Support Metamask address QRs

[xAlisher]

User Story

As a Status app user, I want to be able to scan Metamask QR addresses, so I can send assets or save the address, if Status supports the network.

Description

Metamask stores addresses in QR codes with the following format: ethereum:0x38cf6E0Ba4C4530735616e1Ee7ff5FbCB726fBd2@0xa

ethereum: - prefix described in EIP-67 0xa - chain ID suffix described in EIP-155

Since Status addresses do not include these parts, we need to convert the data from Metamask QR addresses to a format our app can work with for sending, saving, and editing network preferences.

Conversion

1. ethereum: - prefix should be ignored and removed on our side

2. Status addresses follow the EIP-3770 format, which maps hexadecimal chain IDs to readable chain prefixes.

Name	EIP-155 (HEX)	DEC	EIP-3770
Mainnet	0x1	1	eth:
Binance Smart Chain	0x38	56	bsc:
Linea	0xe708	59144	linea:
Polygon	0x89	137	matic:
Arbitrum	0xa4b1	42161	arb1:
Optimism	0xa	10	oeth:

More networks: chains_mini.json file on chainid.network

After converting, ethereum:0x38cf6E0Ba4C4530735616e1Ee7ff5FbCB726fBd2@0xa should become oeth:0x38cf6E0Ba4C4530735616e1Ee7ff5FbCB726fBd2

This conversion should happen in all instances of scanning addresses, such as

• universal scanner on home pages
• scanner for saving addresses in wallet settings
• scanner for sending

It should be implemented on all supported platforms.

If the address contains an unsupported network, the user should receive an error "Address contains unsupported network" Users should not be able to save addresses with unsupported network prefixes to avoid problems in the send flow and sending assets to wrong networks.

Implementation.

1. Design cases for all relevant instances of QR scanner in Figma
2. Implement the conversion and validation logic
3. Submit the feature for review and approval by the Status QA team

Acceptance Criteria

• User scans Metamask QR addresses with relevant scanner instances
• Chain IDs are converted to prefixes according to EIP-3770
• ethereum: prefix is ignored and removed from address
• User receives a designated error for unsupported networks
• User can save addresses with supported and unsupported network prefixes

Future Steps Consider supporting Metamask's "Payment request" QR format including additional data like requested amount and token ID.

After discussing this issue with John it needs to be updated. Hold on...

cc @J-Son89 should it be included in 2.30?

[J-Son89]

It does seem like something worth having, let's put it lower priority than the high priority bugs, but once we get through them we can look at it? wdyt? 🤔

[churik]

Yes, I think it is required feature to be honest, agreed
