Tomás aka DeFiRoni has just become an Architect! Above all, it’s been a really fun journey. After a few months trying to find the best environment to build, I found Arc, and it’s been the best thing that’s happened to me this year so far. I’ve already left my mark with @Zentryxapp, a bridge using CCTP, and I keep learning, fixing mistakes pointed out by the community, and growing my knowledge. This is just the beginning of my journey as a builder. I’m even more focused on the future and on improving Arc every single day. I couldn’t go without giving a special thanks to @onnerB_, my Brazilian brother, who, despite our time zone difference, him in Brazil and me in Portugal, was always available for any question or doubt I had. He was clearly the most important person in helping me get here. Valeu irmão.🇧🇷🤝🇵🇹 A big thanks as well to @samconnerone, @bobbilee, and @silencexlm, the people who work every day to make sure everyone has the best tools available to build. Thank you, team! As for the Arc Community, expect more of the same, nothing has changed. The focus remains the same, and the willingness to help is still strong. The mutual support in this community is clearly the deciding factor. Excited for what’s ahead!

Para os meus amigos que fazem parte da comunidade Arc. Hoje consegui finalmente autorização para publicar na Arc House. Depois de ter entrado no grupo do Brazil, que acaba por ser a comunidade com a qual me sinto mais à vontade enquanto português, publiquei lá a minha introdução para que me possam conhecer melhor e compreender um pouco mais sobre o meu percurso. Nesse texto partilho não só a minha experiência no mundo crypto desde 2023, mas também todo o processo que tenho vivido dentro do ecossistema Arc. Desde os primeiros passos como utilizador, à transição para a vertente de builder, até ao desenvolvimento da Zentryx e aos desafios que tenho enfrentado ao longo do caminho. Achei que seria uma boa oportunidade para reunir um pouco da minha história, explicar como cheguei até aqui e dar algum contexto sobre aquilo que tenho vindo a construir nos últimos meses. Para quem tiver curiosidade em conhecer melhor o meu percurso 👇 community.arc.io/home/clubs/…

We’re up to 2,000 official Architects…. and counting! built different. architects.

Building prediction markets gets harder when the infrastructure underneath is fragmented. Arc is designed to give developers a more usable foundation: → Gas paid in stablecoins like USDC → Multi-currency market creation and settlement → Deterministic finality → Built to support compliance with auditability and opt-in privacy If you’re building prediction markets for real-world use cases, build on Arc.

Over the last few weeks I've been investigating a small number of bridge transfers that successfully burned USDC on the source chain but never completed the mint on the destination chain. One thing that became clear during the investigation is that the core CCTP flow appears to be working correctly. Burns are being processed, attestations are being generated, and cross chain messages are being produced as expected. The challenge is that not every failed transfer appears to have the same root cause. During the investigation I was able to reproduce some failure scenarios across multiple routes and chains, while other reported cases could not be reproduced consistently. Some situations appeared to be related to transaction fee conditions at the time of submission, while others resulted in completed burns with pending mints that required manual intervention. Over the past weeks I've reviewed transaction flows, attestation data, mint execution paths, fee calculations, RPC behaviour, and recovery mechanisms while testing transfers across Ethereum Sepolia, Base Sepolia, Arbitrum Sepolia, and Arc Testnet. While investigating user reports, I also built internal recovery tooling to better understand and recover transfers that became stuck after the burn stage. Although the root cause behind every edge case has not yet been fully identified, I didn't want users to be left without an option when a transfer fails to complete. Today I've deployed a Recovery tool directly into the Zentryx bridge. If a transfer successfully burns on the source chain but does not complete the mint on the destination chain, users can now paste their burn transaction hash and attempt recovery directly from the bridge interface. The investigation continues, but users now have a recovery path available instead of waiting for manual intervention. Test now and give me your feedback🙏 Use a burner wallet!

Além de desenvolver na Arc eu também gosto de testar aplicativos que a comunidade está construindo para ajudar no feedback pois eu sei o quanto isso é importante para nós que passa muito tempo nos bastidores desenvolvendo. Hoje eu quero mostrar pra vocês um dApp desenvolvido por um Architect na arc. O Sparrow é um projeto construído na Arc que contem swap USDC <->EURC, bridge nativo de USDC e uma futura camada de agentes de IA facilitadores para atividades DeFi. Hoje a infraestrutura já utiliza: - LI.FI para agregação de liquidez de swaps ( atualização prevista para às próximas semanas, uso dos próprios contratos Sparrow router) - Circle App Kit SDKs. - CCTP v2 para transferências crosschain nativas de USDC. - RainbowKit para conexão simplificada de wallets. O ponto mais interessante é o uso do CCTP. O USDC não é wrapped durante o bridge. Ele é burnado na chain de origem e mintado novamente na chain de destino. Sem fragmentação de liquidez.

Today was my day and the day for a few hundred other builders. I want to connect with those who have also become architects.🫡

@Arc 🤝 @goldskyio Goldsky is joining the Arc ecosystem with support from the Arc Builders Fund to offer critical data infrastructure for teams building on Arc. That means developers on Arc can build with faster, more reliable access to the real-time onchain data their applications depend on. → Real-time indexing and data streaming → Scalable access to onchain data → Capital and ecosystem support through Arc Arc backs the infrastructure builders need to move faster. community.arc.io/home/blogs/…

Hi everyone Please join us at 10 AM EST! youtube.com/watch?v=EvrzGSdX…

I did the same. I chose to use a photo of my face on Arc House while keeping my privacy on X. I made this decision because I see Arc House as something different, it’s a place where real people matter. There’s no need to hide, since it’s where we have the chance to connect with others in the same field, building in the same space, at Arc. Showing your face also signals trust and openness toward others, which only benefits everyone involved. Following @silencexlm quote: “I love Arc so much I doxed myself, so take my example and use real info on Arc House!”
