Collator Requirements

How to become a collator

Permissionless collator

To become a permissionless collator on our networks, you need to meet the requirements below.

Collator staking requirements

  • Bond: 3,200,000 ASTR tokens (3.2M $ASTR)
  • Meet hardware requirements

If your node stops producing blocks for 1 session, your node will be kicked out of the active set and 1% of the bonded funds will be slashed. Running a node with low performance can lead to skipping blocks which may result in being kicked out of the active set.


Set your collator with: Extrinsics - CollatorSelection - Register as candidate | Onboarding takes n+1 session.

System requirements

A collator deploys its node on a remote server. You can choose your preferred provider for dedicated servers and operating system. Generally speaking, we recommand you to select a provider/server in your region, this will increase decentralization of the network. You can choose your preferred operating system, though we highly recommend Linux.

Hardware requirements

Use the charts below to find the basic configuration, which guarantees that all blocks can process in time. If the hardware doesn't meet these requirements, there is a high chance it will malfunction and you risk be automatically kicked out and slashed from the active set.


Make sure your server is a bare metal only dedicated to the collator node, any unnecessary other process running on it will significantly decrease the collator performance. We strongly discourage using a VPS to run a collator because of their low performances.

Collators are the nodes which require the most powerful and fast machine, because they only have a very short time frame to assemble a block and collate it to the relay chain. To run a collator, it is absolutely necessary to use a CPU of minimum 4 Ghz per core and a NVMe SSD disk (SATA SSD are not suitable for collators because they are too slow).

Hard Disk500 GB SSD NVMe

Shibuya is the perfect network to test out your knowledge about running nodes in the Astar ecosystem. To join the collator set on Shibuya you need to apply for a 32k SBY fund. If you never operated a collator node, we strongly encourage you to spin up a Shibuya collator node to start before thinking about mainnet. A perfect start is our secure setup guide.
