Impostare l'autorità

Cosa Fa l'Impostazione dell'Autorità?

L'impostazione dell'autorità modifica o revoca ruoli di autorità specifici su un mint account o token account.

I mint account possono memorizzare un'autorità di conio e un'autorità di congelamento. I token account memorizzano un proprietario e possono facoltativamente memorizzare un'autorità di chiusura. Ogni ruolo controlla un set di permessi specifico, e impostare un'autorità su None rimuove permanentemente il ruolo di autorità selezionato.

Il Token Extensions Program definisce anche tipi di autorità aggiuntivi per estensioni specifiche.

Come Impostare l'Autorità

La modifica di un'autorità utilizza l'istruzione SetAuthority del Token Program.

Ogni chiamata aggiorna un tipo di autorità su un mint account o token account. L'autorità corrente firma la modifica, e la nuova autorità può essere un altro indirizzo o None per revocare permanentemente l'autorità selezionata.
