#COLDCARD Firmware Update
# Shared Mk4 & Q
New Features:
📳 PushTX: once enabled with a service provider's URL, you can tap the COLDCARD and your phone will open a webpage that transmits your freshly-signed transaction onto the blockchain. See Settings > NFC Push Tx to enable and select service provider, or your own webpage. More at https://pushtx.org . You can also use this to broadcast any transaction found on the MicroSD card (See Tools > NFC Tools > Push Transaction).
🕵️♂️ Transaction Output Explorer: allows viewing all output details for larger txn (10+ output, 20+ change) before signing. Offered for large transactions only because we are already showing all the details for typical transactions.
🏷️ Setting to enable always showing XFP as first item in home menu.
Enhancement:
⏫ When signing, show sum of outgoing value at top. Always show number of inputs/outputs and total change value.
⏫ Add Sign PSBT shortcut to NFC Tools menu
⏫ Stricter p2sh-p2wpkh validation checks.
⏫ Show master XFP of BIP-85 derived wallet in story before activation. Only words and extended private key cases.
⏫ Add Theya option to Export Wallet
⏫ Mention the need to remove old duress wallets before locking down temporary seed.
Bugfix:
👨🔧 Fix PSBTv2 PSBT_GLOBAL_TX_MODIFIABLE parsing.
👨🔧 Decrypting Tapsigner backup failed even for correct key.
👨🔧 Clear any pending keystrokes before PSBT approval screen.
👨🔧 Display max 20 change outputs in when signing, and max 10 of largest outputs, and offer the Transaction Output Explorer if more to be seen.
👨🔧 Calculate progress bar correctly in Address Explorer after first page.
👨🔧 Search also Wrapped Segwit single sig addresses if P2SH address provided, not just multisig (multisig has precedence for P2SH addresses)
👨🔧 Address search would not find addresses for non-zero account numbers that had been exported but not yet seen in a PSBT.
## Mk4 Specific Changes 5.3.2 - 2024-06-26
👨🔧 Displaying change address in Address Explorer fails if NFC and Vdisk not enabled.
## Q Specific Changes 1.2.2Q - 2024-06-26
⏫ Coldcard multisg export/import format detected in Scan Any QR Code.
⏫ Support newer-version QR scanner modules.
👨🔧 Exporting BIP-85 derived entropy via NFC was offered even when NFC disabled, leading to a Yikes error.
