The scan → review → APPROVE → SCAN TO APPROVE → DONE round trip is the same for every chain (see Signing a transaction). Only the fields on the ERA LENS review pages change. Whatever the chain, the amount, the recipient and the fee on ERA must match what you typed in the software wallet; if anything differs, tap the back chevron and do not approve. All examples use the wallet imported from abandon × 11 about.

Steps

Solana

  1. Create the transfer in your Solana wallet (for example Solflare) and scan its QR code with ERA.

Note: A Solana token transfer whose token ERA does not know shows the amount as "TOKEN" with a warning instead of the token name. Check the token in your software wallet before approving.

  1. Check Type, Amount, From and To.

TON and Cardano

Done

The SCAN TO APPROVE page closes when you tap DONE. The software wallet shows the transaction as sent to the network.

Trouble?

  • "INVALID REQUEST" appears → the request is for a chain ERA does not support, or it was built for a different wallet than the one you opened. Re-link the software wallet (see Link a software wallet) and try again.

  • "FIND YOUR WALLET" appears (Quick Sign) → pick the wallet with SELECT WALLET, or enter its passphrase with PASSPHRASE.

  • The review says "Unknown transaction" or you see BLIND SIGNING → ERA could not decode the request in full. See Warnings explained.
