Delegating your stake

how to create the delegation certificate

Stake is concentrated in accounts, and you will need your account key to delegate its associated stake.

You will need your:

  • account public key: a bech32 string of a public key
  • the Stake Pool ID: an hexadecimal string identifying the stake pool you want to delegate your stake to.
$ jcli certificate new stake-delegation STAKE_POOL_ID ACCOUNT_PUBLIC_KEY > stake_delegation.cert

how to sign your delegation certificate

We need to make sure that the owner of the account is authorizing this delegation to happens, and for that we need a cryptographic signature.

We will need the account secret key to create a signature

$ cat stake_delegation.cert | jcli certificate sign account_key.prv | tee stake_delegation.cert

The output can now be added in the transaction and submitted to a node.

submitting to a node

The jcli transaction add-certificate command should be used to add a certificate before finalizing the transaction.

For example:

...

jcli transaction add-certificate $(cat stake_delegation.cert) --staging tx

jcli transaction finalize CHANGE_ADDRESS --fee-constant 5 --fee-coefficient 2 --fee-certificate 2 --staging tx

...

The --fee-certificate flag indicates the cost of adding a certificate, used for computing the fees, it can be omitted if it is zero.

See here for more documentation on transaction creation.
