Registering as a SanchoNet delegate representative (DRep)

Pre-requisites

• Payment address with funds
• A SanchoNet node

Generate SanchoNet DRep keys and an ID

1. Generate a DRep key pair:

cardano-cli conway governance drep key-gen \
--verification-key-file drep.vkey \
--signing-key-file drep.skey

{
    "type": "DRepSigningKey_ed25519",
    "description": "Delegate Representative Signing Key",
    "cborHex": "5820eba7053fdc9cb3b8aacf142d3d4ad575bb48fb92f4082d81605ac8e2ccfead5d"
}

{
    "type": "DRepVerificationKey_ed25519",
    "description": "Delegate Representative Verification Key",
    "cborHex": "5820c19e0e939609531cfd04dcfa5bf1a5f3e245aa88e163759341aba296af34cc7e"
}

2. Generate a SanchoNet DRep ID:

cardano-cli conway governance drep id \
--drep-verification-key-file drep.vkey \
--out-file drep.id

Generate the registration certificate

1. Create a SanchoNet DRep registration certificate

There are three ways to generate the certificate:

• Using the drep.vkey file:

cardano-cli conway governance drep registration-certificate \
--drep-verification-key-file drep.vkey \
--key-reg-deposit-amt $(cardano-cli conway query gov-state --testnet-magic 4 | jq -r .currentPParams.dRepDeposit) \
--out-file drep-register.cert

• Using the DRep verification key:

cardano-cli conway governance drep registration-certificate \
--drep-verification-key "$(cat drep.vkey | jq -r .cborHex | cut -c 5-)" \
--key-reg-deposit-amt $(cardano-cli conway query gov-state --testnet-magic 4 | jq -r .currentPParams.dRepDeposit) \
--out-file drep-register.cert

• Using the DRep ID:

cardano-cli conway governance drep registration-certificate \
--drep-key-hash $(cat drep.id) \
--key-reg-deposit-amt $(cardano-cli conway query gov-state --testnet-magic 4 | jq -r .currentPParams.dRepDeposit) \
--out-file drep-register.cert

Any of the above methods produces drep-register.cert, which contains:

{
    "type": "CertificateShelley",
    "description": "DRep Key Registration Certificate",
    "cborHex": "84108200581c555c5b537f552d885c1959c714282eb6ac06de5e2aee850c374d394e00f6"
}

Submit certificate in a transaction

1. Submit the SanchoNet DRep registration certificate in a transaction.

• Build:

cardano-cli conway transaction build \
--testnet-magic 4 \
--witness-override 2 \
--tx-in $(cardano-cli query utxo --address $(cat payment.addr) --testnet-magic 4 --out-file  /dev/stdout | jq -r 'keys[0]') \
--change-address $(cat payment.addr) \
--certificate-file drep-register.cert \
--out-file tx.raw

• Sign:

cardano-cli conway transaction sign \
--tx-body-file tx.raw \
--signing-key-file payment.skey \
--signing-key-file drep.skey \
--testnet-magic 4 \
--out-file tx.signed

• Submit:

cardano-cli conway transaction submit \
--testnet-magic 4 \
--tx-file tx.signed
