Hyperweb

Hyperweb is a TypeScript development stack for Cosmos and the interchain ecosystem, formerly Cosmology, and also runs a chain whose contracts are written in TypeScript. Its tools cover signing, wallet connection, code generation and a local testnet, and the contract layer lets developers write in a language familiar from the Ethereum ecosystem and execute across chains. The pain point is that Cosmos multi-chain development means switching between languages and toolchains, raising the barrier for JavaScript developers.

Between March and May 2026 the repositories still received commits covering code generation, a wallet connection kit, a local testnet and a chain registry. A July 2025 blog post announced a shift toward a general backend platform and agents, with Cosmos tooling no longer the main line, and mainnet launch of the contract chain remains unconfirmed.
