We rebuilt Solana RPC on Chainstack and shipped big upgrades for @solana builders:

→ getSupply: 2 to 300 RPS
→ getProgramAccounts p95: 25-60 s to under 2 s
→ Median getLatestBlockhash: ~17 ms to ~2 ms
→ and 4 more upgrades

We detected and contained the attack, and are now focused on hardening our systems. Our findings indicate it was part of a large-scale, AI-powered attack campaign reported in late October.

Full details and updates are in our incident report.

The security and reliability of our systems remain our top priorities, and we are taking further steps to strengthen our safeguards. Thank you for your continued trust.

900K+ x402 payments from 10K+ agents on Celo.

Agents don't sleep, and neither should their RPC. Glad to power the read and write layer for builders shipping on @Celo.

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 🧵

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

Both add-ons are available on Global Nodes on every plan, Developer included.

Check both in our marketplace ⤵️
