Every SOLbin Tool Is Now Embeddable: Multi-Send, Rent Reclaim, Burner, Dust Sweep & AI Audit
The Widget Catalog Just Went From One to Six
When we shipped the SOLbin swap widget, the idea was simple: if someone is reading about your token, they shouldn't have to leave your page to trade it.
The same logic applies to every other wallet chore. Someone reading your airdrop announcement shouldn't have to open a second app to claim. Someone checking their holdings shouldn't have to hunt for a tool to clean up the dust that's been sitting in their wallet for a year.
So we made all six SOLbin tools embeddable. Each one now has its own bare embed route, its own configuration panel, and the same one-line HTML install.
| Tool | Embed route | What your visitors get |
| --- | --- | --- |
| Swap Widget | /embed/swap | Jupiter-routed Solana swaps with any token pre-selected |
| Multi-Send Engine | /embed/multi-send | Batch transfers across Solana, BNB Chain and Bitcoin |
| Rent Reclamation | /embed/rent | Empty SPL accounts closed, locked SOL rent returned |
| Token Incinerator | /embed/burn | Dust and spam tokens burned, accounts closed, rent reclaimed |
| Dust Aggregation | /embed/utxo | Unspendable Bitcoin dust UTXOs swept into one output |
| Wallet Auditor | /embed/audit | AI health scan: reclaimable rent, dust balances, spam tokens |
Every one of them installs the same way:

What Each Widget Actually Does
Multi-Send Engine — batch payments without the batch grind
Paying 40 contributors, airdropping to 200 community wallets, distributing rewards after a snapshot — the Multi-Send engine takes a list of address, amount pairs and dispatches the whole batch from one screen. It runs on Solana, BNB Chain and Bitcoin, and it validates every address before anything is signed.
Large Solana batches are the interesting part. A Solana transaction is capped at 1232 bytes, so the engine automatically splits a big list into as many transactions as it needs and streams them one after another — with live progress per batch. You paste 500 recipients, not five separate batches.
Rent Reclamation — get the SOL back out of empty accounts
Every SPL token account you ever opened holds about 0.00204 SOL in rent-exempt deposit. Close the account and that SOL comes back to you. Most wallets never make it that easy, so the rent just sits there — thousands of accounts deep in an active trader's wallet.
This widget scans any Solana address, lists every empty and dust account, and closes the selected ones in a single transaction with the rent returned to the owner.
Token Incinerator — burn the junk, reclaim what's under it
Spam tokens, failed experiments, projects that rugged before you could sell. Burning an SPL balance also closes its token account, so a cleanup pass on the incinerator returns the rent deposits along with it. It works across all three networks, and it is the fastest way to make a portfolio readable again.
Dust Aggregation — make tiny Bitcoin UTXOs spendable
Bitcoin dust is a special kind of annoying: UTXOs so small that spending them costs more in fees than they're worth. They sit in the wallet forever, inflating the input count on every transaction you actually want to send. This widget finds them and consolidates the lot into a single output, so the balance becomes usable again.
Wallet Auditor — the safety check your visitors run before they trade
The auditor reads the live on-chain account set for any Solana wallet — not a guess, not a cached number — and reports what's really in there: empty accounts with reclaimable rent, dust balances, active holdings, and spam-token risk flags. The findings are emailed to the signed-in user so they can act on them later.
For a token dashboard or a community site, it's the widget you put next to a contract address: paste any wallet, see what's inside it before you touch it.
Swap Widget — the original, unchanged
Jupiter-routed Solana swaps, any token pre-selected through a deep link, signed in the visitor's own browser. If you want the full breakdown, it has its own post.
Deep-Link the Form, Not Just the Widget
The Multi-Send and Auditor widgets accept query parameters, so a page can open with the tool already filled in — no typing, no friction, no support tickets about which address goes where.
| Parameter | Tool | Purpose |
| --- | --- | --- |
| network | Multi-Send | solana, bnb or btc |
| to | Multi-Send | Pre-fills a recipient address |
| amount | Multi-Send | Amount for the pre-filled recipient |
| token | Multi-Send / Swap | SPL or BEP-20 contract; for swaps, the buy token |
| address | Auditor | Solana wallet address to scan on load |
An airdrop page, for example, can open the engine already pointed at the right chain with the first recipient loaded:

Who Signs What
The widgets are self-custody end to end. Visitors connect Phantom, Trust Wallet or a SOLbin wallet, and every transaction is signed in their own browser. Your site never touches keys or funds, and you never take on custody liability.
Two behaviours to know before you install:
- The swap widget needs no sign-in at all. A visitor connects a wallet and swaps.
- Tools that broadcast a transaction — multi-send, burner, rent reclaim, dust sweep — and the auditor run through SOLbin's security gate, which signs every outbound action against a signed-in user. Those widgets show a slim sign-in bar when the visitor doesn't have a session, and return them to the exact same widget afterwards, so nothing is lost in the redirect.
That gate is the same infrastructure that keeps sends warning-free in Phantom: server-authoritative fee vaults, balance checks, value caps, replay-protected nonces. Embedding it means your users inherit it.
A Few Ways Partners Are Using This
- Token dashboards: swap widget plus auditor, so holders can trade and check safety without leaving the page.
- Airdrop and distribution pages: the Multi-Send engine deep-linked with the campaign's chain, token and first recipient.
- Wallet cleanup portals: rent reclamation, incinerator and dust aggregation side by side — reclaim SOL and BTC in one visit.
- Community sites and launch pages: the rent and burn widgets as the "free money" hook that gets people to open the tool at all.
Grab the Code
Everything is on the public developers page — no account needed:
- Pick a tool from the catalog.
- Set its parameters (network, recipient, amount, token, wallet address).
- Choose your width and height.
- Copy the generated iframe tag.
The page renders a live preview of the exact widget you configured, directly on the page, so you can see what your visitors will see before you paste anything into production. The "Powered by SOLbin" watermark links back to the app and stays visible in every embed — it's the only thing we ask in return for the tooling.
The same self-custody guarantee applies across the whole set: your site hosts the interface, your visitors hold the keys, and SOLbin does the plumbing.
