 Confirming transactions with the ledger device requires a bit more effort than with a web or mobile wallet. When confirming the transaction, the ledger needs to be unlocked and the NEAR app must be open. You need to click through the transaction content and sign. Applications on BOS may time out while waiting for the transaction to confirm, and assume there's an error, while you are just in the process of clicking through the confirmation of the transaction on your ledger device.

 Ledger devices have software installed to support its operations. There is an operating system, and there are apps for different blockchain. You need to make sure that the operating system and NEAR app is installed and up to date, otherwise you may get unexpected results. Consult with the documentation of your ledger device to make sure that it is updated.
 
 Also make sure to navigate to the web4 version of your treasury, and that you are not already connected with another wallet. The direct ledger device support, described below, is only available through URLs on the form `https://<your-treasury-instance-name>.near.page`, and not through the `near.social` or `dev.near.page gateways`.

 When connecting a wallet, you may choose to use a ledger device directly.

+## Known limitations
 
 The treasury app assumes a transaction to complete within some time frame, and may display a message that something went wrong if the transaction does not complete within that time. You may still be in the process of confirming the transaction on your ledger, while you see a toast with the error message on the screen. If this happens, you may still proceed and confirm. The transaction will be processed.
 
 Ledger devices have limitations in transaction size. The treasury app may send large payloads, such as when the configuration of the DAO is updated. If this payload is too big, then signing a transaction using ledger may fail, and you may need to use another wallet for performing the action.
