ZKSAFE supports the transfer of NFT（ERC721）besides tokens (ERC20), other asset types (such as ERC1155) are not supported for now

Social Recovery

If you forget the password or private key, you can transfer ownership of the safebox to your other new wallet, so you can use the new wallet's on-chain password + private key to withdraw the assets

There are 2 ways for transferring the ownership of the safebox:

1. Set multi-signing wallet ahead, which can be your cold wallet or your friend’s wallet, to initiate multi-signing

2. Use your on-chain password and your private key

The original wallet will be invalid after your transferring the ownership of the safebox to new wallet

Reminding：ZK-SNARK is still need time for testing, and we could exclude the possibility of assets loss caused by password issues, so it’s strongly suggested that each user can set the multi-signing
