Token

¿Qué necesito para comenzar a trabajar con SPL-Tokens?

Cada vez que interactúas con tokens en Solana, en realidad estás interactuando con el token el programa (SPL) Token de Solana, o el estándar SPL-Token. El estándar SPL-Token requiere una librería específica para ser utilizado, la cual puedes encontrar a continuación en función de tu lenguaje.

"@solana/spl-token": "^0.2.0"

¿Cómo crear un nuevo token?

La creación de tokens se realiza creando lo que se llama una cuenta "mint". Esta cuenta "mint" se usa luego para acuñar (o crear y enviar) tokens a una cuenta de token y también para crear el suministro inicial.

¿Cómo obtener un token "mint"?

El suministro actual, autoridad o decimales que tiene un token, los puedes obtener desde la información de cuenta del token "mint".

¿Cómo crear una cuenta de token?

Una cuenta de token es necesaria para almacenar los tokens (una cuenta por cada token). Cada cuenta de token "mint" tiene una cuenta de cuenta de token asociada a ella.

Las cuentas de token asociadas (ATA) se crean de forma determinista para cada par de llaves (keypair). Los ATA son el método recomendado de administrar cuentas token.

Una cuenta token solo puede tener un tipo de mint. Cuando especificas una cuenta de token, también especificas un mint.

¿Cómo cerrar cuentas de token?

Puedes cerrar una cuenta de token si ya no desea usarla. Hay dos situaciones:

Wrapped SOL - Cerrar la cuenta convierte Wrapped SOL to SOL
Other Tokens - La puedes cerrar solo si el saldo de la cuenta está en 0.

¿Cómo establecer la autoridad en cuentas de tokens o mints?

Puede configurar/actualizar la autoridad. Hay 4 tipos:

MintTokens (mint account)
FreezeAccount (mint account)
AccountOwner (token account)
CloseAccount (token account)
