Use this guide to deploy a local testnet instance of cdk-opgeth using Kurtosis. This includes a local L1 + L2 environment with Agglayer components and OP Stack infrastructure.

​
1. Install Kurtosis

Follow the installation instructions from the Kurtosis official docs.

​
2. Launch the cdk-opgeth Stack

Use the command below to run the Kurtosis package: 
kurtosis run \
  --enclave cdk \
  --args-file https://raw.githubusercontent.com/0xPolygon/kurtosis-cdk/refs/tags/v0.4.0/.github/tests/chains/op-succinct.yml \
  github.com/0xPolygon/kurtosis-cdk@v0.4.0
This will:
  • Start an L1 devnet (Ethereum-like chain)
  • Deploy Agglayer common contracts
  • Deploy op-geth, op-node, and op-batcher
  • Deploy Aggkit and op-succinct infrastructure
Kurtosis service output

​
3. Bridge Funds from L1 to L2

Use polycli to bridge assets from L1 to L2: 
polycli ulxly bridge asset \
  --bridge-address $(kurtosis service exec cdk contracts-001 'jq -r '.polygonZkEVMBridgeAddress' /opt/zkevm/combined.json') \
  --private-key 0x12d7de8621a77640c9241b2595ba78ce443d05e94090365ab3bb5e19df82c625 \
  --destination-address 0x9175f8176014543492234099F37a385335a017d6 \
  --destination-network 1 \
  --value 1000000000000000000 \
  --rpc-url http://$(kurtosis port print cdk el-1-geth-lighthouse rpc)
Kurtosis service output
Command parameters:
  • polycli ulxly bridge asset: Initiates the bridge
  • --bridge-address: Reads from combined.json
  • --private-key: Specifies the sender wallet
  • --destination-address: L2 recipient
  • --destination-network: Target network ID (1 for devnet)
  • --value: Amount to bridge in wei
  • --rpc-url: Dynamically resolved RPC from Kurtosis
A successful call returns a transaction confirmation. Kurtosis service output

​
4. Check Balance on L2

cast balance --ether \
  --rpc-url $(kurtosis port print cdk op-el-1-op-geth-op-node-001 rpc) \
  0x9175f8176014543492234099F37a385335a017d6
Kurtosis service output

​
5. Send a Transaction on L2 (Inscription)

cast send \
  --rpc-url $(kurtosis port print cdk op-el-1-op-geth-op-node-001 rpc) \
  --private-key 0xfa5f1cc57271a4ccbc5f0becd6bbca6a542973fa2b323d918c5e625fb67bdb20 \
  0x9175f8176014543492234099F37a385335a017d6 \
  $(echo -n 'data:,Hello Agglayer!' | xxd -p)
This command sends a transaction with Hello Agglayer! embedded in the calldata. Kurtosis service output

​
6. View the Inscription

cast tx \
  --rpc-url $(kurtosis port print cdk op-el-1-op-geth-op-node-001 rpc) \
  0x2ec6e2097ef85360cdb1fde9d711412c4ce304a79da5afa69ef9abdbebd6757e input | \
  xxd -r -p
Expected output: 
data:,Hello Agglayer!
