Avalanche C-Chain chain ID answer

Avalanche C-Chain mainnet uses chain ID 43114 / 0xa86a, RPC URL https://api.avax.network/ext/bc/C/rpc, explorer https://snowscan.xyz, and AVAX as the gas token. Copy the fields below and verify them against the linked source docs before using them in a wallet, script, or app.

Chain ID: 43114 / 0xa86a

Copy Avalanche C-Chain config Open Avalanche C-Chain guide Explorer directory Gas token directory

Good fit when you need:

the Avalanche C-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.

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.

bash

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://api.avax.network/ext/bc/C/rpc

# Expected chain ID: 43114 / 0xa86a

Safety note

Avalanche distinguishes C-Chain chain ID from other Avalanche network identifiers. Confirm the RPC path includes /ext/bc/C/rpc before configuring EVM tooling.

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