This is the piece that closes the trilogy. The most complete of the three, and by far the most insightful. When @TuomHolmberg took our call after my second article, he asked for one thing. Not an apology, but that accurate data reach the community. This piece is that request taken literally. Built on 5.97m confirmed rips from @Collector_Crypt's API, the platform's full history from April 2025 through this week. Fact-checked by the team, conclusions are mine. Enjoy

For Hyperliquid, this is an obvious net positive. If the profit share is similar, the reserve yield base expands ~50x ($100m USDH vs ~$5b USDC). It also removes an obvious UX problem. Fragmentation between $USDH and $USDC was always awkward. Traders want one dominant collateral and quote asset. Builders want liquidity. Market makers want inventory simplicity. For HIP-3 deployers, the impact is...more mixed. It creates a harsher Darwinian environment. Once everyone has the same aligned $USDC economics, deployers that used $USDH as strategic differentiation can no longer lean on quote asset selection as their wedge. They now have to compete on markets, liquidity, frontend, distribution, incentives, and community. So for $USDH native HIP-3 deployers, this is a headwind to differentiation but a tailwind to addressable liquidity. $USDH gave them alignment, but it also came with friction. Traders had to bridge, convert, hold a less familiar stablecoin, and deal with thinner secondary liquidity. Traders do not care about ecosystem alignment if the book is thin, the quote asset is inconvenient, and the conversion path is annoying. In that environment, the benefit was abstract while the friction was immediate. So the question boils down to whether $USDH was helping them win traders, or mostly explaining why they had not won traders yet.
