hi backslash

I developed a dapp https://airdrop.ont.io/ .
use cyano signing the sc tx is successful, but when change to ledger, failed。

May you pay attention to this issue?

Hi,

unfortunately dApps can not use Ledger. It is not a problem of Cyano, rather the support of the Ledger application.

Most likely you won't be very successful asking for support in Ledger app, because Ledger/Trezor and other HW wallet producers don't like arbitrary transaction signing. It's against their security policy.

Thank you very much for your reply!

Cyano does work with the airdrop but not every time. It seems that it succeeds for some first time while others have reported it taking up to 10 attempts.
