DEX module
The
dex module is responsible for order placement and related trading functionality. One can build exchange dapp based this module. You can also find more details here.To interact with the dex module, one can use either a
query or tx message. Below are examples of how to interact, along with a brief overview of some common enums and structs used in the Appendix. Note that these commands have the usual other flags such as --from, --chain_id, -fees, --gas, --broadcast-mode, etc.Description: gets time weighted average prices for specific assets
Usage:
seid q get-twaps $contract_addr $lookbackArguments: 1) contract address (string), 2) lookback (uint64)
Returns:
Twap[]Example:
seid q get-twaps $contract_addr 100 --from=$key_name --chain_id=sei_chain --fees=1000000usei --gas=50000000 --broadcast-mode=blockDescription: get orders by a specific account on the order book
Usage:
seid q get-orders $contract_addr $accountArguments: 1) contract address (string), 2) account (string)
Returns: Orders[]
Example:
seid q get-orders $contract_addr $acc_addr --from=$key_name --chain_id=sei_chain --fees=1000000usei --gas=50000000 --broadcast-mode=blockDescription: get individual order by order ID
Usage:
seid q get-orders-by-id $contract_addr $price_denom $asset_denom $idArguments: 1) contract address (string), 2) price_denom (string), 3) asset_denom (string), 4) id (uint64)
Returns: Order
Example:
seid q get-orders-by-id $contract_addr 'USDC' 'ATOM' $id --from=$key_name --chain_id=sei_chain --fees=1000000usei --gas=50000000 --broadcast-mode=blockDescription: places orders with the order book
Usage:
seid tx place-orders $contract_addr $orders --amount $coins (optional)Arguments: 1) contract address (string), 2) list of orders
Note: orders arguments are split by a ?, and the following holds: position direction is arg[0], price is arg[1], quantity is arg[2], price denom is args[3], asset denom is args[4], order type is args[5], and data is args[6]
Returns:
uint64[] OrderIdsExample:
seid tx dex place-orders $contract_addr 'LONG?1.01?5?USDC?ATOM?LIMIT?{"leverage":"1","position_effect":"Open"}' --amount=1000000000uusdc -y --from=$key_name --chain_id=sei_chain --fees=1000000usei --gas=50000000 --broadcast-mode=block Description: Bulk cancel orders with the dex order book
Usage:
seid tx cancel-orders $contract_addr $cancellationsArguments: 1) contract address (string), 2) list of cancellations
Note: cancellation arguments are split by a ?, and order id is arg[0], position direction is arg[1], price is arg[2], price denom is args[3], asset denom is args[4]
Returns: None (
type MsgCancelOrdersResponse struct {})Example:
seid tx dex cancel-orders $contract_addr '1?LONG?1.01?USDC?ATOM' --from=$key_name --chain_id=sei_chain --fees=1000000usei --gas=50000000 --broadcast-mode=block
