Flux Point Studios Cardano Agent Skills Cardano CLI Staking

cardano-cli-staking

This is a guidance skill. Provides templates and explanations. For execution, use cardano-cli-staking-operator.

When to use

• Learning stake key registration and delegation
• Understanding rewards withdrawal
• Getting command templates for staking operations

Operating rules (must follow)

• Confirm network before providing commands
• Never execute—only provide templates
• Include deposit/fee information
• Verify pool ID from multiple sources

Docker fallback mode

If cardano-cli is not installed locally, use the wrapper script in this skill folder to run cardano-cli inside Docker (the Cardano node container images include the CLI).

chmod +x {baseDir}/scripts/cardano-cli.sh
{baseDir}/scripts/cardano-cli.sh version

Notes:

• The wrapper mounts your current directory into the container as /work so files like pparams.json, tx.body, datum.json work normally.
• If you have a local node socket, set CARDANO_NODE_SOCKET_PATH before running so query commands work.
• Override the image with CARDANO_DOCKER_IMAGE=ghcr.io/intersectmbo/cardano-node:<tag>.

Key concepts

Stake addresses vs payment addresses

• Payment address: Holds funds, used for spending
• Stake address: Controls delegation, receives rewards
• Base address: Combines both (most common)

Deposits

• Stake key registration: ~2 ADA deposit (refundable)
• Pool registration: ~500 ADA deposit (refundable)

Workflow templates

Check stake status

# Derive stake address
cardano-cli conway stake-address build \
  --stake-verification-key-file stake.vkey \
  --testnet-magic 1 \
  --out-file stake.addr

# Query status
cardano-cli conway query stake-address-info \
  --testnet-magic 1 \
  --address $(cat stake.addr)

Register stake key

# 1. Create registration certificate
cardano-cli conway stake-address registration-certificate \
  --stake-verification-key-file stake.vkey \
  --out-file stake-reg.cert

# 2. Build transaction with certificate
cardano-cli conway transaction build \
  --testnet-magic 1 \
  --tx-in <utxo>#<index> \
  --change-address <payment-addr> \
  --certificate-file stake-reg.cert \
  --out-file tx.unsigned

# 3. Sign with BOTH keys
cardano-cli conway transaction sign \
  --tx-file tx.unsigned \
  --signing-key-file payment.skey \
  --signing-key-file stake.skey \
  --testnet-magic 1 \
  --out-file tx.signed

# 4. Submit
cardano-cli conway transaction submit \
  --testnet-magic 1 \
  --tx-file tx.signed

Delegate to pool

# 1. Create delegation certificate
cardano-cli conway stake-address stake-delegation-certificate \
  --stake-verification-key-file stake.vkey \
  --stake-pool-id pool1... \
  --out-file delegation.cert

# 2. Build, sign (both keys), submit
# Same pattern as registration

Withdraw rewards

# 1. Check rewards balance
cardano-cli conway query stake-address-info \
  --testnet-magic 1 \
  --address $(cat stake.addr)

# 2. Build withdrawal tx
cardano-cli conway transaction build \
  --testnet-magic 1 \
  --tx-in <utxo>#<index> \
  --withdrawal $(cat stake.addr)+<reward-lovelace> \
  --change-address <payment-addr> \
  --out-file tx.unsigned

# 3. Sign with BOTH keys, submit

De-register stake key (get deposit back)

cardano-cli conway stake-address deregistration-certificate \
  --stake-verification-key-file stake.vkey \
  --out-file stake-dereg.cert

# Build tx with certificate, sign, submit

Examples

Example: Delegate to a pool

User request: "Delegate my stake to pool1abc..."

Response:

# === Delegate to Pool ===

POOL_ID="pool1abc..."
STAKE_VKEY="stake.vkey"
PAYMENT_ADDR=$(cat base.addr)

# 1. Verify pool exists
cardano-cli conway query stake-pools --testnet-magic 1 | grep $POOL_ID

# 2. Create delegation certificate
cardano-cli conway stake-address stake-delegation-certificate \
  --stake-verification-key-file $STAKE_VKEY \
  --stake-pool-id $POOL_ID \
  --out-file delegation.cert

# 3. Build transaction
cardano-cli conway transaction build \
  --testnet-magic 1 \
  --tx-in <your-utxo>#0 \
  --change-address $PAYMENT_ADDR \
  --certificate-file delegation.cert \
  --out-file tx.unsigned

# 4. Sign with both keys
cardano-cli conway transaction sign \
  --tx-file tx.unsigned \
  --signing-key-file payment.skey \
  --signing-key-file stake.skey \
  --testnet-magic 1 \
  --out-file tx.signed

# 5. Submit (use operator skill)
# Delegation takes effect at next epoch boundary

Safety / key handling

• Verify pool ID from multiple sources (adapools, cexplorer)
• Staking never risks your principal
• Delegation can be changed anytime
• Rewards accumulate until withdrawn
