When signing from a multisig address, the process is

1. building the transaction using `setSender(multisigAddr)`
2. assembling signatures of the participants of the multisig and possibly the gas-owner/sponsor if any.
3. executing the transaction passing the transaction bytes and above signatures with `SuiClient.executeTransactionBlock`.

Do you have a code snippet we can maybe debug?

1. I assume the `address` you use is the multisig address, correct?
2. If `signTransaction()` uses a wallet to sign, I suppose it signs it with a simple address, not a multisig. If so, you need to do use `MultisigPublicKey.combinePartialSignatures()` as [here](https://sdk.mystenlabs.com/typescript/cryptography/multisig#combining-signatures-with-a-multisigpublickey)
