You needERA device, an app that imports a multi-account QR (UR crypto-multi-accounts format)

The Multichain entry lets you choose which networks go into one link QR code. Use it for apps that accept a multi-account QR and are not listed by name on the ERA.

Steps

Part 1: On the ERA

  1. On the wallet screen, tap the settings icon (sliders) > Link. See Open the Link menu.

    Wallet settings list with the Link row, subtitle Connect to Wallet App.
    ERA: Wallet settings.
  2. On the wallet list, swipe up to the last page and tap Multichain.

    Last page of the wallet list with the single row Multichain, networks ETH, SOL, BTC and more.
    ERA: Wallet app list.

Note: Cardano, Stellar, XRP and TON are not offered in the Multichain list on purpose: their apps reject the generic multi-account code. Use VESPR, XRP Toolkit or Tonkeeper instead.

  1. On SELECT CHAINS, tap each network you want in the link, swiping up to see more (13 pages). A tick appears in each box you tap.

    Select chains over three pages: Bitcoin ticked on page 1, Ethereum ticked on page 2, and the last page with Zora and a CONTINUE button.
    ERA: Select chains.
  2. On the last page, tap CONTINUE. The tick in the header does the same from any page.

  3. On CONNECT Multichain, tap SHOW QR. The screen says: "Open wallet software that supports UR Crypto-MultiAccounts format for hardware wallet integration. Scan the QR code from the ERA Wallet screen."

    Connect Multichain instruction page with two steps and a SHOW QR button.
    ERA: Connect Multichain.
  4. QR FOR LINK appears and keeps changing: the keys are split over several codes that loop. Leave it on screen.

    Phone: Scan hardware wallet QR.

  2. Point the phone camera at the ERA screen and hold still until the app reports the import is complete. Scanning takes a few seconds because the code animates.

Done

The app shows the accounts for the networks you ticked, and the ERA is back on SETTINGS.

Trouble?

  • CONTINUE stays grey → no network is ticked yet. Tap at least one box.

  • The app rejects the code → it may not accept a multi-account QR. Try the app's own entry in the list, or Generic BTC / Generic ETH.

  • The app keeps scanning and never finishes → hold the phone still and let the animation loop twice. See Linking problems.
