Conheçam o Bacuri, o mascote candidato ao
@SuperteamBR! 🇧🇷⚡
Curioso, criativo e persistente, ele representa uma comunidade que acredita que ninguém constrói sozinho. Com seu bloco em mãos, Bacuri chegou para aprender, colaborar e construir o futuro da Web3 na Solana.

Às vezes tudo o que falta pra algo grande acontecer… é só se arriscar e trazer suas ideias à tona.

Nunca tivemos tanta oportunidades no ecossistema para quem esta começando principalmente algo como essa que o @SuperteamBR e o @blockchain_rio esta trazendo para terras brasilianas junto com a @UNICEF !

1️�� True multi-network support (in development) Switching between testnet and mainnet is now handled via configuration rather than code: ARC_NETWORK=testnet|mainnet Testnet remains the default until mainnet (Summer 2026) is fully ready—without breaking changes.

Arc DevKit is now at version v0.8.0

🚀 Arc DevKit v0.8.0 is now available on PyPI!

The SDK now supports multiple networks, cross-chain bridging, an agent economy, a native MCP server, and other new features. (Testing and release of the new version.)

🧵👇

[Jeielsantosdev @Jeielsantosdev]

Wherever Arc/Circle haven't published an address yet (CCTP, paymaster, ERC-8004/8183 registries), the SDK fails loudly instead of pretending it works.

[Jeielsantosdev @Jeielsantosdev]

6️⃣ Prepping for privacy + post-quantum

Real view-key encryption (ECIES, tested against wrong keys and tampering) for selective disclosure, plus a pluggable signer interface ready for the post-quantum signer Arc has announced for mainnet.

[Jeielsantosdev @Jeielsantosdev]

5️⃣ Its own MCP server

arcdevkit mcp serve

Exposes balance, fee quotes, tx debugging, and agent reputation straight to Claude Code (or any MCP client). Arc becomes a tool your AI already knows how to use — no glue code.

[Jeielsantosdev @Jeielsantosdev]

4️⃣The one I'm most excited about: the agentic economy (ERC-8004 + ERC-8183)

AI agents register on-chain, build reputation,and hire each other with USDC escrow:

arcdevkit agent job create 0xAgent 25 --spec "summarize this PDF"

Two agents negotiating a job, no human in the loop

[Jeielsantosdev @Jeielsantosdev]

3️⃣ Cross-chain bridge via CCTP

arcdevkit bridge send 0xDest 10 --dest-domain 0 --dest-chain-id 1

Circle's burn → attestation → mint flow, with daily-spend guardrails and automatic error recovery if something fails mid-transfer.

[Jeielsantosdev @Jeielsantosdev]

2️⃣ Fees the way Arc designed them

arcdevkit fees quote 0xDest 5.0

Gas quotes always in USDC (native or ERC-20), with paymaster detection and ERC-4337 helpers already built for the day Account Abstraction lands on Arc.

🚀 Arc DevKit keeps getting better!

New releases improve developer experience with cleaner APIs, better docs, bug fixes, and new tools for building on Arc with Circle & USDC.
