The CoreWriter system contract was activated on mainnet two weeks ago. CoreWriter and read precompiles allow trustless two-way communication between HyperCore and the HyperEVM, enabling builders to create an entirely new class of HyperEVM applications that interact with the liquidity and performance of HyperCore. For example, LSTs on other chains are usually controlled by an offchain multi-sig because staking occurs outside of the VM. The next generation of Hyperliquid LSTs can be built using read precompiles and CoreWriter for an entirely onchain tokenized staking experience. Furthermore, these onchain LSTs can participate in staking-related functionality through actions initiated from the HyperEVM, such as onchain LST-holder governance to deploy HIP-3 assets. As another example, borrow lend protocols can use read precompiles to incorporate prices from order books on HyperCore into more robust oracle prices. CoreWriter then allows these protocols to trustlessly liquidate undercollateralized positions on HyperCore order books. The seamless composability of HyperCore and the HyperEVM will be essential to enabling builders and bringing finance onchain.
