web3_clientVersion

Nodes serving BNB Smart Chain, the BNB-fee network running PoSA consensus, are built on the geth code lineage, and web3_clientVersion reveals which build is answering you. The method returns a free-form version string that names the client software, its release tag, and the platform it was compiled for, much like Geth/v1.4.x.../linux-amd64/go.... Direct the request to https://bsc.therpc.io/YOUR_API_KEY on chain ID 56 and the node hands back its self-reported identity. That string helps confirm a node is on a current release, though the exact format shifts from one client distribution to another.

Use cases

• Read the build tag to decide whether a node is recent enough to enable behaviour that depends on a specific geth-family release.
• Stamp the version string into infrastructure diagnostic logs so you can later trace which node build handled a given request.

Parameters

This method takes no parameters. Pass an empty array [].

Errors & troubleshooting

Common pitfalls

• Managed RPC layers often substitute a branded or redacted string for the underlying build, so the response may not name the real geth-family version at all.
• Never gate production behaviour on parsing this string; probe for the actual method or capability you need instead, since the format is neither stable nor guaranteed honest.
