The fees sub-client manages fee operations for tokenized vaults, including crystallization, claiming, and protocol fee configuration. For an overview of the fee structure, see Fees.

​
Fee Lifecycle

Fees in GLAM tokenized vaults follow a three-step lifecycle:
  1. Accrue — Fees accumulate based on the vault’s fee structure (management, performance, subscription, redemption)
  2. Crystallize — Accrued fees are calculated and recorded onchain
  3. Claim — Crystallized fees are transferred to the manager and protocol

​
Crystallize Fees

Crystallize accrued management and performance fees. This must be called before claiming: 
import { GlamClient } from "@glamsystems/glam-sdk";

const glamClient = new GlamClient();

const txSig = await glamClient.fees.crystallizeFees();
Crystallization triggers vault pricing internally. The vault must have up-to-date price data for accurate fee calculation.

​
Claim Fees

Claim crystallized fees. Fees are distributed to the vault manager and the protocol: 
const txSig = await glamClient.fees.claimFees();

​
Query Fees

​
Get Claimable Fees

View fees that have been crystallized and are ready to claim: 
const claimable = await glamClient.fees.getClaimableFees();

​
Get Claimed Fees

View the history of fees that have already been claimed: 
const claimed = await glamClient.fees.getClaimedFees();

​
Set Protocol Fees

Configure protocol-level fee rates (requires protocol authority): 
await glamClient.fees.setProtocolFees(
  1,    // baseFeeBps (basis points)
  2000, // flowFeeBps (basis points)
);
