The concept of PodMint vs Mint is to allow for in-place / zero-copy deserialization, which uses much fewer compute units on-chain. If you want to do things in-place, then you can use the Pod variants. …

USDT and USDC do not support confidential transfers. You will have to create a new mint with confidential transfers enabled and wrap USDC or USDT with a separate smart contract yourself if you want th …

There's a couple of questions here, so to separate them out: The account data too small for instruction error probably comes from trying to deploy a larger program than the default one provided. The g …

Once a token mint is initialized, it's not possible to add a transfer hook. Almost all extensions must be configured prior to initialization. But once you're ready to create your next token, you can l …

The big difference between Ethereum and Solana is how account data is read. On Ethereum, you have view functions, so the amount can be calculated by the smart contract, whereas on Solana, programs and …

Your best bet is to read through the confidential token documentation, which provides all of the required proofs and further documentation. Here's the documentation on the equality proofs: https://spl …

It roughly boils down to: import { clusterApiUrl, sendAndConfirmTransaction, Connection, Keypair, SystemProgram, Transaction, } from '@solana/web3.js'; import { createIniti …

If you want to use token-2022 to create your token, you'll need to do a few things during your call to create-token: specify --program-id TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb add any flags for …

You have three different options: requesting the account with jsonParsed encoding should parse all of the extension data for you in Rust: use spl_token_2022::{ extension::{BaseStateWithExtension …

You've figured it all out! The CLI will create the extra-metas account at the proper address, and the whole point of the [<ACCOUNT_PUBKEY>:<ROLE> ...] is to specify the additional accounts required by …

If you want your program to work with the metadata-pointer extension, there's no requirements at all! It's just a dumb pointer that can point anywhere. The concept is that it points to a metadata acco …

In order to create a correct transfer instruction, you must fetch all of the additional required accounts and add them to the instruction. The Rust crates currently expose some helpers to make this ea …

This won't be possible with a transfer hook. Remember that only a program that owns an account can modify its contents. In the case of token-2022, this means that only token-2022 can modify the balanc …

There's no mechanism to make that obvious at the moment, but perhaps a standard will emerge for "tokens that require additional approval before transferring", along with some tooling for using these k …

It's a bit tricky -- this is only possible if you have access to the secret key for the ElGamal key on the account owned by the PDA. By default, the ElGamal key is derived from the owner, so you'll h …
