Approve an amount of asset for transfer by a delegated third-party account.

Origin must be Signed.

Ensures that ApprovalDeposit worth of Currency is reserved from signing account for the purpose of holding the approval. If some non-zero amount of assets is already approved from signing account to delegate, then it is topped up or unreserved to meet the right value.

NOTE: The signing account does not need to own amount of assets at the point of making this call.

  • id: The identifier of the asset.
  • delegate: The account to delegate permission to transfer asset.
  • amount: The amount of asset that may be transferred by delegate. If there is already an approval in place, then this acts additively.

Emits ApprovedTransfer on success.
