UniTap is a Bitcoin DeFi platform built on the TAP Protocol, offering decentralized token swaps, cross-chain bridging, and wallet management. Users can securely store, transfer, and manage TAP, BRC-20, and Rune tokens via its browser extension wallet, and utilize the built-in swap feature for trustless token exchanges on Bitcoin L1. The platform connects different token standards through bridging, facilitating asset flow across ecosystems. Its core mechanism leverages TAP Protocol's 'promises' technology to enable efficient on-chain token operations on Bitcoin mainnet while maintaining decentralization and transparency.
