An EVM-compatible testnet for BitTorrent Chain, Donau enables low-cost, fast-finality cross-chain dApp testing between TRON, Ethereum, and BNB Chain using BTT.
BitTorrent Chain Donau is the public EVM-compatible testnet for BTTC—a cross-chain protocol linking TRON, Ethereum, and BNB Chain—with BTT as the gas token. Developers use Donau to test cross-chain token/NFT transfers, generalized messaging, and Solidity dApps end-to-end using free test BTT before mainnet deployment. For comparison, Donau targets fast blocks (~2–3s), testnet throughput in the hundreds to low-thousands TPS, and effectively zero average gas cost—significantly faster and cheaper than Ethereum L1 (~12s blocks, high fees), with activity that varies by campaigns and testing cycles.
Donau is unique in that it mirrors BTTC’s native cross-chain architecture at the protocol level, enabling seamless bridging among TRON, Ethereum, and BNB Chain while remaining fully EVM-compatible and using BTT for gas. It combines seconds-level block speed and very low fees (near-zero on testnet; typically sub-cent on mainnet) with live bridge contracts and asset mappings, so teams can validate interoperability, finality, and fee behavior before launch. Compared with generic EVM testnets or L2s, Donau focuses on multi-chain performance—fast blocks (~2–3s), high practical TPS for testing, and bursty but responsive activity—optimizing developer workflows for cross-chain dApps.
BitTorrent Chain Donau uses BTT as the gas token for transaction fees. You can obtain BTT by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge BTT to BitTorrent Chain Donau, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select BitTorrent Chain Donau as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
