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 after the activation of feature #15 “Ride V4, VRF, Protobuf, Failed transactions”.
• 1 WAVES before activation of feature #15.

If the transaction sender is a dApp or smart account, the minimum fee is increased by 0.004 WAVES.

Starting from node version 1.3.1, after activation of feature #16 “Ride V5, dApp-to-dApp invocations”, the extra fee of 0.004 WAVES is only required if the complexity of sender's account script or dApp script verifier function exceeds the sender complexity threshold. Versions 1.3.x are currently available for Stagenet only.
