📢 ZetaChain MCP Server We’ve released a preview MCP server that connects directly to the ZetaChain CLI. What you can do with it: 🔍 Query ZetaChain data from within AI agents 🌉 Broadcast cross-chain transactions programmatically 🤖 Integrate ZetaChain into tools like Cursor or Claude for automated dev workflows ⚠️ Heads up: This is an early preview — things may change or break, but it’s already functional and ready for experimentation. 👉 Try it here: https://smithery.ai/server/@zeta-chain/cli 🎥 New to MCP or want context?

Big update to the ZetaChain CLI 🔥 You can now deposit assets and call universal contracts from Sui, Solana, and TON, all in one line from your terminal. Plus: support for TON balances 💎 and real-time tracking of cross-chain transactions 🔭 You’ve already been able to go cross-chain from Bitcoin and EVM chains. Now we’re unlocking "deposit" and "deposit-and-call" from Sui, Solana, TON ✅ Same experience calling universal apps, no matter the chain The CLI now also supports TON balances 💎 Run: zetachain query balances And get a unified view of your ZRC-20s, EVM tokens, SOL, SUI, BTC, and TON, all in one place. But here’s the really powerful part! Introducing cross-chain transaction tracking 🔭 zetachain query cctx It gives you real-time visibility into every stage of a cross-chain transaction: ⬆️ Outgoing tx ⬇️ Incoming tx 🔄 Any dependent txs 🔀 Even multi-hop flows Cross-chain transactions are rarely linear ⛓ Sometimes a single deposit triggers 3 downstream events. Sometimes it bounces across multiple chains and throws an error 💥 ZetaChain CLI recursively tracks it all. So you never lose sight of what happened and why. All of this is live today in the CLI 🔥 Try it out: npx zetachain@next Or install globally: npm install -g zetachain@next Includes support for Sui, Solana, TON, Bitcoin, and EVM chains ⚙️
