Brazil, Argentina, and Mexico are in the same region but operate under three fundamentally different regulatory frameworks, and those differences matter significantly if you're building cross-border.
Brazil has the most developed stack but just closed the cross-border stablecoin

- The junior dev job isn't dead. It's changed. @rccsousa, Developer at Subvisual, wrote about why AI is a pocket Senior, not a crutch. And why curiosity is the skill that matters most right now. Link in bio. #juniordevs #softwaredevelopment #ai
- Filecoin Station needed to reach users who'd never touched Web3. We redesigned it from the ground up: UX, UI, product design, and development. Full case study in the link in our bio. #web3 #productdesign #filecoin

- Replying to @subvisual and @ethuidev6/ Hardware wallet support, multi-chain environments, and a plugin API are already on the roadmap. ethui is open source and actively maintained. The foundation is solid, and the ecosystem is just getting started.
- Replying to @subvisual and @ethuidev5/ A Stack is your entire dev environment, saved. Network config, deployed contracts, accounts, ABI mappings. Flip between a mainnet fork, a fresh local Anvil instance, and a staging deployment in one click. Nothing resets. Nothing gets lost.
- Replying to @subvisual and @ethuidev4/ Deploy โ call โ inspect โ repeat. Every confirmation pop-up in that loop is a source of compounding friction. Fast Mode removes it entirely. Transactions auto-confirm. The full history stays visible. The speed difference is hard to overstate.
- Replying to @subvisual and @ethuidev3/ Testing how a protocol behaves with a whale wallet holding 10M tokens is impossible in production. In ethui, it's a two-second switch. Impersonation lets you sign as any address โ no private key, no testnet funding, no drama.
- Replying to @subvisual and @ethuidev2/ You deploy a contract. MetaMask has no idea it happened. ethui watches your filesystem in real time. It picks up your ABIs the moment Foundry writes them. Every function is decoded and callable from the UI. No Etherscan. No scripts. No address copy-pasting.
- 1/ Most wallets give you the same four functions and call it done. @ethuidev ships capabilities that don't exist anywhere else in the ecosystem. A thread on four of them. ๐งต
- Starbase started in Lisbon. We took it to Braga, to Coimbra, and on July 22 it comes back to where it all started. Space, food, no agenda. People sit down and get more done than they have in weeks. Link in bio to register. #starbase #web3 #buildinpublic
- Crypto can feel like a foreign language. @r3vl_xyz wanted to change that with a wallet designed from the ground up for people who had never touched crypto before. We designed it to feel like the banking app already on your phone. We wrote up how we designed the app on Dribbble
- Replying to @subvisual2/ The docs land alongside the bundle, in the same place the assistant is already reading. Everything that follows just works, no extra plumbing required. Full article in the link in bio. #llm #componentlibrary #devtools #ai
