BTTC (BitTorrent Chain)

BitTorrent Chain (BTTC) is the primary EVM-compatible scaling solution and cross-chain bridge for the TRON ecosystem, enabling seamless asset transfers between TRON, Ethereum, and BNB Chain. By leveraging Proof-of-Stake consensus and supporting standard Solidity developer tooling, BTTC provides the high-performance infrastructure needed for interoperable decentralized applications.

Only use the official bridge and documentation at bt.io. Cross-chain bridges are a high-value target for phishing campaigns — verify every URL before approving any transaction.

What BTTC Does

BTTC serves two roles simultaneously:

1. Cross-chain bridge — lock assets on a source chain (TRON, Ethereum, or BNB Chain), receive wrapped equivalents on the destination chain, and unlock originals on redemption
2. EVM-compatible execution layer — deploy and run smart contracts using the same Solidity toolchain as Ethereum (Hardhat, Foundry, MetaMask, ethers.js)

This dual function means BTTC is both the infrastructure for moving value between chains and an independent smart contract platform in its own right.

Supported Networks

Network	Bridge support	Notes
TRON	Yes	TRX and USDT TRC-20 bridge to BTTC
Ethereum	Yes	ERC-20 tokens bridge to BTTC
BNB Chain	Yes	BEP-20 tokens bridge to BTTC

Consensus and Security

BTTC uses Proof-of-Stake consensus. Validators stake BTT to participate in block production and earn staking rewards. The validator set secures both the chain and the cross-chain bridge checkpoints.

BTTC 2.0 Mainnet launched June 30, 2025, delivering scalability improvements and upgraded cross-chain infrastructure supporting higher-volume bridging.

BTT: The Gas Token

BTT is the native gas token on BTTC — required to pay transaction fees, just as ETH is used on Ethereum. BTT exists as a TRC-10 token on TRON and has equivalent representations on Ethereum and BNB Chain via the BTTC bridge.

For Developers

BTTC is EVM-compatible, which means:

• Deploy Solidity contracts with no code changes
• Connect MetaMask or any EIP-1193-compatible wallet by adding the BTTC network (RPC settings available at bt.io)
• Use Hardhat or Foundry exactly as on Ethereum
• Use block explorers compatible with standard EVM chains

The primary differences from Ethereum development are the gas token (BTT instead of ETH) and significantly lower fees.

For Users: Bridging Assets

Bridge risk

Cross-chain bridges have historically been targets of large exploits. Use only the official bridge at bt.io, verify contract addresses before approving transactions, and bridge only what you can afford to have at risk during the transfer window.

To bridge via BTTC:

1. Connect your wallet on the source chain (TRON, Ethereum, or BNB Chain)
2. Select the token and amount to transfer
3. Approve the lock transaction on the source chain
4. Receive wrapped tokens on BTTC or the destination chain

Transfer times vary — TRON to BTTC is typically fast; Ethereum finalizations may require a waiting period.

Network Scale

As of 2025, BTTC processed over $1.63 billion in cross-chain volume: TRON contributed the largest share ($917M), followed by Ethereum ($692M) and BNB Chain ($20M).
