Migrating Token Contracts to Raydium: Can we enable PDA signing via 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 for migrating 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 via invoke_signed. This may seem counterintuitive at first, but let’s dive into the details and explore why this limitation exists.
Why PDA requires a separate contract
When migrating tokens from one chain to another, you usually create a new token contract in Raydium. However, this process involves creating a new migration contract that contains the logic needed to create, transfer, and store tokens.
To perform these tasks efficiently, you need access to a Programmer Data Address (PDA) contract. This PDA contract is responsible for managing the creation of new tokens on behalf of the Raydium wallet. In Solana, this process typically involves performing a series of invoke_signed calls to delegate the necessary actions to the PDA contract.
Can we enable PDA signing via invoke_signed?
Unfortunately, it is not possible to create a new token contract in Raydium without enabling PDA signing via invoke_signed. This is because the migration_vault, which stores liquidity for the tokens being migrated, is typically a PDA contract that cannot be easily converted to a separate token contract.
Here are some reasons why:
- Programmer Data Address (PDA) Requirements
: The PDA contract for the migration_vault requires access to the programmer’s Solana wallet, which can only be obtained by executing
invoke_signedcalls.
- 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 programmer’s data.
- Chain-Agnostic Requirements: Solana contracts, including migration vaults, must be chain-agnostic, meaning they can operate on multiple chains (e.g. Solana, Binance Smart Chain, etc.). However, creating a new token contract in Raydium requires access to the programmer’s own Solana wallet, which is not chain-agnostic.
Workarounds and Alternatives
In this case, there are possible workarounds and alternatives that you can explore:
- Use an external service: Consider using an external service that provides a PDA contract to create tokens on your behalf, such as OpenBook’s Migration Vault.
- Implement a custom solution: If you are comfortable with the risks involved, you can implement a custom solution to create and manage 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 enable PDA signing directly via invoke_signed, there are workarounds and alternatives available. If you are considering migrating a token contract to Raydium, consider exploring these options or seeking advice from experienced Solana developers. However, if you need to create new token contracts in Raydium, be prepared for the limitations imposed by the PDA requirements.
