Struct safe_token_2022::extension::confidential_transfer::instruction::WithdrawData

pub struct WithdrawData {
    pub pubkey: ElGamalPubkey,
    pub final_ciphertext: ElGamalCiphertext,
    pub proof: WithdrawProof,
}

This struct includes the cryptographic proof and the account data information needed to verify the proof

• The pre-instruction should call WithdrawData::verify_proof(&self)
• The actual program should check that current_ct is consistent with what is currently stored in the confidential token account TODO: update this statement

Fields

pubkey: ElGamalPubkey

The source account ElGamal pubkey

final_ciphertext: ElGamalCiphertext

The source account available balance after the withdraw (encrypted by source_pk

proof: WithdrawProof

Range proof
