Build on arc network

[Tsao Lin @brasilkk22]

I recently developed a decentralized perpetual contract dApp on the Arc testnet. It supports trading not only cryptocurrencies but also US stocks on-chain around the clock.

@mysucesstory Hey friend, the dApp you developed works really well—I just tried it out and it's great. You should give my perpetual contract dApp a try, too.👍

@Panchu2605 @arc Thanks. There are too few scammers and too many fools😂

[Panchu @Panchu2605]

everyone "bridging to @Arc mainnet" this week: you didn't bridge to anything.

you handed real USDC to one anonymous person and got back an IOU they can print out of thin air. i read all three contracts this morning. let me show you what's actually happening to your money.

the pitch flooding your timeline: deposit USDC on Base, receive eUSD on Arc mainnet, "your USDC stays locked, bridge back anytime." clean. safe-sounding. it isn't true, and i can prove every word of that in one function call.

the vault on Base, the bridge on Arc, the eUSD token, all three are unverified. no source published. one single wallet owns all three. and that wallet has a function literally named sweep(). i tested who can call it: everyone is rejected except the owner. when the owner calls it, the entire USDC reserve, about $490,000 right now, moves to any address they choose, in one transaction. "locked" is a word on a website. it is not a property of the code.

the eUSD in your wallet is backed by nothing you can verify. Arc mainnet isn't open and there's no real bridge from Base yet, so nothing onchain checks that a deposit even happened before eUSD gets minted. a keeper wallet prints it on trust, and it trades against real USDC in a uniswap v3 pool on Arc. that pool is the door the money leaves through.

YOU CAN'T BRIDGE OUT
want out? their own bridge contract returns exchangeOpen = false and isSolvent = false at this very moment. you can put money in. the "bridge back anytime" path is shut, and the owner holds a freezeBridge() switch.

and here's the part that should end the conversation. they take a 10% fee on this, raisable to 25% whenever they feel like it, and that money is not sitting in a treasury. it's being bridged straight out of the system. that fee wallet has already pushed over $200,000 of USDC out through a cross-chain relay this week, including a single $142,000 transfer this morning. the fees are leaving as fast as they come in.

none of these people have a name. the wallet that owns everything was funded by a sibling wallet with a matching vanity address, spun up hours before launch, with no identity attached to any of it.

no audit. no verified code. no multisig. no timelock. no team a single person can name, and their fees already being relayed off to other chains. the only thing between half a million dollars and one keypair is one anonymous stranger deciding not to sign.

this is not Arc. Arc mainnet is not open and there is no official bridge open yet. do not put USDC into this. if you already did, your eUSD is worth exactly what one anonymous wallet decides, for exactly as long as they decide it.

don't trust me, verify it. vault 0x01a29660520C693615A62382603a4cAC7ffD4A15 on Base, owner 0xacBadF5a2c7917759867534eF9772D6C9CE6e501. read it yourself before it reads your wallet

STAY SAFE 🙏

Some systems are held together by filing cabinets, approval chains, and the occasional misplaced vacuum cleaner.

Arc is built for the next one. The Economic OS for the internet.

Programmable money. Always-on settlement. Infrastructure for the agentic economy.

可能算是一个信息差吧，https://t.co/w7cFTPLC6D 支持国内个人身份证注册账号，接入到网站里，向全球用户收款美元。
具体见他们官方公众号 https://t.co/Rcb0MpPR2w
不过注意，他文章里入口放错了，会导致跟着步骤只能注册国内企业账户，需要自己手动打开浏览器，从 https://t.co/vvg9sRd0rP 首页进入注册，选择个人卖家才行。
再次注意，是 https://t.co/w7cFTPLC6D 不是 https://t.co/cfmNNw5Kug ，虽然你在 cn 注册后，有一些步骤也是在 com 完成的，但一开始注册必须在 cn 。
另外可以自豪说一下的是，这个事是我从2024年接触到 PayPal 中国上海总部工作人员后推动的，见了各级领导，在多个场合见缝插针的被安排跟更高级的领导聊这个事，最终促使他们决定做这个事。
在正式官宣之前，我跟他们内部测试了半年多。
在此之前，https://t.co/w7cFTPLC6D 虽然也支持个人卖家注册，但只有实体产品网站才会被审核通过，后来在2026年1月正式官宣，虚拟产品也可以接入了。
