Is it possible to create a safe multisig on base that has the same address as a safe multisig deployed on eth mainnet?

During a token presale we had a few customers accidentally send their funds to a our safe address on base instead of mainnet and we are trying to determine if the funds are recoverable at all or totally lost.

Any guidance is hugely appreciated!

    It may or may not be possible, depending on which contracts were used for eth multisig and if they're deployed to the same address on the base network

It might be possible, if the address is not already taken by someone else . Go to Base's SafeProxyFactory address and use getCounterfactual function to get the address you want. Every Safe Multisig address has been deployed with some nonce/salt . Enter the same salt and you might be able to get the same on base
