Staking
Stake Key Registration
Register stake credentials on the Cardano blockchain
Stake Key Registration
Before you can delegate or earn rewards, your stake credential must be registered on-chain. Registration requires a deposit (currently 2 ADA on mainnet) which is refunded when you deregister.
Basic Registration
import { , } from "@evolution-sdk/evolution"
const = ({
: "preprod",
: { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
: { : "seed", : ..!, : 0 }
})
declare const : .
const = await
.()
.({ })
.()
const = await .()
await .()The deposit amount is fetched automatically from protocol parameters.
Register and Delegate Together
The Conway era introduced combined certificates that register and delegate in one step, saving a certificate fee:
import { , } from "@evolution-sdk/evolution"
const = ({
: "preprod",
: { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
: { : "seed", : ..!, : 0 }
})
declare const : .
declare const : any
declare const : any
// Register + delegate to pool in one certificate
const = await
.()
.({
,
})
.()
const = await .()
await .()You can also combine registration with DRep delegation or both:
import { , } from "@evolution-sdk/evolution"
const = ({
: "preprod",
: { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
: { : "seed", : ..!, : 0 }
})
declare const : .
declare const : any
declare const : any
// Register + delegate to both pool and DRep
const = await
.()
.({
,
,
})
.()
const = await .()
await .()Script-Controlled Registration
For stake credentials controlled by Plutus scripts, provide a redeemer:
import { , , } from "@evolution-sdk/evolution"
const = ({
: "preprod",
: { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
: { : "seed", : ..!, : 0 }
})
declare const : .
declare const : any
const = await
.()
.({
: ,
: .(0n, []),
: "register-script-stake"
})
.({ : })
.()
const = await .()
await .()Next Steps
- Delegation — Delegate your registered stake
- Withdrawal — Claim accumulated rewards
- Deregistration — Remove credential and reclaim deposit
