Mikä on oletustilin tila?
Token Extensions Program -ohjelman DefaultAccountState-mintin laajennus
asettaa alkuperäisen AccountState-tilan jokaiselle uudelle token-tilille,
joka luodaan kyseiselle mintille.
Tätä käytetään yleisimmin siihen, että uudet token-tilit alkavat jäädytettynä. Jäädytettynä alkavia token-tilejä ei voi käyttää ennen kuin mintin jäädytysvaltuudet sulattavat ne.
Kuinka luoda mintti oletustilin tilalla
Luodaksesi mintin oletustilin tilalla:
- Laske minttitilien koko ja tarvittava rent mintille ja
DefaultAccountState-laajennukselle. - Luo minttitili
CreateAccount-komennolla, alustaDefaultAccountStateja alusta minttiInitializeMint-komennolla. - Luo token-tilejä mintille ja huomaa, että jokainen uusi token-tili alkaa nykyisestä oletustilasta.
- Käytä
UpdateDefaultAccountState-komentoa muuttaaksesi tilan, josta tulevien token-tilien tulisi alkaa.
Laske tilin koko
Laske minttitilien koko perusmintille lisättynä
DefaultAccountState-laajennuksella. Tätä kokoa käytetään
CreateAccount-komennossa.
Laske rent
Laske rent käyttäen mintille tarvittavaa kokoa lisättynä
DefaultAccountState-laajennuksella.
Luo minttitili
Luo minttitili lasketulla tilalla ja lamporteilla.
Alusta DefaultAccountState
Alusta DefaultAccountState-laajennus mintille.
Alusta mint
Alusta mint InitializeMint-komennon kanssa samassa transaktiossa.
Luo token-tili
Luo token-tili mintille. Koska nykyinen oletustila on Frozen, uusi
token-tili alkaa jäädytettynä.
Päivitä oletustilin tila
Käytä UpdateDefaultAccountState-komentoa muuttaaksesi oletustilaa, jotta
tulevat token-tilit eivät enää ala jäädytettyinä.
Käskyjen järjestys
DefaultAccountStateInstruction::Initialize -komennon on tultava ennen
InitializeMint-komentoa. CreateAccount,
DefaultAccountStateInstruction::Initialize ja InitializeMint
-komennot on sisällytettävä samaan transaktioon.
Lähdeviite
| Kohde | Kuvaus | Lähde |
|---|---|---|
DefaultAccountState | Mint-laajennus, joka tallentaa tilan, jonka uusien token-tilien tulisi periä. | Lähde |
DefaultAccountStateInstruction::Initialize | Käsky, joka alustaa mintin oletusarvoisen token-tilin tilan ennen InitializeMint-komentoa. | Lähde |
DefaultAccountStateInstruction::Update | Käsky, jonka avulla jäädytysvaltuutus voi muuttaa oletustilaa tuleville token-tileille. | Lähde |
process_initialize_default_account_state | Prosessorilogiikka, joka kirjoittaa alkuperäisen oletustilan alustamattomalle mintille. | Lähde |
process_update_default_account_state | Prosessorilogiikka, joka vahvistaa jäädytysvaltuutuksen ennen mintin tallennetun oletustilan muuttamista. | Lähde |

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