# On-chain model

vBTC operates on BNB Chain under the BEP-20 standard, leveraging blockchain advantages such as transparency, strong security, and compatibility with DeFi protocols. The on-chain model offers maximum autonomy to users and enables participation in advanced financial applications.

* **Minting and Redeeming directly on blockchain**: Following standard procedures, users can mint or redeem vBTC via smart contracts on BNB Chain. The process is transparent and trustless, requiring no third-party involvement. Users deposit supported assets - including BTCB, USDT, USDC, ETH, or BNB - and the protocol issues vBTC based on the fixed peg rate of 1 BTC = 10⁸ vBTC. When redeeming, vBTC is burned in exchange for BTCB, maintaining strict supply control.
* **Personal wallet integration**: vBTC on-chain supports connection with major wallets such as MetaMask, Coinbase Wallet, OKX Wallet, and WalletConnect. Users must switch their wallet network to BNB Chain to access full functionality. Once connected, they can manage vBTC directly, view balances, and perform actions such as minting, redeeming, or transferring tokens.
* **DeFi potential**: vBTC is designed for integration with DeFi applications such as lending, staking, or yield farming in future releases. This opens opportunities for users to optimize returns while taking advantage of BNB Chain’s low fees and fast transaction processing.
* **Security and stability**: vBTC’s smart contracts are written in Solidity, offering transparency and ease of auditing. All on-chain transactions are secured by the BNB Chain infrastructure, reducing manipulation risk and enhancing reliability.
