otherProviderFlagsExist for metamask is unnecessary

[puderty]

Current Behavior

for metamask, you have a otherProviderFlagsExist check, and lot of wallet set isMetamask to true with their own flag. And then the user can't connect by metamask even if the wallet is metamask compatible. Why is this necessary?

Expected Behavior

Steps To Reproduce

connect to dapp demo in okx mobile wallet by click on metamask

And also why is platform restricted to desktop for okx wallet?

@puderty the OKX wallet integration was done by the OKX team. If you would like to open a PR to add mobile support and test please feel free to do so.
otherProvidersFlagsExists method is necessary to reduce spoofing. Wallets should not set both flags to be true, this is bad UX and misleading users. MetaMask is the only wallet that should set isMetaMask to true and MetaMask should be the only wallet that opens if the user selects MetaMask.
Im not sure what you mean by MetaMask compatible, can you please clarify?

[puderty]

For some dapp not using your sdk, and if they only integrate with metamask, if we don't set ismetamask to true, the dapp cannot connect to okx mobile wallet. So we have to set it for compatible reason, but your check will broken it and make it cannot connect by click on metamask when using blocknative.

I'm from okx wallet mobile team, if otherProvidersFlagsExists is necessary, can you change the platform from desktop to all for okx wallet?

[Adamj1232]

@puderty set it for compatible reason is spoofing and is a misleading UX.
If you are from the OKX team please pass this along to the dev team.
If the wallet is to be used the provider flag needs to be specified and not rely upon MetaMask to mislead people into selecting one wallet and getting another.
I opened a PR to update the devices for OKX: #1901

[puderty]

But can we remove otherProvidersFlagsExists on mobile? Because the on mobile app there should be only one injected ethereum object and it's injected by the mobile web3 wallet the user is using.

[Adamj1232]

@puderty that update was made as part of this PR - https://github.com/blocknative/web3-onboard/pull/1901/files and will be merged into staging shortly.
This should allow OKX wallet to display properly on mobile. We wont be removing otherProvidersFlagsExists from MetaMask as this is to avoid spoofing of wallets.

[puderty]

Can you add some flag under window object so we can check that the dapp is using this library? So we can avoid setting other flags for dapps using this library. Such as window.isUsingBlockNative = true.

[Adamj1232]

We don't alter the provider object on the window so there is not a flag we can set. Please try using the latest alpha packages of core, react or vue to see if the update to the device settings for OKX wallet solves the issue - See #1901 for those versions
