Got my husband @wwarren (cofounder of 0x/Matcha, building in crypto 8+ years) to do a builder's AMA on Farcaster, starting in 10 min. Will share the thread soon once he posts, feel free to share any questions here in the meantime you want to ask him

Hello, feel free to AMA about 0x, Matcha, building on Ethereum, etc!

what’s the hardest thing for users to understand

That the sticker price you see in the UI isn't necessarily what you'll get in your wallet once the swap tx is mined. 

And since meta-aggregators like DefiLlama rank quotes based on sticker price, it creates really bad incentives

you probably don’t think about liquidity enough // it is what it is  // build value, not valuation

Curious what specifically is wrong with Llamaswap’s calculations?

DEX aggregator APIs often return quotes that are based on a stale snapshot of blockchain state and the llamaswap UI does not validate the quote, ensuring the sticker price is accurate and achievable onchain.

Not all. Most DEX Aggregator APIs can return a quote in less than the block time. The image below shows a snapshot of DEX Aggregator API latency on Base sometime during February. (v2 is 0x)

The issue arises when routing is performed on a stale snapshot of blockchain state. Then the quote can be quite stale.
