Elysium brings 100ms blocks and trading at Hyperliquid's pace.
If your router is slower than 100ms, you sign a stale route for every trade.
On @Enter_Elysium Fynd solves 98% of routes in <5ms, long before the next block, making Fynd by far the fastest router on Elysium.

Prices go stale quickly on Arc's 500ms blocks if your router can't keep up.
Fynd now routes your trades < 10ms across ~85% of @arc’s DEX volume.
Give users the best and latest prices on large cirBTC / EURC swaps on Arc.

Fynd now gets you the best quote on @ShapeShift.
Trade stocks, memes and stables across chains.
Fynd by @PropellerSwap is now live on ShapeShift.
Swaps on Ethereum, Base, Arbitrum, BNB Chain, Polygon and Robinhood Chain can now route through Fynd, helping you find the best rate on every trade.

Paying gas just to be told “try again” is a terrible trading experience.
On Ethereum, about 2% of router swaps revert on slippage. About half of them traders retry the same swap within 100 blocks.
Simulating 2,525 failed swaps we found that Fynd InBlock, would have
saved 20% of reverting swaps on calm days, and 29% on volatile days.
That's ~$100k-$2M of user swaps that failed, even though the right AMM liquidity was there to fill them – if the route were not stale.

Excited to co-host this one with @Astralaneio and @brewlabshq_!
See you in Mumbai
Mumbai, we’re days away.
Devcon is coming to town, and before it all kicks off, there’s Sangam.
Together with our brilliant co-hosts @brewlabshq_ and @PropellerSwap , we’re bringing the builders, validators, searchers, MMs and researchers out of the Telegram groups and into one room.
Zero panels. Zero pitches. Just the best of both worlds, with Indian hospitality.

Fynd AMM is live on @BNBCHAIN
Every swap is a small auction between pools. A normal pool sets its fee in advance. Fynd AMM compares prices across pools already on BNB Chain and charges the right fee to beat it. The trader gets a better fill. LPs keep the rest.
You get a better price, and Fynd AMM LPs win more trade and maximise their return.
First pool: $BNCB/USDT : swap.fynd.xyz/pools
Referrals are now live on Fynd.
Invite friends to swap and provide liquidity with your own link, and get a leaderboard multiplier.
More details coming soon.

Fynd Pools are live on Robinhood, Base, BND and Ethereum.
Stop blind-bidding. LP into Fynd AMM Ekubo pools and outbid the competition:

The result: 2.7x the fees on the same pool design.
For example, the last 60 ETH/USDG trades Fynd AMM won on Robinhood.
A hypothetical 30bps fixed pool with the same liquidity would only have won half the trades and earned 63% less in fees.

If competition is strong, Fynd AMM quotes tighter.
If competition is weak, Fynd AMM charges higher fees.
Fynd AMM moves last.
While Fynd routes your trade, it checks the competing pools' bids and tells Fynd AMM how to price.
Fynd AMM then charges the highest fee that still wins the trade.

So far, AMMs and propAMMs price blindly. Setting a price before the trade.
As a result, blind-bid AMMs miss out on trades they could win and overpay on the trades they do win.

Replying to @binji_x @barnabemonnot
for the end user:
- they see far fewer reverts
- and get much closer to theoretically optimal price (we'll share some data backing this up in the coming days)
present state:
1. trader comes to an aggregator and requests a quote at block n
2. aggregator shows a quote based on state of liquidity at the END of block n
3. trader signs approval and locks in the route, and blocks have moved to block n+1
4. txn is now sent to mempool
5. txn gets included in block n+2 if we're lucky, liquidity has already moved somewhere, that route the user locked is now far from best price
6. txn is executed and user got a much worse price because the route was stale
post fynd inblock:
1 - 4 remains the same.
5. builder sees special fynd inblock txn, they run fynd (super fast router) DURING block building on state of block n+2 right before inclusion postion (ie. current block)
6. they replace the route if/when there is better route computed live
7. txn is now executed, and user gets price closer per realtime state
possible only because fynd can run trustlessly within builders and no one needs to worry about leaking state.
user swapping a billion dollars gets 2bps more. tradfi only theorised this but could never ship.
If you are a wallet or dApp, add Fynd In-Block Solving and upgrade your routes with real-time solving on every trade on Ethereum.
