CLI

There is 9 extra steps involved when dealing with Confidential Transfers using Solana Token Extensions
  1. Create token
spl-token --program-2022 create-token --enable-confidential-transfers auto --decimals 0
  1. Create sender account
spl-token create-account <mint_pubkey>
Note:- The destination account will need to create their own account to be able receive
  1. Enable Confidential Transfers for the account
spl-token configure-confidential-transfer-account <mint_pubkey>
  1. Mint tokens
spl-token mint <mint_pubkey> 1
  1. Deposit
spl-token deposit-confidential-tokens <mint_pubkey> 1
  1. Apply on sender account
spl-token apply-pending-balance <mint_pubkey>
  1. Transfer to destination
spl-token transfer <mint_pubkey> 1 <dest_pubkey> --confidential
  1. Apply to destination account
spl-token apply-pending-balance --address <destination_pubkey>
  1. Withdraw at destination
spl-token withdraw-confidential-tokens <mint_pubkey> 1 --address <dest_pubkey>
