Snapy Rescue is a fork of superdarkbit/nano-bip32-ed25519. It checks the balance of every address associated with the 24 word seed from beta.snapy.io.
beta.snapy.io's wallet backup looks something like this:
{
"seed": "ring sunny close flash twenty ... ... ...",
"extendedPublicKey": "eee0e4d94509b...",
"walletId": ...,
"status": "success"
}
Copy the 24 words to your clipboard.
Run this repo locally or go to https://alemonfox.github.io/Snapy-Rescue/ and enter your seed phrase. If needed, change the amount of indexes to search.
Click Rescue Me to start checking account balances. Accounts with funds will be shown in green, accounts without funds will be red. Note: balances are fetched from api.nanos.cc.
When you find an account with funds, copy the private key to your clipboard. Then, visit nault.cc. A popular web-based Nano wallet. On the sidebar, click settings > configure new wallet. Then click on more options. After that, select import expanded private key and paste your private key.
You have now succesfully recovered your lost Nano's. Make sure to send everything to a wallet you own.
