Description

BRA-Q322-3. Misleading Blockchain Names

Before rendering a blockchain name, Brave Wallet uses the reduceNetworkDisplayName function to reduce the network name.
Such a design decision leads to ambiguity for users and possible unintended transactions. For example, executing transaction on the main network instead of using test network. Users must hover over the blockchain name to be sure on which network they will be executing transactions.

Steps to Reproduce

1. Enable displaying test networks from Wallet setting
2. Unlock the desktop version of the Brave Wallet
3. Select Ropsten Testnet
4. Send ETH from one account to another
5. Notice that the network name is not fully displayed

Actual result:

Expected result:
