Commands

Merry provides a variety of commands to manage your testing environment:

Starting Merry​

merry go

Starts all services, including the Bitcoin regtest node, Ethereum localnet node, explorers for the nodes and the catalog services.

  • --bare flag: Starts only the multi-chain services (Bitcoin and Ethereum nodes with explorers) and excludes catalog services. This option is useful if you don't need the additional functionalities such as Filler and Orderbook by Catalog.

  • --headless flag: Starts all services except for frontend interfaces. This can be helpful for running Merry in headless environments (e.g., servers) where a graphical user interface is not required.

Stopping Merry​

merry stop

# reset data
merry stop -d

Stops all running services. Use --delete or -d to remove data.

Getting logs​

merry logs -s <service>

# getting logs of evm service
merry logs -s evm

Replace <service> with the specific service (e.g., Filler, EVM) to view its logs.

Replacing a service with a local one​

merry replace <service>

This command allows you to replace a service with your local development version. Make sure you're in the directory containing the local service's Dockerfile. Supported services include Filler, Orderbook, and EVM.

Calling bitcoin rpc methods​

merry rpc <method> <params>

# example: get blockchain info
merry rpc getblockchaininfo

Interact with the Bitcoin regtest node directly using RPC methods.

Updating Docker images​

merry update

Keep your testing environment up-to-date by updating all Docker images.

Fund accounts​
