What is Solnet.Serum?

Solnet is Solana's .NET integration library, a number of packages that implement features to interact with Solana from .Net applications.

Solnet.Serum is a package within the same Solnet. namespace that implements a Client for Serum, this project is in a separate repository so it is contained, as the goal for Solnet was to be a core SDK.


  • Decoding of Serum data structures:
    • Market
    • OpenOrdersAccount
    • Slabs, which are used for order book data stored under OrderBookSide and OrderBook which holds both sides
    • EventQueue (Event data, used to process and filter for TradeEvents)
  • SerumProgram instructions implemented:
    • NewOrderV3
    • CancelOrderV2
    • CancelOrderByClientIdV2
    • SettleFunds
    • ConsumeEvents
    • InitOpenOrders
    • CloseOpenOrders
    • Prune
  • SerumClient class which allows to:
    • Get these structures and decode them only by having their address
    • Subscribing to these accounts in real time, getting notifications with their decoded structures
  • MarketManager class which has:
    • Various overloads of NewOrder, NewOrders, CancelOrder and CancelAllOrders, these:
      • craft a transaction or several transactions, in the case where they interact with several orders
      • request a signature using the defined delegate method
      • submit the transaction to the cluster
      • and subscribe to the confirmation of the signature, notifying the user when it happens
      • if the transaction is subject to a custom error defined by the Serum Program here, it is parsed into the appropriate SerumProgramError enum value
  • Factory patterns for both ISerumClient and IMarketManager


  • net 6.0


  • Solnet.Rpc v6.0.13
  • Solnet.Wallet v6.0.13
  • Solnet.Programs v6.0.13


The Solnet.Serum.Examples project features some examples on how to use both the IMarketManager and the ISerumClient, these examples include:

  • Streaming market data directly into user-friendly values using the IMarketManager interface
  • Submitting new orders and cancelling existing ones


We encourage everyone to contribute, submit issues, PRs, discuss. Every kind of help is welcome.
