A file browser for
the things people own onchain.

Enter a wallet address or a name like snowfro.eth. Find3r shows its apps, artworks, and files in folders you can explore. You can look inside anyone’s collection. No sign-in or wallet connection needed.

Looking at a wallet doesn’t give Find3r access to it. You don’t need to approve a transaction, share a password, or prove that the wallet is yours.

Start with an address

1. Paste an address, a .eth name, a collection’s contract address, or a Find3r app link into Go to.
2. Leave Network on All chains, or choose Ethereum, Base, Arbitrum, or Base Sepolia. This checks the address you entered, not other people’s wallets.
3. Choose Apps, Art Blocks, or ABX to see that part of the collection.
4. Open something that catches your eye. Use Add address to keep a folder handy.

Simple mode is the default: click an app and its start page opens. Explorer mode lets you look at the files inside and choose older versions. You can switch between a list and icons, sort items, and use the back button or folder trail to move around.

A collection or app belongs to one network, so its network is shown while you’re inside it. Go back to the address or Home to choose a different network. Shared links keep the selected network. Apps from different networks have their own labels.

Saved addresses and connection settings stay in your browser. If you open Find3r inside another app or on a shared BAMFS website, some settings only last for that visit.

What’s in the folders?

• Apps: websites and files published with BAMFS on Base or Base Sepolia. Their files are read from the blockchain.
• Art Blocks: project folders containing artworks. Open a piece to see its image and details, then choose Live view or a full-screen image when available.
• ABX: items grouped by collection, with images, details, and live views when the collection provides them.

This is a growing set of supported collections, rather than a complete list of every NFT. Wallet discovery uses the collections known to the public readers. A collection contract or specific artwork can also be read directly, even when the ABX directory hasn’t listed it. Direct connections currently cover Ethereum, Base, Arbitrum, and Base Sepolia.

Wallets show Apps, Art Blocks, and ABX folders when supported holdings are found. Empty categories are hidden after a successful check; a failed check stays available to retry. Use the address in the breadcrumb trail above the files to go back and choose another folder. Large collections use small pages. Search Art Blocks and ABX for a project or artist, or search for a token number inside a collection. Next and Previous move through the results. Apps search and sorting apply to the page you’re viewing.

Collections, artwork links, and sharing

Paste a collection’s contract address to go straight to its contents. Art Blocks collections open into projects; BAMFS collections open into apps; ABX and other supported NFT collections show artworks. They don’t show wallet category folders. View holdings separately shows what the contract address owns.

You can paste an OpenSea artwork link too. Find3r uses the network, contract, and token number from the link to open the artwork here. Copy link shares a folder or selected item; Copy artwork link shares the piece you’re viewing. These links don’t require your saved addresses or settings.

Some collections don’t provide a complete list of their artworks. Find3r explains that and offers Open an artwork by number. Enter its token number, such as 0. An unrecognized contract is shown as a contract rather than being mistaken for a wallet. If the address exists on several networks, choose which one to browse.

Artwork details can come from the blockchain, IPFS, Arweave, or a website. The image and live view may use a different source. More about this piece shows those sources when Find3r reads the token directly. Storage locations aren’t separate collection types.

Choose how apps load

An app opens in a new tab. Find3r checks that its files match the published version before using them. In Settings → Opening apps, choose:

• Load as needed — the default. Find3r loads the page and the files it needs to get started. Other pages and files load as you use them. This usually opens faster, with a possible short wait later.
• Download everything first — Find3r gets the whole app ready before opening it. The first wait is longer, but the rest of that app’s published files are ready for the visit.

Both choices use the same published files and the same checks. Recent copies can be reused on your device for up to one day, so reopening is often faster. Settings → Clear local copies removes Find3r’s saved copies. An app’s own outside services still need a working connection.

Choose Open full screen to open a fresh view of the same published app in another tab, without the Find3r header or border. It fills the space below your browser’s own toolbar. Your original tab stays open; close the new tab when you’re done. Changes you made inside the original app aren’t copied into the new view.

Apps open in a protected view so they can’t read Find3r’s saved connection keys or folders. This first version doesn’t pass your wallet into that view or keep an app’s own saved state. Apps that need those features, or other browser features this viewer doesn’t support, may work better when you download and open a separate copy.

What is an RPC, and do I need one?

An RPC is a connection that lets an app read the blockchain. The name sounds technical; using Find3r doesn’t have to be.

• On find3r.app: Find3r covers the browsing connection. There’s nothing to set up.
• On other copies: free public connections are included for Ethereum, Base, Arbitrum, and Base Sepolia. Start browsing right away.
• If the public connection is slow or busy: open Settings, expand Advanced connection settings, and paste your own provider’s RPC URL for the network you’re using. Clear that field to use the default again.

Your own URL takes priority over the default. The connection can be changed without changing the app’s onchain address or files. On a shared BAMFS website, private connection fields are disabled; use Find3r on its own domain or your computer to save them.

A copy of Find3r opened inside Find3r starts with its own public connection. Its custom settings and folders last for that visit. An app you open can also make requests using connections built into that app; Find3r’s sponsored connection doesn’t automatically cover those requests.

Which version opens?

Opening an app normally selects its latest published version. BAMFS records that choice on the blockchain. If there’s an index.html or index.htm start page, Find3r opens it for you. Otherwise, you can browse the files.

A link to a specific version keeps opening that version. Once an app opens, Find3r keeps its file reads on that same version so an update won’t change files halfway through your visit. Open it again to pick up the latest publication. Explorer mode lets you choose an older version.

What lives onchain?

Find3r’s website files are published on BAMFS. The find3r.app address gives ordinary browsers a convenient way to reach them. A small Cloudflare Worker reads those files from the blockchain and keeps copies for faster delivery.

The BAMFS apps you browse work the same way: their published files can be read without the original creator’s website or BAMFS’s website. The domain, gateway, and RPC provider are replaceable ways to reach those files.

Some parts still use outside services. Art Blocks and ABX indexes help Find3r find owned artworks. Art Blocks previews and some ABX previews use their hosted services. Other artwork details are read from the collection contract and any storage address it provides. Individual apps or artworks may use outside images, libraries, or APIs too. Storing the website files onchain doesn’t make every service it uses permanent.

The promise is that someone with access to the chain and compatible software can recover the published files. It depends on the chain remaining available, its data being readable, and the app’s required outside dependencies being available or included with it.

Keep a copy, or ask your agent to help

Download file keeps the selected original file. Download app keeps the app’s complete published folder as a ZIP. These downloads preserve the original files.

Open independently gives you a prompt for your coding agent. It appears while browsing a BAMFS app or its files, and includes where the app lives and which version to read, so the agent can retrieve it using a connection you choose and help open it on your computer.

For supported BAMFS apps, the included recovery tool checks and reconstructs the complete folder directly from the chain. Artwork pages offer images, details, and live views instead. The technical agent guide separately explains how to investigate Art Blocks and ABX content and its outside dependencies.

Use Find3r without find3r.app

You can recover Find3r’s published files and run your own copy on your computer or a static website host. Public connections are included, and you can replace them in Settings. You don’t need a Find3r account or application server.

Opening a recovered copy through a local web server works more reliably than double-clicking its HTML file. Your agent can handle that step. Keep unfamiliar downloaded apps separate from places where you store private connection keys.

Give an onchain app a normal web address

Put this app online appears when you select or browse a BAMFS app. It fills in the selected app’s link and prepares a small Cloudflare Worker for a compatible BAMFS app. Think of it as a front door: visitors use a normal website address, and the Worker gets the app’s files from the chain.

1. Check the filled-in app link and choose whether to follow updates or keep a specific version. A selected app starts with “follow updates”; when you’re browsing a particular version, that version is selected instead.
2. Copy the prepared code into a Hello World Worker in your own Cloudflare account and deploy it.
3. Add the connection URL under Secrets with the name RPC_URL. Then use the Worker’s web address or connect your own domain.

Your website files stay on BAMFS. You upload the small gateway code to Cloudflare. Find3r prepares it; it doesn’t deploy into your account automatically.

Follow updates keeps looking for the latest version of the same BAMFS app, so you can publish a new revision without editing the pointer. A move to a different token or contract needs a new pointer. Choose a specific version when you want a gateway that always serves the same copy.
