Bunker
by NosisTech

Which of your coins show their lock?

Paste your public addresses. Bunker reads more than 100 networks, shows each lock that the world can see, and gives you a calm plan to hide what you can.

  • Runs on your device. Works with no internet connection.
  • Sends nothing. No wallet connection, no tracking, no cookies.
  • Blocks secrets. A seed phrase or private key is cleared at once.

Paste public addresses only. Never paste a seed phrase or private key into any website.

Your locks

Field guide

Where things stand on October 25, 2026
The math
Nobody has shown a break of the signatures that Bitcoin, Ethereum or Solana use. AI math is advancing fast, so it is time to prepare.
The debate
Security experts disagree on how soon a break can come. They agree that a rushed migration is dangerous. Use addresses that have never signed if it is easy, and move slowly.
Scams
False emails that look like Ledger and Trezor tell users to install a "quantum patch". Update firmware only in Ledger Live or Trezor Suite. Do not use a link in an email.
Fixes
Bitcoin BIP-360 is on test networks only. Ethereum has a post-quantum team and plans hash-based signatures. Zcash opened a new shielded pool, Ironwood, that supports quantum-recoverable notes. Sapling and Orchard funds must be moved there.
Why extra security now

The last lock on your coins is a math problem that nobody has solved. The early lock of the internet, RSA, had to grow to signatures of about 400 bytes because mathematicians found shortcuts. Your wallet signature is 64 bytes because nobody has found a shortcut for its math yet.

AI is advancing at an alarming rate. If machines find the shortcuts that people did not find, a lock that was safe for decades can become weak fast. Nothing is broken today. The goal is to be ready.

Your address is a sealed box with your lock inside. On most addresses, the world sees only a fingerprint of the box. When you receive coins, the box stays closed. When you sign anything, the box opens: a transaction, a token approval, an NFT listing, or a "sign in with wallet" message.

Open from day one: Solana, Bitcoin Taproot (bc1p), Lightning, Spark, Ark, Kaspa, Monero, Polkadot, Bittensor, Stellar, Algorand, NEAR, Hedera, Flow, MultiversX and Mina.

Do not hurry. A bad migration can lose more money than the risk that it avoids.

  • Keep savings on an address that has never signed anything.
  • For Bitcoin, use a new bc1q address, not bc1p.
  • Send a small test amount first. Examine each character of the address.
  • A "quantum migration tool" in your messages is a drainer. Do not type your seed phrase into a website.
Supported networks

The tool reads each format and checks its checksum if the format has one. A typo shows as a typo, not as a rating. Explorer links show only where the link format was checked against live explorer pages.

Words you will see
Public key (the lock)
Anyone can use it to check your signature. The risk is new math that finds the private key from the public key.
Private key and seed phrase (the key)
These move your coins. They stay in your hardware wallet. Nobody honest asks for them.
Hash (the fingerprint)
A one-way fingerprint. Nobody can rebuild the input from it. Most addresses are a hash of the public key, so they hide the lock.
Fresh address
An address that has received coins but has never sent or signed anything.
Taproot (bc1p)
A Bitcoin address type from 2021. Ordinals and Runes use it. It puts the public key in the address.
BIP-360 and P2MR
A proposed Bitcoin address type (bc1z). It shows only a fingerprint of the spending rules until you spend.
Drainer
A scam website, app or email that makes you sign something or type your seed phrase, and then empties your wallet.
Use Bunker with AI agents

Bunker has the same engine in three forms. All of them run on your own computer, offline.

  • This page, for people.
  • A command-line tool with JSON output: node cli/bunker.js --json addresses.txt
  • An MCP server for Claude, Cursor and other agents, with the tools scan_addresses and list_networks.

Agents can read /llms.txt and /networks.json on this site. Get the code and the setup steps on GitHub.

Accessibility

Bunker is built to follow the Web Content Accessibility Guidelines (WCAG) 2.2, Level AA. We test every release, and we fix every problem that we find or that you report.

How we check. Automated tests (axe-core) in English and Spanish, in light and dark mode, and checks by hand: keyboard only, 400% zoom and a narrow phone screen. A review with several screen readers is the next step. Last review: October 25, 2026.

What works. The full page works with a keyboard. Every control has a label. Focus is always visible. Results and messages are read aloud. The page follows your system settings for color, motion and text size.

Known limits. Screen readers read long addresses one character at a time. The plan is also available as plain text with Copy plan.

Tell us about a problem. Email info@nosistech.com or open an issue on GitHub. We answer within 5 working days. If a part of the page does not work for you, we will help you get the same result in another way.
