What I'm tryding to achieve is a webpage on which the user connects its phantom wallet and then by a simple press of a button creates a token.
In order to achieve that, I created a simple transaction for now which creates an account for the future token (based on https://www.programcreek.com/typescript/?api=@solana/spl-token.createInitializeMintInstruction)
this is the function which is called when the user press the button:
const onClickCreate = useCallback( async () => {
const lamports = await getMinimumBalanceForRentExemptMint(connection)
const mint = Keypair.generate()
console.log(mint.publicKey.toBase58())
const transaction = new Transaction({feePayer: publicKey})
transaction.add(
SystemProgram.createAccount({
fromPubkey: publicKey,
newAccountPubkey: mint.publicKey,
space: MINT_SIZE,
lamports,
programId: TOKEN_PROGRAM_ID
}),
)
const signature = await sendTransaction(transaction, connection);
await connection.confirmTransaction(signature, 'processed');
}, [publicKey, signTransaction, sendTransaction, connection]);
Executing the code results in the error saying that the signature failed. I use wallet-adapter to connect the user's wallet (which gives me access to the variable publicKey)
If I replace the createAccount function by SystemProgram.transfer everything works ok :
const transaction = new Transaction().add(
SystemProgram.transfer({
fromPubkey: publicKey,
toPubkey: Keypair.generate().publicKey,
lamports: lamportsI,
})
);
Thank you for your time
