Our verdict on Crossmark
6.8/10Crossmark suits XRP Ledger users and developers who want a self-custodial wallet in a desktop browser and a straightforward SDK for web apps. Its main strength is a focused purpose with clear integration docs and a method set that covers single and bulk signing. The main caveat is transparency: audits, team details and fees are not published, and custom-network features are framed as goals. Check the official listing and use it with amounts you are comfortable holding in a browser wallet.

What is Crossmark?
Crossmark is a browser extension wallet built for the XRP Ledger. It lets users manage wallets and sign transactions from the desktop, and it gives web developers an SDK to connect their apps.
The project's mission page argues that the XRP community has mostly used a mobile-first wallet, while some applications and dashboards need a computer. Crossmark aims to fill that gap and to support custom networks, sidechains and a shared QR code structure.
The documentation site focuses on integration. It lists methods for signing in, signing, submitting and bulk operations, as well as events and session management. The team, audits and fee model are not covered in the material reviewed.
How Crossmark works
Crossmark is a browser extension that holds XRP Ledger keys in an encrypted keychain on the user's computer. When a web app needs a signature, it sends a request to the extension. The user reviews it and approves, and the signed transaction goes to the ledger.
For developers, the SDK wraps this flow. An app calls a sign-in method to get the active wallet address, then calls a sign-and-submit method with a transaction object such as a Payment with account, destination and amount in drops. The response includes the transaction hash so the app can confirm it.
The project says it is meant to fill a gap: XRP Ledger users have mostly relied on mobile-first wallets, and some web apps and dashboards suit a desktop browser better. It also aims to support custom networks and sidechains in time.

Key features
01
Browser extension wallet
Crossmark runs as a browser extension for managing XRP Ledger wallets and signing transactions on desktop.

03
Developer SDK
The @crossmarkio/sdk package lets web apps request sign-in, signing and submission through simple methods.
04
Sign and submit methods
The SDK has synchronous and asynchronous methods, including signAndSubmitAndWait, plus bulk sign and submit variants for several transactions at once.
05
Events and session handling
The docs list events such as user-change, network-change, response and signout, along with status checks like isConnected and isLocked.
06
Custom network ambitions

Pros and cons
What we like
- Fills a desktop gap for XRP Ledger users, where wallets have largely been mobile-first
- Self-custodial: the project says it does not collect private keys
- Clear developer docs with a short four-step integration example and an npm package
- Rich method set, including bulk signing and event listeners
- Source code is linked from the documentation, allowing technical review
Watch out for
- Browser-extension only per the published material, so there is no confirmed mobile wallet for on-the-go use
- Limited to the XRP Ledger, so it does not serve users who need multi-chain support
- Audit reports, team details and security disclosures are not published in the sources reviewed
- Fee, monetization and support details are not spelled out beyond a docs page title
- Browser extensions carry general risks such as phishing sites, malicious look-alike extensions and a compromised computer
- Custom-network and AMM features are described as plans, so it is unclear which are live
Crossmark fees
Crossmark does not publish a fee schedule in the material reviewed. The documentation does include a Monetization page, which is where developers or users should look for how the project earns money.
Transactions on the XRP Ledger carry the network's normal small transaction costs, which are set by the ledger and not by the wallet. Check the confirmation screen before signing to see the exact amount.
Is Crossmark safe?
Crossmark says it is self-custodial and never collects private keys or sensitive information. That reduces counterparty risk, but it puts responsibility on the user to protect recovery details and their device. The sources reviewed do not mention an independent audit, a bug bounty or past security incidents.
Browser extensions are exposed to phishing and fake look-alike listings, so check that the extension and docs come from the official project. Read every transaction prompt before approving. No regulatory or licensing details are published.

Who Crossmark is for
Crossmark is for XRP Ledger users who prefer managing assets from a desktop browser, and for developers building web apps that need a wallet-connect style signing flow on the ledger. It is less suited to people who need multi-chain support or an audited, institution-grade custody setup.
Crossmark FAQs
What is Crossmark?
Crossmark is a browser extension wallet for the XRP Ledger. It lets users manage wallets, send and receive assets and sign transactions from their browser, and it gives developers an SDK to connect web apps.
Is Crossmark self-custodial?
Crossmark describes itself as self-custodial and says it never collects users' private keys or sensitive information. The keys are held in an encrypted keychain on your own computer or browser, so you are responsible for backing them up.
Which blockchains does Crossmark support?
The project's documentation and mission page describe the XRP Ledger as its home network. They also mention future support for custom networks and sidechains, but those are presented as goals rather than confirmed features.
How do developers integrate Crossmark?
Developers install the npm package named @crossmarkio/sdk and call its methods to sign users in, request a signature, and submit the transaction. The documentation includes a four-step example: install, sign in, sign a payload and confirm the transaction hash.
Has Crossmark been audited?
The sources reviewed do not publish an audit report or a bug-bounty programme. The source code is described as available on GitHub, which lets technical users inspect it, but that is not a substitute for an independent audit.
Does Crossmark charge fees?
The documentation points to a Monetization page, but the fee details are not in the material reviewed. Normal XRP Ledger network fees apply to transactions regardless of the wallet.
