net_version on Avalanche
Returns the network ID as a decimal string. Largely superseded by eth_chainId but still queried by older tooling.
The legacy network id as a decimal string; for most chains it equals the chain id, but not always. Kept for old tooling — new code should read eth_chainId instead.

Chain ID 43114 (0xa86a) — the Avalanche C-Chain. The X-Chain and P-Chain are not EVM and don't answer JSON-RPC; subnets each have their own chain ID.

net_version on Avalanche — FAQ
How do I call net_version on Avalanche?
POST a JSON-RPC 2.0 request with "method": "net_version" to NodeFlare's Avalanche endpoint at https://rpc.nodeflare.app/avax/public. No API key is required for the public endpoint.
What does net_version cost on the free tier?
net_version is weighted at 1 compute unit per call. The free tier includes 3,000,000 CU/month, so that is roughly 3,000,000 net_version calls per month — no credit card.
Is net_version available on the public Avalanche endpoint?
Yes. net_version works on the public Avalanche endpoint (https://rpc.nodeflare.app/avax/public) with no API key, limited to 1 request per 10 seconds per IP. A free key adds an authenticated endpoint with higher limits.
Anything Avalanche-specific to know when using net_version?
Chain ID 43114 (0xa86a) — the Avalanche C-Chain. The X-Chain and P-Chain are not EVM and don't answer JSON-RPC; subnets each have their own chain ID.
