Ragequit Operation

This operation converts all the encrypted Tongo balance to ERC20 tokens and sends them to the given starknet account address. The parameters are:

• to: The starknet account address to send the ERC20 to.
• sender: The sender of the transaction.
• feeToSender (optional, v2): An amount of Tongos paid to the transaction sender, used to reimburse a relayer. See Relaying.

const ragequitOp = await tongoAccount.ragequit({
    to: "RECEIVER_STARKNET_ACCOUNT_ADDRESS",
    sender: "SENDER_ADDRESS"
});

const tx = await signer.execute([ragequit.toCalldata()]);
await provider.waitForTransaction(tx.transaction_hash);

Balance Handling

When receiving a Ragequit operation, the user discloses the total encrypted Tongo balance, after sending the unwrapped ERC20 to the starknet account address, the cairo contract resets the user's balance to zero. The pending balance of the account is not manipulated in this operation.

Zero-Knowledge Proof

In this operation, the ZK proof given by the sender shows:

• Ownership of the user account.
• The disclosed amount is the total balance of the user's account.
