How to add a custom RPC for BNB Smart Chain

Updated 23 September 2026

Your wallet sends every transaction through an RPC endpoint. Changing it decides who sees your transactions before they are mined — the public mempool, or builders directly. It takes about a minute.

Before you start

The values

Network nameBNB Smart Chain Mainnet
RPC URLhttps://rpc.backrunshield.com (or any other endpoint you trust)
Chain ID56
Currency symbolBNB
Block explorerhttps://bscscan.com

MetaMask

  1. The quickest way: on our front page, press Add to wallet and approve the prompt. MetaMask adds the network with these values filled in, and the page then checks that your wallet's requests reach us.
  2. By hand: open the network selector, choose Add a custom network (or edit BNB Smart Chain's RPC URLs if it is already listed), and enter the values above.
  3. Make the new RPC URL the default for BNB Smart Chain and save.

Rabby

  1. Open Settings and find Modify RPC URL (listed under custom RPC in recent versions).
  2. Pick BNB Chain, paste the RPC URL and save. Rabby checks that the endpoint answers for chain 56 before it accepts it.

Other wallets and bots

Any wallet, bot or script that takes a custom RPC works the same way: the URL, chain ID 56 and currency BNB. Menu names move between versions, so look for "networks", "custom network" or "RPC".

Check that it works

Before sending anything: on our front page, press Check my wallet. Your wallet makes one read that only our endpoint answers, and the page says whether it came back from us. Nothing is signed or sent. To confirm with a real transaction:

  1. Send a small transaction you would make anyway.
  2. Open it on BscScan from your wallet's activity list and confirm it was mined.
  3. For our endpoint, look up your address on the stats page: the transaction appears there, marked as included privately or broadcast.

Switching back

Edit the network again and restore the previous RPC URL, or pick the default endpoint from the wallet's list. Nothing about your account changes; only the route your next transaction takes.
