Para provides the embedded wallet used inside Zedkr Cash.
Para uses a 2-of-2 multiparty computation signing model to authorize wallet transactions without assembling a complete private key in one place.
Neither Zedkr nor Para can independently sign a transaction from your wallet. You must still protect the email account and authentication methods connected to your Para wallet.

What is multiparty computation?
Multiparty computation, or MPC, is a cryptographic method that allows separate signing contributions to work together to authorize a transaction.
With Para’s 2-of-2 MPC model:
This reduces the risk associated with storing one complete private key in a single location.
With Para’s 2-of-2 MPC model:
- Two required signing contributions participate in the authorization.
- A complete private key is not assembled in one place during signing.
- Para cannot independently sign a transaction.
- Zedkr does not receive or control your private signing information.
- Zedkr cannot move funds from your wallet on your behalf.
This reduces the risk associated with storing one complete private key in a single location.
What does 2-of-2 mean?
A 2-of-2 signing model requires both signing contributions to authorize a transaction.
One party cannot independently complete the signature.
For your Zedkr Cash wallet, this means:
You remain responsible for reviewing and approving the transaction presented through your wallet.
One party cannot independently complete the signature.
For your Zedkr Cash wallet, this means:
- Para cannot independently authorize a transaction.
- Zedkr cannot independently authorize a transaction.
- Zedkr Support cannot move assets from your wallet.
- A cash-out cannot begin without your approval.
You remain responsible for reviewing and approving the transaction presented through your wallet.
Does Zedkr have my private key?

- Sign a transaction from your wallet

- Approve a cash-out
- Withdraw funds from your wallet
- Recover or provide your private credentials
