The Rundler Command Line Interface (CLI) offers a wide array of options and subcommands. Most options contain reasonable defaults that can be overridden.
node
: Runs the Pool, Builder, and RPC servers in a single process.rpc
: Runs the Rpc server.pool
: Runs the Pool server.builder
: Runs the Builder server.
The pool
and builder
commands will also start a gRPC endpoint to allow other processes to interact with each service.
These options are common to all subcommands and can be used globally:

Private keys for the bundler can be provided in a few ways. You can set the --builder.private_key
flag or the BUILDER_PRIVATE_KEY
environment variable
within your local or deployed environment. Alternatively, you can provide the application with one or more AWS KMS ids using the --builder.aws_kms_key_ids
flag or AWS_KMS_KEY_IDS
environment
variable. Rundler will download the key/s so long as you have kms:DescribeKey
& kms:Decrypt
IAM access to the KMS resource.
When using KMS keys, a Redis URL must be provided to Rundler which will take care of key leasing to make sure keys are not accessed at the same time from concurrent processes.
Here are some example commands to use the CLI:
# Run the Node subcommand with custom options
$ ./rundler node --network dev --disable_entry_point_v0_6 --node_http http://localhost:8545 --builder.private_keys 0x0000000000000000000000000000000000000000000000000000000000000001
# Run the RPC subcommand with custom options and enable JSON logging. The builder (localhost:50052) and pool (localhost:50051) will need to be running before this starts.
$ ./rundler rpc --network dev --node_http http://localhost:8545 --log.json --disable_entry_point_v0_6
# Run the Pool subcommand with custom options and specify a mempool config file
$ ./target/debug/rundler pool --network dev --max_simulate_handle_ops_gas 15000000 --mempool_config_path mempool.json --node_http http://localhost:8545 --disable_entry_point_v0_6
