This will start a Multiversx Snapshotless Observing Squad.
The snapshotless mode allows you to quickly syncronize with the network. You can use it to quickly get address, balance, vm-query, esdt and nft information.
In order to integrate with the MultiversX Network and be able to broadcast transactions and query blockchain data in an optimized approach, one needs to set up an on-premises Observing Squad. An Observing Squad is defined as a set of N Observer Nodes (one for each Shard, including the Metachain) plus an MultiversX Proxy instance which will connect to these Observers and provide an HTTP API (by delegating requests to the Observers).
The snapshotless mode allows you to quickly synchronize with the network and perform Rest API calls for retrieving real-time data from the blockchain, such as getting data of an address (GET /address/${address}), getting the balance of an address (GET /address/${address}/balance), sending transactions, performing Smart Contract Queries and many more .
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
This listing has one pricing dimension. You run the Snapshotless Observing Squad on a t3a.2xlarge instance, billed by the hour. The software itself is free, so you pay only for the hourly compute time you use. Snapshotless observers connect to the network and serve real-time data requests without performing costly historical trie operations. There are no tiers, quantity commitments, or add-on options to choose between. Your cost scales directly with how many hours the instance runs.
Top-of-mind questions for buyers
What does the t3a.2xlarge hourly rate cover, and am I charged when the instance is stopped?
You pay for each hour the t3a.2xlarge instance runs. The software itself is free, so charges reflect only the underlying compute time. When you stop the instance, hourly compute charges stop too. Note that attached storage may still incur separate AWS storage fees while stopped.
What does a snapshotless observer do, and what data can it serve compared to a regular node?
A snapshotless observer connects to the network and serves real-time data requests. It skips costly historical trie operations like snapshots. This means it can return current address balances, nonces, tokens, and network status, but it cannot serve historical queries such as past block states from earlier dates.
Does running this observer require staking EGLD or earn network rewards?
No. Observer nodes do not participate in consensus and do not earn rewards. Only validator nodes require a stake and qualify for rewards. This observer supports the network by serving data requests, so you pay only the hourly compute cost with no staking commitment.

An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Beta release of Snapshotless Observing Squad
Upgraded to latest version of Ubuntu 24.04
Additional details
Usage instructions
For ssh access please use user ubuntu.
The Multiversx Observers squad is started by a systemd service that triggers a docker compose command.
We are running an experimental UI based on OliveTin. You can connect to it at http://<ec2 instance ip>:1337/login
The default credentials are: mvx/mvx
There are several tools to help you check the status of the deployed squad.
The same tools are available on the server at this path: /opt/multiversx-observing-squad-tools/
Make sure to allow port 22 and 8079 in your security group settings if you're planning to make the api calls over the internet (ufw allow 8079).
curl -s -k <yourip>:8079/network/config
AWS Support is a one-on-one, fast-response support channel that is staffed 24x7x365 with experienced and technical support engineers. The service helps customers of all sizes and technical abilities to successfully utilize the products and features provided by Amazon Web Services.
This will start a Multiversx Full Observing Squad.
The full mode will download existing snapshots and then start synchronizing with the network. You can use it to get address, balance, vm-query, esdt and nft information.
