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 combinedπŸ’°

Ethereum and Tron still hold about 80% of all stablecoin supply. Sending USDT or USDC still means holding ETH or TRX for gas. Four L1s are trying to change that: @tempo, @Stable, @arc, and @Plasma. Each one bets on a different actor, not a different feature.

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.

Every worker using the same Hyperliquid agent key shares one nonce set, no matter which account it targets: β†’ master order β†’ sub-account order β†’ vault cancel All three draw from the same pool. Allocate per account instead of per signer, and you hit the wrong set.

Arc Mainnet is live. Arc launches as the Economic OS for the internet: an open platform for global markets, real-time value movement, tokenized assets, and agentic economic activity. Arc is more than a blockchain. It launches as a full-stack financial platform with assets, applications, interoperability, developer infrastructure, and Circle platform services live from day one. Arc delivers USDC as native gas, deterministic sub-second finality, EVM compatibility, and institutional validators. It integrates with Arc Studio, App Kits, Arc Portal, Circle Agent Stack, CCTP, Gateway, CPN, and StableFX. A complete economic platform at genesis. Arc launches with infrastructure for: β†’ Agentic economic workflows β†’ Lending and borrowing β†’ Trading and liquidity β†’ Onchain FX β†’ Payments and settlement β†’ Tokenized assets β†’ Exchanges, wallets, custody, compliance, data, and developer tooling 190+ institutional and ecosystem builders are building across Arc.

Fomo (@fomo) is a cross-chain social trading app that deploys no contracts of its own. The onchain footprint is ERC-4337 wallets, Relay settlement contracts, and ordinary AMM pools on @solana and Robinhood Chain. We mapped that footprint and shipped listeners for the full trade flow. The Robinhood side uses the same sequencer feed.

Robinhood Chain (@RobinhoodCrypto) has no public mempool. A tx is invisible until the sequencer orders it. RPC, explorers, and indexers still have to re-execute the block before they can tell you what happened. The decoder reads the feed directly: hash, kind, target, selector.

That control starts with an ID. Every HIP-3 market gets a real HyperCore asset ID, not just a display name. asset = 100000 + perpDexIndex Γ— 10000 + indexInMeta On testnet, `test:ABC` is 110000.

Fees are the first surprise. Consensus is the second. StableBFT is live: ~0.7s blocks, final the moment a tx is included. No reorg window. Autobahn is the DAG successor promising ~5x more throughput. Still on the roadmap, not production.

Most payment chains still charge gas in a token that moves with the market. Settlement cost tracks that chart. @Stable is a payments L1 backed by @bitfinex. USDT0 is the gas token ⛽️

Writes don't work like a normal contract call ⏱️ CoreWriter emits an action. HyperCore processes it after the EVM block, not inside it. β†’ Limit order price and size: 10^8 * human value, not the read-side scaling β†’ Order actions are delayed a few seconds on purpose: no latency shortcut around the mempool β†’ sendRawAction doesn't revert on a dropped action. Your EVM tx still succeeds.

Precompiles aren't normal Solidity functions πŸ”’ β†’ No function selector: staticcall with raw ABI-encoded args only β†’ oraclePx returns raw integers: human price = raw / 10^(6 - szDecimals) β†’ BTC at szDecimals 5: raw 631381 becomes 63,138.1, not 631,381 Assume 1e8 scaling everywhere and you'll silently misprice assets.

Continuing @HyperliquidX Under the hood πŸ”Ž Part 3: how Solidity actually touches HyperCore state. β†’ Precompiles: read HyperCore state inside an EVM call, no oracle, no off-chain relay β†’ CoreWriter: emit an action, HyperCore validates and executes it after the EVM block HyperEVM doesn't simulate HyperCore. It reads and writes to the real thing. 🧡

Spot and Perp are only half the isolation story πŸ”’ Sub-accounts aren't a UI toggle. Each one is its own address with its own `clearinghouseState` and `spotState`, no private key of its own. A liquidation on one can't touch another's balances. Up to 10 sub-accounts once the master crosses $100K in volume

Continuing @HyperliquidX Under the hood πŸ”Ž Part 2: why market makers can quote at the edge instead of pricing in re-org risk. β†’ @ethereum & rollups: submit, wait, hope no re-org β†’ HyperBFT: one-block finality, ~100ms, no re-orgs possible That's the deterministic floor everything else on Hyperliquid builds on.

Four facts about the @arc stack: β†’ Reth for execution, Malachite (BFT engine from Informal Systems) for consensus β†’ ~0.5s blocks, deterministic finality, no reorgs β†’ Mainnet chain ID 5042, testnet 5042002, don't mix them up β†’ USDC pays gas at 18 decimals, reads as an ERC-20 balance at 6

669M+ transactions and 49M+ addresses on the @arc testnet, before mainnet has even shipped. @circle is launching this L1 with USDC as the native gas token, and a founding validator set that reads like TradFi: @BlackRock, @Mastercard, @Visa.

Full breakdown of Clearinghouse, Agent Keys, and cross-margin architecture by @AndreyObruchkov, Part 1 of the series ‡️ chainstack.com/hyperliquid-a…
29
Cross-margin on most DeFi: borrow against BTC, bridge to a perp DEX, deposit into their vault. Multiple contracts, multiple failure points. On Hyperliquid, the Clearinghouse is the L1's state tree itself. Spot and Perp read as one account: `crossMarginSummary.accountValue` Everything lives in one account.

Starting a series: @HyperliquidX Under the hood πŸ”Ž Part 1: why the order book can't live inside a smart contract. β†’ @ethereum & EVM rollups meter gas per opcode: 1,000 quotes/sec means a latency tax every tick. β†’ @solana Sealevel parallelizes accounts, but every trader hits the same market PDA, collapsing into one lane. HyperCore skips both: order book logic baked into validator software, no VM in the critical path.
