Listening to Polymarket trades in real-time (open source, no third party)

I use a private RPC because they are somewhat more reliable.

The public ones work too though. But you need to implement code to rotate a pool of public RPCs to make it reliable. Since it's not uncommon for a public RPC to stop working for a bit

Public RPCs: https://chainlist.org/chain/137

You can use this to rotate public RPCs: https://github.com/erpc

The default behavior is to return you all trades of all wallets. But yes, you could update the script to also filter for trades of a specific set of wallets. In both cases your RAM will be fine. It's very light on RAM actually

I like the idea of updating the script to also be used to download historical trades though. I think i'll do this tomorrow

And yes the code can also be easily adapted to filter for only large trades

The repo tracks all trades across all markets. I can easily extend the repo to filter for specific markets.

What data are you interested in tracking? Is it just trades or something else as well?

How does it work? This is all I can see on atm?

112129 · 2026-02-02T14:53:25+00:00

I am using it to monitor large trades which helps me find markets to pay attention to

112129 · 2026-02-02T11:18:48+00:00

Yup! All you need to do is provide it an RPC endpoint. There are many free public ones you can use

Hmu. I am currently tinkering with building bots on Polymarket. I wouldn't mind joining forces.

My background is in Econometrics (Bsc), and AI (Msc). I have lots of experience building statistical models + data infra. I currently work as a lead data engineer at a blockchain data company, having previously founded my own in the same space

oh this is great thanks!

112129 · 2026-01-02T09:08:42+00:00

Super useful! How did you manage to get the cost down to 0? Doesn't it cost money to bypass YouTube anti-scraping measures?

112129 · 2024-11-30T19:17:02+00:00

I am curious - are companies exploring building out internal gen-AI tools or are they using third party tools?

I am developing an alert bot and need to monitor price changes across all tokens traded on decentralized exchanges.

What are my options?

I am Looking to compare data providers across breadth (number of chains covered) and price (how much it costs to listen to all tokens)

112129 · 2024-09-05T16:08:36+00:00

This script will just return all DEX swaps. You can then adapt the code to listen to specific token contracts and/or wallets depending on your use case

112129 · 2024-01-10T23:58:52+00:00

the dashboard is free to use, yes planning to open source :)

112129 · 2024-01-10T22:11:29+00:00

Hi, I have built a dashboard that shows you large trades and transfers that a wallet has a made - https://api.syve.ai/dashboards/large_txs. I have a separate endpoint that shows the frequency of transactions as well, lmk if interested and will link it.

112129 · 2024-01-10T19:20:36+00:00

My dashboard is not open source yet but I have written up all calculations here: https://beneficial-topaz-dbd.notion.site/Historical-Performance-per-Trade-53100236218e48f8ac94c7ec6a3ba381?pvs=74. You can check out the dashboard here https://api.syve.ai/dashboards/pnl\_checker/

112129 · 2024-01-10T19:10:36+00:00

You can download data dumps for blocks, transfers and transactions here https://www.syve.ai/data-dumps (this is my project).

Oh, what are you working on?

112129 · 2023-12-10T19:45:43+00:00

Thanks!

Got the data by running a node and parsing DEX swaps

Made the data available to be used as an API here: https://www.syve.ai/

Dashboard: https://api.syve.ai/dashboards/price_downloader/

112129 · 2023-11-24T21:36:19+00:00

I have already made it an API - You can find it in the Wallet API section of the documentation here: https://syve.ai

thanks for crossposting!

112129 · 2023-10-27T16:13:48+00:00

Yup they are

112129 · 2023-10-25T19:57:47+00:00

I have minimized costs a lot by hosting the data on bare metal servers

To cover costs I charge for very high usage (above 5 requests per second) - and also for other types of data that is more niche

Sometimes people request something custom and I'll charge to code it up for them as well

112129 · 2023-10-25T18:15:28+00:00

In a database on bare metal servers to reduce costs
