Smart Contracts

HyperLink's on-chain smart contracts on HyperEVM: addresses and purpose for deposits, withdrawals, fees, enclave verification, and hlHYPE staking.

HyperLink's on-chain contracts run on HyperEVM and handle deposits, withdrawals, fees, enclave verification, reserve commitments, and hlHYPE staking. Trading and balances stay private inside the enclave. On Hyperliquid, the relay operates in Standard account abstraction mode.

All contracts sit behind upgradeable proxies. Use the proxy address below; it is the stable, user-facing address.

Native HYPE

The contracts represent native HYPE with this sentinel address:

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE

Treat that address as native HYPE wherever a token address is expected (for example, deposit and fee accounting).
