Source snapshotJuly 4, 2026

Source evidence snapshot July 4, 2026. BNB Smart Chain mainnet uses chain ID 56 / 0x38, RPC URL https://bsc-dataseed.bnbchain.org, BscScan explorer, and BNB as the gas token. Verify BNB Chain docs and current dataseed availability before using the public endpoint.

BNB Smart Chain RPC status and chain ID answer

BNB Smart Chain mainnet uses chain ID 56 / 0x38, RPC URL https://bsc-dataseed.bnbchain.org, explorer https://bscscan.com, and BNB as the gas token. Use the latest source check and linked docs to verify the fields before adding the network to a wallet, script, or app.

Chain ID: 56 / 0x38
RPC URL: https://bsc-dataseed.bnbchain.org
Explorer: https://bscscan.com
Gas token: BNB

Config path: wallet_addEthereumChain JSON

Availability check:BNB public dataseed endpoints are shared infrastructure. Intermittent failures can be rate limits or endpoint availability, so production apps should use monitored provider access or their own infrastructure.

Copy BNB Smart Chain config Open source docs Explorer directory Gas token directory

Good fit when you need:

the BNB Smart Chain chain ID, RPC URL, explorer, and gas token in one place;
source documentation links beside the copied setup fields;
manual wallet config fields without connecting a wallet or choosing an RPC provider.

Before you paste these fields:

compare the chain ID against the source link on this page;
open the explorer once and confirm it matches the network you expect;
use the public RPC for setup checks, then choose monitored infrastructure for production traffic.

Verification record

Automated source snapshots and recorded probe evidence are tracked separately. The source snapshot timestamp is not a manual review date. This is not a live uptime, latency, or production reliability monitor. If a recorded public RPC probe fails, verify the source links and current endpoint availability before changing production configuration.

BNB Smart Chain wallet-add fields

Wallet directory sites often expose a connect button. Main.net keeps the same MetaMask and EIP-3085 setup fields as text so developers can compare them with official/source docs before calling wallet_addEthereumChain.

Monitoring evidence

These checks are review signals only. They are not uptime, latency, privacy, or production reliability claims. A source fetch failure or eth_chainId failure can mean a source page or public RPC endpoint was unavailable, changed, or rate-limited during a check. Re-open source links and test current RPC availability before relying on a public endpoint.

curl eth_chainId check

Minimal JSON-RPC identity check. This verifies the endpoint-reported chain ID only, not uptime or production suitability.

curl -s -X POST \
  -H 'content-type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}' \
  https://bsc-dataseed.bnbchain.org

# Expected chain ID: 56 / 0x38

Safety note

BNB Chain lists several public RPC endpoints. Public dataseed endpoints can be rate-limited or unavailable, so use monitored providers or dedicated infrastructure for production traffic.

Main.net is an independent reference site. It does not operate this chain, custody assets, execute transactions, or provide investment advice.
