ERC1155 NFTs/assets are not listed in the Safe

[johannesmoormann]

Part 1: Define the problem

What problem are you trying to solve?

NFTs that are using the 1155 standard are not visible under Collectibles and therefore can only be interacted with on a contract level. We are currently aware of at least 4800 NFTs following this standard being stored inside Safes.

What is your hypothesis?

If we enable 1155 support for collectibles, then these users will be able to see & interact with their ERC1155 assets as they are with all other supported assets and are more likely to use the Safe as a default account for NFTs in general.

What value does this bring to our customer and/or our mission? What is the goal?

Solving this problem would be part of a minimal support strategy for NFTs, while we have not aligned on a tangible NFT strategy overall yet. Next to drastically improving the UX for the users already holding these assets with the Safe, the perception of the Safe as a viable option for safekeeping NFTs in general is increased by supporting this standard.

How do we measure it?

no. of ERC1155 NFTs stored in Safes

Part 2: Shaping the problem

// Once the problem statement has passed the Great Filter, work with the team on the problem statement and elaborate on the following points to create more certainty around the problem and possible solutions. Make sure to identify dependencies and invite the necessary stakeholders early into the shaping process.

Non Goal(s)

The goal is not to provide an optimal experience for these NFTs but to allow the user basic interactions for the user with his assets.

Solution

Solution 1

Overview

Display Safe Apps inside /collectibles that are suitable for viewing and interacting with NFTs.

Existing Safe Apps that fulfill these requirements:

Zerion

• view ERC721+ERC1155 NFTs
• transfer ERC721+ERC1155 NFTs

plasma.finance

• view ERC721+ERC1155 NFTs
• transfer ERC721+ERC1155 NFTs

Add a tooltip explaining which NFTs are supported inside the web application.

Rough Scoping & Timeline

TBD with Web Team

Risk(s), Key Trade Offs & Decisions

• added friction by requiring the user to use an interface inside our interface to view and interact with their assets.
• no control over the UX
• leaving the UX for these assets to a third party that optimizes for NFT experience (e.g. Zerion will additional price info, filtering etc.)
• promotes the use of Safe Apps
• curation of the provided Apps required with a potential loss in neutrality if we e.g. only recommend Apps here which we see best fit
• no backend implementation required and lower effort frontend integration

Overview

Integration of ERC-1155 standard into our backend infrastructure e.g. primarily enable indexing to then be able to display them in the interface.

Open Questions

[johannesmoormann]

Lukas: Check out whether it is not more desirable to use other Safe apps to browse NFTs.

[DmitryBespalov]

If we just display ERC155 assets, would it be enough? Is sending/transfering such assets, and showing them in transaction details and transaction list also in scope?

:wave: my team and I manage a bunch of ERC-1155 tokens, but they don't show up in the safe. I know we can use Zerion, but would definitely prefer native support by Safe (like for ERC-721). Also AFAIK Zerion works only in mainnet, not other networks.

Why it's important for Safe UI to support the ERC-1155 standard?

• The Safe contract supports ERC1155Receiver (and that's great!) already. This means users can transfer tokens to their Safe but, unfortunately, the UI doesn't show them. This can be a source of confusion. I did a quick search on the Safe community discord and noticed that some users were confused.
• The standard offers many improvements over ERC-721, smaller gas footprints and—very very important—bulk operations for transfer, mint, and burn operations. Exposing them in the UI would allow users to save gas for these operations.
• Zerion only works for mainnet tokens.
• Zerion doesn't work on Safe mobile.
• I checked Dune analytics I see there are 13,835 ERC-1155 tokens stored in Safes. I guess a better metric would be to know how many different Safes have at least 1 ERC-1155 token, I don't have time to do the query on Dune now.
• Update: I tried to make Zerion work but I still have to figure out how to prepare a transaction. My guess is that I have to use the gnosis mobile app and scan the WalletConnect QRCode on Zerion, but I'm not sure (I talked to some people in discord and it seems it should work out of the box, didn't have this experience unfortunately, will investigate more).
