Money left on‑chain. Still yours.留在链上，仍属于你。

Most of these contracts are immutable. Nobody can close them or move the money, and the rightful owner can take it out at any time. People forget because the project shut down, the airdrop was never announced to them, the amount was small compared with gas, or the wallet was simply left alone. Most of these contracts have no deadline, but we cannot promise that for every one: we have not checked each contract for an owner-controlled recovery function. If you decide to claim, sooner is safer.

这些合约大多是不可修改的：没人能关掉它们或挪走里面的钱，主人随时可以取出。钱留着，是因为项目关了、空投当时没通知到、金额比 gas 还小、或者钱包就这么放着。多数合约没有期限，但我们不能对每一个都打包票：没有逐个检查它们有没有主人可用的回收函数。决定要领的话，早一点更稳妥。

1. Use the wallet that owns the address you looked up. Never type a seed phrase or private key into any site.
2. Open the contract link from the result card on etherscan.io, not from a search result or a message.
3. First use Read Contract to check the balance. Then use Write Contract with the values shown on the card.
4. Before you confirm in your wallet, check that it names the function shown on the card and the same contract. It must not ask for a token approval, unless the card itself lists an approval step: a few old refund contracts (for example The DAO and DigixDAO) take your tokens back in exchange for ETH, and there the approval names the refund contract shown on the card, for the amount shown.
5. If anything on screen differs from the card, stop.

1. 用拥有该地址的钱包操作。任何网站都不要输入助记词或私钥。
2. 从结果卡片里的链接打开 etherscan.io 上的合约，不要从搜索结果或别人发来的消息进入。
3. 先用 Read Contract 核对余额，再用 Write Contract，填卡片上给的值。
4. 在钱包里确认之前，看它写的函数名、合约地址是否与卡片一致。它不应要求代币授权，除非卡片本身列出了授权这一步：少数老的退款合约（例如 The DAO、DigixDAO）要收回你的代币再退 ETH，这时授权对象必须是卡片上写的退款合约，数量是卡片上写的数量。
5. 屏幕上有任何地方和卡片不一致，就停下。

A site that asks you to connect a wallet and sign a transaction looks exactly like a phishing site, and a bug in it would be a bug in your money. We chose to be boring: we show you the contract, the function and the values, and you make the call yourself from your own wallet on Etherscan. That takes a few minutes, and it means this site never touches your funds.

要求你连钱包、签交易的网站，看起来和钓鱼站一模一样；而且它出 bug，就是你的钱出 bug。我们选择朴素的做法：告诉你合约、函数和参数，由你自己在 Etherscan 上用自己的钱包发起。多花几分钟，换来的是本站永远碰不到你的钱。

Yes, up to 100 per batch. Use the Batch tab, paste addresses or drop a .txt or .csv file, and you get a table you can sort by amount, expand row by row, and export as CSV. The file is read on your device and the CSV is made in your browser: nothing is uploaded. Each address is looked up the same way as a single one: your browser requests one data file per address, and the requests in a batch are visible together. For more than 100 addresses, run several batches.

可以，一批最多 100 个。切换到「批量」，粘贴地址或拖入 .txt、.csv 文件，就得到一张按金额排序、可逐行展开、可导出 CSV 的表。文件在你的设备上读取，CSV 也在浏览器里生成：不上传任何东西。每个地址的查法和单个查询一样：浏览器为每个地址请求一个数据文件，同一批的请求会被一起看到。超过 100 个，请分几批查。

Most of it is our own scan. Part of it comes from the open-source Forgotten ETH index (forgotteneth.com), which lists old contracts that still owe users money. We treat that index as a list of leads only: we read every balance again on our own Ethereum node and simulate each withdrawal from the owner’s address, and we publish only what that simulation pays out. Unlost is not affiliated with Forgotten ETH.

大部分来自我们自己的扫描。一部分来自开源的 Forgotten ETH 索引（forgotteneth.com），它列出了仍欠用户钱的老合约。我们只把这个索引当作线索：每条余额都在自己的以太坊节点上重新读取，每个取款调用都以主人的地址模拟，只公开模拟里真的能转出来的钱。Unlost 与 Forgotten ETH 没有关联。

Every result shows the block at which it was verified, with its date. Some kinds are re-checked at a recent block (26,253,876, 2026-10-23 07:37 UTC); others show the block of their last verification, which can be older. A balance can change after that: if the Read Contract value differs from the card, trust Etherscan.

每条结果都写明核验区块和日期。部分类别在较新的区块（26,253,876，2026-10-23 07:37 UTC）重新核对过；其他类别显示各自最后一次核验的区块，可能更早。余额之后可能会变：Read Contract 读到的值和卡片不同时，以 Etherscan 为准。

No. The lookup runs in your browser, which does not send the address itself. The server sees a request for one of 8,192 data files; the file name narrows the possible listed addresses to the roughly 40 in that file, and candidate lists or other information may narrow them further. We publish no plaintext address list. The page has no analytics code. Like any website, it is served by a hosting provider (Cloudflare) that handles ordinary web requests.

不会。查询在你的浏览器里完成，浏览器不直接发送地址本身。服务器看到的是「请求了 8,192 个数据文件中的某一个」；文件名会把已收录地址的候选范围缩小到这个文件里的大约 40 个，结合候选清单或其他信息，还可能进一步识别。我们不发布明文地址清单。页面里没有任何统计代码。和所有网站一样，它由托管服务商（Cloudflare）提供，后者会处理普通的网页请求。

No. Looking up is free, and claiming yourself earns us nothing. You pay only the Ethereum network gas for your own transaction. If a gas fee would be larger than the balance, it is probably not worth claiming right now.

不用。查询免费；自己领取，我们既不收费也不抽成。你只付自己那笔交易的以太坊网络 gas。如果 gas 比余额还高，现在大概不值得领。

No. Unlost is an independent project. It is not affiliated with, endorsed by or acting for any protocol or company named on this site. We only read their public contracts.

没有。Unlost 是独立项目，与本站提到的任何协议或公司都没有关联，也不代表它们。我们只读取它们的公开合约。

No. It only means we found nothing in the contracts listed under “What we cover”, at the time of our last check. Other chains, other contracts, and balances below $1 are outside this site.

不是。只说明我们在「覆盖范围」所列的合约里、最后一次核对时没查到。其他链、其他合约、低于 $1 的余额，都不在本站范围内。
