re: XCU (Copper)

To maintain parity with other venues, we are updating the XCU (Copper) underlying from the spot price methodology previously used to a rolling futures-based methodology, effective immediately.

The documentation has been updated accordingly and can be found here

- Support for maker-only api keys per L1 has been increased from 200 to 251 per account_index

- Whitelisted operators can now create up to 6 public pools per L1

- The last_updated_at field on the ticker WebSocket channel now always reflects the latest transaction_time impacting the best bid & offer

Fast withdrawals are now limited at ten per hour per address. If that creates any operational issue, you can contact us via Discord support.

Story Protocol ($IP) has been renamed to Data Network ($DATA). This is a rebrand only and does not affect the underlying market. The update will be reflected across the Lighter frontend and backend tomorrow, June 30, at 11:00 AM UTC.

On the API side, updates will be delivered as DATA starting at that time, while the market ID remains unchanged. No action is required.

- The export endpoint now allows to aggregate trades: https://apidocs.lighter.xyz/reference/export

- We're removing internal price caps for the below markets before today's market close. To prevent price manipulation attacks, we are going to monitor other liquid venues and cap the price in case of a manipulation attempt. For the other markets, no changes apply.

- mark_price and index_price have been added to the orderBookDetails endpoint: https://apidocs.lighter.xyz/reference/orderbookdetails

- Front-end now allows editing multiple api keys at once to toggle maker-only status: https://apidocs.lighter.xyz/reference/apikeys. For latency-sensitive traders we strongly recommend their usage, more details can be found here: https://apidocs.lighter.xyz/docs/api-keys#maker-only-api-keys

- The positionFunding endpoint now accepts a market_ids query parameter, which can contain a list of market indexes separated by commas: https://apidocs.lighter.xyz/reference/positionfunding

- The fundings endpoint caching has been improved, fixing some edge cases where the last funding payment was showing up as empty: https://apidocs.lighter.xyz/reference/fundings

These changes apply to both Lighter Core, and the Robinhood Chain instance (https://apidocs.rh.lighter.xyz/).

- We have released v1.0.7 of the Lighter Go SDK. Release notes are available here: https://github.com/elliottech/lighter-go/releases/tag/v1.0.7

- The remaining_usage field will not be returned anymore by the referral/get and referral/create endpoints, starting Monday, Jul 27th. Currently, both Lighter Core and the RHC instance allow for unlimited invites

We will be performing a network upgrade on August 9, 2026 at 1:00 PM UTC. Expected downtime is under 15 minutes.

Please manage your positions in advance, as order placement will be unavailable during the upgrade.

To market makers: Lighter on Robinhood Points will go live on Thursday, August 13 at 4 PM UTC.

Connecting to the Robinhood instance is straightforward since the architecture is the same as Lighter Core. The only difference is the API URL you connect to.

USDG from Paxos is the main stablecoin used as collateral. Tokenized SPY and USO are also available to use as collateral, which can be sourced in Lighter on Robinhood Chain.

API Docs: https://apidocs.rh.lighter.xyz/

The RHC instance incentives campaign has started: https://t.me/lighter_announcements/392. Note that points will accrue both live, and via a weekly distribution. Builders that wish to display on their apps points accrued by their clients can do so using the following:

• leaderboard endpoint, showing totals (both live, and weekly distributions). Use type=all, as weekly granularity is not supported: https://apidocs.rh.lighter.xyz/reference/leaderboard. If you don't authenticate the request, only top addresses in the leaderboard will be returned

• livePoints/total endpoint, returning only the live portion of points: https://apidocs.rh.lighter.xyz/reference/livepoints_total

• live_points WebSocket channel, to stream live points updates: https://apidocs.rh.lighter.xyz/reference/livepoints_total

Builders that wish to bind their referral code programmatically, as a client signs-up to lighter via their app, can do so via the referral/use endpoint: https://apidocs.rh.lighter.xyz/reference/referral_use. Note that on our RHC instance, an account earns 10% of the points earned by the users they refer.

We will be performing scheduled maintenance for https://robinhoodchain.lighter.xyz on Friday, August 21 at 11:00 AM UTC. Expected downtime is under 15 minutes.

Please manage your positions in advance, as order placement will be unavailable during the maintenance.

You can also subscribe to https://robinhoodstatus.lighter.xyz to receive notifications and updates.

Builders can now leverage https://fun.xyz/ routes to deposit to Lighter Core programmatically. Initially, USDC and ETH (which is swapped to USDC) are supported as deposit assets, from 15 chains. Full implementation details are available here: https://apidocs.lighter.xyz/docs/deposits-transfers-and-withdrawals#deposit-via-funxyz

Each builder will be issued an api key to be used in headers. You can reach out via the #support channel on Discord including details on your project to receive one: https://discord.gg/lighterxyz

Currently, the integration is enabled on Lighter Core, with plans on expanding it to the Robinhood Chain instance in the near future. Support for withdrawals is also planned.

If you're a market maker interested in participating in Lighter's RFQ flow, you can find the integration docs here. We expect RFQ flow to increase meaningfully now that the feature is open to all traders.

Advanced Order Fee Update

As a reminder, Standard accounts will now have a 0.01% (1 bp) fee on RFQ, Chase Limit, and TWAP orders.

Plus and Premium accounts will continue to have their normal tier fees.

Limit and Market orders remain free.

The following changes have been deployed to both Lighter Core, and the Robinhood Chain instance:

• An order_version parameter can now be specified when modifying an order, with both available SDKs supporting it. This guarantees correct ordering, where the sequencer will reject any version that is not strictly greater than the order's current stored version, returning AppErrInvalidOrderOrderVersion.
• Order events now include order_version
• Trade events now include ask_order_version, bid_order_version

The above remains optional, and existing workflows will not break. Examples on how to use order_version are available here (http) and here (ws)

The following changes have been deployed to Lighter Core:

• sendTx/sendTxBatch rate limits for the best premium tier have been increased by 20%, now at 48,000 transactions per minute
• Trades executed through the partner attribution program, with non-zero integrator fees, will not be considered for kickbacks and rebates: https://docs.lighter.xyz/referral-program

The following change has been deployed to the Robinhood Chain instance:

• Volume tier thresholds (which determine rate limits for premium accounts) have been temporarily lowered, requiring $500M volume in the last 14 days to access the best tier: https://apidocs.rh.lighter.xyz/docs/account-types. Thresholds will be adjusted upwards as venue activity increases
