Mikä on pysyvä delegaatti?
Token Extensions Program -ohjelman PermanentDelegate -minttilaajennus
määrittää delegaattiauktoriteetin itse mintille.
Pysyvä delegaatti on minttitason auktoriteetti, joka voi valtuuttaa siirtoja ja polttoja mille tahansa kyseisen mintin token accountille. Se toimii globaalina delegaattina kaikille mintin token accounteille, eikä token account -omistaja voi peruuttaa pysyvää delegaattia token accountiltaan.
Mintin auktoriteetti voi myös vaihtaa pysyvän delegaatin myöhemmin käyttämällä
SetAuthority-toimintoa komennolla AuthorityType::PermanentDelegate.
Pysyvän delegaatin luominen ja käyttäminen
Pysyvän delegaatin luomiseksi ja käyttämiseksi:
- Laske mintin tilin koko ja tarvittava rent mintille ja
PermanentDelegate-laajennukselle. - Luo mintin tili komennolla
CreateAccount, alustaPermanentDelegateja alusta mintti komennollaInitializeMint. - Lähetä
TransferCheckedtaiBurnChecked, jonka on allekirjoittanut pysyvä delegaatti. Token Program käsittelee nämä ohjeet samalla tavalla kuin jos token account -omistaja olisi allekirjoittanut ne.
Laske tilin koko
Laske mintin tilin koko perusmintille sekä
PermanentDelegate-laajennukselle. Tätä kokoa käytetään komennossa
CreateAccount.
Laske rent
Laske rent käyttäen mintille tarvittavaa kokoa sekä
PermanentDelegate-laajennusta.
Luo mintin tili
Luo mint account lasketulla tilalla ja lamporteilla.
Alusta PermanentDelegate
Alusta PermanentDelegate-laajennus mintille.
Alusta mint
Alusta mint InitializeMint-komennolla samassa transaktiossa.
Luo token accountit ja mintaa tokeneita
Luo token accountit omistajalle ja vastaanottajalle, ja mintaa sitten tokeneita omistajan token accountille.
Siirrä pysyvän delegaatin avulla
Siirrä tokeneita TransferChecked-komennolla, jonka pysyvä delegaatti on
allekirjoittanut.
Käskyjen järjestys
InitializePermanentDelegate on suoritettava ennen
InitializeMint-käskyä. CreateAccount,
InitializePermanentDelegate ja InitializeMint on sisällytettävä
samaan transaktioon.
Lähdeviite
| Kohde | Kuvaus | Lähde |
|---|---|---|
PermanentDelegate | Mintin laajennus, joka tallentaa valtuutetun delegaatin kaikille mintin token accounteille. | Lähde |
InitializePermanentDelegate | Käsky, joka alustaa pysyvän delegaatin ennen InitializeMint-käskyä. | Lähde |
SetAuthority | Perus token-käsky, jota käytetään AuthorityType::PermanentDelegate-käskyn kanssa delegaatin vaihtamiseen. | Lähde |
AuthorityType::PermanentDelegate | Valtuutuksen erottelutunniste, jota käytetään SetAuthority-käskyn kanssa mintin pysyvän delegaatin vaihtamiseen. | Lähde |
process_initialize_permanent_delegate | Prosessorilogiikka, joka kirjoittaa pysyvän delegaatin laajennuksen minttiin. | Lähde |
process_set_authority | Prosessorilogiikka, joka validoi ja vaihtaa pysyvän delegaatin, kun AuthorityType::PermanentDelegate-käskyä käytetään. | Lähde |

Alla oleva Kit-esimerkki käyttää generoituja käskyjä suoraan. Vanhat
esimerkit, jotka käyttävät @solana/web3.js- ja @solana/spl-token-komentoja,
on sisällytetty viitteeksi.
