Hop Protocol

What is Hop Protocol?

Hop Protocol is a scalable rollup-to-rollup general token bridge that enables fast and trust-minimized asset transfers between Ethereum Layer 2 networks. Launched in 2021, Hop was one of the first bridges designed specifically for the Layer 2 ecosystem, recognizing that users would need to move assets between Arbitrum, Optimism, and other rollups without going through Ethereum mainnet. The protocol's key innovation is its network of Bonders. Capital providers who front liquidity to users in exchange for fees. This mechanism enables near-instant bridging (within minutes) rather than waiting for the native rollup withdrawal periods (which can take 7 days for Optimistic rollups). Hop uses an AMM model with hTokens. Representations of assets on each supported chain. Users swap between hTokens and canonical assets through liquidity pools, enabling efficient cross-chain transfers. The protocol is governed by the HOP token.

Key Statistics

How Hop Protocol Works

User initiates transfer, Bonder immediately provides hTokens on destination chain, user swaps hTokens for canonical tokens via AMM, original transfer settles through rollup messaging, Bonder reclaims funds once canonical message verified.

hTokens and AMM

Each supported asset has corresponding hTokens on each chain (hETH, hUSDC). AMM pools on each chain contain hToken + canonical token.

Supported Chains

Yield Opportunities

1. AMM Liquidity Provision (5-15% APY)

Provide liquidity to hToken/canonical token pools, earn swap fees from bridge volume, HOP token incentives on select pools.

2. Bonder Operations (Variable)

Run Bonder infrastructure, front capital for bridging, earn Bonder fees.

3. HOP Staking

Stake HOP for governance participation, earn portion of protocol fees.
