**第一阶段任务：使用多序列器 L2 网络完成银河任务（5月4日至6月30日）**

**完成所有任务后，用户可以领取专门用于多排序器回合的 OAT（链上成就令牌）徽章**

对于测试网，我们将使用以太坊的 Sepolia 测试网作为 L1（终于不用goerli天价水了~）

首先Sepolia链领水：

没切换的先切换到Sepolia 测试网

**网络：**

**RPC：**[**https://testnet-rollup-api.altlayer.io/**](https://testnet-rollup-api.altlayer.io/)

**chain ID：9997**

**Token Symbol：ETH**

Sepolia 水龙头：

然后添加altlayer测试网.

然后梳理一下银河任务:

**三个交互任务：**

**1.通过Rollup Bridge在 AltLayer 测试网中存入和提取 ERC-721 (MSNFT) 2.通过汇总桥在 AltLayer 测试网上存入和提取 ERC-20 (MSEQ) 3.通过rollup bridge在 AltLayer 测试网上存入和提取 Sepolia ETH**

三个社交媒体任务：

进入Discord验证拿到Alters角色

关注alt\_layer

最优交互方案：

1-先完成领水eth以及**ERC-20 (MSEQ)**

[https://testnet-faucet.altlayer.io/](https://testnet-faucet.altlayer.io/)

进入[**https://testnet-rollup-bridge.altlayer.io/**](https://testnet-rollup-bridge.altlayer.io/)

![](https://storage.googleapis.com/papyrus_images/2ae801be846ed30bb3c9b8dd4312ebb3026b6dc44cc4b7726a659c9999944f0f.png)

2-通过rollup bridge存入提取NFT

[https://testnet-mint.altlayer.io/mint](https://testnet-mint.altlayer.io/mint)

最多mint十个。

然后进入

[https://testnet-rollup-bridge.altlayer.io/](https://testnet-rollup-bridge.altlayer.io/)

这里需要打开小狐狸钱包，找到刚刚mint的那笔交易查看NFT编号。

最后，确认一下存入跟提取的三笔交易。
