Gnosis Safe: Chiado v.1.3.0 - unsupported base contract

Question

I'd like to deploy the Safe Singleton contract v1.3.0 on Mainnet and Gnosis (Sepolia and Chiado on testing), but I see a warning in SafeWalletUI when using the Chiado network.

Deployment is done via SafeSDK:

const safeFactory = await SafeFactory.init({
  isL1SafeSingleton: true,
  provider: RPC_URL,
  safeVersion: '1.3.0',
  signer: env.SAFE_PROVIDER_PRIVATE_KEY,
})

const safeContract = await safeFactory.deploySafe({
  owners: ['owner1', 'owner2', 'owner3'],
  threshold: 1,
})

Sepolia Safe: https://app.safe.global/transactions/history?safe=sep:0x25cc7d4bCA86B75937f9F6D1D26db649bDB2FF41 -> everything is correct

Chiado Safe: https://app.safe.global/transactions/history?safe=chiado:0x98E0932f6A803068052BD2d43827F49840d7B1F5 -> warning

Double check of supported networks https://docs.safe.global/advanced/smart-account-supported-networks?version=v1.3.0&search=chiado&expand=10200, and the factory and master copy contract addresses are the same.

FYI: I deployed a L2 contract on Chiado a few weeks ago and it looks ok https://app.safe.global/settings/setup?safe=chiado:0xB104d8E65e1933c226d1350C6A9fe9BBE3e5f6e2

Do you know why SafeWalletUI doesn't support the singleton contract?

Answer 1

Thanks for the good question.

Chiado, the testnet of Gnosis, is an unfortunate special case for Safe, as the deployment of the Safe Singleton Factory failed (transaction). This has only happened once in the history of Safe.

The address of the Safe Proxy Factory in the image is different from the address on all other chains, leading to errors.

I have contacted the Wallet team about the error you encountered with the Wallet and will get back to you soon.

Unfortunately, the only answer regarding the SDK is that we don't currently support Chiado. I'm sorry about that, and I hope you find another testnet where you can experiment with Safe.
