Instant sign in for smart accounts with ERC-6492

We just added support for ERC-6492 signatures in the TypeScript and DotNet SDKs. This means that you can now sign and verify signatures for smart accounts even if they haven't been deployed yet!

If your app uses smart accounts and sign in with ethereum (SIWE), this massively improves the first time user flow. Users can simply proceed to the app: there's no wait for the account to be deployed.

It also reduces cost for app developers, since the cost of deploying smart accounts is incurred on the first transaction, rather than when signing in.

No code changes for this one, just make sure you use the latest version of the SDK on both the signing and the verifying side, or any 6492 compatible signature verification library.

Happy building! 🛠️
