ATA所有权变更为令牌程序

Question

我一直在花几个小时试图理解为什么我的ATA地址所有者突然更改为令牌程序而不是我的帐户地址。我正在使用PDA从PDA ATA帐户转移令牌，但由于PDA不再是ATA所有者，因此无法这样做。

我试着测试Anchor来剖析问题并找到解决方案，下面是我的测试控制台日志:

薄荷测试结果:

Mint: A2ojTC6aQZYP6bwUq1FmWN9kwaQTB7NKQmMs89j4FUkx

✔ Mint token! (7001ms)

Mint测试脚本:

it("Mint token!", async () => {
mintPubkey = await createMint(
program.provider.connection, // conneciton
user, // fee payer
user.publicKey, // mint authority
user.publicKey, // freeze authority (you can use `null` to disable it. when you disable it, you can't turn it on again)
9 // decimals
);
console.log("Mint:", mintPubkey.toBase58())
let tokenAccountPubkeyUser = await getOrCreateAssociatedTokenAccount(program.provider.connection, user, mintPubkey, user.publicKey)
console.log("Sender ATA:", tokenAccountPubkeyUser.address.toBase58())
let tokenAuth = await program.provider.connection.getAccountInfo(tokenAccountPubkeyUser.address);
console.log("Sender ATA owner:", tokenAccountPubkeyUser.owner.toBase58())
let tokenAccountPubkeyPda = await getOrCreateAssociatedTokenAccount(program.provider.connection, user, mintPubkey, program.programId)
console.log("program ATA:", tokenAccountPubkeyPda.address.toBase58())
let txhash = await mintToChecked(
program.provider.connection, // connection
user, // fee payer
mintPubkey, // mint
tokenAccountPubkeyUser.address, // receiver (sholud be a token account)
user, // mint authority
100e9, // amount. if your decimals is 9, you mint 10^9 for 1 token.
9 // decimals
);
let tokenSupply = await program.provider.connection.getTokenSupply(mintPubkey);
console.log("Supply:", tokenSupply.value.uiAmount)
txhash = await transferChecked(
program.provider.connection, // connection
user, // payer
tokenAccountPubkeyUser.address, // from (should be a token account)
mintPubkey, // mint
tokenAccountPubkeyPda.address, // to (should be a token account)
user, // from's owner
10e9, // amount, if your deciamls is 9, send 10^9 for 1 token
9 // decimals
);
let tokenAmount = await program.provider.connection.getTokenAccountBalance(tokenAccountPubkeyPda.address);

console.log("PDA:", tokenAmount.value.uiAmount)
let tokenAmountUser = await program.provider.connection.getTokenAccountBalance(tokenAccountPubkeyUser.address);

console.log("User:", tokenAmountUser.value.uiAmount)
})

Remove vault test result:

删除vault测试脚本:

it("User Vault removed!", async () => {
// Add your test here.
// const tx = await program.methods.initializeUser().rpc();
console.log("user:", user.publicKey)
console.log("program:", program.programId)
console.log("token program:", TOKEN_PROGRAM_ID)
console.log("Mint:", mintPubkey.toBase58())

const [userProfilePDA] = await anchor.web3.PublicKey.findProgramAddress([
utf8.encode("USER_STATE"),
user.publicKey.toBuffer(),
],
program.programId
);
console.log("userProfilePDA", userProfilePDA.toBase58());
const userProfile = await program.account.userProfile.fetch(userProfilePDA);
// console.log("UserProfile:", userProfile)
console.log("Last vault:", userProfile.lastVault)
const [vaultAccountPDA] = await anchor.web3.PublicKey.findProgramAddress([
utf8.encode("VAULT_STATE"),
user.publicKey.toBuffer(),
new anchor.BN(0).toBuffer()
],
program.programId
);
console.log("vaultAccountPDA:", vaultAccountPDA.toBase58());
const [vaultInfoPDA] = await anchor.web3.PublicKey.findProgramAddress([
utf8.encode("INFO_STATE"),
// user.publicKey.toBuffer(),
],
program.programId
);
console.log("vaultInfoPDA:", vaultInfoPDA.toBase58());

let tokenAccountPubkeyUser = await getOrCreateAssociatedTokenAccount(program.provider.connection, user, mintPubkey, user.publicKey)

console.log("tokenProgram:", TOKEN_PROGRAM_ID.toBase58())
console.log("receiver ATA:", tokenAccountPubkeyUser.address.toBase58())
let tokenAuth = await program.provider.connection.getAccountInfo(tokenAccountPubkeyUser.address);
console.log("receiver (user) ATA owner:", tokenAuth.owner.toBase58())
let tokenAccountPubkeyVault = await getOrCreateAssociatedTokenAccount(program.provider.connection, user, mintPubkey, vaultInfoPDA, true)

console.log("sender (VaultInfo) ATA:", tokenAccountPubkeyVault.address.toBase58())

let txhash = await transferChecked(
program.provider.connection, // connection
user, // payer
tokenAccountPubkeyUser.address, // from (should be a token account)
mintPubkey, // mint
tokenAccountPubkeyVault.address, // to (should be a token account)
user, // from's owner
10e9, // amount, if your deciamls is 9, send 10^9 for 1 token
9 // decimals
);

let tokenAmount = await program.provider.connection.getTokenAccountBalance(tokenAccountPubkeyVault.address);
console.log("VaultInfo ATA supply:", tokenAmount.value.uiAmount)
tokenAuth = await program.provider.connection.getAccountInfo(tokenAccountPubkeyVault.address);
console.log("VaultATA owner:", tokenAuth.owner.toBase58())
tokenAuth = await program.provider.connection.getAccountInfo(program.programId);
console.log("Program owner:", tokenAuth.owner.toBase58())
tokenAuth = await program.provider.connection.getAccountInfo(vaultInfoPDA);
console.log("vaultInfoPDA owner:", tokenAuth.owner.toBase58())

const tx = await program.rpc.removeVault(0, {
accounts: {
authority: user.publicKey,
userProfile: userProfilePDA,
vaultAccount: vaultAccountPDA,
vaultInfo: vaultInfoPDA,
systemProgram: anchor.web3.SystemProgram.programId,
tokenProgram: TOKEN_PROGRAM_ID,
from: tokenAccountPubkeyVault.address,
to: tokenAccountPubkeyUser.address,
owner: vaultInfoPDA,
// sender: vaultInfoPDA
},
signers: []
})
console.log("Your transaction signature", tx);

});

我希望使用vaultInfoPDA(它应该是ATA的所有者)将令牌发送给删除其保险库的用户。

谢谢!

术语owner在SPL令牌上下文中被重载，这经常引起混淆。

当您在调用getAccountInfo之后记录帐户的owner时，它会给您拥有该帐户的程序，该程序必须是SPL令牌程序。SPL Token程序有权更改帐户中的数据。

在该帐户中也是data。在该数据中，32-64字节定义了可以授权来自帐户(SPL令牌"所有者")的移动的公开密钥。因此，一个帐户中有两个所有者，一个由Solana运行时定义，另一个由SPL Token程序定义。
