Trade your shielded $ZEC for confidential USDC on Ethereum, without ever unshielding it. No bridge. No custodian. No wrapped ZEC. And the amount never shows up on chain. I connected @zama and @Zcash to make it work. Live on testnet 👇 What it is ZEC Desk is a small trading desk on Zama's FHEVM, on Ethereum Sepolia. On one side there's cUSDC, a dollar token whose balances are encrypted. On the other side there's shielded ZEC on Zcash testnet. You can trade either way. Built on Zama's model Zama's Confidential RFQ is already live on Ethereum mainnet, open to everyone: It runs confidential swaps with encrypted quotes, a sealed-bid pick on chain and a hidden floor. ZEC Desk takes that same model and extends it to native shielded ZEC. Zama's swap settles both legs on one chain, inside its own contract, so a Zcash leg can't plug into it directly. Here that leg lives on Zcash and settles minutes later with a proof, so the mechanics run in my own contract. It's a sketch of how native ZEC could sit next to Zama's swaps one day, with no wrapped token. How a trade works (buying ZEC) 👇 1️⃣ You lock cUSDC in the desk. The amount is encrypted. 2️⃣ Makers send encrypted quotes. Nobody sees anyone else's price, or the minimum you'll accept. 3️⃣ The contract picks the best one under FHE. 4️⃣ The winning maker sends shielded ZEC to your Zcash address, with the order's reference in the memo. 5️⃣ A zero-knowledge proof shows that payment happened, and the contract releases your cUSDC to the maker. If no proof arrives in time, your cUSDC comes back to you. Selling is the same in reverse: the maker locks cUSDC, you pay the ZEC, and the proof releases the cUSDC to you. Why these pieces Each piece does one job. Zcash keeps the payment private. Zama keeps the amounts encrypted and can still compute on them. Seam, the Zcash light client I built last month, connects the two: a contract checks every Zcash block header itself, and a RISC Zero proof shows a shielded payment reached the right receiver. The transaction, the note and the address never touch the EVM chain. The masked amount This was the hard part. Seam's proof used to write the paid amount in the clear, and ZEC amount × price gives away the dollar amount. So the amount is masked. The contract adds an encrypted one-time mask to the encrypted amount and reveals only the sum, which looks random to everyone else. The mask comes from a secret that the side receiving the ZEC hands to the payer. The proof checks that the payment was at least the sum minus the mask, and never states the amount. One-time pads are old, and Zama's RFQ uses one too. Using one to hand a value from FHE to a ZK proof is the part I haven't seen before. If you have, please send it my way. No vault, no signers Seam can read Zcash, but it can't take ZEC from anyone. So the design never needs someone to pay ZEC on someone else's behalf. Whoever pays, pays from their own wallet, and the escrow on the EVM side enforces the deal. The side that paid the ZEC can prove it itself, so nobody depends on the other side's goodwill. Seam does more than this Any EVM app that needs to know a shielded payment happened can use Seam: pay-with-ZEC checkouts, escrows, payouts, cross-chain orders. This desk is one example. Where it stands ↓ Testnet only, unaudited. On 12 November 2026 I ran a Buy end to end: ➡️ Settled with a proof: ➡️ One proof: 2 minutes on a rented RTX 4090, about $0.25 for the whole session ➡️ Gas per Buy on Sepolia: about 7.6M, in six transactions ➡️ A Sell also ran on Sepolia, up to the maker locking its cUSDC; it settles through the same proof step ➡️ Seam's light client is now deployed on Ethereum Sepolia too, next to Base Sepolia Where it can go ↓ → The desk only needs Zama's FHEVM and a cUSDC. Both already run on Polygon, where following Zcash costs a fraction of Ethereum mainnet. → Zama keeps adding chains. On any cheap EVM chain it reaches, the same desk can run, and if it comes to Base, Seam's relay already runs on Base Sepolia. → Zama's roadmap also goes beyond the EVM, to chains like Solana. Seam's verifier would need a port there. → On Ethereum mainnet, following Zcash header by header would cost over 2B gas a day, so batched header proofs are next for Seam. What it can't do yet - Settlement takes minutes, not seconds. Zcash confirmations set the pace, not the GPU. - Right now I'm the only maker, and a maker needs ZEC, cUSDC and a GPU. - Amounts are hidden, but EVM addresses are public.

TLDR of hyperliquid precompiles: EVM chains on HL (ie HyperEVM & Elysium) have precompiles (basically built in blockchain functions) that allow them to query prices of hypercore assets For example rn on HyperEVM, you can make a simple RPC call to the chain to get the mark price of $HYPE Elysium doesn't have this ability rn but will be able to in 4 weeks. The diff b/w elysium and hyperEVM is that elysium's prices will update every 70ms (hyperEVM is every 1s) And elysium will be able to query entire orderbook, while hyperEVM can only do bid/ask/mark A blockchain being able to query the full depth of a separate orderbook in real time is p cool. Maybe some volatility based univ4 hooks could use such information

今天有位朋友跟我说：每个币圈人，迟早都会经历至少一次被盗。 我：？？？姐们儿我快一年了，还真没被盗过啊… 他：那我给你列举一下，你到底有多少种可能被盗的方式。 然后上了一堂币圈安全课…… 你们有没有被盗过，在评论这里贴出来分享一下。 💀 币圈人的 13 种钱包消失术： 1️⃣ 连环签名陷阱 使用 Web3 钱包时，前面弹出一个正常签名，刚签完立刻又弹出一个恶意授权。 以为是同一笔操作，顺手点了确认，结果把资产操作权限交出去了。 2️⃣ 买到了假的比特币 在 EVM 网络上看到一个叫 BTC 的代币，以为自己抄到底了。 结果买到的是假币，甚至是只能买不能卖的貔貅盘。 3️⃣ 地址投毒 转账时直接从钱包历史记录里复制一个眼熟的地址。 前几位、后几位看着都挺熟悉，结果是攻击者伪造的相似地址。 钱直接转错人。 4️⃣ 助记词放错地方 助记词截图存在相册，上传云盘，或者直接存在电脑记事本。 某天设备中木马，助记词被窃取，整个钱包可能被搬空。 这个我已经好几个新手朋友犯过错，甚至有一个不小心直接把截图发给不认识的人了。然后过来问我怎么办🥹 5️⃣ AI 帮忙写代码，顺便把私钥公开了 图方便把私钥发给 AI，或者放进 AI 编程项目的配置文件。 结果操作失误，被一起提交到 GitHub 公共仓库。 AI 是真方便，私钥也是真没了… 6️⃣ 熟人突然找你借钱 朋友账号被盗，突然发消息说有个紧急项目，需要你帮忙转点 U。 聊了半天才发现，对面根本不是本人。 多在TG发生，还有可能伪装成想要和你合作让你转钱。 7️⃣ 看不懂签名，直接点确认 钱包弹出一大串英文、十六进制数据。 看不懂，但又急着参与活动。 反正先点确认再说。 结果签下了不该签的东西。 8️⃣ 空投没领到，钱包先空了 突然发现钱包里多了一个陌生代币，或者收到一个恭喜中奖的链接。 点进去领取，结果进入钓鱼网站，签了恶意授权。 9️⃣ 假客服比真客服还热情 账号遇到点小问题，马上有人主动私信，说自己是官方客服。 让你提供验证码，助记词，甚至要求共享屏幕。 问题没解决，资产先没了。 🔟 下载软件，顺便下载了木马 想装个插件，翻译工具，会议软件，随手从搜索结果下载。 结果电脑被远程控制，剪贴板里的转账地址甚至会被偷偷替换。 我刚入圈经历过一次，连夜把电脑重装了。 1️⃣1️⃣ 参加会议，钱包被盯上了 有人邀请你参加项目合作会议，让你安装指定软件或者远程协助工具。 一不小心给了不该给的权限，设备里的敏感信息就可能暴露。 这个也要小心骗子伪装成你的熟人或者同事。 1️⃣2️⃣ API 权限开太大 为了方便交易，把 API Key 接入陌生机器人。 权限没限制好，密钥又泄露，结果账户被进行非预期操作。 1️⃣3️⃣ 验证码也可能被劫持 以为有短信验证码就安全了。 结果遇到 SIM 卡换卡攻击，手机号被别人控制，账户验证环节也可能失守。 …… 听完我沉默了。 以前总觉得，不乱点链接，不告诉别人密码，应该就安全了。 现在发现，有时候不是黑客技术有多神奇，而是我们防范意识太弱了🥲 所以 Misa 最近也在认真补安全课。 💻 电脑端：OKX 安全助手 支持 Windows / macOS，可以扫描设备安全风险，针对木马、恶意远程控制、剪贴板篡改、私钥窃取等威胁提供监测和提醒。 👉 📱 手机端：OKX 安心盾 可以在 OKX App 中检查账户资格及设备安全状态，按指引设置 Passkey、大额提币保护、网页提币保护等安全措施。 符合条件的用户完成要求后，可以主动激活安心盾。特定的交易所账户被第三方接管损失，可能获得有条件的补偿，但并不覆盖 Web3 钱包及自己误操作的损失。 👉 当然，没有任何安全工具是万能的。 只有自身提高安全意识才可以，不然一大堆防盗门在提醒你，也抵不过你自己非要把钱转过去。 私钥不外传，签名不盲签，地址认真核对，永远是自己的第一道防线。 所以你还见过什么离谱的盗币套路？评论区帮 Misa 补充一下，让大家一起避坑！ 🖤 毕竟入圈可以交学费，但真没必要交给骗子。😭

Hex addresses are much easier to grind than Base56 Solana addresses and they are priced accordingly. A 4-char Sol address takes 11M tries where a 6-char EVM address takes 17M. You can get a 4-char Sol address or a 6-char EVM for just $10... or free for the first 1,010 launches.

NEAR Intents事件，目前看，主要原因是一处跨链存取款层的 bug导致。 官方的说法是： Omni 存取款基础设施和 NEAR Intents 智能合约交互时有 bug。合约侧漏洞已经补上。初步损失约 380 万美元，承诺全额赔付。 在分析原因之前，先来看看Intents到底是什么？ Intents，中文常说的是“意图”。意图交易跟普通dex交易不一样。 普通的dex交易中，每笔交易，都是精确交易，比如走哪条池子/分几跳/限定多少滑点/哪条链上执行，签名一笔具体交易。 Intents交易则不同，是声明式的，用户只说自己想要的，但对于路径本身完全是放开的。签名的是用户想要的那个条件。 比如说：“用 1 ETH 换至少 2,500USDC，30 分钟内有效。”签名的是这个条件，不是某一笔具体 swap，路径/对手方/是否拆单等都不进签名。 如果不做具体的签名，那么谁来实现最终用户要求的结果？ 这个时候，有个Solver的角色，可以是做市商/套利机器人/跨链桥等，他们相互竞价，谁能在约束条件内做得更好，谁来接手。 用户不关心路径，只关心成交条件有没有满足。结算仍落在链上合约里。 目前CoW Swap、UniswapX 都有这套模型，主要在单链。NEAR Intents 是搭在 NEAR 上的跨链版本：用户在一条链上表达意图，solver 到多链上找流动性。资产搬运靠 Omni 存取款层。 被提走资金的地址，文档里标为 HOT Bridge 在 BNB Chain 上的金库，不是 NEAR Intents 自己的主 EVM 金库。 这次被打的就是这条存取款通道和 Intents 合约之间的接口。 受影响的是这条跨链通道，不是 NEAR L1。具体情况是校验被绕过/额度被重复记，还是提款权限配错，还需要等官方复盘。
