چند هفته پیش، زتاچین اولین قراردادهای هوشمند Omnichain را راه‌اندازی کرد که می‌تواند به دارایی ها،داده‌ها و نقدینگی در هر زنجیره‌ای دسترسی داشته باشد و آن را مدیریت کند. این نقطه مرجع جدیدی برای ساخت dapp ها است و تأثیر عمیقی بر زنجیره های مهم غیر هوشمند مانند شبکه بتکوین می‌گذارد و لایه قرارداد هوشمند را برای آنها به ارمغان می‌آورد که قبلا هرگز امکان‌پذیر نبود. پس از یک هفته، بیش از ۳۵ هزار کاربر در تست نت کیف پول XDEFI را نصب کردند و اولین معامله BTC بومی (بدون توکن رپد) را با سایر دارایی های DeFi انجام دادند. در این پست به اهمیت این ارتقاء فناوری برای توسعه دهندگان و کاربران و چگونگی شروع تعامل با بیتکوین در شبکه آزمایش زتاچین می‌پردازیم.
A powerful feature of smart contracts is that they can hold any assets like a normal account and receive and spend those assets according to programmed logic. The problem with some important blockchains such as Bitcoin, Dogecoin, Monero, and others is that they do not have a level of general smart contract capability to support common, useful dApps such as AMM exchanges, collateralized borrowing/lending markets with pools, and more. Currently, you cannot involve BTC or DOGE (without wrapping) in arbitrary logic in a decentralized and permissionless manner. Accordingly, developers and users are unable to take advantage of liquidity on these chains. The ecosystems are largely untapped and disconnected from the rest of DeFi.
One trailblazing advancement made possible by Omnichain Smart Contracts and the new ZRC-20 standard is the ability for developers to deploy contracts on ZetaChain that control Bitcoin natively. In other words, ZetaChain gives Bitcoin smart contract capabilities. These smart contracts orchestrate not only Bitcoin, but also Bitcoin together with assets and data from other chains. So users can now trade and use Bitcoin with any assets in the DeFi world without wrapping, thereby avoiding the risk of bridge/vault hacks. We expect this feature to rapidly accelerate growth in DeFi. Learn more about the technicalities of how this works in ZetaChain here.
ZetaChain enables you to build DeFi apps leveraging native coins of non-smart chains. In addition to support for smart contract-managed external assets such as BTC, DOGE, and others, you only need one contract to access users on all chains. This means less code (and attack surface), stronger transaction atomicity, and one place to manage the state of your omnichain applications.
Users don’t have to worry about having the right gas assets, managing multiple wallets across networks, and dealing with clunky UIs with questionable trust models. They can use one wallet and interface to hold and move around real assets like BTC and DOGE where the assets immediately settle as if everything were on a single chain. Fees, gas costs, and slippage is reduced because users engage with one contract that manages multiple tokens. All real logic occurs on ZetaChain where fees are bundled in a single step.
Right now, users can experience native cross-chain value transfer (with no wrapping) on ZetaChain’s testnet. We partnered with XDEFI Wallet to support a seamless experience for BTC swaps with other DeFi assets. Follow these steps to try it now, and start earning ZETA Points today.
