Elysium testnet is live on Quicknode. @Kinetiq_xyz built @Enter_Elysium as an L2 on top of HyperEVM, giving Hyperliquid apps one more place to build, with everything settling back home. Stoked to be a day 1 partner for the upcoming mainnet 💪🔽

opus 5 is terrible, it seems like anthropic made it extra verbose so they can get their token usage numbers up. extra tool calls for stuff thats already in the context window, etc have switched to codex after being a claude maxi for a while

the ux of @cursor_ai opening "agent" mode instead of the IDE is terrible

I know this looks like a cute pixel game, but it's actually a real-time @HyperliquidX mempool Pending txs are cats 🐱 waiting on the pier; blocks are boats 🛥️. When your tx confirms, your cat literally sails away Live: txharbor.com (🔉on, trust me)

New to @Quicknode Earn? This is how you create a strategy for self-custodial yield automation. Every configuration, what it does, and why it matters. A thread: 1/12

You didn't get into crypto to babysit an indexer. Reorgs, backfills, schema migrations at 3 am. So we took it off your plate. Bitcoin ordinals, Solana NFTs, 500B rows of Hyperliquid trades, onchain AI-agent reputation. Each one a brutal job. We did them all. You just query.

Polling the chain in 2026 feels like hitting refresh on your inbox every few seconds, just in case something new came in. Hit endpoint. Wait. Hit it again. Handle the rate limits. Dedupe. Hope you didn't miss a block. We got tired of that, so we built the opposite: real-time data, pushed to your stack the second it happens, on every major chain.

Gearing up to launch @quicknode Earn, an automated, self-custodial, automated yield rebalancer that moves you in/out of different listed @morpho vaults to fetch you the best APY on your USDC. Closed beta opened late last week. If you're wanting to test and shape the product in its infancy, I want to work with you. Check it out 👇 earn.quicknode.com

Quicknode Earn: Automated USDC yield across Morpho vaults

Non-custodial USDC yield across curated Morpho ERC-4626 vaults on 7 chains. Earn moves your USDC to the highest-yielding eligible vault. APY is variable.

One readable JSON body. Four calls. A resting order on @HyperliquidX No msgpack, no EIP-712 by hand, no nonce tracking. See it against the raw API in the video. 👇
