protocol_fee package

Overview

Package protocol_fee manages fee collection and distribution for GnoSwap protocol operations.

This contract collects fees from various protocol operations (swaps, pool creation, withdrawals, staking claims) and distributes them to DevOps and Governance Stakers according to configurable percentages.

Distribution Targets:

  • DevOps: Development and operations fund (default 0%)
  • GovStaker: Governance stakers / xGNS holders (default 100%)

Key Functions:

  • DistributeProtocolFee: Distributes accumulated fees to recipients
  • SetDevOpsPct/SetGovStakerPct: Configure distribution percentages
  • AddToProtocolFee: Adds fees to the distribution queue

The contract uses a version manager pattern for upgradeable implementations.

Function

RegisterInitializer

func RegisterInitializer(cur realm, initializer func(_ int, rlm realm, protocolFeeStore IProtocolFeeStore) IProtocolFee)

RegisterInitializer registers a new pool implementation version. This function is called by each version (v1, v2, etc.) during initialization to register their implementation with the proxy system.

The initializer function creates a new instance of the implementation using the provided protocolFeeStore interface. It receives a realm value that resolves to the protocol_fee proxy realm — the only address with write permission on the shared KV store — so any per-version store bootstrapping performed inside the initializer passes the proxy's authorization check.

Security: Only contracts within the domain path can register initializers. Each package path can only register once to prevent duplicate registrations.
