MCP Server. The Chainstack MCP server testnet faucet now advertises its supported networks to your agent and accepts common aliases (ethereum-sepolia → sepolia, solana-devnet → solana), so testnet fund requests land on the first try instead of failing on a wrong-network name.

Protocols. Sui gRPC endpoints now support gRPC-Web, so the official Sui TypeScript SDK (@mysten/sui) works against your Chainstack nodes over HTTPS on Mainnet and Testnet — including from the browser, with only your node URL. Native gRPC and JSON-RPC are unchanged. See Sui tooling for the SDK setup, Sui gRPC endpoint, and migrating from JSON-RPC to gRPC.

Starknet. Chainstack is upgrading Starknet nodes to Pathfinder v0.23.0 — a breaking change to JSON-RPC API version support: versions 0.6, 0.7, and 0.8 are removed, and the default / endpoint now serves version 0.9. Pin /rpc/v0_9 or /rpc/v0_10 before the upgrade reaches your node.

Protocols. Chainstack now supports Robinhood Chain — an Ethereum L2 (Arbitrum Orbit, Nitro client) for tokenized stocks and real-world assets. You can deploy Global Nodes and Dedicated Nodes for Robinhood Chain Mainnet and Testnet, in Full and Archive modes with debug and trace.

MCP Server. Migrating from Alchemy now reads your usage via the Alchemy CLI (alchemy usage summary) — the agent pulls your spend and compute-unit volume to estimate your Chainstack savings.
​
by Ake
Protocols. TRON gRPC now serves the protocol.WalletSolidity service for solidified (confirmed) data, alongside protocol.Wallet. Both run on the same :443 endpoint — select the one you need by the service (stub) in your generated client. Available on TRON mainnet and Nile testnet.
​
by Ake
Add-ons. Warp transactions and MEV protection are now Chainstack node add-ons rather than baked-in node toggles. You install and manage them per node from the node’s Add-ons tab.
​
by Ake
Add-ons. Higher concurrent stream limits for the Yellowstone gRPC Geyser plugin. The $49/month tier now includes 2 concurrent streams (up from 1) and the $149/month tier now includes 7 concurrent streams (up from 5).
​
by Ake
MCP Server. The Chainstack MCP server now migrates your project to Chainstack from another RPC provider — QuickNode, Alchemy, or any other — assessing your usage, estimating your savings, and repointing endpoints from inside your AI coding agent.
​
by Ake
MCP Server. Every Chainstack MCP server tool now publishes a typed outputSchema, so agents can consume structured results without guessing field names. List tools also emit structuredContent — an additive, non-breaking change.
​
by Ake
Protocols. Hyperliquid /nanoreth is now on testnet as well as mainnet. Both /evm (default, hl-node-compliant — system transactions stripped from block-shaped responses) and /nanoreth (system transactions included) paths exist by default on every Chainstack Hyperliquid node, mainnet and testnet. Append the path you need to your endpoint URL. See Hyperliquid node configuration for the per-method behavior matrix.
​
by Ake
MCP Server. The Chainstack MCP server now supports all three Google Antigravity 2.0 surfaces — Antigravity CLI, the desktop app, and the IDE — on the discovery page.
​
by Ake
Protocols. Flashblocks on Optimism is live on every Chainstack Optimism mainnet node. The Optimism sequencer streams Flashblocks every 250ms, and Chainstack Optimism nodes expose the preconfirmation state through standard JSON-RPC calls with the pending block tag. See Flashblocks on Optimism for the full guide, including the Optimism vs. Base differences and performance expectations.
​
by Ake
MCP Server. Chainstack MCP tools now advertise standard MCP annotations (readOnlyHint, destructiveHint, openWorldHint) so clients skip prompts on read-only calls and require approval on writes, and the server reports its real release version on the initialize handshake.
​
by Ake
Protocols. Hyperliquid /nanoreth is live on every Chainstack Hyperliquid mainnet node. Append /nanoreth to your endpoint URL to get system transactions included in eth_getBlockByNumber, eth_getBlockReceipts, and direct hash lookups. The default /evm path is unchanged — hl-node-compliant, system transactions stripped from block-shaped responses. See Hyperliquid node configuration for the per-method behavior matrix.
​
by Ake
MCP Server. The Pi coding agent can now install the Chainstack skill (skill-only — Pi rejects MCP servers by design), and the discovery page description now covers pricing and testnet funds.
​
by Ake
Console. The new Agents page is live in the Chainstack console — one place to plug Chainstack into Claude Code, Codex CLI/App, Gemini CLI, Cursor, or any other coding agent: migration prompt, docs, MCP server, and Chainstack skill.
​
by Ake
MCP Server. New tool: get_chainstack_pricing answers pricing questions grounded in live data — plan tiers, add-ons, and the full per-chain dedicated-node catalog. No API key required.
​
by Ake
MCP Server. New tool: request_testnet_funds tops up testnet addresses with gas across 12 EVM, Solana, and TON networks, directly from your agent.
​
by Ake
MCP Server. New tool: contact_chainstack lets you reach Chainstack’s sales or support team directly from your agent. No API key required; the agent confirms before sending.
​
by Ake
MCP Server. The Chainstack MCP server is live at mcp.chainstack.com — deploy and manage nodes, search docs, and check platform status from any AI coding agent, via skill install or MCP registration.

Protocols. Sui Testnet is now available on Chainstack. You can deploy Global Nodes for Sui Testnet with JSON-RPC and gRPC endpoint support. See also Sui tooling.
