Avalanche: chain ID, RPC URLs and explorers

The official Avalanche RPC URL for the C-Chain is https://api.avax.network/ext/bc/C/rpc, and it returned chain ID 43114 when we tested it today. AVAX trades at $7.98 on CoinGecko at this check.

Avalanche C-Chain RPC URLs Tested Today

Two Avalanche C-Chain RPC URLs passed today's test, each returning 0xa86a, which is 43114 in decimal, to an eth_chainId call on November 8, 2026.

https://api.avax.network/ext/bc/C/rpc: the public endpoint in Avalanche's Primary Network docs.
https://avalanche-c-chain-rpc.publicnode.com: a free endpoint from PublicNode, also listed on chainid.network.²

The /ext/bc/C/rpc ending matters: it points at the C-Chain, while the P-Chain has its own endpoints, which PublicNode lists separately. For testing, the Fuji C-Chain uses https://api.avax-test.network/ext/bc/C/rpc and chain ID 43113.

Adding Avalanche C-Chain to a Wallet

Adding Avalanche C-Chain to a wallet takes five values: the network name Avalanche C-Chain, chain ID 43114, currency symbol AVAX, the RPC URL above and an explorer URL. chainid.network, the registry most EVM wallets read, lists the same chain ID and RPC as Avalanche's docs.³

Because the C-Chain runs the EVM, an Avalanche address looks like an Ethereum address, starting with 0x. The Ethereum chain page has the matching settings for mainnet Ethereum, so the two are easy to compare side by side.

C-Chain vs P-Chain vs X-Chain

The C-Chain, P-Chain and X-Chain are the three blockchains of Avalanche's Primary Network, and each has one job. Avalanche's docs describe them this way:

C-Chain (Contract Chain): runs the Ethereum Virtual Machine and Solidity contracts. Wallets, apps, USDT and USDC live here.
P-Chain (Platform Chain): handles validators and Avalanche L1 operations. Staking happens here, with at least 2,000 AVAX to run a validator.
X-Chain (Exchange Chain): handles Avalanche Native Tokens.

Only the C-Chain has an EVM chain ID, so an EVM wallet set to 43114 sees the C-Chain and nothing else. When an exchange says it supports Avalanche, check which of the three it means. Settings for other EVM networks sit in the chain index.

Avalanche Explorers for the C-Chain

Avalanche explorers for the C-Chain include the Avalanche Explorer that the docs link at explorer.avax.network/c-chain and Snowtrace at snowtrace.io. Tether and Circle both link their Avalanche contracts on Snowtrace, and chainid.network lists Snowtrace, Snowscan and Avascan.⁴

USDT and USDC Contracts on Avalanche

The USDT and USDC contracts on Avalanche are on the C-Chain. Tether lists USDT at 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7 on its supported protocols page, and Circle lists USDC at 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E.⁶

We read each contract's symbol over the public RPC today as a second check: the first returned USDt and the second USDC. Every chain's list sits on the USDT contract address page and the USDC contract address page.

How Avalanche Reaches Finality

Avalanche reaches finality through Snowman Consensus, which its docs say gives sub-second, irreversible finality. A node asks a small random group of validators which transaction they prefer, repeats the poll, and settles once a large enough majority keeps agreeing.⁷

AVAX has a cap of 720 million coins, 360 million were minted at genesis, and the fees paid on the network are burned.⁸ Ava Labs set the mainnet launch for September 21, 2020, The Block reported, and block 1 of the C-Chain is stamped two days later, September 23, 2020.

Questions People Ask About Avalanche: chain ID, RPC URLs and explorers

These are the questions people ask next about Avalanche: chain ID, RPC URLs and explorers.

What is the Avalanche C-Chain RPC URL?

The Avalanche C-Chain RPC URL is https://api.avax.network/ext/bc/C/rpc, published in Avalanche's docs. It returned chain ID 43114 in our test today. PublicNode's https://avalanche-c-chain-rpc.publicnode.com is a free alternative that also passed.

What is the AVAX chain ID?

The AVAX chain ID most wallets mean is 43114, the chain ID of the Avalanche C-Chain, which is 0xa86a in hex. The Fuji testnet C-Chain uses 43113. The P-Chain and X-Chain do not use EVM chain IDs.

Is Avalanche an EVM chain?

Avalanche is an EVM chain on its C-Chain, which runs the Ethereum Virtual Machine and accepts Ethereum tools and 0x addresses. Its other two Primary Network chains, the P-Chain for validators and the X-Chain for native assets, are not EVM chains.

Which network should I pick to send USDT on Avalanche?

To send USDT on Avalanche, pick the Avalanche C-Chain, because Tether's USDT contract 0x9702230a8ea53601f5cd2dc00fdbc13d4df4a8c7 lives there. Confirm the receiver supports the C-Chain first. The wrong network guide explains what happens when the networks do not match.
