Wipe a token

Wipes the provided amount of fungible or non-fungible tokens from the specified Hedera account. This transaction does not delete tokens from the treasury account. This transaction must be signed by the token's Wipe Key. Wiping an account's tokens burns the tokens and decreases the total supply.

• If the provided account is not found, the transaction will resolve to INVALID_ACCOUNT_ID.

• If the provided account has been deleted, the transaction will resolve to ACCOUNT_DELETED

• If the provided token is not found, the transaction will resolve to INVALID_TOKEN_ID.

• If the provided token has been deleted, the transaction will resolve to TOKEN_WAS_DELETED.

• If an Association between the provided token and the account is not found, the transaction will resolve to TOKEN_NOT_ASSOCIATED_TO_ACCOUNT.

• If Wipe Key is not present in the Token, the transaction results in TOKEN_HAS_NO_WIPE_KEY.

• If the provided account is the token's Treasury Account, the transaction results in CANNOT_WIPE_TOKEN_TREASURY_ACCOUNT

• On success, tokens are removed from the account and the total supply of the token is decreased by the wiped amount.

• The amount provided is in the lowest denomination possible.

  • Example: Token A has 2 decimals. In order to wipe 100 tokens from an account, one must provide an amount of 10000. In order to wipe 100.55 tokens, one must provide an amount of 10055.

• This transaction accepts zero-unit token wipe operations for fungible tokens (HIP-564)
