How to send blind signed transactions?

If you want to use Ledger to sign all possible transactions on Partisia Blockchain, you need to enable blind signing on your device. This guide will teach you how to enable blind signing on your ledger device and how to do an ETH token transfer to another address on PBC with a blind signed transaction.

  1. Go to settings on your Ledger device enabling-blindsigning(1)-settings.png

  2. Default for Ledger is that blind signing is disabled. enabling-blindsigning(2)-default-not-enabled.png

  3. To enable blind signing click on the right button for enabling blind signing on the Ledger device. enabling-blindsigning(3)-enabled.jpg.png

This setting update changes how Ledger signs transactions on Partisia Blockchain. The following steps shows how a blind signed transaction looks like.

  1. After signing into browser with the Ledger device, we go to the ETH token contract where you can transfer ETH tokens. You need to fill out the receiving address and the amount of ETH tokens you want to send to another addres on Partisia Blockchain.

    Remember the amount of ETH tokens needs to have 18 decimals behind, e.g. if you want to transfer 10 ETH BYOC Tokens you would type: 10000000000000000000 in the transfer action. blindsign(1)-transfer-eth.png

  2. After sending the transaction to transfer tokens, you can see that the Browser waits for approval on the Ledger interact(2)-waiting for approval.png

  3. We now need to review the transaction on the Ledger blindsign(2)-transaction.png

  4. Ledger gives a warning on the device because of the blind signing. Ledger asks if you trust the content of the RPC sent on chain. blindsign(3)-warning.png

  5. In this review stage of using the ledger we need to verify that it is the right contract we are using. Its always important to rigorously review that the available information is correct when blind signing a transaction with Ledger. blindsign(4)-contract.png

  6. We need to accept the fee payment blindsign(5)-fee.png

  7. If you want to approve after the review you should click on Approve on the device. Alternatively you should click Reject. interact(7)-approve.jpg

  8. After approval, you can see that the Browser finishes the transaction and the transfer is complete. interact(9)-sending transaction.png
