Robinhood Chain TVL is still climbing. As of today: DeFi TVL just under $1B, up sharply over 30 days π
According to @DefiLlama:
β Bridged TVL: $3.16B
β Stablecoin cap: $1.04B
β DEXs volume (24h): $1.5B

The mix shifted by TVL. @Morpho and @SteakhouseFi now lead TVL ($555M and $511.5M), not the memecoin terminals that drove the July spike. Lending and asset management are now 63% of TVL.
Revenue tells a different story: @gmgnai and @ponsdotfamily still out-earn every DeFi app on the chain combinedπ°

Continuing @HyperliquidX Under the hood π
Part 5: agent wallets and the nonce state machine
Share one agent key across two workers, and a same-millisecond race produces duplicate nonces. int(time.time() * 1000) will not catch it.

On Hyperliquid, serialization is the security boundary, not metadata.
β reorder a dict field
β write "0.0010" instead of "0.001"
β add a vaultAddress
Any one of these changes the signed connection ID.
