CoreWriter

CoreWriter is a Hyperliquid system contract at 0x3333333333333333333333333333333333333333. Smart contracts deployed on HyperEVM call into CoreWriter to send actions to HyperCore: placing limit orders, transferring spot tokens, staking HYPE, managing vaults. Each CoreWriter call burns about 25,000 gas and emits a log that HyperCore picks up in the next block. Note that a CoreWriter call may succeed at the EVM layer while the HyperCore action it triggers later fails — the two outcomes are independent.
