Get Validator Fee Token

fee.getValidatorToken

Gets a validator's preferred fee token.

Returns null when the fee manager contract reports the zero address. Validators with no preference set resolve to pathUSD at the node level.

Usage

import {  } from './viem.config'
 
const  = await ..({
  : '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
})
 
.('Fee token:', )
Fee token: { address: '0x20c0000000000000000000000000000000000001', id: 1n }

import { ,  } from 'viem/tempo'
 
export const  = .({
  : .('0x...'),
})

Recipes

Resolve the Effective Fee Token

Treat null as pathUSD when you need the token a validator actually gets paid in: unset preferences resolve to pathUSD at the node level.

import {  } from './viem.config'
 
const  = '0x20c0000000000000000000000000000000000000'
 
const  = await ..({
  : '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
})
const  =  ?? 
 
.('Validator is paid in:', )
Validator is paid in: 0x20c0000000000000000000000000000000000000

import { ,  } from 'viem/tempo'
 
export const  = .({
  : .('0x...'),
})

Survey Preferences Across a Validator Set

Read several validators in parallel to decide which stablecoins to stock before providing Fee AMM liquidity.

import {  } from './viem.config'
 
const  = [
  '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
  '0x8ba1f109551bD432803012645Ac136ddd64DBA72',
] as 
 
const  = await .(
  .(() =>
    ..({  }),
  ),
)
 
.()

import { ,  } from 'viem/tempo'
 
export const  = .({
  : .('0x...'),
})

  /** Fee token contract address. */
