# Chainstack updates: July 22, 2026

> Chainstack Sui gRPC endpoints now support gRPC-Web, so the official Sui TypeScript SDK works against Chainstack nodes over HTTPS on mainnet and testnet.

**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](/docs/sui-tooling#grpc-from-code) for the SDK setup, [Sui gRPC endpoint](/docs/sui-grpc-endpoint), and [migrating from JSON-RPC to gRPC](/docs/sui-migrate-json-rpc-to-grpc).
