Description
Hop Protocol is a rollup-to-rollup token bridge that transfers assets between Ethereum and Layer 2 networks through hToken intermediary tokens and per-chain AMMs. Bonders lock collateral to front liquidity at destination chains, issuing hTokens that users swap for native tokens, with collateral released after a 24-hour on-chain challenge window. The protocol includes a dedicated transfer explorer and a protocol metrics dashboard.Category: Bridge

Hop SDK
Project Links
Description
The Hop JavaScript SDK (@hop-protocol/sdk) provides programmatic access to Hop Protocol bridge functionality, enabling developers to integrate cross-chain token transfers into applications. The SDK handles fee calculation, transaction construction, and AMM interactions across all Hop-supported networks and tokens, with npm distribution and a full API reference.Category: Developer Tooling
Hop Core Messenger
Project Links
Description
Hop Core Messenger is a trustless cross-chain messaging protocol using a hub-and-spoke model where messages are aggregated into bundles whose hashes are relayed between networks via native Ethereum bridges. The architecture targets high-security, non-time-sensitive use cases such as DAO governance and value settlement, and supports collateralized or optimistic messaging layers for time-sensitive applications.Category: Cross-chain Infrastructure
