X Layer is live on Chainstack Global Nodes 🛠️

The OP Stack L2 from the @okx team.
Until now it ran on Dedicated Nodes only. Now there is a shared, geo-balanced option too:

→ Mainnet and Testnet
→ Archive data included
→ debug_* and trace_* on paid plans
→ Chain ID 196, 1-second blocks

Start building on @XLayerOfficial ⤵️

Your swap can be profitable for someone else before it even executes 🥪

Whether you're exposed depends on the chain:

→ @ethereum, @BNBCHAIN: public mempool, searchers can see your tx
→ @base, @arbitrum, @arc, @RobinhoodCrypto: no public mempool, different problem

Chainstack has an add-on for each 🧵

[Chainstack 💙🛠️ @ChainstackHQ]

Neither replaces your contract checks. Private routing doesn't fix a loose slippage setting.

Before you ship:

→ Set amountOutMinimum and a deadline on every swap
→ Check that the Add-ons tab shows Active on the node you send through
→ A node without the add-on uses the standard route

The rest:

→ Scans stop at 60 s or the memory limit with error -32012 instead of hanging
→ A scan is cancelled when your client disconnects
→ Shred feed gaps cut to about a third, e.g. Frankfurt 1: 16.65% to 5.36%
→ getMultipleAccounts fetches in a single batch

This week @awscloud launched @ethereum and @solana snapshots ⚡

But when self-hosting, there are more protocols to support, plus deployment, failover, and monitoring.

Chainstack Self-Hosted brings together everything needed for your nodes to work flawlessly.

On AWS, too 👀

Web3 set out to rebuild the internet. Its technology is now reshaping the financial system it once promised to replace.

One mainnet run: 1,999 unique payments printed, 86,333 repeats filtered.

In our own measurement, the edge over a WebSocket subscription was tens of milliseconds. It's a protocol demo, not production infra.

Querying a server tells you what that server has seen.

xrplwatch listens to the XRP Ledger (@XRPLF) peer network instead, so you see transactions as they're relayed, before a ledger includes them ⚡

[Chainstack 💙🛠️ @ChainstackHQ]

Run it:

→ `uv run python xrpl_feed.py --watch OfferCreate,Payment`
→ One JSON transaction per line
→ `_heard_from` and `_heard_at` added to each one
