Hop Protocol (hop)

Token bridge for rollups using bonders for fast withdrawals. Supports ETH, USDC, USDT, DAI, and MATIC bridging across L2s.

Fact	Value
Category	Bridges
Family	none
Namespace	`Hop` on ethereum, optimism, polygon, base, arbitrum
Chains	ethereum, optimism, polygon, base, arbitrum

Notes

L1-to-L2: Uses sendToL2 on token-specific L1Bridge contracts
L2-to-L2 or L2-to-L1: Uses swapAndSend on L2AmmWrapper (swaps canonical token to hToken for bridging)
Each supported token has separate bridge contracts on L1 and AMM wrappers on L2
Bonders provide fast liquidity on destination (minutes), settle via canonical bridge later
bonderFee on L2 must be obtained from Hop API or SDK
Finality: minutes with bonder, 7+ days without bonder (canonical path)

On Ethereum, Hop is a namespace: its contracts need no import.

function main() {
  // Ethereum's l1EthBridge, `0xb8901acB165ed027E32754E0FFe830802919727f`.
  require(Hop.L1EthBridge != 0);
}
