Problem with the PA-Digital Assets Contract (PDA)
The Community of Solana has been working to implement PDA contracts, which allow users to store and manage their digital assets decentralized. However, trying these contracts can be a challenge due to several problems.
A common problem found by developers is the use of the macro declare_id of anchor without providing a real identification to declare. In this article, we will address two specific problems with the PDA contract test in Solana: (1) using the macro ‘declares incorrect and (2) the incorrect use of the function’ pubkey ‘of anchor.
Problem 1: Using the Evil Declare_id Macro
When testing a pa-digital asset contract, it is essential to provide real identification to declare. However, some developers use the macro ‘declare_id’ without specifying a valid ID. In this case, the problem arises when the macro declare_id of also returns an error due to missing or non -valid metadata.
To solve this problem, be sure to have used the macro ‘declare_idCorrect and provided a valid identification in the function call declare_id! () . For Example:
oxide
Use Anchor_lag :: Prelude ::*;
Declare_id! («pa_digital_asset_123»);
`
In this example, we declare an id for the pa-digital asset contract using the correct macrodeclare_id.
Problem 2: Incorrect use of thePubkeyof Anchor
Another problemed by developers is the incorrect use of thePubkey ‘function of Anchor. In PDA contracts, it is essential to use the Pubkeya Function when interacting with the Solana Block Chain.
The Pubkey Function Provides Access to a User’s Public Key in the Solana Block Chain. However, some developers incorrectly use this function without specifying the correct key_id.
To solve this problem, be sure to have used the Pubkey Correct and provided the required ‘key_id. For Example:
oxide
Use Anchor_lag :: Prelude ::*;
Declare_id! («pa_digital_asset_123»);
Let pda_contract = solana_pda :: PDA :: PDACTRACT :: NEW (
& Key :: From («pa_digital_asset_123»),
Key :: From («0x1234567890ABCDEF»),
);
`
In this example, we declare an id for the pa-digital asset contract using the macro 'declare_id correct and specify a valid key. Then, we use the Pubkey Correct to access the PDA Contract.
Following these steps, you can solve common problems encountered by developers when trying PDA contracts in Solana.
