+# Sponsoring
+
+![Sponsoring flow](./sponsoring-flow.drawio.svg)
+
+## Implementation
+
+If you need to add sponsoring for pallet call, you should implement `SponsorshipHandler<AccountId, Call, ()>`, see `UniqueSponsorshipHandler` for example.
+
+If you need to add sponsoring for EVM contract call, you should implement `SponsorshipHandler<CrossAccountId, (H160, Vec<u8>), CallContext>`, see `UniqueEthSponsorshipHandler` for example.
+
+## EVM bridging
+
+In case if Ethereum call is being called using substrate `evm.call` extrinsic, `BridgeSponsorshipHandler` is used to convert between two different `SponsorshipHandler` types
