Hey @adityapk00 I’m getting a few errors:

I had an older version of ZecWallet lite 1.1.6 sitting around which gave this error when I tried to use it:

`Error Initializing Lightclient Error: transport error: error trying to connect: invalid certificate: CertExpired`

Which I figured was because it was so out of date, so I updated it to 1.7.8 and it shows funds just fine but when I try to send it errors with:

`Error: SendResponse { error_code: -26, error_message: "18: bad-txns-sapling-duplicate-nullifier" }`

Any ideas what I did wrong?

Nevermind, I was able to fix this error by performing a -rescan . All is well 🙂
