As far as I understand, NFTs in TON are just smart contracts that implement a specific interface. Suppose I create a wallet, an explorer or some other produc...

The set_code() function can be used to alter the code of a smart contract. But while it's easy in theory, it would be great to see an example to fully unders...

Consider a situatiton where your Toncoins are used in staking, and someone malicious gets to know your seed phrase. This person can access the wallet, but ca...

Suppose I use getTransactions, but instead of getting all of them I'm interested only ones that happened during the current month. How do I do that? --- > Th...

I'm used to timestamps in Unix time, where digits stand for the seconds passed since 1970. Logical time on TON is also a long number, but it seems different....

One Toncoin consists of one billion (10 to the power of 9) nanotons. So when dealing with Toncoins, you sometimes need to multiply by a billion. What about J...

On the Tonscan and Tonviewer explorers you can find some general stats numbers on TON. But those two websites provide different numbers of addresses. What ca...

It's known that coins in the testnet are not "real". But are the testnet fees in those coins exactly the same as the gas fees in mainnet? If a transaction re...

For many applications it's not reasonable to put all their data on the blockchain. So they need separate hosting for the things like a database, but they mig...

The cell structure on TON has strict limitations, it can contain up to 1023 bits and up to 4 references to other cells. But where does this reference limitat...

Nodes typically use SSDs, because they have faster access speed than HDDs. But an archive node needs lots of space, and SSDs storage is expensive. So maybe t...

I need to send Toncoins to many different wallets at once. So instead of sending lots of transactions one by one, I would be happy to use something that lets...

I'd like to learn developing on TON by creating some small pet projects. What kinds of such projects would be the most helpful and give the most useful exper...

I would like to store data in the smart contract storage in such a way that only the owner of that smart contract could read it. How to achieve it? --- > Thi...

I have a question about the burning mechanism. It seems that the Elector smart contract does not send half of network fees to black hole address. Indeed, the...

Is the https://docs.ton.org/learn/tvm-instructions/tvm-upgrade-2023-07 upgrade really available on testnet? I'm trying to use ECRECOVER but it returns exit s...

In the EVM ecosystems there are oracles like Chainlink that let smart contracts get random numbers from outside of the blockchain. Is there anything like tha...

Blockchains are meant to be trustless, so it's good when the user can check how some smart contract works instead of trusting its author. Verifying smart con...
