Ledger Proof of Ownership
Prove ownership of your Pocket account to migrate to the new chain
Browser Not Supported for USB
Direct Ledger connection requires WebHID (Chrome, Edge, or Opera). However, mnemonic recovery works in any browser — scroll down to use it.
Secure Connection Required
This tool requires HTTPS. WebHID and cryptographic verification will not work over an insecure HTTP connection.
Using proxy: /speculos (proxied via serve.py to localhost:5005).
Or enter a direct URL like http://localhost:5005
Demo mode generates a random Ed25519 keypair in the browser. Proofs from demo mode should not be used for actual migration.
Path: 44'/635'/0'/0/0 — if your address doesn't match, try the other derivation path.

Security Warning
- Your mnemonic is the master key to all your funds. Entering it in a browser carries risk.
- Disconnect from the internet before entering your mnemonic (this page works offline).
- Use a private/incognito window and close it immediately after.
- JavaScript cannot guarantee memory is fully erased — inputs are cleared after derivation, but traces may remain in browser memory.
- Only use this if you cannot install the Pocket Ledger app (it has been delisted from Ledger Live).
Instructions:
Option A — Ledger USB (recommended)
- Connect your Ledger device via USB
- Unlock your Ledger and open the Pocket app
- In the Pocket app settings, enable Blind Signing
- Click "Connect Ledger" and select your device
- Click "Prove Ownership" to sign a challenge message
- Approve the blind sign request on your Ledger device
- Export the proof JSON file
Option B — Mnemonic Recovery
- If the Pocket Ledger app is unavailable, scroll down and click "Recover with Mnemonic"
- Disconnect from the internet before entering your recovery phrase
- Enter your 24-word mnemonic (and passphrase if you set one)
- Click "Derive Key & Prove Ownership" — your key is derived in-browser
- Export the proof JSON file
Finding Your Address
If the generated address doesn't match your known POKT address:
- Try Standard path at index 0 first
- If no match, switch to Extended path and re-derive
- If still no match, try incrementing the account index (1, 2, 3...)
Mnemonic recovery requires re-entering your phrase each time you change the path or index.
Note: Mnemonic recovery works in any modern browser. WebHID (Chrome/Edge) is only needed for direct Ledger connection.
