Porting Token Contracts to Raydium: Can We Enable PDA Signing Using Invoke_signed?
As a Solana developer working with OpenBook, you are probably familiar with the concept of a migration vault. The migration_vault, which stores all the liquidity needed to transfer tokens from one chain to another, is usually a PDA (Programmer Data Address) contract.
However, when it comes to creating new token contracts in Raydium, we need to enable PDA signing using “invoke_signed”. This may seem contradictory at first, but let’s dive into the details and find out why such a restriction exists.
Why do we need a separate contract for PDA?
When you move tokens from one chain to another, you usually create a new token contract on Raydium. However, this process involves creating a new transfer contract that contains the logic to create, transfer, and store the access key.
To perform these tasks effectively, you need access to a programmer data address contract (PDA). This PDA contract is responsible for creating new tokens on behalf of the Raydium wallet. In Solana, this process typically involves a series of “invoke_signed” calls to pass the necessary operations to the PDA contract.
Can we enable PDA signing using “invoke_signed”?
Unfortunately, it is not possible to create a new token contract in Raydium without enabling PDA signing using “invoke_signed”. This is because the migration_vault, which stores the liquidity of the migrated tokens, is typically a PDA contract that cannot be easily converted into a standalone token contract.
Here are some reasons why:
- Developer Data Address (PDA) Requirements: The PDA contract for migration_vault requires access to the developer’s own Solana wallet, which can only be accessed via invoke_signed calls.
- Token Creation and Transfer Logic: Creating new tokens in Raydium involves executing specific logic that cannot be easily replicated without a separate token contract with access to the developer’s data.
- Chain-Agnostic Requirements: Solana contracts, including migration_vaults, must be chain-agnostic, meaning they can run on multiple chains (e.g. Solana, Binance Smart Chain, etc.). However, creating a new token contract on Raydium requires access to the developer’s own Solana wallet, which is not chain-agnostic.
Issues and Alternatives
In this case, there are several possible workarounds and alternatives that are worth exploring:
- Using an external service
: Consider using an external service that provides a PDA contract to create the token on your behalf, such as the OpenBook Transfer Repository.
- Installing a custom solution: If you are comfortable with the risks involved, you can install a custom solution to create and manage access token contracts in Raydium. This would require significant expertise and may not be practical for large-scale migrations.
Conclusion
While it is not possible to directly enable PDA signing using invoke_signed, there are several workarounds and potential alternatives. If you are planning to migrate your token contract to Raydium, consider exploring these options or seeking advice from experienced Solana developers. However, if you need to create new token contracts on Raydium, be prepared for the limitations imposed by the PDA requirements.
I hope this helps! If you have any questions or need further clarification, please let me know.
