👉 Learn all swap and liquidity functionality with code on Uniswap V3 with examples: bit.ly/3JkXYqL
------------------------------------------
Have you ever wanted to listen to swaps on all Uniswap V3 pools?
In this video we'll programmatically find the addresses of all pools on Uniswap V3, and then listen for swap on each of them.
We'll do this with ethersJS.

@@blockmancodes yeah, your video is great, but seem no update for some time now, will update?

[@jerrywang3225]

Thanks. First time to use graph api and look forward to more tutorials on that.

[@blockmancodes]

Nice! It's pretty helpful

[@NamVo-mf1ns]

Hey, I wonder is there any hard limit of Ethereum on the number of contract events that we listent on?

[@sumanyasahoo9533]

In which part did you talk about the alchemy as a provider? @blockmancodes

[@rostam_jabbaroff]

I was already starting to think that I'm stupid and couldn't figure out where to talk about this.

[@jessejacob8256]

can the graph api be used on other chains like base?

[@ShoterOTP]

What if I want to get pools from BSC or other chains? Are those all of the pools on ETH chain?

[@СТАКАН-о5х]

how to get more than 6000 pools?

[@ivoleitao2883]

Great work and great tutorial! Thank you so much. Would you please give a hint on how you could increase the number of pools? I had a go with passing an incrementing variable on the query but did not work. I'm completely stuck! 😅

[@unaiiglesias9901]

Thanks a lot!! And how will be to listen for new pools created for the first time?

[@blockmancodes]

I'll add that to my todo list

[@oliverli9630]

awesome!! but does The Graph always stay up to date?

[@blockmancodes]

I've seen cases where it's not. If you need up-to-the-second data, query the pool directly

How do we, Can we do a Emergency Withdraw on Uniswap V3 interacting with their contract on Etherscan? I know it’s possible on Pancake writing to their masterchef contract

[@blockmancodes]

You could continually check the price and make the withdrawal from external code. But I don't think it's built into v3

[@shivanshyadav6740]

How can I fetch token details like price, market cap, liquidity from v3 SDK?

[@blockmancodes]

For price, use quoter For market cap, do totalSupply * price For liquidity, it's more difficult, check liquidity per tick on the pool contract

We want to swap video PancakeSwap or create nodes for the same router without using SmartRouterV3

[@blockmancodes]

I think I have a pancake swap video already. What do you mean "create nodes for the same router without using SmartRouterV3"? Can you give an example?

[@rs.ravi_sharma]

Thanks, this content is very helpful And how can I listen swap events for more than 6000 pools.

Please, sir, my teacher, to do additional videos on Pancakeswap, how to control the slip in the barefoot, how did the prices take from Oracle, and how the gas was set. Please, you are the only light that changed my life

is this useful for PancakeSwap V3 ?

Haven't tried but its on my todo list

NIce video, can you do one on using graph traversal to find optimal arbitrage swap routes?

[@pan-galactic-gargleblaster]

Most of us don't even use algo's for routes, there's certainly no need to. It's much easier to take the assumption that for any given token, the numeraire of the pair (base token) will be one of only 6 tokens [WETH, WBTC, USDC, DAI, USDT, stETH]. So lets say I want to swap from PEPE to AAVE. There isn't going to be a PEPE-AAVE pool, however, with absolute certainty, there will be a PEPE-WETH and an AAVE-WETH, making the path [PEPE, WETH, AAVE]. 99% of the time that will be the most liquid path, and therefore have the least price impact, and thus the least slippage, and therefore the "optimal" path. If you want to be 100% sure, you can check for each of the 6 base numeraires and return the one with the last slippage as your "optimal" path. What you might actually be asking, is "What is the optimal path, when taking into account multiple markets?" The answer to that my friend, is to do the above^ but for each market, each side of the trade, and each numereraire token. Then organize the results in an array, and filter them from least to most slippage. Take the chunk of the path that returns more than the original swap and you have a multi market optimal route for arbitrage. If it doesnt return more than the original swap, then there is no arb

[@blockmancodes]

@@pan-galactic-gargleblaster how to have a frameset just add the element you want to swap or replace the pair so they can work. i don't know the code i only hunt 1-2$ i really want a framework because bots are very fast

[@pan-galactic-gargleblaster]

We learned that graph is too slow for MEV (Guessing that's the reason you're here). Ditch caching and db's entirely. Hold pools in ram where it takes a fraction of one ms to read. Even Redis will be 10x slower reads than just instantiating 10,000 pools as consts.

[@pan-galactic-gargleblaster]

also, you can use keccak hashed event topics to listen for swaps in the mempool. Any tx's that happen on the router, simulate, look for the hashed event topic "sync()" in it's logs, and then if it exists, decode the sync() logs and you have the reserves to update the individual pool you instantiated previously. Since you're doing this inside the mempool, you end up with the future state of the pool before it gets mined. lots of fun activities with that knowledge
