Deep-links interface should be equivalent to RPC interface

[danfinlay]

Maintaining our deep link interface is currently a per-method interface.

To simplify maintenance and increase its stability and security, we could build a query-param schema that is equivalent to our JSON-RPC interface, and pass those messages directly to our normal dapp provider infrastructure.

This would allow us to avoid any bugs that could arise from introducing new types of interfaces, like #1871

What is the state of this feature? Is there any way at the moment to call arbitrary function through Metamask Mobile?

[matteosistisette]

Is there a generic URL format to initiate an arbitrary transaction to an arbitrary contact with arbitrary data?? (as opposed to known methods of contracts that implement known interfaces)

[Fbartoli]

Any news on the release of that feature ?

I tried to call approve on polygon but not working.

Does someone knows a solution?

+1, tried to generate EIP-681 links for approve and even for transfer, seems that it doesn't work

[aerynquarmby]

any update on doing approvals with QR Code? e.g. https://metamask.app.link/send/pay-contractAddress/approve?address=receiverAddress&uint256=1e2
