Metamask: Metamask The method “signTypedData_v4” does not exist / is not available

Error with Metamass and Signed Data Type 4. Version (V3)

Since my last update, Metamcus has been limited support for the signed version 4. The “Signattypedata_V4” method is really available in the latest protocol standards.

This means that when trying to use data with signed metamcular species, you will face a mistake that indicates that it does not exist. However, I will give some bypassing solutions and explanations how this limit affects you:

What do “Signtypeddata_V4” do?

Signattypeddata_v4 is the method used by Ethereum 2.0 to transfer data for the signed type between the Ethereum virtual machine (EVM) and the signatories to Metamacus.

Why “Signtypedadata_V4” is not available in the latest protocol standards?

Version 4. The latest Protocol standards of the signed data do not include the potpitypeddata_v4 method. These changes could be made to customize new features or improve performance.

bypasses and solutions

Since “PotPitypeddata_V4are no longer supported, you can use one of the following alternatives:

1
Use the Signed Data Type 3. Version (V2)

: You can still use the data with a signed type with Metamcus to determine the "sign" signature_V2 format. This will allow you to transfer data on the signed species between EVM and the signatory agreement.

`JavaScript

Const Typeddata = New Typedadata.Signypeddddda2 ({{{{{{{{{{{{{{{{{{{{

Type: ‘SignanPeddata_v2’,

Value: {{

// Signed type type here

ICE

});

`

• Use a library or module that supports signed type types : Libraries and modules are available that provide support for a signed type, such as “Metamk unrelated-mypedata”. These libraries could offer more features and flexibility than Metamcus supported support.

Conclusion

Shortly due to the “Signtypeddata_V4” limit limit, you cannot use it with the Metamcus signed data type version 4. You can still use data with a signed type of metamics by determining the “potpippedata_v2” format or using the library it supports it.
