The BNB Smart Chain chain ID is 56 (0x38 in hex). BNB Smart Chain, usually called BSC or BNB Chain, is the EVM network of the BNB ecosystem. Gas is paid in BNB and tokens follow the BEP-20 standard. Below are the exact settings MetaMask asks for, public RPC endpoints we tested on October 27, 2026, and a one-click button to add the network.
BNB Smart Chain Network Details for MetaMask
| Field | Value |
|---|---|
| Network name | BNB Smart Chain |
| RPC URL | https://bsc-dataseed2.defibit.io |
| Chain ID | 56 |
| Currency symbol | BNB |
| Block explorer | https://bscscan.com |
Copy these values exactly. If the RPC URL returns a different chain ID than the one you enter, MetaMask stops with a chain ID mismatch warning: that usually means a typo or an RPC for another network.
BNB Smart Chain RPC URLs (Tested October 27, 2026)
| RPC endpoint | Returned chain ID | Response time |
|---|---|---|
https://bsc-dataseed2.defibit.io | 56 | 346 ms |
https://bsc-dataseed1.defibit.io | 56 | 354 ms |
https://bsc-dataseed1.bnbchain.org | 56 | 355 ms |
https://bsc-dataseed3.bnbchain.org | 56 | 360 ms |
https://bsc-dataseed4.bnbchain.org | 56 | 360 ms |
We sent eth_chainId and eth_blockNumber to each endpoint from Europe on October 27, 2026; the table lists only endpoints that answered with chain ID 56. The latest block was 130,107,595. Public endpoints are free and rate limited: for an app or a bot, use a paid provider or your own node.
How to Add BNB Smart Chain to MetaMask
- Click Add BNB Smart Chain to MetaMask above, or open MetaMask and go to Networks → Add a custom network.
- Enter the network name BNB Smart Chain, RPC URL
https://bsc-dataseed2.defibit.ioand chain ID 56. - Set the currency symbol to BNB and the block explorer to https://bscscan.com.
- Save and switch to the new network. Your 0x address is the same as on other EVM networks.
Tip: BEP-20 tokens on BSC use the same 0x address as your Ethereum account, but they are different assets: send them only to a wallet set to chain ID 56.
BSC Testnet Testnet
| Field | Value |
|---|---|
| Network name | BSC Testnet |
| RPC URL | https://data-seed-prebsc-1-s2.bnbchain.org:8545 |
| Chain ID | 97 (0x61) |
| Currency symbol | tBNB |
| Block explorer | https://testnet.bscscan.com |
Testnet tokens come from faucets and are worth nothing. Do not send real BNB to a wallet connected to BSC Testnet.
How to Get BNB on BNB Smart Chain
The widget at the top of this page is set to swap into BNB on BNB Smart Chain: pick the token you have on another network, enter your address and sign once. Routes, fees and timing are covered in our BNB Smart Chain bridge guide.
