Robinhood Crypto's official X account @RobinhoodCrypto posted to publicly welcome a relatively niche ecosystem protocol, @metricxyz. Pretty rare to see this happen. The fact that Metric got this kind of recognition, in my opinion, is closely tied to its highly aligned positioning with RH Chain and its ability to strengthen key underlying infrastructure. Metric positions itself as a DEX based on the propAMM mechanism, but it’s not in zero-sum competition with the leading DEX on RH Chain, Uniswap. Instead, it aims to further expand the overall pie of the spot market. The propAMM mechanism is different from traditional AMM: traditional AMM can be understood as "trade first, then let the price adjust based on trades," while Metric is more like "bring in the real price first, then trade around it." The former is particularly suitable for assets without external reference prices and long-tail markets, while the latter is very friendly for assets like RWA (real-world assets) or tokenized stocks that have real external market prices. Under the propAMM mechanism, asset prices are primarily driven by external reference prices introduced via oracles. This allows asset prices to quickly follow real price movements, making prices more accurate, reducing LP risks, and improving capital efficiency. With Metric onboard, it can form a clear complementary division of labor with Uniswap: Uniswap provides foundational and general liquidity, while Metric offers specialized liquidity for stock tokens. Together, let’s grow and strengthen the Robinhood Chain ecosystem.
