Bitcoin wallets and stacking!

Vendors

 

Do you maintain a Bitcoin wallet? Then help the growing Bitcoin community find it among all the others occupying this crowded space: Manage it on WalletMatrix.

WalletMatrix wants vendors to manage their own data. All that's needed is a GitHub account and a JSON file, then just push an update when you add new wallet features.

Benefits

By keeping wallet information updated, the Bitcoin community benefits by having a reliable source of wallet information to refer to, one that they know will not become stale.

Because WalletMatrix enjoys referrals from some popular Bitcoin resources; vendors and maintainers enjoy greater exposure to their projects. The same can be said of our REST API when developers connect their apps and render wallet data outside of WalletMatrix itself.

Vendors also benefit by shaping future WalletMatrix JSON schema iterations. Have your say about the features and options that should become searchable by the Bitcoin community.

FAQ

I'm keen, where do I sign up!?

If we haven't contacted you already, then all that's needed is for you to send an email to hello@dcentrica.com with the following information:

  • Your company or organisation name (Used to create your own, private data repository on GitHub)
  • Your wallet name
  • An email address and username
    • The address and username should be associated with an existing Github repo (preferably an official wallet repo owned by your organisation). We'll send an invite to this address for granting access to your new private, DCentrica owned GiHub data repository.
    • The address should also be associated with a public PGP key if you want users to be able to self-verify your data (recommended)

Once we hear from you, we'll setup your repository and respond with the repo URL and information about next steps.

Who are DCentrica?

DCentrica is the parent company of WalletMatrix, a small, bespoke software development shop based in New Zealand looking to specialise in software development using decentralised systems such as Bitcoin and IPFS.

How does it work?

We're assuming your developers already have a GitHub account, so we just need you to supply us with a GitHub username and email address and we'll add that user to a dedicated, private GitHub repository.

Developers maintain a JSON file and commit changes to the private repo each time new features should be added. WalletMatrix periodically consumes the GitHub data, validates and renders it on the website within the matrix itself and also via our REST API.

If you’re keen to take part, we’d love to hear from you: hello@dcentrica.com

What does the JSON file look like?

The file is named matrix.json and should validate against our version 2 JSON schema. Vendor data is automatically validated against the schema each time our automated import process runs. Validation failures are automatically detected and we're automatically notified.

We have two GitHub repos for our iOS and Android app, do these count as two separate wallets?

No.

We don't support multiple data repos for the same wallet. Instead we assume an iOS and Android app comprise the same (or very similar) features of the same wallet and therefore only a single instance of matrix.json should exist. In this case the matrix.json data file can be configured to contain Github references to both projects' repos too.

Why GIT?

  • You have developers!
  • Incorporate matrix.json creation and validation as part of your CI pipelines
  • No admin login required, which is a reduced attack vector, and less hassle for vendors

How do we validate our matrix.json against the schema?

VSCode users can configure their editors to validate their matrix.json file against our schema.

How does self-validation for users work?

Wallet vendors can optionally digitally sign their matrix.json file using PGP by exporting a detached signature file and naming it matrix.asc. Once pushed to GitHub, and when WalletMatrix discovers this file, an extra validation process occurs during the periodic import process.

If the signature is valid for the associated matrix.json file, then a “shield” icon becomes highlighted when your wallet appears in search results. Users can then select this in order to download the files and manually validate them using free and open source tools.

We updated matrix.json but forgot to update matrix.asc, what happens now?

Not much! But while this remains the case, the automated validation process will fail which will result in users seeing the corresponding “shield” icon displaying as "faded" (aka un-verified) for your wallet, when displayed in search results. This means that users will not be able to download your files in order to self-verify.

You should create a new matrix.asc file and push that to your GitHub repo as soon as possible, so it can be processed in the next import run.

We changed our company name and updated matrix.json, but self-verification breaks. What happened?

The automated PGP validation system relies on there being a match between the "organisation.name" JSON field, and the DCentrica github repo slug. Future iterations will likely rely on a UUID which of course is not subject to change.

In the interim, if you need to change your organisation name, just let us know with as much notice as you can, and we’ll sort that for you.

What does it cost?

Nothing for vendors, and it will always be free for platform visitors to view the data via a browser.

We welcome contributions from vendors who have the means to contribute and who may have benefited from their services being available on WalletMatrix. Email us to find out how: hello@dcentrica.com.

While Web API requests are initially free, we do plan on introducing a tiered access model, priced and paid in Satoshi, using The Lightning Network.

How do you avoid Wallet Scams?

In order to ensure a minimum level of quality and to avoid scam projects, there's a handful of criteria that wallets should meet. See our Listing Policy to find out more.

How are wallets in the Matrix sorted?

In order to avoid gamification of search results by sorting by last-updated date, search results are instead ordered alphabetically by wallet name.

How often is new Wallet data automatically updated?

Hourly.

We pushed some changes, but they haven't appeared for over an hour. What's up?

Assuming you can rule-out browser or proxy caches that are showing you stale data, then it's likely your matrix.json hasn't validated correctly against our schema. Double check that then commit your changes and push again.

Note: There is currently no automated alert for you when this happens (It's in our backlog though).

Can we help with anything?

You sure can!

How can the current version 2 schema be improved? What does the WalletMatrix JSON Schema v3 look like? The schema is used to validate incoming data from GitHub. Our ideas right now are centred around fine-grained data points for Lightning Network features such as the following, but your suggestions are welcome. Flick us an email: hello@dcentrica.com.
