Rewards Withdrawal

Staking rewards accumulate each epoch and must be explicitly withdrawn to your wallet. The withdraw operation claims rewards from a registered stake credential.

Basic Withdrawal

import { ,  } from "@evolution-sdk/evolution"

const  = ({
  : "preprod",
  : { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
  : { : "seed", : ..!, : 0 }
})

declare const : .

// Query current rewards via wallet
const  = await .()
.("Available rewards:", ., "lovelace")

// Withdraw all rewards
const  = await 
  .()
  .({
    ,
    : .
  })
  .()

const  = await .()
await .()

Zero-Amount Withdrawal (Validator Trigger)

Use amount: 0n to trigger a stake validator without actually withdrawing rewards. This is the coordinator pattern used by some DeFi protocols:

import { , ,  } from "@evolution-sdk/evolution"

const  = ({
  : "preprod",
  : { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
  : { : "seed", : ..!, : 0 }
})

declare const : .
declare const : any

// Trigger the stake validator with zero withdrawal
const  = await 
  .()
  .({
    : ,
    : 0n, // Don't actually withdraw — just trigger the validator
    : .(0n, []),
    : "coordinator-trigger"
  })
  .({ :  })
  .()

const  = await .()
await .()

This pattern is useful for validators that need to run stake-level checks as part of a larger transaction.

Script-Controlled Withdrawal

import { , ,  } from "@evolution-sdk/evolution"

const  = ({
  : "preprod",
  : { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
  : { : "seed", : ..!, : 0 }
})

declare const : .
declare const : any
declare const : bigint

const  = await 
  .()
  .({
    : ,
    : ,
    : .(0n, [])
  })
  .({ :  })
  .()

const  = await .()
await .()
