if you've ever wondered:

• what an aggregator is
• what a meta-aggregator does
• why they're valuable, and who they help

Most people will skip this part
but this is where it gets interesting

thanks @spanDEXsh for the partnership 👏

had a blast chatting w/ @jchaskin22 and @binji_x from @ethereumfndn

we talked building (and pivoting!) in crypto the past 4yrs, improving onchain execution transparency, and open source DEX aggregation w/ @spanDEXsh

Wondering what a meta-aggregator, today's winner on @qrcoindotfun, is?

Read QR founder Jake's explanation on how they get the best swap quote:

[JAKE @0FJAKE]

tbh i had no idea what a "meta-aggregator" was but after @_nonlinear won today's auction for attention @qrcoindotfun, i took a few minutes to learn.

3 things to understand: aggregators, meta-aggregators, and spanDEX.

AGGREGATORS: monitor liquidity across multiple DEXes to find the best prices for swapping, reduce slippage, and facilitate more complex swaps.

META-AGGREGATORS: monitor across multiple aggregators to offer similar benefits but one level higher, removing centralized risks of a single aggregator being down or broken or just worse compared to another aggregator.

(kinda wanna build a meta-meta-aggregator now)

spanDEX: is a fully customizable, developer-friendly, and open-source meta aggregator library. That means developers can inspect and contribute to the codebase, decide which aggregators to include, configure settings, and tailor the functionality to their specific use case.

wait, this is kinda like a meta-meta-aggregator actually

holy meta-aggregation!

anyway, if you're curious to learn more, check out their website or ping @_nonlinear with any questions (hopefully he is ok with this, i did not ask in advance).

happy meta-aggregating to all.

deSPXA is live on spanDEX

whether you buy, sell, hold, borrow, or lend you can now use spanDEX to get the fastest, best priced swaps on deSPXA

[Centrifuge @centrifuge]

S&P 500. Now built for DeFi.

deSPXA is live on @base.
Designed for open onchain markets.

→ trade it
→ borrow against it
→ short it
→ deploy it in strategies

Built by @centrifuge, deSPXA brings tokenized exposure to the S&P 500 via the @JHIAdvisors S&P 500 Index Fund, under license from @SPDJIndices.

[Jonny Mack @_nonlinear]

deSPXA is now live on @base and already being routed by @spanDEXsh

balancing the costs of regulatory compliance w/ the benefits of being onchain (permissionless, composable capital markets) is a Really Hard Problem that no one has solved at scale yet

the @centrifuge approach of “kyc on primary, permissionless on secondary��� feels right bc its maximally interoperable on day 1

the Fabric DEX Aggregator is now live on @arbitrum

whether you’re swapping between majors, memes, or stables you can now get extremely low latency, high accuracy swaps by routing @withfabricxyz

withfabric dot xyz

[Jonny Mack @_nonlinear]

aggregators compare DEXs to find the best price

meta-aggregators compare *aggregators*

1min on why 1 layer of aggregation isn't enough:

[Jonny Mack @_nonlinear]

the @withfabricxyz aggregator has started winning its first trades

our strong belief is that every aggregator in the spanDEX lib must earn the right to execute based on the merits of their performance, on a *per swap* basis

big things have small beginnings
