Solana: CPI with unauthorized signer or writable account
Februari 7, 2025 | by Gusri Efendi
I can help you with it. Here is a step -by -step guide on how to handle unauthorized signatories or written accounts in Solana Agreements:
What is CPI?
The CPI denotes the “coin purification interface”. This is the function of Solana’s contracts that allow users to deposit their solo markers in the pool and then remove them as a bench without using the entire pool. This can be helpful in reducing the risk of liquidity.
Unauthorized signatories or written accounts?
In traditional solan, signatories must have special permits (eg Isowneror '' Cansign ') in order to take certain actions on behalf of the contract. However, when using the PCI, you may need to allow the account to be a signatorial or written account.
Why is this problem?
If the account does not have permission to sign transactions or modify the contract position, this may raise several questions:
1
Liquidity risk : If the account does not have permission to deposit and remove the Sol tokens, they may accidentally pay more promise than expected by reducing the liquidity in the pool.
- Stability of the Agreement : Without proper permits, the account may unexpectedly change the position of the contract, leading to unexpected action or even instability of the contract.
How to deal with unauthorized signatories or written accounts Solana?
You can use the following strategies to solve this problem:
- UseIsawner
and 'CANSIGNwith caution : Make sure these permits are granted only to the authorized parties.
- Introduce the White List of Account
: Create a reliable list of accounts that have permission to sign transactions or modify the contract position. Allow this list to add new accounts only if they meet special criteria (for example, there is sufficient balance, etc.).
3
Use WritableAccount Property : Use the property“ WritableAccount ”in Solana Agreement to enable written accounts to one account.
- implement account -based access control (RBAC) : Define roles for different types of accounts (such as depositors, removal, etc.). Give permits based on these roles using the “Isrolemember” function.
Here is an example of how you can introduce the White List of Account:
`Solana
Agreement Account Baltist {
// List of trusted accounts that have permission to sign transactions or modify the position of a contract
mapping (address => bool) public white list;
// Add a new account to the white list if it meets special criteria
Function Addaccount (address account, bool isownerorcansign) public {
request (isownororcansign && account.Balance> = 1 ether, “Insufficient balance”);
White list [account] = true;
}
// Allow the account to modify the position of the contract if they are in the White List
Function ModifyConcractState (address account) public {
request (SW White List [Account], “Account not White List”);
// Do the desired action here …
}
}
`
When performing these actions and using an example, you should be able to solve the PCI problem associated with unauthorized signatories or written accounts in your solan.
