What it solves

Resolves #4391

How this PR fixes it

Adds two fields to off-chain msgs:

  • message hash
  • domain hash

Also makes those hashes always upper case to be easier to compare with what e.g. ledger displays

How to test it

  • Sign any off -chain msg and observe the new hashes

📦 Next.js Bundle Analysis for safe-wallet-web

This analysis was generated by the Next.js Bundle Analysis action. 🤖

⚠️ Global Bundle Size Increased

Page Size (compressed)
global 1009.82 KB (🟡 +90 B)
Details

The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

If you want further insight into what is behind the changes, give @next/bundle-analyzer a try!

Three Pages Changed Size

The following pages changed size from the code in this PR compared to its base branch:

Page Size (compressed) First Load
/apps/open 55.18 KB (🟡 +5 B) 1.04 MB
/transactions/messages 39.21 KB (🟡 +6 B) 1.02 MB
/transactions/msg 29.54 KB (🟡 +6 B) 1.01 MB
Details

Only the gzipped size is provided here based on an expert tip.

First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 20% or more, there will be a red status indicator applied, indicating that special attention should be given to this.

Nit: I'd add a comment why this is in uppercase for future reference.

capitalize?: boolean

const hash = capitalize ? `0x${hashValue.slice(2).toUpperCase()}` : hashValue

I'll leave it up to you, but we could create a helper to capitalise hex considering this is the third occurance.

  1. When I use our test app to create a message, I am getting completely different Message hash on the tx details and on the Ledger ( connection via MM)
    Message details : 0xFE941E7B8C41664AE6E4A4BBEA7183DF9305DAC5258429AC157386E9B6B94B99

There are many things called message hash / safe message hash here sadly.

Are you sure you were comparing the message hash with what ledger displays? For me they match.

@liliya-soroka please get back to us on this one. This PR only adds new fields so unlikely to break anything else.

The both issues are still existing for me
Yes, I am sure that I am checking the right fields , not signmessage and signmessagehash

As you can see the messagehash on message details and on the ledger are different, the domainhash was correct
