This guide is about designing BSV products: wallets, payments,
identity, keys and the screens around them. It is written for the
person drawing the interface rather than the person writing the node.

Throughout, **bitcoin** means BSV, the original protocol as described in
the 2008 white paper. Where a difference from another chain matters to a
design decision, the page says so explicitly.

## Getting started

Why BSV is different, the design principles, the visual language, and the software and hardware you design for.

- [Getting started](https://www.bitcoinsv.design/guide/getting-started/introduction/): What BSV is, the five things to know before drawing anything, and where to start if you design products, research them or found them.
- [The hard parts](https://www.bitcoinsv.design/guide/getting-started/the-hard-parts/): The problems that stay hard when you design a BSV product, each framed as the questions users ask and the decisions you have to make, before any answer.
- [Why BSV is different](https://www.bitcoinsv.design/guide/getting-started/why-bitcoin-is-unique/): The properties BSV shares with all bitcoin, the ones that come from its own choices, and the honest limits of both.
- [Why design for BSV](https://www.bitcoinsv.design/guide/getting-started/why-design-for-bitcoin/): What the work is actually like, which problems are genuinely open, and who it suits.
- [Design principles](https://www.bitcoinsv.design/guide/getting-started/principles/): Seven commitments this guide holds BSV products to, what each one costs, and the rules that follow from them.
- [Visual language](https://www.bitcoinsv.design/guide/getting-started/visual-language/): The bitcoin symbol, the satoshi, and the imagery BSV inherits: which pieces to use in a product, which to avoid, and why.
- [Technology primer](https://www.bitcoinsv.design/guide/getting-started/technology-primer/): Enough of how BSV works to make good design decisions, in the order the pieces actually depend on each other.
- [Software categories](https://www.bitcoinsv.design/guide/getting-started/software/): The kinds of BSV software that exist, what each is for, and which of them you are most likely to be designing.
- [Hardware categories](https://www.bitcoinsv.design/guide/getting-started/hardware/): The physical objects in a BSV product's picture, from a sheet of paper to a till, and which of them a designer actually has to account for.
- [Open design](https://www.bitcoinsv.design/guide/getting-started/open-design/): Designing in public: what changes about the process, what it costs, and how licensing actually works here.

## Designing BSV products

The design process: knowing your users, the usage life cycle, personal finance, accessibility and common flows.

- [Personal finance](https://www.bitcoinsv.design/guide/designing-products/personal-finance/): The money jobs people already have, which ones BSV suits and which it does not, and the wallet that fits each.
- [Spending, saving and delegating](https://www.bitcoinsv.design/guide/designing-products/spending-saving-delegating/): Three ways people relate to the money in a BSV product, why each screen should serve one of them, and the bridges to build between them.
- [Designing BSV products](https://www.bitcoinsv.design/guide/designing-products/introduction/): The design method, and the four places where designing for BSV changes the method rather than just the examples.
- [Getting to know your users](https://www.bitcoinsv.design/guide/designing-products/getting-to-know-your-users/): What moves people towards a BSV product, what stops them, and which barriers to design against first.
- [Common user flows](https://www.bitcoinsv.design/guide/designing-products/common-user-flows/): The flows nearly every BSV product needs, what each must get right, and the ones you do not need to build.
- [Usage life cycle](https://www.bitcoinsv.design/guide/designing-products/usage-life-cycle/): From never having heard of it to using it without thinking, what each stage needs, and where people actually drop out.
- [Interoperability](https://www.bitcoinsv.design/guide/designing-products/interoperability/): Letting people take their money, their identity and their data somewhere else, and why on BSV the connection standard does most of the work.
- [Accessibility](https://www.bitcoinsv.design/guide/designing-products/accessibility/): The accessibility work every product needs, and the handful of places where an irreversible payment raises the stakes.

## Patterns

What to design, by task: connecting a wallet, showing amounts, paying by handle, charging per use, letting an agent spend, tokens, data and conditions.

- [Patterns](https://www.bitcoinsv.design/guide/patterns/): What to design, by task: connecting and signing in, amounts and payments, errors, agents, tokens, stored data and spending conditions.
- [Connecting a wallet](https://www.bitcoinsv.design/guide/patterns/connecting-a-wallet/): How an app connects to a person's BSV wallet: what it can ask for, how little to ask for, and how the wallet knows who is asking.
- [Permissions and allowances](https://www.bitcoinsv.design/guide/patterns/permissions-and-allowances/): What an app can do after it connects: the permission prompt, spending allowances, the wallet's permissions dashboard, revoking, and the capabilities that stay off by default.
- [Signing in](https://www.bitcoinsv.design/guide/patterns/signing-in/): Signing somebody in with their wallet when there are no accounts or passwords: the first visit, returning visits, signing out, and asking for one fact from a Pass.
- [Paying by handle](https://www.bitcoinsv.design/guide/patterns/paying-by-handle/): Paying somebody by a readable name: how a handle becomes a payment, what to show before the confirm button, and the risk a readable name brings.
- [Amounts and units](https://www.bitcoinsv.design/guide/patterns/amounts-and-units/): How to show BSV amounts: satoshis as the unit, which figure leads, what to do about the missing symbol, and the rules that stop a number being misread.
- [Charging per use](https://www.bitcoinsv.design/guide/patterns/charging-per-use/): Charging a few satoshis many times: the patterns that work, the prompt problem, and how to show hundreds of payments without making somebody anxious.
- [Wrong-network payments](https://www.bitcoinsv.design/guide/patterns/wrong-network-payments/): Why a BSV address and a BTC legacy address are indistinguishable, what that costs a user, and the four defences in the order they are worth building.
- [Errors and failed payments](https://www.bitcoinsv.design/guide/patterns/errors-and-failed-payments/): The model for every failure in a BSV product: plain words first, whether money moved, what to do next, and the code underneath for support.
- [Letting an agent spend](https://www.bitcoinsv.design/guide/patterns/letting-an-agent-spend/): Software spending on somebody's behalf: what to grant it, how to bound it, and the review screen a person needs when they were not the one who decided.
- [Holding tokens](https://www.bitcoinsv.design/guide/patterns/holding-tokens/): What a token is on BSV, how one reaches a wallet, and the four things a product has to show before somebody can trust what they are holding.
- [Spending conditions](https://www.bitcoinsv.design/guide/patterns/spending-conditions/): Rules written into money about when and how it can be spent: what BSV supports, how to explain a lock nobody can undo, and why the setup is part of the backup.
- [Storing data on chain](https://www.bitcoinsv.design/guide/patterns/storing-data-on-chain/): Putting data on the chain: what it is good for, what permanence means for a consent screen, and the four things to settle before you write anything.
- [Web apps and native apps](https://www.bitcoinsv.design/guide/patterns/web-and-native-apps/): How a website, a phone app and a desktop app each reach a person's BSV wallet, and what changes for the connect prompt, the no-wallet case and who the wallet can say is asking.

## Daily spending wallet

A mobile wallet for everyday use: first use, connecting to apps, paying, receiving, contacts, activity, backup, security and settings.

- [Daily spending wallet](https://www.bitcoinsv.design/guide/daily-spending-wallet/): A reference design for a BSV wallet people use every day: what it is for, what it is deliberately not for, and the nine flows it is made of.
- [First use](https://www.bitcoinsv.design/guide/daily-spending-wallet/first-use/): From finding the app to holding money, without a wall of warnings: what to ask, what to defer, and when to ask for a backup.
- [Requesting](https://www.bitcoinsv.design/guide/daily-spending-wallet/requesting/): Asking to be paid on BSV: the handle, the QR code, the amount, and why there is no invoice to expire.
- [Receiving](https://www.bitcoinsv.design/guide/daily-spending-wallet/requesting/receiving/): What happens when money arrives, how the wallet knows, and the three cases that are not the happy path.
- [Sending](https://www.bitcoinsv.design/guide/daily-spending-wallet/sending/): Paying a person, a shop or an app on BSV, and the review screen that is the only chance to catch a mistake.
- [Send fees](https://www.bitcoinsv.design/guide/daily-spending-wallet/sending/send-fees/): Why a BSV wallet has no fee picker, what to show instead, and the one place a fee still deserves a line.
- [Activity](https://www.bitcoinsv.design/guide/daily-spending-wallet/activity/): What happened, including the hundreds of tiny app payments a BSV wallet has to show, grouped so the list stays readable.
- [Contacts](https://www.bitcoinsv.design/guide/daily-spending-wallet/contacts/): People and apps the user pays more than once. The feature that stops them typing handles, and the one that warns them when a key changes.
- [Security](https://www.bitcoinsv.design/guide/daily-spending-wallet/security/): Locking the app, approving payments, and managing what connected apps are allowed to do, which is where the real risk in a connected wallet lives.
- [Privacy](https://www.bitcoinsv.design/guide/daily-spending-wallet/privacy/): What a BSV wallet gets for free, what the user still controls, and the one leak that is a coin selection decision.

- [Automatic cloud backup](https://www.bitcoinsv.design/guide/daily-spending-wallet/backup-and-recovery/cloud-backup/): The wallet backup: the records half of a BSV backup, encrypted on the device, kept continuously, and the reason a restored wallet can find its money.
- [Backup and recovery](https://www.bitcoinsv.design/guide/daily-spending-wallet/backup-and-recovery/landing-page/): Why a BSV wallet backup has two parts, what each one restores, and how to design a flow that tells users the truth about it.

## Savings wallet

A wallet for larger amounts that never connects to apps, with multi-key protection and deliberate top-ups.

- [Savings wallet](https://www.bitcoinsv.design/guide/savings-wallet/): A wallet for money that moves rarely: several keys, no app connections, and deliberate top-ups to the wallet that does the spending.
- [Time-based recovery](https://www.bitcoinsv.design/guide/savings-wallet/time-based-recovery/): A recovery path that opens after a period of inactivity, how BSV builds it without CHECKLOCKTIMEVERIFY, and the maintenance that keeps it from firing by accident.

## Inheritance wallet

Long-term savings with a plan for passing funds on.

## Wallet patterns

Several wallets at once, one shared between people, and one that grows.

- [Wallet patterns](https://www.bitcoinsv.design/guide/wallet-patterns/): Three ways of structuring wallets that are not a wallet design in themselves: several at once, one shared between people, and one that grows.
- [Multiple wallets](https://www.bitcoinsv.design/guide/wallet-patterns/multiple-wallets/): Running everyday, savings and agent wallets side by side: how separate they need to be, and how to keep that from feeling like admin.
- [Shared wallet](https://www.bitcoinsv.design/guide/wallet-patterns/shared-wallet/): Money more than one person controls: how the approval rule is enforced by the script rather than by policy, and what that costs.
- [Upgradeable wallet](https://www.bitcoinsv.design/guide/wallet-patterns/upgradeable-wallet/): Start on one key, move to several when the balance justifies it, without the user having to understand key schemes on day one.

## Pay-per-use reader

A reading app that charges by the article: first visit, connecting, an allowance, the meter, receipts and refunds.

- [Pay-per-use reader](https://www.bitcoinsv.design/guide/pay-per-use-reader/): A reference design for a reading app that charges by the article, with no subscription and no account: who it is for, its three flows, and the patterns it applies.
- [First visit and connecting](https://www.bitcoinsv.design/guide/pay-per-use-reader/first-visit/): How The Satoshi Vision gets a new reader from a free front page to a first 20 sat article and an allowance, asking for each thing only when it is needed.
- [Reading and the meter](https://www.bitcoinsv.design/guide/pay-per-use-reader/reading/): How The Satoshi Vision charges inside an allowance without a prompt, shows the running total and a stop control on every paid article, and handles a used-up allowance and a failed payment.
- [Receipts, refunds and leaving](https://www.bitcoinsv.design/guide/pay-per-use-reader/receipts-and-leaving/): What Anna sees afterwards: grouped payments in her wallet, a receipt page in The Satoshi Vision, a refund paid as a new payment, a price change, and what the app shows once she revokes it.

## Connected web app

A ticketing site with no accounts: signing in with a wallet, proving an age with a Pass, buying, coming back and leaving.

- [Connected web app](https://www.bitcoinsv.design/guide/connected-web-app/): A reference design for a ticketing website with no accounts and no passwords: signing in with a wallet, proving an age with a Pass, buying a ticket, coming back and leaving.
- [Signing in](https://www.bitcoinsv.design/guide/connected-web-app/signing-in/): How Example Tickets signs Anna in with her wallet: one button for every visit, the wallet's prompt, what the site says it received, a returning visit with no prompt, and a second device.
- [Proving an age](https://www.bitcoinsv.design/guide/connected-web-app/proving-an-age/): How Example Tickets asks for proof that Anna is over 18 at checkout for an over-18 gig: one field from a Pass, the wallet's prompt, what happens when she has no Pass, and a refusal that is not an error.
- [Buying a ticket](https://www.bitcoinsv.design/guide/connected-web-app/buying-a-ticket/): How Anna buys a ticket on Example Tickets: the review screen, the wallet's payment prompt, the ticket arriving in her wallet as something she holds, and the ticket on the night.
- [Coming back and leaving](https://www.bitcoinsv.design/guide/connected-web-app/coming-back-and-leaving/): How Anna signs out of Example Tickets, disconnects it from her wallet, sees what the site keeps about her, and keeps her ticket when she leaves.

## Agent with a budget

An AI assistant that buys data for somebody: setting it up, its limits, approvals, the activity trail and stopping it.

- [Agent with a budget](https://www.bitcoinsv.design/guide/agent-with-a-budget/): A reference design for an AI research assistant that buys data and articles on somebody's behalf: its own wallet, four limits, approvals, the activity trail, and stopping it.
- [Setting it up](https://www.bitcoinsv.design/guide/agent-with-a-budget/setting-it-up/): Giving Scout its own wallet, choosing its four limits, funding it from Bitcoin SV Wallet, and the one review of the whole delegation before it starts.
- [While it works](https://www.bitcoinsv.design/guide/agent-with-a-budget/while-it-works/): What Scout does with nobody watching: paying inside its limits without prompts, asking Anna about anything outside them, reaching its budget, and handling a service that fails or asks for too much.
- [Reviewing what it did](https://www.bitcoinsv.design/guide/agent-with-a-budget/reviewing-what-it-did/): How Anna finds out what Scout spent while she was away: the daily summary, the activity trail by task and service, the record behind each purchase, and what to do when something looks wrong.
- [Stopping it](https://www.bitcoinsv.design/guide/agent-with-a-budget/stopping-it/): Pausing Scout at once, revoking its delegation, sending what is left back to Bitcoin SV Wallet, and what Scout tells Anna about the task it was in the middle of.

## Product and business

Business models small payments make possible, pricing, what to measure, growth that pays, custody as a product decision, and how much to say about BSV.

- [Product and business](https://www.bitcoinsv.design/guide/product/): The decisions a founder or product lead makes about a BSV product: how it earns, what it charges, what it measures, how it grows, who holds the money, and how much to say about the network.
- [Business models](https://www.bitcoinsv.design/guide/product/business-models/): The ways a BSV product can earn when a payment costs less than a penny: pay per use, metering, allowances, tipping, credit to try, unbundled subscriptions and models without advertising, with what each asks of the user.
- [Pricing](https://www.bitcoinsv.design/guide/product/pricing/): Setting prices for a BSV product: price in local currency and settle in satoshis, show the price before the action, round honestly, change prices without surprises, and refund with a new payment.
- [Measuring a product](https://www.bitcoinsv.design/guide/product/measuring-a-product/): The metrics that mean something for a BSV product, from a first payment as activation to recovery readiness and agent budgets, the vanity numbers to ignore, and how to measure without linking people's payments to who they are.
- [Growth that pays](https://www.bitcoinsv.design/guide/product/growth-that-pays/): Growing a BSV product by paying people directly: referral payouts that arrive instantly, paying for contributions, credit to try, shareable handles and payment links, and the fraud every reward attracts.
- [Custody as a product decision](https://www.bitcoinsv.design/guide/product/custody/): Who holds the keys in your product: the user's own wallet, the product holding funds, or an arrangement in between, compared as onboarding, support, recovery and responsibility trade-offs.
- [Talking about BSV](https://www.bitcoinsv.design/guide/product/talking-about-bsv/): How much of the network a product should show, when to name it as Bitcoin SV or BSV, how to write a store listing and a landing page, and the copy that loses people.
