An EVM-compatible testnet on the Internet Computer, Bitfinity Network Testnet delivers ultra-low fees and native Bitcoin integration for fast, secure, bridge-free DeFi and dApps.
Bitfinity Network Testnet is an EVM-compatible Bitcoin Layer 2 environment that uses BFT (valueless) as gas so developers can deploy and test Solidity smart contracts and cross-chain bridges safely. It targets Bitcoin-first use cases like DeFi, payments, and NFTs with native BTC interoperability (no custodial wrapping), using standard EVM tooling and a faucet for rapid iteration. For comparison, testnet performance targets are ~1s block speed, >1,000 TPS, and sub-cent average gas per simple transfer (activity fluctuates with test events).
Bitfinity is unique in combining native Bitcoin interoperability (contracts can send/receive BTC without wrapped assets via threshold signatures) with full EVM compatibility for MetaMask, Hardhat, and Foundry. Built for fast finality and low fees, it targets ~1–2s blocks, >1,000 TPS, and <$0.01 average gas on testnet—typically faster/cheaper than most L1s while retaining Bitcoin liquidity. This Bitcoin-first, EVM-native design reduces bridge risk and enables seamless cross-chain DeFi and payments experimentation.
Bitfinity Network Testnet uses BFT as the gas token for transaction fees. You can obtain BFT by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge BFT to Bitfinity Network Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Bitfinity Network Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Bitfinity Network 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 Bitfinity Network 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 BFT on Bitfinity Network Testnet, ensure your wallet is connected to the Bitfinity Network Testnet network, enter the recipient's address, specify the amount of BFT to send, review the gas fee, and confirm the transaction in your wallet.
