Rollover Operation

This operation takes the pending balance of the account and converts it to actual usable balance for the account. The parameter is:

• sender: The sender of the transaction.

const rolloverOp = await account.rollover({
    sender: "SENDER_ADDRESS"
});

await signer.execute([rolloverOp.toCalldata()]);

Balance Handling

When receiving a Rollover operation, the cairo contract adds the user's pending balance to the user's balance. After that the user's pending balance is reseted to zero.

Zero-Knowledge Proof

In this opretaion, the only thing that has to be proven is the ownership of the Tongo account. This is done by proving knowledge of the account's private key.
