## Wallet open orders — GET `/v1/hypercore/wallet/{address}/orders`

One wallet's open orders: resting limit orders and trigger orders, on the main dex and every HIP-3 dex.

Layers: HyperCore. Not on Elysium or HyperEVM: orders, fills and funding payments are HyperCore's: on the EVM layers an address swaps and holds tokens, see its trades, ERC-20 transfers and balances.
