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
- An RPC never needs your seed phrase or private key. Your wallet signs; the endpoint only relays. Anything asking for a seed phrase is a scam.
- An RPC does see what you send: your address and your transactions. Choose one whose operator says what it keeps. Ours keeps the transaction, the sending address, the time and the requesting IP, and says so.
- The chain ID for BNB Smart Chain is 56. If a wallet shows a different ID for the network you are editing, stop.
The values
| Network name | BNB Smart Chain |
| RPC URL | https://rpc.backrunshield.com (or any other endpoint you trust) |
| Chain ID | 56 |
| Currency symbol | BNB |
| Block explorer | https://bscscan.com |
MetaMask
- The quickest way: on our front page, press Add to wallet and approve the prompt. MetaMask adds the network with these values filled in.
- 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.
- Make the new RPC URL the default for BNB Smart Chain and save.
Rabby
- Open Settings and find Modify RPC URL (listed under custom RPC in recent versions).
- 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
- Send a small transaction you would make anyway.
- Open it on BscScan from your wallet's activity list and confirm it was mined.
- 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.
