Fee Claiming

It is possible to periodically withdraw rewards for the Vault's fee shareholders through the Fee Splitter system.

IconPrerequisites
  • Set Fee Claimer Role: In your Vault settings, assign the operator's wallet address as the Fee Claimer in the Roles tab
  • Start with Flag: Add the --claim-fee-splitter flag when starting the Operator Service

Configuration​

The automated fee claiming process can be configured using environment variables:

IconEnvironment Variables

FEE_SPLITTER_INTERVAL - Controls how often fee claiming runs in seconds (default: 86400 seconds = 24 hours)

FEE_SPLITTER_MIN_ASSETS - Minimum amount accumulated in the fee splitter contract (in Wei) before processing withdrawals to avoid unnecessary gas fees (default: 1000000000000000 Wei = 0.001 ETH)

How It Works​

The fee claiming task combines multiple operations into a single multicall transaction:

  1. Harvest vault rewards from Keeper contract
  2. Withdraw splitter rewards on behalf of each shareholder (rewards go to exit queue)
  3. Claim exited assets on behalf of each shareholder (assets go directly to shareholder addresses)

Usage​

# Start operator with fee claiming enabled
./operator start-local \
  --vault=0x3320a68 \
  --consensus-endpoints=http://localhost:5052 \
  --execution-endpoints=http://localhost:8545 \
  --claim-fee-splitter
IconGas Optimization

To avoid unnecessary gas fees from the operator's wallet, withdrawals are processed only if their total amount exceeds the minimum threshold set by FEE_SPLITTER_MIN_ASSETS.
