The limitation of the Solana transaction format

Solana, a popular decentralized application platform (DAPP), allows developers to create transactions that can execute multiple functions. However, it also has specific requirements on how these functions are structured. One of those requirements is the field from 'in a transaction.

In this article, we will deepen the PDA de Solana (program data area) with data was not allowed as the 'fromwill be executed.

The “transfer:of "should not carry data"Error

When creating a transaction, Solana requires that the fieldfrom ‘not contain any data. This restriction is intended to ensure that only valid program arguments can be passed through the PDA with data.

However, in some cases, this restriction has been avoided by developers. A recent example of such attempt at the Soleddit of Solana was reported.

THE “PROGRAM 1111111111111111111111111111111111 FALLED: ARGUMENT OF THE NOT VALID PROGRAM” ERROR

The developer behind the problemprogram 1111111111111111111111111111said that they intended to execute a program with data in the field from ‘. Despite this, the transaction failed.

Why wasn’t PDA with data?

To understand why, we need to examine the implementation of Solana of its transaction format. According to Solana’s documentation, transactions are stored in a specific format, which includes:

• The field (required)

• The program identifier

• The arguments of the function

• Any additional data

The 'From must be empty for a valid program argument. If it contains any data, it will result in an error.

Why is this restriction necessary?

This restriction has several purposes:

• Malicious code prevention : Restricing the field `from ‘to empty data, developers can prevent the malicious code from running.

• Ensure the integrity of the program : The restriction guarantees that the programs are executed with valid arguments and do not compromise their integrity.

• Maintaining the solana ecosystem : Restriction helps maintain the stability of the solana ecosystem avoiding the execution of non -valid or malicious programs.

Conclusion

In conclusion, Solana’s ‘from’ field should not carry data is a crucial restriction that guarantees the safety and integrity of its transaction format. The developers trying to avoid this restriction do so at their own risk, since it will result in an error. Following these guidelines, developers can ensure that their programs are executed correctly and safely on the Solana platform.

Additional tips

To avoid similar problems:

• Always read the official documentation for the Solana transaction format.

• Follow best practices by creating transactions to guarantee validity and security.

• Avoid trying to execute non -valid or malicious program arguments.
