The tipping pallet will enable sending the community contributions (tips) to verified creators currently in the Anagolay native tokens and later, using fiat and many Dotsama ecosystem tokens. To prevent the misuse of the pallet and to make sure that the correct people are supported, the tipping pallet depends on the verification pallet to get the proofs of the domain, username or repository verification, and statements pallet for the ownership.

Tipping pallet is the core feature in our attempt to build the functionality and features to support creators’ economy in a truly decentralized manner.

Every creator can verify their revenue channels like websites, subdomains, or a username on commercial websites and accept payment from anybody in crypto.

Sending a tip to a verified online identity:


The runtime needs to configure the tipping pallet as follows:

  impl tipping::Config for Runtime {
type Event = Event;
type Currency = Balances;
type TimeProvider = pallet_timestamp::Pallet<Runtime>;
type WeightInfo = tipping::weights::AnagolayWeight<Runtime>;

/// Limit on the maximum number of tips that will be recorded, per context.
/// This only affects the showing of the last X transactions when rpc is called

There is one constant available for configuration:

  • MAX_TIPS_PER_VERIFICATION_CONTEXT: specifies the amount of tips which will be recorded per verification context. Once reached this limit, the older tips are discarded. Does not affect receiving tips, and it is used to show last X of the transactions when the getTips RPC is called


  • TippingSettingsByAccountIdAndVerificationContext The map of TippingSettings indexed by their respective AccountId and VerificationContext
  • TipsByAccountIdAndVerificationContext Provides a collection of Tips indexed by their respective receiver AccountId and VerificationContext


  • TippingSettingsUpdated produced upon tipping settings update
  • TipCreated produced upon the newly created tip


  • InvalidVerificationContext happens when verification context is not associated to a successful verification request and cannot be tipped
  • InvalidConfiguration happens when trying to tip a verification context is not set-up to enable tipping


  • TippingSettings is a structure associated with VerificationContext, providing the tipping settings
    • context: the verification context this setting applies to
    • enabled: specifies that the tipping is enabled or not
    • account: specifies to which wallet to send the tips given in some kind of token
  • Tip structure representing a tip, providing the following fields:
    • amount - quantity of tokens tipped
    • sender - the AccountId that is tipping
    • sender - the AccountId that is receiving the tip
    • createdAt - timestamp of the tip, in seconds
    • blockNumber: block where the tip was inserted


  1. update_settings accepts a collection of TippingSettings and stores it. A coherency check is performed on the rightfulness of the caller to configure each setting. Infact, the single setting won't be stored if the caller is not the holder of the verification request for the respective context, or if such request has a status different from Success. In the end, a TippingSettingsUpdated event is raised
  2. tip accepts a Tip for a VerificationContext and stores them in the TipsByAccountIdAndVerificationContext while it transfers of the required amount from the account of the sender to the account of the receiver.
