Add moonbeam to type_registry #172

Closed johnuopini closed 2 years ago

johnuopini commented 2 years ago

I tested signing an extrinsic in moonbase alpha and its working just fine, the very same code fails on moonbeam with the error below. I have tried the transaction via JS and it works as expected. I guess it might be related on type_registry not being updated for moonbeam in the library.

Did you update package scalecodec to latest version (v1.0.27)? Latest version I added specific changes for Moonbeam, in next release of substrate-interface I make sure I'll bump this package requirement to latest version as well

Updated from 1.0.26 to 1.0.27 and it works perfectly, good stuff!!!
