DeSo Tokens Transactions API

Description of endpoints used to construct DAO Transactions on the DeSo blockchain

Note: "DAO Coins" are now referred to as "DeSo Tokens" in all public-facing documentation, but the code and API have not yet been updated to reflect this change.

Create DeSo Token (DAO Coin)

POST /api/v0/dao-coin

Create a DeSo Token transaction. Transaction needs to be signed and submitted through api/v0/submit-transaction before changes come into effect.

A mint operation creates new DeSo Tokens

A burn operation destroys DeSo Tokens

An update_transfer_restriction_status operation updates the restrictions on transferring a DeSo Tokens

A disable_minting operation prevents minting of any future DeSo Tokens

Endpoint implementation in backend.

Example usages in frontend: - Make request to DeSo Tokens - Use DeSo Tokens to mint DeSo Tokens - Use DeSo Tokens to burn DeSo Tokens - Use DeSo Tokens to update transfer restriction status - Use DeSo Tokens to disable minting

Create DeSo Token (DAO Coin) Limit Order

POST /api/v0/create-doa-coin-limit-order

Create a new limit order to trade DeSo Tokens. The transaction needs to be signed and submitted through api/v0/submit-transaction before the order can be placed on the book or the coins are traded.

DeSo Tokens can be traded on an on-chain order book exchange. There are two types of markets where DeSo Tokens can be traded on the exchange: 1) markets where a DeSo Token is traded for $DESO, and 2) markets where a DeSo Token is traded for another DeSo Token.

This endpoint allows the creation of limit orders for either type of market.

Endpoint implementation in backend

Request Body

Name	Type	Description
TransactorPublicKeyBase58Check*	String	Public key of the user creating the limit order
BuyingDAOCoinCreatorPublicKeyBase58CheckOrUsername*	String	Public key or username of the creator of a profile, whose DeSo Token is being bought. If the order is selling a DeSo Token for $DESO, then this parameter needs to be an empty string.
SellingDAOCoinCreatorPublicKeyBase58CheckOrUsername*	String	Public key or username of the creator of a profile whose DeSo Token is being sold. If the order is buying a DeSo Token with $DESO, then this parameter needs to be an empty string.
ExchangeRateCoinsToSellPerCoinToBuy*	float64	The desired exchange rate for the coin being sold relative to the coin being bought. The real exchange rate used to fill this order will be equal to or better than the exchange rate provided here, always in the favor of the transactor.
MinFeeRateNanosPerKB*	uint64	Rate per KB
TransactionFees	TransactionFees[]	Array of TransactionFee objects that define additional outputs that need to be added to this transaction
QuantityToFill*	float64	The desired quantity of coins to buy or sell. This is denominated in number of coins (not nanos) and can have fractional values. For example, if you wanted to fill an order of 1 DESO, you would specify 1 here, not 10^9.
OperationType*	string	Supports values "BID" or "ASK". "BID" signifies that this order wants to buy QuantityToFill total coins of the BuyingDAOCoinCreatorPublicKeyBase58CheckOrUsername coin. "ASK" signifies that this limit order wants to sell QuantityToFill total coins of the BuyingDAOCoinCreatorPublicKeyBase58CheckOrUsername coin.

Cancel DeSo Token (DAO Coin) Limit Order

POST /api/v0/cancel-dao-coin-limit-order

Cancel an open limit order to trade DeSo Token. The transaction needs to be signed and submitted through api/v0/submit-transaction before the order is cancelled.

This endpoint allows a transactor to cancel a limit order they had previously created. The request will only succeed if the order is still open, and has not been completely filled or previously cancelled.

See Gets All Open Limit Orders Created by a Transactor for how to retrieve all open orders created by a transactor.

Request Body

Name	Type	Description
TransactorPublicKeyBase58Check*	String	Public key of the user who created the the limit order being cancelled
MinFeeRateNanosPerKB*	uint64	Rate per KB
TransactionFees	TransactionFees[]	Array of TransactionFee objects that define additional outputs that need to be added to this transaction
CancelOrderID*	string	Unique order identifier for the original limit order to cancel. OrderID is also equivalent to the base64 transaction hash hex of the transaction that created the limit order.
