Node configuration

Prerequisites

• Operating system: MacOS(x86 intel chip) or Ubuntu (tested on 18.04).
• Hardware: 4 cores, 8-16GB RAM, 512 GB drive, arm64 or amd64. Recommended 6-8 cores, 16-32 GB RAM, 1 TB+ drive.
• Increase the maximum number of open files on your system. Example: ulimit -n 16384. You may wish to add this command to your shell profile so that you don't need to execute it next time you restart your machine.
• CLI configuration.

Download binaries and initialize configuration

Clone the axelerate-community (opens in a new tab) repo:

git clone https://github.com/axelarnetwork/axelarate-community.git
cd axelarate-community

Run setup-node.sh to download the axelard binary and configure your node:

./scripts/setup-node.sh -n [mainnet|testnet]

Some additional flags:

• -a : Version of axelard.
• -d : Home directory path.
• --help : Print a complete list of flags.

Verifying Binaries

By default, the binary signatures are downloaded and the binary is verified using the axelardev (opens in a new tab) PGP key. To verify the binary manually, you can download the PGP signature and verify using the following commands:

curl https://keybase.io/axelardev/key.asc | gpg --import
gpg --verify [axelard_binary_signature_path] [axelard_binary_path]

On github the signatures are attached to the releases. To download the signatures from the axelar-releases AWS Bucket, you can add .asc to the end of the binary URL. For example, if the path of the binary is:

https://axelar-releases.s3.us-east-2.amazonaws.com/axelard/v0.26.0/axelard-darwin-arm64-v0.26.0

The path for the signature will be:

https://axelar-releases.s3.us-east-2.amazonaws.com/axelard/v0.26.0/axelard-darwin-arm64-v0.26.0.asc

Home directory

By default the setup-node.sh script sets the home directory for your node as follows:

On a fresh install setup-node.sh puts the following in your node's home directory:

.axelar

│   ├── axelard -> /Users/gus/.foo/bin/axelard-vx.y.z
│   └── axelard-vx.y.z
