Sponsor Fee Transaction

Sponsor Fee transaction enables or disables sponsorship. Sponsorship allows any user to pay a fee in the sponsored asset (instead of WAVES) for Invoke Script transactions and Transfer transactions. More about sponsorship

Only the asset issuer can set up sponsorship.

Smart asset cannot be a sponsored asset.

Transaction Fee

The minimum fee for the Sponsor Fee transaction is 0.001 WAVES. (Before activation of feature #15 “Ride V4, VRF, Protobuf, Failed transactions” it was 1 WAVES.)

If the transaction sender is a dApp or smart account, and the complexity of the account script or dApp script verifier function exceeds the sender complexity threshold, the minimum fee is increased by 0.004 WAVES. (Before activation of feature #16 “Ride V5, dApp-to-dApp invocations”, the extra fee of 0.004 WAVES was required regardless of the complexity of the account script or the presence and complexity of the dApp script verifier function.)
