Token
Tôi nên cần gì để bắt đầu với SPL-Tokens?
Mỗi khi bạn tương tác với token trên Solana, bạn thực chất đang tương tác với Solana Program Library Token, gọi tắt là SPL-Token Standard. Chuẩn SPL-Token yêu cầu một thư viện đặc thù để sử dụng và bạn có thể tìm thấy bên dưới tuỳ vào ngôn ngữ lập trình của bạn.
"@solana/spl-token": "^0.2.0"
Làm thế nào để tạo một token mới
Tạo mới token có thể thực hiện bằng cách tạo một "mint account". Account này sẽ được sử dụng lưu đúc token cho token account và ghi nhớ tổng cung cung khởi tạo.

Làm thế nào để đọc truy vấn token mint
Để có thể đọc tổng cung hiện tại, chủ sở hữu, hoặc số chữ số phần thập phân (decimals) mà token định nghĩa, bạn sẽ cần lấy dữ liệu dữ liệu mint account.
import { clusterApiUrl, Connection, PublicKey } from "@solana/web3.js";
import { getMint } from "@solana/spl-token";
(async () => {
const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
const mintAccountPublicKey = new PublicKey("8mAKLjGGmjKTnmcXeyr3pr7iX13xXVjJJiL6RujDbSPV");
let mintAccount = await getMint(connection, mintAccountPublicKey);
console.log(mintAccount);
/*

}
}
*/
})();
let mintAccount = await getMint(connection, mintAccountPublicKey);
Làm thế nào để tạo một token account
Một token account là bắt buộc cần có để chứa tokens. Mỗi token mint có một token account khác nhau tương ứng với nó.
Associated Token Accounts (ATA) được tạo một cách "bất biến" cho các cặp khoá. ATA là phương pháp khuyên dùng để quản lý token account.

const mintPubkey = new PublicKey(

);
// 1) use build-in function
{
let ata = await createAssociatedTokenAccount(

}
Làm thế nào để truy vấn token acount
Mỗi token account chứa thông tin về chủ sỡ hữu token, loại mint, só dư, và số chữ số phần thập phân.
import { clusterApiUrl, Connection, PublicKey } from "@solana/web3.js";
import { getAccount } from "@solana/spl-token";
(async () => {
const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
const tokenAccountPubkey = new PublicKey(
"2XYiFjmU1pCXmC2QfEAghk6S7UADseupkNQdnRBXszD5"
);
let tokenAccount = await getAccount(connection, tokenAccountPubkey);
console.log(tokenAccount);
/*

isInitialized: true,
isFrozen: false,
isNative: false,
rentExemptReserve: null,
closeAuthority: null
}
*/
})();
let tokenAccount = await getAccount(connection, tokenAccountPubkey);
Làm thế nào để truy vấn số dư của token account
Thông tin số dư token của một token account có thể được truy vấn bằng một hàm gọi duy nhất.
import { clusterApiUrl, Connection, PublicKey } from "@solana/web3.js";
(async () => {
const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
const tokenAccount = new PublicKey(
"FWZedVtyKQtP4CXhT7XDnLidRADrJknmZGA2qNjpTPg8"
);
let tokenAmount = await connection.getTokenAccountBalance(tokenAccount);
console.log(`amount: ${tokenAmount.value.amount}`);
console.log(`decimals: ${tokenAmount.value.decimals}`);
})();
let tokenAmount = await connection.getTokenAccountBalance(tokenAccount);
use solana_client::rpc_client::RpcClient;
use solana_program::pubkey::Pubkey;
use solana_sdk::commitment_config::CommitmentConfig;
use std::str::FromStr;
fn main() {
let rpc_url = String::from("https://api.devnet.solana.com");
let connection = RpcClient::new_with_commitment(rpc_url, CommitmentConfig::confirmed());
let token_account = Pubkey::from_str("FWZedVtyKQtP4CXhT7XDnLidRADrJknmZGA2qNjpTPg8").unwrap();
let balance = connection
.get_token_account_balance(&token_account)
.unwrap();
println!("amount: {}, decimals: {}", balance.amount, balance.decimals);
}
let balance = connection
.get_token_account_balance(&token_account)
.unwrap();
TIP
Một token account chỉ có thể chứa một loại mint duy nhất. Khi bạn khai báo token account, bạn cũng phải chỉ rõ lại mint.
Làm thế nào để dúc token
Khi bạn đúc token, bạn tăng số lượng tổng cung và chuyển số lược token mới cho token account mong muốn.

Làm thế nào để đóng một token account
Bạn có thể đóng một token account nếu bạn không muốn dùng nó nữa. Sẽ có 2 trường hợp:
- Wrapped SOL - Đóng và chuyển Wrapped SOL thành SOL
- Các Token khác - Bạn có thể đóng chỉ khi số dư của token account là 0.

Làm thế nào để uỷ quyền cho một token đại diện (delegate)
Bạn có thể thiết lập một đại diện với một số lượng cho phép. Sau khi thiết lập xong, người đại diện sẽ giống như một chủ sỡ hữu khác của token account của bạn. Một token account chỉ có thể uỷ quyền cho một account tại một thời điểm

Làm thế nào để thu hồi một token đại diện
Thu hồi sẽ thiết lập biến delegate
về null
và số dư uỷ quyền về 0.

Làm thế nào để quản lý wrapped SOL
Wrapped SOL cũng chỉ giống như các lại token mint khác. Điểm khác là bạn có thể sử dụng syncNative
và tạo token account dựa trên địa chỉ NATIVE_MINT
.
Tạo token account
Tương tự Làm thế nào để tạo một token account nhưng thay địa chỉ mint với NATIVE_MINT
import { NATIVE_MINT } from "@solana/spl-token";
Thêm số dư
Có hai cách để thêm số dư cho Wrapped SOL
1. Bằng cách chuyển SOL
import {
clusterApiUrl,
Connection,
Keypair,
Transaction,

} from "@solana/web3.js";
import {
NATIVE_MINT,

)
);
// remember to create ATA first
let ata = await getAssociatedTokenAddress(
NATIVE_MINT, // mint
alice.publicKey // owner
);
let amount = 1 * 1e9; /* Wrapped SOL's decimals is 9 */
let tx = new Transaction().add(
// trasnfer SOL
SystemProgram.transfer({
fromPubkey: alice.publicKey,
toPubkey: ata,
lamports: amount,
}),
// sync wrapped SOL balance
createSyncNativeInstruction(ata)
);
console.log(
`txhash: ${await connection.sendTransaction(tx, [feePayer, alice])}`
);
})();
let tx = new Transaction().add(
// trasnfer SOL
SystemProgram.transfer({
fromPubkey: alice.publicKey,
toPubkey: ata,
lamports: amount,

// sync wrapped SOL balance
createSyncNativeInstruction(ata)

Làm thế nào để truy vấn tất cả token account của một Chủ
Bạn có thể truy vấn tất cả token account của cùng một chủ. Có 2 cách để thực hiện.
- Lấy tất cả token account
import { clusterApiUrl, Connection, PublicKey } from "@solana/web3.js";
import { TOKEN_PROGRAM_ID } from "@solana/spl-token";
import * as bs58 from "bs58";
(async () => {
// connection
const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
const owner = new PublicKey("G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY");
let response = await connection.getParsedTokenAccountsByOwner(owner, {
programId: TOKEN_PROGRAM_ID,
});
response.value.forEach((accountInfo) => {
console.log(`pubkey: ${accountInfo.pubkey.toBase58()}`);
console.log(`mint: ${accountInfo.account.data["parsed"]["info"]["mint"]}`);
console.log(
`owner: ${accountInfo.account.data["parsed"]["info"]["owner"]}`
);
console.log(
`decimals: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["decimals"]}`
);
console.log(
`amount: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["amount"]}`
);
console.log("====================");
});
})();
let response = await connection.getParsedTokenAccountsByOwner(owner, {
programId: TOKEN_PROGRAM_ID,
});
- Lọc bằng mint

let response = await connection.getParsedTokenAccountsByOwner(owner, {
mint: mint,
});
response.value.forEach((accountInfo) => {
console.log(`pubkey: ${accountInfo.pubkey.toBase58()}`);
console.log(`mint: ${accountInfo.account.data["parsed"]["info"]["mint"]}`);
console.log(
`owner: ${accountInfo.account.data["parsed"]["info"]["owner"]}`
);
console.log(
`decimals: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["decimals"]}`
);
console.log(
