I can help you with this. Here is a step -by -step guide on not to handle unauuthorized signatures or entries in Solana contractors:
What is CPI?
CPI means “coin cleaning interface”. This is the Solana contraction function, it is to tell the soer SOL tokens tokens tokens tokens tokens, and the SOL, watch the entre. This can beful to reduce the rice of liquidity.
unauthorized signatories or an accounts saved?
In traditional contracts, signs are required to have specific permissions (e.g. “ISOWER” or “Cansign”) in order to perform specific actions on behalf of the contract. Howver, wen using CPI, you may need to permission to account to the account of the account
Whi is it this a problem?
If the Academy has no permission to sign a transaction or modify the contract, it’s to followal problems:
– in the pool.
- Stability of the contract
: Without appropriate permissions, the account can unexpectedly modify the contract of the contract, causing unintentional behavior and even instability of the contract.
How to Deal without unauthorized signatories or saved accounts in Solan?
To solve that problem, you can with the diversity strategies:
1.
- Implementation of white-country
: Create a list of trasted accounts that havission to the side the transact. Allow new accounts to this if they meet certain criteria (e.g. one has a sulfateent balance, etc.).
3.
- ** Implementation of access control on an account roles (RBAC) Assign powers on the thees roles use the “Isrolemmber” function.
Here is an example of house you can implement whitement water:
`Solana
Whitelist account account {
// List of tried accounts that has been permission to sign the transaction or modact status
mapping (address => bool) пublic white lists;
// Add a new account to the white you are meets specific criteria
Addacunt function (address account, BOOL ISOWNERCANSIGN) Public {
requires (balanced && accont.balance> = 1 ether, "insufficient balance");
Whitelist [account] = True;
}
// allow the academics
ModifigyContractorState (address account) Public Function {
Demand (SW Whitelist [ccount], "not white account");
// Perform the desired action .
}
}
When performing thees and using the example provided, youshuld to a solve the CPI problem related to unauthorized sa-signs.
