Wrap is a web interface that allows users to convert Bitcoin (BTC) into cBTC tokens and back, facilitating cross‑chain liquidity. The platform provides real‑time estimates of bridge fees and the amount of cBTC that will be received, enabling transparent minting and unwrapping of assets. It is designed for users who need to move BTC onto compatible blockchains while retaining the original value.

Problem
Bitcoin holders cannot directly use their BTC on most DeFi platforms because native Bitcoin does not conform to ERC‑20 or other smart‑contract token standards. Existing bridging solutions often lack transparent fee information, making it difficult for users to estimate the cost of moving value onto DeFi chains.
Solution
Wrap offers a non‑custodial blockchain bridge that locks native BTC on its originating chain and mints a corresponding wrapped token, cBTC, on the target DeFi network. The interface displays an estimated bridge fee and the exact amount of cBTC the user will receive before confirming the transaction, providing clear cost visibility. By automating the lock‑and‑mint process, Wrap enables Bitcoin holders to access lending, trading, and yield‑earning protocols without manual token conversions. The bridge also supports the reverse operation, allowing users to unwrap cBTC back into native BTC at any time. All operations are executed through audited smart contracts, ensuring that the underlying BTC remains securely locked until the user initiates an unwrap.
Target Audience
Primary users are Bitcoin holders seeking to participate in DeFi applications, as well as DeFi platforms that require BTC‑derived liquidity for lending, trading, or collateral purposes.
