Hyperliquid has expanded its HIP-1 token standard with a new scaleWei function that lets a token's deployer proportionally adjust every holder's balance in a single atomic transaction — the on-chain equivalent of a stock split, but built to also handle dividends, airdrops, repricing events and reverse splits through the same mechanism. According to Hyperliquid founder Jeff Yan, the goal is to let deployer-controlled tokens absorb the kind of corporate actions that have historically required separate migration contracts or manual claim processes.
Under the updated HIP-1 specification, when a deployer triggers scaleWei, every balance of the referenced token is rescaled at once, with no user action required and no fragmentation of liquidity between old and new token versions. Open orders sitting on Hyperliquid's order book for that token are automatically recalibrated as part of the same operation, so a limit order doesn't become nonsensical the moment a 2-for-1 split executes.
Built with tokenized stocks in mind
Access to scaleWei is restricted to two categories: system addresses and signed vaults, meaning only a token's original deployer or an authorized vault structure can trigger a balance-scaling event — a guardrail against arbitrary rebasing by unrelated parties. The feature arrives as Hyperliquid's HIP-3 framework, live since October 2025, has opened perpetual futures listings to outside builders and brought tokenized stocks, commodities and indices onto the platform at meaningful scale, giving deployers of tokenized equities a native way to mirror real-world corporate actions like splits and dividend payouts without leaving the chain.
Closing a gap between tokenized assets and their real-world counterparts
The update addresses a structural weakness in most tokenized-asset designs: a token meant to track a real stock's price typically has no built-in mechanism for handling that stock's split or dividend history, forcing issuers to either ignore corporate actions or bolt on custom logic. By making scaleWei a native part of the HIP-1 standard rather than a per-token workaround, Hyperliquid is positioning its token framework as infrastructure other builders can rely on as tokenized equities expand across the platform.

The change is incremental from a user's perspective — most holders will never trigger scaleWei themselves — but it removes one of the more awkward gaps between tokenized securities and the traditional shares they're meant to represent, at a moment when tokenized-stock volume across the industry continues to grow.
