getFeeRateOverride

Read a per-user fee rate override.

When present, the override replaces the volume-tiered fee schedule for the user on every fill. Overrides are set by the chain owner.

Signature

function getFeeRateOverride(
  client: Client,
  parameters: {
    user: Address
    height?: number
  },
): Promise<FeeRateOverride | null>

Example

import { createPublicClient, createTransport, testnet } from "@left-curve/sdk"
import type { Address } from "@left-curve/sdk"
 
const client = createPublicClient({ chain: testnet, transport: createTransport() })
const user: Address = "0x1234567890abcdef1234567890abcdef12345678"
 
const override = await client.getFeeRateOverride({ user })

Parameters

user — Address. The trader.

height — number, optional. Block height. Default 0 (latest).

Returns

FeeRateOverride | null — { makerFeeRate, takerFeeRate }, or null if no override is set. The contract returns a tuple [string, string]; the action reshapes it into the object form.
