cWithdraw - Withdraw Collateral

The cWithdraw action records collateral leaving the lending side of a Hyperliquid account. Dwellir exposes that payload through HyperCore gRPC methods such as StreamBlocks and GetBlock, so you can track collateral withdrawals in real time.

How to Read It

The action body contains the raw withdrawal amount and chain-scoping fields used during signing. The execution result arrives separately through the matching resps.Full entry, so indexers should always pair the action and response before labeling a withdrawal as successful.

Processing Guidance

• wei is not a user-ready decimal string. Convert it with the asset metadata your application already maintains.
• Join the action to the paired response before alerting on a withdrawal. A signed action appearing in the block stream is not the same as a confirmed state change.
• Track the nonce and transaction link when building audit trails for collateral movements.
• Interpret cWithdraw together with cDeposit and borrowLend when reconstructing lending account state.

Common Use Cases

Exposure Reduction Tracking

Watch for users removing collateral after repaying loans or de-risking positions.

Post-Trade Settlement Analysis

Correlate withdrawals with earlier lending actions to understand capital leaving the collateral pool.
