Notes

  • Clockwork is under active development. All interfaces and implementations are subject to change.
  • Official program deployments to Solana Mainnet programs are secured by a 2-of-2 multisig and managed by a core team of maintainers.
  • On Solana mainnet, Clockwork automations are powered by a permissionless network of independent node operators. To join the workernet, you can install the Clockwork geyser plugin and request an earlybird token delegation in the workernet channel on Discord.
  • Occassionally, a new release may change the state schema and require users to migrate to a new program. These releases will be marked by a new major version upgrade (e.g. v2.x, v3.x, etc.).
  • The smart-contracts in this repository are automatically scanned by Sec3's auto-auditing software and are currently being reviewed by the team at Ottersec. Their audit report is in progress and will be published soon.

Getting Started

Local Development

1. Download the source code.

git clone https://github.com/clockwork-xyz/clockwork
cd clockwork

2. Checkout the latest stable release branch.

git describe --tags `git rev-list --tags --max-count=1`
git checkout tags/...

⚠️ Make sure the version of your program or client matches the version of the engine that you are running. E.g., if you are using clockwork-sdk = 2.0.0, you should also git checkout tags/v2.0.0. We use semantic versioning, but main branch is probably not what you want.

3. Build the repo.

./scripts/build-all.sh .
export PATH=$PWD/bin:$PATH

4. Start a localnet for development.

clockwork localnet

5. Stream program logs.

solana logs --url localhost

Deploying a worker

1. Either build from scratch (see above) or install the pre-built binary.

curl -s https://api.github.com/repos/clockwork-xyz/clockwork/releases/latest | grep "clockwork-geyser-plugin-release-x86_64-unknown-linux-gnu.tar" | cut -d : -f 2,3 | tr -d \" | wget -qi -
tar -xjvf clockwork-geyser-plugin-release-x86_64-unknown-linux-gnu.tar.bz2
rm clockwork-geyser-plugin-release-x86_64-unknown-linux-gnu.tar.bz2

2. Next, create a new keypair for signing Clockwork txs.

solana-keygen new -o clockwork-worker-keypair.json

3. Load this keypair with a small amount of SOL (~0.1 ◎).

4. Register your worker and get a worker ID:

clockwork worker create clockwork-worker-keypair.json

5. Setup the plugin config file.

{
  "libpath": "/home/sol/clockwork-geyser-plugin-release/lib/libclockwork_plugin.so",
  "keypath": "/home/sol/clockwork-worker-keypair.json",
  "rpc_url": "http://127.0.0.1:8899",
  "transaction_timeout_threshold": 150,
  "thread_count": 10,
  "worker_id": 0, 
}

6. Configure your validator to run with the Clockwork plugin.

#!/bin/bash
exec solana-validator \
  --identity ~/validator-keypair.json \
  --rpc-port 8899 \
  --entrypoint entrypoint.devnet.solana.com:8001 \
  --no-voting \
  --full-rpc-api \
  --limit-ledger-size \
  
  # Add this line! 👇🏼
  --geyser-plugin-config ~/clockwork-geyser-config.json

7. Restart your validator however you normally would!

sudo systemctl restart sol
