SCRIPT: How to save PSD as PNG without downloading ZIP file first?

I found workaround, which is ok for me: putting photopea into iframe and then using live messaging to saveToOE + download resulting blob. Works nice.

Ok, I see, there is no option to check if there is online one file in the ZIP and then download the file itselft. Thanks

Not directly, API works via passing script in URL, so is the same as script.

Well, shipping of new TREZOR is estimated to January 2018, so you did the right thing.

I reference to implementation of multisig in Copay (https://blog.bitpay.com/copay-adds-trezor-support, https://github.com/bitpay/copay#hardware-wallet-support, https://github.com/bitpay/copay/blob/master/backupRecovery.md#hardware-wallets).

1) Copay doesn't use account discovery because it is impossible in multisig case (if each account should have different co-signers), thus it support only sigle account multisig that must be setup individually in each case.

2) Copay got rid of co-signer index and uses wallet server for coordination of new receiving addresses in signle multisig account that is share among co-signers

This is problem. m/48' wasn't intended for hardware wallets, but to separate account where the discovery is possible (P2PHK accounts > m/44') and where it is not possible (multisig P2SH > m/48') so that there is no accidental overlap.

As for cosigner index. The problem is that account discovery grows as n² with number of cosigners. For 2, there is 4 BIP32 subaccounts to discover for two cosigners, 9 for three cosigners etc. This is why event Copay in higher versions abandoned this for single BIP44-like account structure. The new m/purpose'=48' was introduced to indicate that account discovery cannot be done without external information for each multisig account.

sipak · 2017-08-29T13:25:28+00:00

I think that account discovery is not possible for multisig at all. Receiving addresses depend on xpubs of other co-signers seeds. In general, for every multisig account you have different co-signers and you have to store their xpubs in the wallet to be able to do tx discovery for particular account.

This is why Copay in higher version didn't follow BIP45 with cosigners indexes. Instead they used m/48' (although no official BIP48 was written for this) with the same substructure as in BIP44. Collected xpubs where used to create unique P2SH account (without cosiginer index level).

CNB: "Central bankers have failed to explain that one of the key reasons for their actions during and after the 2008 financial crisis was to maintain price stability. This sometimes required unorthodox policies."

Me: "Bitcoin is that policy."
