An EVM-compatible Avalanche C-Chain testnet for developers to rapidly and cheaply test smart contracts and dApps, featuring near-instant finality and faucet-supplied AVAX, Chain ID 43113.
Avalanche Fuji Testnet is Avalanche’s public EVM-compatible test network (native token: test AVAX) used to safely trial dApps, smart contracts, cross-chain bridges, and Subnets before mainnet deployment. It mirrors mainnet performance with fast blocks/finality (~2s), low fees (base fee typically ~25 gwei; simple transfers cost <0.001 AVAX), and protocol-level throughput demonstrated >4,500 TPS, though observed testnet activity is lower and bursty.
Fuji is unique for combining strict EVM equivalence with Avalanche consensus and native Subnet tooling, yielding near-instant confirmations (~2s) and higher throughput than many EVM testnets that run ~12s+ block times. Developers get faucet-funded low-cost testing, mainnet-parity RPC/Explorer support, and the ability to spin up and validate custom Subnets—capabilities and performance characteristics uncommon on competing testnets.
Avalanche Fuji Testnet uses AVAX as the gas token for transaction fees. You can obtain AVAX by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge AVAX to Avalanche Fuji Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Avalanche Fuji Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Avalanche Fuji Testnet you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add Avalanche Fuji Testnet to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send AVAX on Avalanche Fuji Testnet, ensure your wallet is connected to the Avalanche Fuji Testnet network, enter the recipient's address, specify the amount of AVAX to send, review the gas fee, and confirm the transaction in your wallet.
