Testnet release notes and updates

We reset the Testnet as scheduled yesterday at 10am UTC (GMT+1) and released new versions of our node software and console.

A couple of the exciting improvements/fixes in v0.17.0 of the node software are:

  • Improvements to GraphQL APIs including a new allParties query.
  • Add an updatedAt field to all orders returned by APIs.
  • Return full Market details in nested GraphQL queries, previously this was just a summary.

Also, for a more in-depth summary of the changes in Console v0.22.0 head over to this post by @edd

Thanks and happy trading.


Thank you for the information, access requested. I really hope that you will invite me to the test team soon.
With respect MBGBuzzer [4Block]


Welcome @MBGBuzzer we hope to see you on a Testnet on boarding session soon :+1:


We reset the Testnet as scheduled today at 10am UTC (GMT+1) and released new versions of our node software and console.

A handful of the exciting improvements/fixes in v0.18.1 of the node software are:

  • Automatically build for multiple architectures and publish to GitHub releases.
  • Improvements to GraphQL APIs including support for governance proposals and complexity limits.
  • Fix amends triggering multiple updates to a single order in some use cases.
  • Fix to ensure keys are hex encoded.

For the Console v0.22.3 release:

  • Improvements to the toast notifications we added last release, and brings back the ‘Reset’ switch on the ‘loading page’. Useful if something goes wrong while loading. We hope you don’t need it, but if you do - it’s back.
  • Long public keys are now intelligently truncated.
  • Toast notifications now stack when they happen close together.
  • Fixes for logging in to a wallet with no keys present.
  • Other minor bug fixes/improvements.

We reset the Testnet as scheduled yesterday at 10am UTC (GMT+1) and released new versions of our node software and also Vega Console.

The v0.19.0 release of the node software contains many internal improvements, bug fixes and enhancements to pave the way for new Governance features.

For the Console v0.24.1 release, several enhancements that will support new Governance changes on Vega nodes. Additional fixes include:

  • Fix for incorrect title field on windows in new workspaces.
  • Fix for market order price showing as 0 in the order list.
  • Improved error messages given for login failure.
  • Font size changes for visual consistency.
  • Improve error handling and make reporting clearer.

:mega: We’ve performed our scheduled reset of the Testnet at 10am GMT (UTC), all your accounts will remain but your collateral and order book/positions will be removed and you’ll have a fresh set of collateral to play with! Happy trading :moneybag:


:mega: We’re about to reset the Vega Testnet to perform an update of the Market Names for our 3 test markets [MarketInfo->Instrument->Name], your trading collateral, positions and all orders will be reset as well. No other changes.


Our next Testnet reset and release is scheduled for Monday 3rd August at 10am UTC (GMT+1).

:rotating_light: EDIT: Sometimes big releases cause big bugs! This release has been rolled back. :rotating_light:

This time around we have a hefty update for the node software with release 0.22.0. The release primarily focuses on setting up Vega nodes to deal correctly with events sourced from other chains, as we’re nearly ready to start bringing in ERC20 assets from Ethereum. This includes responding to asset-related events from Ethereum, and support for validator nodes notarising asset movements and proposals. (Note: deposit of ERC20 assets on Vega is not yet enabled.)

The release also contains a lot of bug fixes and improvements, primarily around an internal refactor to use an event bus to communicate between packages. Also included are some corrections for order statuses that were incorrectly being reported or left outdated on the APIs.

Also new or improved:

  • Adding support for two-step governance processes such as asset proposals and new chain proposals, add RejectionReason field to rejected governance proposals, and add a new Notary package for tracking multisig decisions for governance, such as
  • Adding OpenInterest field to markets, which shows the total size of open orders
  • GraphQL: Orders will include their version and updatedAt, which are useful when dealing with amended orders
  • GraphQL: New asset proposals
  • API documentation: Improving order documentation for Status and TimeInForce

If you use APIs to interact with the testnet, these changes may affect you.

  • REST: Updating orders endpoints to use POST, not PUT or DELETE
  • GraphQL: Some endpoints returned a nullable array of strings. Now they will return an array of nullable strings
  • GraphQL & GRPC: Removing broken open parameter from Orders endpoints. It returned ambiguous results
  • REST & GraphQL: Market name will now be based on the instrument name rather than being set separately
  • Fixing outdated order details for orders amended by cancel-and-replace
  • Fixing incorrect status on partially filled trades that would have matched with another order by the same user. Was stopped, now rejected

The Console 0.27.2 release primarily includes design and usability improvements.

  • New design for how error messages are displayed
  • New design for the connection status, now appears in bottom left of browser window
  • Fixing various label typos and some improved labels
  • Fixing an issue where changing a pubkey wasn’t clearing the list of positions

Thanks @candida, as mentioned we’ve now rolled back this release so the testnet is fully operational running release 0.19.0.

We’ll update here as soon as we have the next release fixed, tested and ready to go :rocket:


Update: Testnet release 0.22.0 (Node software) and 0.27.2 (Vega Console) is now live and operating normally.

Happy trading, check out the new features listed two posts above and if you’d like to participate in our Testnet head over to our website to request access.


A Console-only update went out this evening, which fixed a long standing bug whereby old orders could show up in the Open Orders panel.

It was pretty disconcerting for users, but fortunately was ‘mostly harmless’. We were sometimes missing an update to an order, and that could include the fact that the order actually closed. It’s now displayibng as it should.


We’re doing a chain reset this morning, without an upgrade. It’s a new start for everyone!

Core 0.23.1
This release contains a lot of groundwork for Fees and Auction mode.

Fees are incurred on every trade on Vega. Those fees are divided between up to three recipient types, but traders will only see one collective fee charged. The fees reward liquidity providers, infrastructure providers and market makers.

  • The liquidity portion of the fee is paid to market makers for providing liquidity, and is transferred to the market-maker fee pool for the market.
  • The infrastructure portion of the fee, which is paid to validators as a reward for running the infrastructure of the network, is transferred to the infrastructure fee pool for that asset. It is then periodically distributed to the validators.
  • The maker portion of the fee is transferred to the non-aggressive, or passive party in the trade (the maker, as opposed to the taker).

Auction mode is not enabled in this release, but the work is nearly complete for Opening Auctions on new markets.

Please note, this release disables order amends . The team uncovered an issue in the Market Depth API output that is caused by order amends, so rather than give incorrect output, we’ve temporarily disabled the amendment of orders. They will return when the Market Depth API is fixed. For now, amends will return an error .(edited)

Console 0.31.2 - This release contains a lot of bug fixes, and improvements for upcoming functionality - specifically deposits from other chains and governance proposals. It also introduces a few changes to the default layouts. If you’ve experienced unclosable panels, or My Workspace not working, use the reset toggle in the settings menu to return to the defaults.

  • Replace existing Wallet menu with a new version based on Blueprint’s panel stack
  • Update default layouts to be 2 panels across the bottom, not 4
  • Remember custom column widths on tables
  • Reduce slow block sensitivity

Also, the API docs get a lot more information on each field in this release


Our next Testnet reset and release is scheduled for Monday 14th August at 10am UTC (GMT+1).

Release 0.24.0 includes a small update for the node software, it primarily focuses on bug fixes and improvements to existing features under the hood. This said, one new API endpoint has been added to allow cancelling of multiple orders simultaneously, either all orders by market, a single order in a specific market, or just all your open orders. Note: This is currently a gRPC/API Client only API method until the next release.

A minor power up that we’re adding in this release is rate limiting. We limit the number of transaction requests a party can make, using a simple but effective strategy for now.

Improvements have been made to our Reference API documentation with better descriptions for all fields.

:mega: We’re performing an earlier than scheduled reset and release of testnet today at 12pm UTC.

Node software updated to 0.25.0
This release adds the event bus API, allowing for much greater introspection in to the operation of a node. We’ve also re-enabled the order amends API, as well as a long list of fixes.

All your accounts will remain but your collateral and order book/positions will be removed and you’ll have a fresh set of collateral to play with! Happy trading :moneybag:

There are some breaking changes for the APIs with this release:

  • :fire: GraphQL, REST, gRPC: CumulativeVolume field has been removed from MarketDepth results and from 0.25.0 please retrieve all price levels and calculate a cumulative value on the client side using each volume value.
  • :fire: GraphQL: Field case change proposalId -> proposalID
  • :fire: GraphQL: Withdrawals now return a Party , not a party ID

We’re doing an out-of-usual schedule update to testnet at in 5 minutes. This is version 0.25.1, which is patch that contains:

  • Adds a REST endpoint prepareVote, which is much like the other prepareX endpoints, but for placing a vote,
  • Fixes a value that was being passed by reference rather than copied, which was the root cause of the Market Depth endpoint sometimes showing orders at price levels that were already closed

It’s a pretty boring batch release. The fun stuff is in 0.26.0 (which is oh-so-nearly tagged - event bus fixes and more) and 0.27.0 (price monitoring amongst others).
Those should come on our usually scheduled Monday release slots.

We’ve performed an update to the testnet alongside the scheduled reset today.

Node software updated to 0.26.1

This release provides extensive improvements to the Vega core and stability enhancements to the Events API and underlying events bus.

The Events API added in 0.25.0 had reliability issues when a large volume of events were being emitted. This release addresses that in two ways:

  1. The gRPC event stream now takes a parameter that sets a batch size. A client will receive the events when the batch limit is hit.
  2. GraphQL is now limited to one event type per subscription, and we also removed the ALL event type as an option. This was due to the GraphQL gateway layer taking too long to process the full event stream, leading to sporadic disconnections.

These two fixes combined make both the gRPC and GraphQL streams much more reliable under reasonably heavy load.

This release also adds some performance improvements to the way the core processes Tendermint events, some documentation improvements, and some additional debugging tools.

We’re performing an update to the testnet alongside the scheduled reset today at 10am GMT/UTC.

Node software updated to 0.27.0

This release contains improvements in the memory usage during auctions with particularly large order books. Previously this would cause slower block times when handling orders placed during an opening auction. The release also contains a lot of important internal work related to liquidity provision mechanics.

We have breaking changes for API client users, specifically #2476. When querying market data, previously all times were returned in seconds, they are now returned using RFC3339 format.

The testnet infrastructure will be undergoing maintenance upgrades at the same time as this release so please keep an eye on our Discord Testnet channel for the latest status on when the system will be returned to normal operation. :man_technologist:t2:


#2498 Automatically create a bond account for liquidity providers
#2596 Create liquidity measurement API
#2490 GraphQL: Add Withdrawal and Deposit events to event bus
#2476 :fire:MarketData now uses RFC3339 formatted times, not seconds
