什么是“Connext”？What is “Connext”?

Connext 是建立在以太坊L2网络的一个去中心化的互操作性协议。简单来说，使用Connext 能够在区块链和汇总之间建立快速、安全、信任最小化的桥接。Connext is a decentralized interoperability protocol built on Ethereum L2 network. In short, using Connext enables a fast, secure, trust-minimized bridge between blockchain and aggregation.

Connext如何运作？How does Connext work?

在使用 Connext的过程中，它迭代使用了 nxtp，这是一种用于通用跨链传输的轻量级协议。而 Nxtp我们可以理解为它是一个可以自动完成交易的简单合约。使用 Connext的主要特点：① 低成本（使用 Connext可以让用户体验到最便宜的跨链桥接基础设施）。② Connext是空间中最安全的协议且无需受信任的第三方（Connext已经完成了 Diligence对它的安全审计工作）。③ Connext 可以部署到任何类型的链或 L2 系统上并以相同的方式工作。In using Connext, it iteratively used nxtp, a lightweight protocol for general-purpose cross-chain transfers. And Nxtp can be understood as a simple contract that can automatically complete transactions. The main features of using Connext: ① Low cost (using Connext allows users to experience the cheapest cross-chain bridging infrastructure). ② Connext is the most secure protocol in the space and does not require a trusted third party (Connext has completed its security audit by Diligence). ③ Connext can be deployed to any type of chain or L2 system and work the same way.

根据 Connext官方的使用手册中，我们可以看到在 Connext交易中要经历三个阶段。① 路线拍卖（用户在选择跨链的路线后，路由器会进行相应并给出跨链所需要的时间和特定的价格）。② 准备阶段（在用户确认订单发起交易后，该交易将用户资金锁定在发送链上。同时路由器会将相同的交易提交到接收方链上并锁定相应数量的流动性）。③ Fulfill（当接收链检测到用户的跨链请求后，用户将在metamask中签署消息将其发给中继者以完成用户在接收方链上的交易）。According to Connext’s official user manual, we can see that there are three stages in the Connext transaction. ① Route auction (after the user chooses a cross-chain route, the router will respond accordingly and give the time and specific price required for the cross-chain). ② Preparation stage (after the user confirms the order to initiate the transaction, the transaction locks the user’s funds on the sender chain. At the same time, the router will submit the same transaction to the receiver chain and lock the corresponding amount of liquidity). ③ Fulfill (when the receiver chain detects the user’s cross-chain request, the user will sign the message in metamask and send it to the relayer to complete the user’s transaction on the receiver chain).

如何快速使用 Connext进行跨链？How to quickly use Connext for cross-chain?

对于如何使用 Connext进行跨链操作，本教程中将使用 “Polygon chain”和“Gnosis chain”进行示例。Connext的官方跨链网址是：https://bridge.connext.network/ For how to use Connext for cross-chain operations, “Polygon chain” and “Gnosis chain” will be used as examples in this tutorial. The official cross-chain URL of Connext is: https://bridge.connext.network/

如上面三张截图，当我们进入Connext的官方跨链网站时，我们可以看到界面非常的简洁。在页面中，我们可以看到每一条链的 gas fee；可供的跨链选择（Connext当前支持超过17个链的选择）。As shown in the three screenshots above, when we enter the official cross-chain website of Connext, we can see that the interface is very simple. On the page, we can see the gas fee for each chain; available cross-chain options (Connext currently supports more than 17 chain options).

如果我想从Polygon转移一些 USDT到 Gensis chain中，我们可以如下图所示选择出这两条链和币种。其次，我们可以在“Amount”中输入想要转移的币种数量。当这些步骤完成时，我们可以清晰的看到跨链所需的“手续费”和“预计接收时间”。If I want to transfer some USDT from Polygon to Gensis chain, we can select these two chains and coins as shown below. Second, we can enter the amount of currency we want to transfer in “Amount”. When these steps are completed, we can clearly see the “handling fee” and “estimated receiving time” required for cross-chain.

当然，我们可以点击 “Advanced options”。在这里我们可以实现将资金发送到另一个钱包地址，调用合约地址，添加通话数据，添加首选路由器和指定外部签名者的工作。Of course, we can click on “Advanced options”. Here we can implement the work of sending funds to another wallet address, calling the contract address, adding call data, adding a preferred router and specifying an external signer.

当准备工作完成时候，我们就可以点击 “Approve”，并在 Metamask中授予访问USDT的权限。Then点击 “Swap”并确认交易。When the preparations are complete, we can click “Approve” and grant access to USDT in Metamask. Then click “Swap” and confirm the transaction.

这里我们可以看到订单已经在进行中了。Here we can see that the order is already in progress.

当出现这个界面时，我们就可以签名并 赎回我们的资金了。点击 “Sign to Claim Funds”并在 Metamask中签名。When this screen appears, we can sign and claim our funds. Click on “Sign to Claim Funds” and sign in Metamask.

这时候我们就完成了此次的跨链操作，它在几分钟内实现。At this time, we have completed this cross-chain operation, which is realized in a few minutes.

最后，我们可以点击网页顶端的 “Transactions”，在这里可以看到每一笔交易记录和完成状态。如果订单出现问题不知道如何解决请及时进入Connext的官方discord联系（Discord链接在本文的最下方）。Finally, we can click on “Transactions” at the top of the page, where we can see the record and completion status of each transaction. If there is a problem with the order and you do not know how to solve it, please enter the official discord contact of Connext in time (the Discord link is at the bottom of this article).

Summary and personal thoughts

截止到目前，Connext已经完成了总桥接价值＄1.2B+，超过4500万美金的可用流动性，总交易笔数 650K+和 44个可用的实时路由器。在未来，Connext会桥接更多的链例如 Celo，Aurora，Harmony，Neon，ZkSync等等。同时，Connext也是我个人用的第一个跨链工具。它的速度真的非常的快并且手续费及其低廉。最重要的是，Connext团队的工作人员对待每一个客户都非常友好。这说明了该团队是真心希望可以将 Connext带到一个新的高度。因此，我强烈建议跨链工具首选“Connext”！In conclusion, Connext has completed a total bridge value of $1.2B+, more than $45 million in available liquidity, a total of 650K+ transactions and 44 available real-time routers. In the future, Connext will bridge more chains such as Celo, Aurora, Harmony, Neon, ZkSync and more. At the same time, Connext is also the first cross-chain tool I personally use. It’s really fast and the fees are extremely low. Most importantly, the staff of the Connext team treat every customer very friendly. This shows that the team really wants to take Connext to the next level. Therefore, I strongly recommend “Connext” for cross-chain tools!
