Struct safe_zk_token_sdk::instruction::withdraw::WithdrawData

source · 
#[repr(C)]
pub struct WithdrawData {
    pub pubkey: ElGamalPubkey,
    pub final_ciphertext: ElGamalCiphertext,
    pub proof: WithdrawProof,
}
Expand description

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
