Smart Wallet Signing Enhancements in Unreal Engine
Authenticate as a Smart Wallet in all the right ways.
We've integrated EIP-1271 and EIP-6492 Smart Wallet signing into the UE SDK so you can verify auth seamlessly from your backend without having to deploy your smart wallets.
No changes to your code are required, simply upgrade to the latest SDK, and your signatures will now match what most authentication systems expect from smart wallets.
This is now at parity with our other SDKs (TS, React, .NET, Unity, etc.)
