I have a Safe at https://etherscan.io/address/0x000000000034065b3a94c2118cfe5b4c0067b615#readProxyContract, and I was having trouble connecting it to both the Safe Web and Safe Mobile apps. When entering the address, I see this error: Address given is not a valid Safe address: Address given is not a valid Safe address

I didn't use the Safe UI to deploy, but it is still deployed from the canonical v1.4.1 factory on mainnet https://github.com/safe-global/safe-deployments/tree/main/src/assets/v1.4.1, which uses these addresses:

  • factory: 0x4e1DCf7AD4e460CfD30791CCC4F9c8a4f820ec67
  • singleton: 0x41675C099F32341bf84BFc5382aF534df5C7461a
  • fallback: 0xfd0732Dc9E303f09fCEf3a7388Ad10A83459Ec99

It seems the transaction did not have a "proxy" field set though, my transaction has this: manual

while a typical UI created safe has this: ui This might be specific to v1.4.1, as other createProxyWithNonce() transactions don't have this proxy field.


  • Do I need to verify this contract, and if so how should I do this?
  • If the above isn't the issue, what do I need to do to be able to connect this to Safe UI/Web/Mobile apps?

  1. Since the proxy address is indexed, it's now pushed to topics. If you look closely, the address is there in the topics.
  2. 1.4.1 is not supported on the UI/infra level yet; it will be supported in the UI once the support is implemented.
  • Thanks @mikheevm, is there any rough ETA on when we should expect UI/infra support?

  • Or are there details on what exactly needs to be updated on the UI/infra layer? Open to helping with the change myself if it's open source.

  • This is better asked in the web team discord or repos since it's out of the scope of the dev support.
