[bitbeckers]

Checklist

• Minter FE
• SDK
• Demo apps
• Safe minter app
• Marketplace SDK
• Indexer

Describe the feature you'd like to request

SDK uses Viem 1x, Marketplace SDK uses ethers V5, FE uses Wagmi + Rainbowkit, Demo apps use Wagmi + ConnectKit, VoiceDeck Safe minter uses Viem v1, Ethers 5, Ethers 6, etc..

We should align on connection lib, wallet lib and bring all stacks to the same version

Describe the solution you'd like

Viem > 2, Wagmi > 2, Rainbowkit > 2, with ethers V5 and ethers V6 adapters provided in the SDK.

Describe alternatives you've considered

Banging head against the wall.
