# Hyperliquid fee and protocol change log (2026) > Dated Hyperliquid fee, referral, trading, API and protocol source reviews, plus material changes to this site’s calculations and risk disclosures. Canonical HTML: [Hyperliquid fee and protocol change log (2026)](https://hyperliquidreferralcodes.com/updates) Markdown URL: [Hyperliquid fee and protocol change log (2026) as Markdown](https://hyperliquidreferralcodes.com/markdown/updates.md) Reviewed: 19 Sept 2026 (2026-09-19). Bottom line: The 19 September 2026 update adds a longer second order-book collection while preserving the original data, method and collection dates. ## 19 September 2026 · a second dated data collection Added 60 rounds of public BTC, ETH, SOL and HYPE order books at planned 15-second intervals: 240 additional snapshots and 1,440 modeled order scenarios. The earlier 24-snapshot collection remains unchanged. Each window has separate results and downloads; the unsampled time between collections is not treated as observed data. Published a capture attempt journal and extended the offline reproduction program to accept a collection date. The sample still does not establish representative daily liquidity, executed trades or connected-account referral acceptance.

The study includes raw JSON, CSV results, calculation source and an offline reproduction script. One scenario lacked sufficient visible depth and receives no cost estimate. The results describe modeled fills from a short sample, not executed trades or a representative liquidity ranking. Checked the staking referral proposal’s official status notice. Separated its unimplemented design from standard referrals and discounts from a trader’s own HYPE staking. Added linked guidance on 30%, 35% and lifetime claims, a matching FAQ and a source-check guard for the proposal’s status. Account acceptance and third-party cashback remain outside our published verification. A second review corrected HYPE collateral LTV to 0.65 and clarified variable TWAP intervals with a 30-second minimum. The margin guides now distinguish the maintenance rate from the amount after tier deductions. Added regression checks for these claims. Small cost estimates now retain fractional cents. Improved mobile menu dismissal and calculator error labels. Source checks run with the release checks; they cover selected claims and do not replace editorial review. A random-code control showed that the public invite displays supplied URL text. We corrected earlier wording that treated this as code recognition. Connected-account acceptance and realized savings remain unconfirmed by our published evidence. The standard cost calculator now rejects malformed input, separates spot sell-side builder charges and makes long/short funding direction explicit. It labels unsupported products and refuses to estimate partial eligibility across the referral-volume limit. Rechecked Aster’s contract-group labels and retained the documented conflict between its fee page and overview. Reorganized the referral page around terms, a dollar-savings example and activation help. Added code copying, visible independent identity on mobile and keyboard access to wide data tables. ## 12 August 2026 · AI discovery and AWD verification Added current crawler rules for documented search, user-requested and training agents. Added generated llms.txt v2 discovery and a Markdown version of each public guide. Added stable publisher and author provenance, official citations for the calculators, and stricter checks for metadata, crawler access, machine-readable content and 404 pages. Recorded the public AWD invitation. The original description treated this as recognition; the 18 September control test corrects that interpretation. The historical observation did not establish account acceptance. ## 11 August 2026 · search and content release Added the Google Search Console pipeline for property discovery, content catalog generation, performance sync, URL inspection, and analysis of search opportunities. Improved the core guide content and comparison pages. Repaired internal links so the referral, fee, trading, margin, review, alternative, and risk paths connect to their next useful guide. Changed guide reading times to use computed values from visible content and added checks for related routes. Added a position-size calculator that uses risk budget, entry, stop, execution reserve, leverage, and available collateral. ## 28 July 2026 · ranking and comparison release Re-ran the monitored-source suite, formula tests, security audit, metadata checks, sitemap crawl, canonical checks, content-depth checks and production build after the ranking audit. Separated the homepage referral intent from the activation guide. Strengthened the fee calculator and market-data landing pages. Added Organization and WebApplication structured data. Published primary-source comparisons for Lighter, dYdX and Aster. Added official comparison sources to the source-check script. Clarification on 18 September: the script flags covered claims when run. It does not establish continuous monitoring or detect every upstream change. ## 27 July 2026 · research and product rebuild Rechecked referral eligibility, fee and staking tiers, funding mechanics, current onboarding routes, order types, liquidation, HyperCore, HyperEVM, staking, vault, risk and API documentation. Added Market Pulse using metaAndAssetCtxs, with derived USD OI and impact-spread methodology. Added a round-trip calculator and source-drift checker. Expanded the research library to cover account access, spot trading, cross and isolated margin, portfolio margin, subaccounts and HYPE utility. Added HyperEVM network setup, HIP-3 perps, HIP-4 outcomes, testnet, historical data and market-making guides. Documented the confirmed history of points programs. Updated the order guide for Chase orders and new TWAP controls, refreshed documented deposit routes, and added current HIP-3 growth-mode, aligned-quote and outcome-market fee distinctions. ## What earns an update entry We log changes that affect money, eligibility, risk, calculations, data units, canonical URLs or editorial independence. Minor typography and spacing changes are not listed. Each material change must pass formula, metadata, sitemap, internal-link and production build checks before deployment. ## Official sources - [Hyperliquid Docs: Referrals](https://hyperliquid.gitbook.io/hyperliquid-docs/referrals): Official source used for the product claims on this page. - [Hyperliquid Docs: Fees](https://hyperliquid.gitbook.io/hyperliquid-docs/trading/fees): Official source used for the product claims on this page. - [Hyperliquid Docs: Proposal: Staking referral program](https://hyperliquid.gitbook.io/hyperliquid-docs/referrals/proposal-staking-referral-program): Official source used for the product claims on this page. - [Hyperliquid Docs: Info endpoint](https://hyperliquid.gitbook.io/hyperliquid-docs/for-developers/api/info-endpoint): Official source used for the product claims on this page. - [Hyperliquid Docs: Portfolio margin](https://hyperliquid.gitbook.io/hyperliquid-docs/trading/portfolio-margin): Official source used for the product claims on this page. - [Hyperliquid Docs: Order types](https://hyperliquid.gitbook.io/hyperliquid-docs/trading/order-types): Official source used for the product claims on this page. - [Hyperliquid Docs: Margin tiers](https://hyperliquid.gitbook.io/hyperliquid-docs/trading/margin-tiers): Official source used for the product claims on this page. ## Related pages - [Methodology: sources, calculations and update policy](https://hyperliquidreferralcodes.com/methodology): Related guide. - [About Hyperliquid Field Guide: sources, funding and scope](https://hyperliquidreferralcodes.com/about): Related guide. - [Hyperliquid fees: maker, taker, spot and staking tiers](https://hyperliquidreferralcodes.com/hyperliquid-fees): Related guide. ## Publication details - Publisher: Hyperliquid Field Guide. - Status: Independent and unaffiliated with Hyperliquid Labs and the Hyperliquid Foundation. - Reviewed: 19 Sept 2026 (2026-09-19). - Affiliate disclosure: The site operator may earn protocol referral rewards when eligible users trade with code AWD.
