has significantly expanded the attack surface. Without a clear understanding of transaction specifics, users are more vulnerable to unintended actions and exploits. This is why clear visibility and comprehensible transaction details are becoming critical elements of modern blockchain security.

What is Blind Signing? 

Blind signing is when a user approves a transaction without fully understanding or verifying what they are agreeing to.

This happens because smart contracts often involve multiple steps or instructions, and it can be difficult to know exactly what the transaction entails unless you have the right tools to review it. 

Blind signing essentially asks users to trust without verification, directly contradicting crypto’s fundamental ethos. 

Ledger recognizes blind signing as a significant vulnerability, one that has unfortunately led to billions in losses across the industry. Take Bybit’s $1.5 Billion loss in 2025 or the fall of Wazir X, an Indian trading platform that lost ~$235 million due to blind signing. 

It’s painfully obvious that there is a need for a better way to verify and secure transactions for everyone in crypto.

The Solution: Clear Signing: Making Security Simple and Transparent 

Clear Signing in web3 means showing users exactly what they’re approving in a blockchain transaction, displayed in plain language, instead of complex codes. It lets you clearly verify transaction details directly on your wallet, keeping your crypto safe from hidden scams or threats.

Ledger makes it a priority to introduce Clear Signing as a standard within all apps/dApps native to the Ledger Wallet ecosystem. By integrating this, users are now able to see all the details of a transaction before they approve it without needing to rely on third-party apps. While initially tailored for Ethereum and EVM-compatible chains, it is architected with a broader vision to encompass multiple blockchain ecosystems. 
This strategic design means you can now have confidence exploring multichain web3 ecosystems with transparent and understandable transaction details and can be universally applied. 

Ledger’s Clear Signing Initiative

Ledger’s Clear Signing Initiative offers a structured, human-readable format, enabling straightforward Ledger’s Clear Signing Initiative offers a structured, human-readable format for signing crypto transactions, enabling straightforward verification of transaction intents, recipient identities, and affected assets. At the heart of Ledger’s Clear Signing is a meticulously structured metadata format that translates complex transaction data into human-readable information. This format is organized into distinct sections:​

• Context: Provides overarching details about the transaction’s environment.
• Metadata: Contains specific information about the transaction’s components.​
• Display: Dictates how this information is presented to the user.​

By leveraging JSON paths and reference mechanisms (such as $, #, @), this structure enables wallets to accurately map and display intricate details like addresses, amounts, and timestamps in a clear and comprehensible manner. 

This approach ensures that users can easily verify transaction specifics, bridging the gap between raw blockchain data and user-friendly interfaces.

Ledger’s tamper-proof secure screen combined with the Clear Signing standard integrated into Ledger Wallet™  provides unmatched security for your digital assets. 

Clear Signing on Ledger Wallet vs Other Ecosystems

Clear signing inside Ledger Wallet is relatively straightforward because Ledger controls the entire environment; it can handle how transaction data is parsed, displayed, and approved directly on its secure screen.

However, clear signing outside of Ledger Wallet, like when using third-party dApps or wallets, depends on dApp developers providing metadata (clear, human-readable descriptions of what the transaction does), and wallet providers integrating Ledger’s SDK to pass that information securely to the device. It requires cooperation across the ecosystem to ensure clear signing becomes a consistent standard everywhere and not just within Ledger’s native environment​.

Generic Parser & ERC-7730 V2

Clear Signing wasn’t always this easy to use everywhere. In 2025, Ledger launched the Generic Parser, a smart new engine that automatically reads the metadata any dApp submits. This removed the old requirement for custom plugins on every single app, slashed the work for developers, and made Clear Signing available at a much larger scale across the ecosystem.

Then, in April 2026, the standard itself took the next big step forward with ERC-7730 Version 2. The main goal of V2 was to make adoption dramatically simpler and more scalable for any wallet or dApp builder, while also adding better flexibility, true cross-chain support, stronger privacy controls, and easier integration for both hardware and software wallets.

Through its Clear Signing Initiative, Ledger drove a broad community-driven effort that gained strong support from key players including the Ethereum Foundation, WalletConnect, Fireblocks, Sourcify, Trezor, and Cyfrin. 

To ensure long-term neutrality, trust, and a continued focus on security across the entire ecosystem, governance of the ERC-7730 standard has officially transitioned to the Ethereum Foundation.

Clear Signing on Ledger Wallet vs Other Ecosystems

Clear signing inside Ledger Wallet is seamless and straightforward because Ledger controls the entire environment; it can handle how transaction data is parsed, displayed, and approved directly on its secure screen. 

However, Clear Signing outside of Ledger Wallet, like when using third-party dApps or wallets, depends on dApp developers providing the right metadata and wallet providers integrating support for the ERC-7730 V2 standard. 

To get the full benefits and maximum security, always choose Ledger Wallet’s integrated third-party services and make use of its direct dApp connectivity, as these are currently the only places where Clear Signing works automatically and reliably.

The Challenge: Clear Signing Adoption Still Needs Expansion 

Even with the major advances of ERC-7730 V2 and the Generic Parser, Clear Signing is still not available everywhere. Many users continue to interact with third-party wallets and dApps that have not yet implemented the standard, which means they are still asked to blind sign those transactions.

This adoption gap remains the main challenge today. While the technology is now mature and open to everyone, full transparency across the entire ecosystem will only be achieved when more wallets and dApps actively support it. 

Ledger continues to drive this progress through the Clear Signing Alliance and open tools, but users get the strongest protection today by staying within Ledger Wallet’s integrated apps or using direct dApp connectivity.

The Solution: Building in the Open with Ecosystem Stakeholders 

Ledger has taken active steps to make the clear signing standard universal. 

Moreover, to maintain the integrity and reliability of the metadata that’s important for clear signing, Ledger has also proposed a transparent governance framework. This involves a public GitHub repository managed by Ledger, with contributions and reviews from the broader community to ensure accuracy and trustworthiness. 
To further grow adoption and implementation of clear signing, Ledger provides developers with accessible tools and resources.

An example is the ERC-7730 JSON Builder, an open-source tool that enables developers to easily create and visualize compliant JSON files for clear signing. This tool simplifies the process of crafting and validating metadata, allowing developers to preview how transaction details will appear on Ledger signers.

The Evolution of ERC-7730

In 2025, Ledger released the Generic Parser, which removed the need for custom plugins and enabled Clear Signing at scale. The following year, in April 2026, the standard evolved to ERC-7730 V2, bringing greater flexibility, cross-chain compatibility, and smoother integration for both hardware and software wallets.

To ensure long-term neutrality and community ownership, governance of the ERC-7730 standard has officially transitioned to the Ethereum Foundation. This shift, supported by the Clear Signing Alliance, allows the entire ecosystem to move forward together while keeping the standard truly open and permissionless.

While clear signing markedly improves transaction transparency, Ledger acknowledges that it functions best as part of a multi-layered security strategy. Complementary tools, such as Web3 firewalls and transaction simulations, are also important in identifying and mitigating potential threats.
