Alchemy's RPC endpoints now come with built-in MEV protection on supported chains. This feature helps prevent frontrunning, sandwich attacks, and other forms of transaction manipulation with no additional code changes or tooling required.
By default, most blockchain transactions are broadcast to the public mempool. This exposes them to MEV (Maximal Extractable Value) risks, where bots insert transactions to extract profit at the user’s expense.
MEV protection mitigates this risk by routing transactions through private infrastructure. This improves transaction privacy, protects ordering, and reduces block inclusion time.
Transactions sent through Alchemy’s MEV-protected RPC endpoints are:
- Routed through private mempools — not broadcast publicly.
- Hidden until block inclusion — keeping sensitive trade details private.
- Ordered fairly — processed in the original sequence without manipulation.
- Shielded from frontrunning and sandwiching — keeping transaction intent intact.
This protection is powered through trusted Order Flow Auction (OFA) partners like Merkle and Blink.
MEV protection is automatically enabled on:
No configuration changes are required. Just send transactions to the standard RPC endpoint.
✅ Automatically protects transactions from MEV
✅ Faster block inclusion through private routing
✅ No changes required in dApp logic
✅ Included at no additional cost
