Tools

Six tools from the BSV ecosystem, what each is for, and how they fit together when you design, build, test and support a BSV product.

This guide tells you what to design. These six tools are where you go to try it: one to use BSV apps with, one to build a working one in an afternoon, two to learn from, one to see what already exists, and one for the day a user's old wallet is gone.

BSV Browserbrowser.bsvb.techA free browser with a wallet and identity built in. Sign in with a tap and pay cents instead of subscribing, on Mac, Windows, iPhone and Android.
create-bsv-appcreatebsvapp.comA starter kit that builds a working React and Express app with wallet sign-in already connected, from one command or one prompt to an AI assistant.
Beersybeersy.devBRCs are the numbered standards that BSV apps and wallets follow, such as how an app asks a wallet to pay. Beersy explains all 228 in plain English and shows you the few to read first.
BSV Radarbsvradar.comA community directory of apps built on BSV, from wallets and games to exchanges and developer tools, with upvotes, ratings, reviews and filters by what each app can do.
Derivation PathPreviewderivationpath.comFinds and moves BSV left in wallets that no longer work, such as Centbee, RockWallet, MoneyButton and Twetch, from their recovery words.
Higher Learninghub.bsvblockchain.orgBSV Academy's free courses, arranged by audience: developers, business leaders, lawyers, miners, academics, executives and ICT students, with certificates through 360Learning.

How they fit together

They are separate projects, built by different people, but they line up with the work of making a product:

Learn the ground. Higher Learning for the concepts, then Beersy for the standards your product will touch.
See what exists. BSV Radar lists the apps people already use, with their reviews. Start every new product there.
Build the thing. create-bsv-app gives you a working app with wallet sign-in, so a design is tested against the real connection rather than a mock.
Use it as a user would. BSV Browser is the wallet and browser most people will meet your app in. Test every flow in it.
Plan for the worst day. Derivation Path is where to send somebody whose old wallet no longer works. Know it exists before you write your recovery screens.

Recommendation

Run every prototype in a real wallet before you show it to anybody. The prompts, the waits and the refusals are where BSV design succeeds or fails, and a mock has none of them.

BSV Browser

A web browser with a self-custodial wallet and an identity built in, for Mac, Windows, iPhone and Android. It is free and open source. Sites that support it let people sign in with a tap and pay a few cents for what they use, instead of creating an account or taking out a subscription.

For designers: it is the most likely place your web app will be used on a phone, because a phone browser cannot reach a wallet on its own. Test your connect prompt, your permission requests and your payment confirmations in it. See Web apps and native apps and Connecting a wallet.

create-bsv-app

A starter kit from the BSV Association. One command, npx create-bsv-app, or one prompt to an AI assistant gives you a React website and an Express server with wallet sign-in already working.

For designers and founders: the fastest way to put a design in front of a real wallet. A connect button, a sign-in prompt and a signed request, running in a browser, before anybody writes the rest of the product. See Code resources.

Beersy

All 228 BRC standards, each opening with the problem it solves in plain English. Search by number, title or author, or follow a guided path through the handful most products need.

For everyone: this guide cites BRCs on almost every page. When a page says "BRC-100" and you want to know what it actually requires, Beersy is the readable way in, and the proposal itself is one click further. See Reading the standards.

BSV Radar

A community directory of apps built on BSV: wallets, games, exchanges, marketplaces, developer tools and more, with upvotes, ratings, reviews and filters by what each app can do.

For researchers and founders: the quickest survey of the field. Use it to find the products your users already know, to read what people say about them, and to pick the wallets for a teardown. See Conducting research.

Derivation Path

Recovers BSV from the recovery words of wallets that no longer work or no longer exist, such as Centbee, RockWallet, MoneyButton and Twetch. The same words give different addresses under different derivation paths, so a new wallet can show an empty balance when the coins are still there. Derivation Path tries the paths those wallets used, shows what is on each address, and moves it to the user's current wallet or to any BSV address. It runs in the browser, and can be run on your own computer.

For wallet teams and support: when an import of old recovery words finds nothing, this is the next step to offer, not "your wallet is empty". See Legacy compatibility.

Higher Learning

BSV Academy's free courses, arranged by who you are: application developers, business leaders, lawyers, miners, academics, executives and ICT students. The courses are free to read; certificates are available through a separate 360Learning platform.

For a team: the place to send a colleague who needs the concepts before this guide makes sense, and the place to go deeper once it does. See Learning bootcamp.
