Migration of token contracts to Raydium: Can we enable PDA signing by Invoke_signed??

As a Solana programmer working with OpenBook, you probably know the migration concept. Migration_vault, which stores all liquidity for migrating tokens from one chain to another, is usually a PDA agreement (programmers' data).

However, when it comes to creating new token contracts in Raydium, we must enable PDA to sign by "Invoke_signed". At the beginning it may seem contrary to intuition, but let's immerse ourselves in detail and examine why this limitation exists.

why PDA requires a separate contract

During the migration of tokens from one chain to another, you usually create a new token agreement in Raydium. This process, however, involves creating a new migration agreement, which contains the necessary logic to create, transfer and store tokens.

To efficiently perform these tasks, you need access to the programmer's data address (PDA). This PDA agreement is responsible for dealing with creating new tokens on behalf of the Raydium portfolio. In sooty, this process usually includes the "Invoke_SIGNED" connection series in order to transfer the necessary actions to the PDA agreement.

Can we turn on the signing of PDA byInvoke_signed`?

Unfortunately, it is not possible to create a new token agreement in Raydium without allowing PDA to sign by "Invoke_SIGNED". This is due to the fact that migration_vault, which stores smoothness for migrating tokens, is usually a PDA agreement that cannot be easily transformed into a separate token agreement.

Here are some reasons:

• 
  Data requirements for programmers (PDA) : PDA agreement for migration_vault requires access to your own Solana portfolio of a programmer, which can only be obtained by making "invoke_signed" connections.

2.

• 
  Chain-agnostic requirements : Solana contracts, including migration_valets, must be chain, which means that they can work on many chains (e.g. salted, intelligent binance chain, etc.). However, the creation of a new token agreement in Raydium requires access to your own Solanian programmer's portfolio that is not chain.

bypassing and alternatives

In this case, there are some possible bypasses and alternatives that you can examine:

• 
  Use an external service : Consider the use of an external service that provides a PDA agreement to create tokens on your behalf, such as your own migration vault OpenBook.

• This would require significant knowledge and may not be practical in the case of large -scale migration.

Application

Although it is not possible to enable the signing of PDA directly via 'Invoke_signed', some bypasses and alternatives are available. If you are planning to migrate the token agreement to Raydium, consider examining these options or searching for tips from experienced Solana programmers. However, if you need to create new token contracts in Raydium, prepare for restrictions imposed by PDA requirements.

I hope it will help! Let me know if you have any questions or need further explanations about any of these points.
