如何在 Grok bot 中使用 WIDTH,给一个教程: nitter.gq/widthgrc/status/211543…
如何将 Dart MCP 接入 Grok Bot 实操指南 第一步:获取 DART API Key 前往 width.info 后台(需完成企业认证),生成你的专属 DART API Key 并保存好(类似:be37d559-xxxx-xxxx-xxxx-xxxxxxxxxxxx)。 第二步:配置 Grok Bot 的 MCP 环境 在 Grok Bot 的 MCP 配置界面(如 mcp_config.json 或后台插件中心),添加 DART 的 MCP Server 地址,并将你的 API Key 填入环境变量配置中。Bot模板:x.ai/bot/_m6U31qU8KCBfFp-OdQ… 第三步:初始化对话与授权(可参考上方截图) 启动 Grok Bot,发送指令:连接 DART。 Bot 会弹出密钥卡片,将第一步获取的 API Key 填入。 (安全提示:DART MCP 仅用于建立连接,不会将你的 Key 写入 AI 记忆或聊天记录中) 第四步:开始筛查测试 Bot 提示“DART 已连上,可以用了”后,直接发送测试指令: 👉 筛查钱包地址:[输入你要测试的钱包地址] (如果是多链,Bot 会追问或者你可以直接带上链名,如:筛查钱包地址:0x... ,链名:ethereum) 第五步:获取结构化报告 稍等几秒钟,Bot 会自动调用 DART 的接口,直接给你返回该地址的风险评分(0-100分)、命中规则、四档处置建议以及资金风险路径。 How to Integrate Dart MCP into Grok Bot: A Practical Guide Step 1: Get a DART API Key Go to the width.info backend (enterprise verification required), generate your dedicated DART API Key, and save it securely (it will look like: `be37d559-xxxx-xxxx-xxxx-xxxxxxxxxxxx`). Step 2: Configure the MCP Environment for Grok Bot In Grok Bot’s MCP configuration interface (such as `mcp_config.json` or the backend plugin center), add the DART MCP Server address and put your API Key into the environment variable configuration. Bot template: x.ai/bot/_m6U31qU8KCBfFp-OdQ… Step 3: Initialize the Conversation and Authorize (see the screenshot above for reference) Start Grok Bot and send the command: `Connect DART.` The Bot will show a key card. Enter the API Key you obtained in Step 1. (Security note: DART MCP is only used to establish the connection. It will not write your Key into AI memory or chat history.) Step 4: Start Screening Tests After the Bot prompts “DART is connected and ready to use,” send a test command directly: 👉 Screen wallet address: [enter the wallet address you want to test] (If it is multi-chain, the Bot will ask a follow-up question, or you can include the chain name directly, e.g.: Screen wallet address: 0x..., chain name: ethereum) Step 5: Get a Structured Report Wait a few seconds. The Bot will automatically call DART’s API and return the risk score for that address (0–100), triggered rules, four-tier handling recommendations, and fund risk paths.

刚刚还有朋友来问,Cobo 是不是要关门,神鱼@bitfish 这个声明很清晰,转发一下,以正视听。
时间过得挺快的,Cobo 个人钱包上线已经 9 年了。其实 2021 年起就停止了新注册,这 5 年一直在给老用户留时间,现在定在 12 月 1 日停服,11 月 30 日前转出不会产生管理费。 Cobo 其他业务一切照常,机构朋友有需要,欢迎来聊聊 Cobo 机构钱包

最近协助一个 Perp DEX 和某地区监管机构沟通了近两个月,@WidthGRC 也因此琢磨出了一套针对去中心化产品的合规方案。 核心不是把 CeFi 的合规框架硬搬到 DeFi,而是做好 Compliance Trail:链上行为有迹可循、风险可识别、资金流可解释,真正遇到监管问询时,有完整的证据链和沟通语言。 WIDTH 做了一套 Crypto Native Compliance 解决方案:保留去中心化的产品逻辑,同时做到链上风险可识别、资金流可解释、合规过程可留痕、监管沟通可同频。 Stay decentralized. Stay explainable. Stay compliant.
What happens when money becomes programmable and AI starts operating at its speed? We were pleased to support @sgfintech_ ’s “A Programmable Economy at the Speed of AI”, co-hosted with the Ethereum Ecosystem Fund (EEF), bringing together the FinTech community for a timely conversation on AI, blockchain and the future of programmable financial infrastructure. Our Co-Founder & CEO, Chionh Chye Kit , joined Liraz Siri and Douglas Gan for a panel discussion following @VitalikButerin ’s presentation, exploring questions around AI agents, stablecoins, security, privacy, digital identity and trust. As financial infrastructure becomes increasingly programmable, building security, privacy and trust into the system will be just as important as the technology itself. Thank you to Singapore FinTech Association, EEF, the speakers and everyone who joined us for the discussion and networking session. #WIDTH #SingaporeFinTech #ArtificialIntelligence #Blockchain #FinTech #Stablecoins #DigitalIdentity #Privacy #RegTech #FinancialInfrastructure #AI

当受制裁地址与去中心化协议发生交易时,WIDTH 能够及时识别风险,记录资金路径、风险标签和处置过程,并根据既定规则完成调查、升级和必要处置,形成完整的合规留痕。 虽然无法阻止所有链上交互,但不代表协议没有合规责任。关键是风险可识别、资金可追溯、过程有留痕、监管能解释。 这就是@WidthGRC 针对去中心化产品设计合规方案的核心。

小时候父母为了我们兄弟俩读书,从农村搬到镇上,从镇上搬到县城。16 岁那年,我一个人去了北京,一待就是 13 年。在那里工作、创业、结婚,太太也是北京人。不知不觉,北京就成了生活的一部分。 挺有意思的是,我在北京 13 年,认识的重庆老乡不超过 5 个。印象比较深的,一个是猿辅导的联合创始人,一个是二八推的创始人。可能我们重庆人还是喜欢南方的气候,都跑去深圳、上海搞互联网了。 29 岁,我从北京搬到新加坡。又是一个陌生的城市,认识新的朋友,适应新的环境和规则。今天,办公室 80% 的同事都是新加坡本地人,60% 的客户来自新加坡本土市场。回头看,好像一直在搬家,也一直在重新扎根。故乡当然永远是故乡,但一个人的根,也会随着生活慢慢长到不同的地方。 重庆是我长大的地方,北京是我成家立业的地方,新加坡是我现在生活、工作,也是孩子们成长的地方。它们并不冲突,也不需要非此即彼。 我希望家乡越来越好,也希望祖国越来越强大,亲戚朋友的生活越来越富足美好。走得越远,反而越容易想起小时候的人和事。很多东西,离开以后才知道,家乡的烙印早就留在自己身上了。 但既然我们选择在一个地方生活,就应该认真对待脚下的土地。能不能站住脚,能不能挺直腰板,核心还是看能不能理解这块新土壤的规则、融入这里的社会、建立自己的信用和关系,并尽力创造一点价值。 落叶归根很好,落地生根也很好。人不一定一辈子只能有一片土壤,自己要记得从哪里来,也需要选择适合自己的沃土扎根生长。 蛮喜欢深圳这句标语“来了就是深圳人,来了就是志愿者”,融入环境的身份才叫身份。

这个是我最近十年交学费最多的地方,试图创造创业者,无一例外都失败了。
.@sama on why the best founders never run out of ideas: "You can give a founder an idea and they can start a company. The problem is they need to come up with new ideas for a company basically every week. Crazy new ideas, big changes, all the time. We tried an experiment once at YC where we funded 20 teams of strong founders who didn't have ideas but were otherwise really good. They all failed. And what we learned is that the good founders are the people who have ideas all the time. There's an intelligence component to this, a creativity component, an ability to think independent thoughts. But whatever you want to call it, this particular kind of intelligence that leads to seeing problems in different ways and thinking of ideas that don't yet exist but should, you've got to have that in a founder."

很多人问我,为什么还在创业?今天在 NUS EMBA 35 班开学典礼上傅强老师给出了一个很好的答案:创业最根本的意义,就是去开始(to begin)。 保持好奇,保持热爱,永远有重新出发的勇气,这或许也是我们和 AI 最大的不同。 – at Singapore
