Solana’s nostal custody area (Nostend) is a new API with which developer Nostr, the decentralized identity platform of Solana, can create and interact. However, I could not find an official documentation in the function SOL_INVOKE_SIGNED_C SYSCALL in the nostentation environment.
While you have tried to use this function, an error message is displayed that indicates that a required signature for the instruction is missing. This indicates that the system call from Sol_invoke_signed_c is not available or is not compatible with its version of Solana.
Here is an article that offers insights and possible solutions:
Title: pda -samen and bump to sol_invoke_signed_c syscall in Solana_nostd_entrypoint Use: missing signature for instructions
Introduction:
Creating a personal delegation account (PDA) on Solana includes several steps, including the provision of a program with the API “Solana_nostd_entrypoint”. During this approach, it enables flexibility and adaptation, it also requires knowledge of the underlying NOSR entry point environment.
In recent updates, Solana has introduced new functions and APIs to simplify the process. However, some developers have reported problems with the lack of necessary signatures when using certain system calls. In this article we will examine the problem with SOL_INVOKE_SIGNED_C SYCALL in the Solana_nostd_entrypoint area and provide some possible solutions.
The problem:
When creating a PDA account in Solana, you have to provide a program with the “Soluna_Program :: zurypoint :: Solve” function. This includes the handover of parameters such as the metadata of the PDA, the seeds and the bump value. The system call from Sol_invoke_signed_c 'is used to interact with NOSTR, but a certain signature must be handed over.
However, some developers have reported that this system call is missing a necessary signature for instructions. This error message indicates that you have to specify the correct signature when callingSol_invoke_signed_c.
Possible solutions:
To solve the problem, you can try out the following solutions:
- Check the official documentation: While the official documentation of Solana may not mention this specific error, it is always a good idea to check the latest updates and changes.
- Instead, use the "Einypoint :: Call" function: if possible, you should use the "EinPypoint :: Call" function from the API "Solana_nostd_entrypoint", which enables more flexibility and adaptation.
- Enter the correct signature: Make sure you hand over the required signature if you callSol_invoke_signed_c. You can check the documentation or contact the Solana community to check the correct signature.
Diploma:
Creating a PDA account in Solana requires some knowledge of the underlying NOSR entry point environment, but it is not impossible. By understanding the problems and potential solutions described in this article, you should be able to fix the error and successfully provide your program with Soluna_Program :: zurypoint :: lelve.
However, if you are new with Solana Development or the Nostend -API, it may be helpful to explore other resources and documentation in order to learn more about the latest functions and best practice.
Additional resources:
- Official Solana documentation: [Solana documentation] (
- Solana community forums: [Solana Forum] (
- Nostr documentation: [nostr -api -documentation] (
If you follow these steps and consult the official documentation, you should be able to dissolve the error of `Sol_invoke_Signed_c Syscall ‘when creating a PDA account on Solana.
