Does Reown Unity/Android/iOS SDK AppKit support signing a transaction (without sending it)?

[anderstwin5]

Hi Reown team,

I'm currently researching the Reown SDK (Unity, Android, and iOS), and I would like to know whether there is any built-in support for signing a transaction without broadcasting it — in other words, I only need the signed raw transaction from the user’s wallet.

I’ve checked that SignTypedDataAsync is available in the Unity SDK, which is great for EIP-712 messages, but I couldn't find any method for signing actual Ethereum transactions (especially EIP-1559 typed transactions) without sending them.

As an alternative, I tried sending a raw eth_signTransaction RPC request directly, but the wallet responds with "unknown account". This suggests the SDK or connected wallet does not expose a signing method for transactions.

So I wanted to ask:

Is there any method like signTransaction or equivalent available in any of the SDKs?

If not, are there any plans to support this feature in the near future?

Thanks in advance!

Hello,

Currently, we don't support eth_signTransaction with wallets, but we could add it. What are you building and why not use eth_sendTransaction?

[anderstwin5]

The blockchain platform (game) that is being integrated needs to handle transaction processing on the game server rather than using a wallet, so the eth_signTransaction method is required instead of eth_sendTransaction.

We could add this feature for you, but I'd like to learn more about your use case and project. Let's set up a Telegram group? Drop me an email: gleb at reown.com
