You can use each submodule individually. Click the module below to get more details.

• Tonlib - use external Tonlib shared library to communicate with TON blockchain.
• SmartContract - create and deploy custom and predefined smart-contracts.
• Cell - create, read and manipulate Bag of Cells.
• BitString - construct bit-strings.
• Address - create and parse TON wallet addresses.
• Mnemonic - helpful methods for generating deterministic keys for TON blockchain.
• Emulator - wrapper for using with external precompiled emulator shared library.
• Liteclient - wrapper for using with external precompiled lite-client binary.
• Utils - create private and public keys, convert data, etc.

Features

• ✅ BitString manipulations
• ✅ Cells serialization / deserialization
• ✅ TL-B serialization / deserialization
• ✅ Cell builder and cell slicer (reader)
• ✅ Tonlib wrapper
• ✅ Lite-client wrapper
• ✅ Support num, cell and slice as arguments for runMethod
• ✅ Render List, Tuple, Slice, Cell and Number results from runMethod
• ✅ Generate or import private key, sign, encrypt and decrypt using Tonlib
• ✅ Encrypt/decrypt with mnemonic
• ✅ Send external message
• ✅ Get block transactions
• ✅ Deploy contracts and send external messages using Tonlib
• ✅ Wallets - Simple (V1), V2, V3, V4 (plugins), Lockup, Highload/Highload-V3, DNS, Jetton, StableCoin, NFT, Payment-channels, Multisig V1
• ✅ HashMap, HashMapE, PfxHashMap, PfxHashMapE, HashMapAug, HashMapAugE serialization / deserialization

Todo

ton4j's Issues

How to parse cell

How to parse the payload from the boc obtained after tonconect is used to pay ton

Wrong calculation of cells during serialization of cell with dictionary

Tree-walk of the cell returns a 3 times bigger amount of cells than entries in the dictionary.
Due to this bug Highload wallet can send up to 253/3=84 messages
To reproduce run the below test with higher number of wallets
TestWalletV2Highload.testWalletV2HighloadSendTo84()

Verifying signed in users on backend

verify a user to provide them with their personal information from the back end.

Is there a plan to implement this?

Tks!

Why is there an error in specifying my address to obtain transactions, and how to solve it

the following code executes normally,when the address is changed to “kQD6P-Dg6BoyFEdd4UFvupex_cPToZ1D6YqOrXpBG_P1GaTQ” and get: lite server cannot return any transactions

Address address = Address.of("EQCD39VS5jcptHL8vMjEXrzGaRcCVYto7HUn4bpAOg8xqB2N");
RawTransactions rawTransactions = tonlib.getRawTransactions(address.toString(false), null, null, 3);
for (RawTransaction tx : rawTransactions.getTransactions()) {
if (nonNull(tx.getIn_msg()) && (!tx.getIn_msg().getSource().getAccount_address().equals(""))) {
LastTransactionId ttx = tx.getTransaction_id();
System.out.println(Utils.toUTC(tx.getUtime())+", "+Utils.base64ToHexString(ttx.getHash())+" "+tx.getIn_msg().getSource().getAccount_address()+" <<<<< "+tx.getIn_msg().getDestination().getAccount_address()+":"+Utils.formatNanoValue(tx.getIn_msg().getValue()));
}
if (nonNull(tx.getOut_msgs())) {
for (RawMessage msg : tx.getOut_msgs()) {
System.out.println(Utils.toUTC(tx.getUtime())+", "+ msg.getSource().getAccount_address()+" >>>> "+ msg.getDestination().getAccount_address()+":"+Utils.formatNanoValue(msg.getValue()));
}
}
}

address parameters

please tell me how to get a list of all tokens and their denominations belonging to the address?
Also in the address parameters there are CODE and DATA fields, what do they contain?

How to calculate the commission for a transfer transaction from a V4R2 wallet

How to calculate the commission for a transfer transaction from a V4R2 wallet?

Cannot invoke "org.ton.java.tonlib.types.LastTransactionId.getLt()"

java.lang.NullPointerException: Cannot invoke "org.ton.java.tonlib.types.LastTransactionId.getLt()" because the return value of "org.ton.java.tonlib.types.FullAccountState.getLast_transaction_id()" is null
at org.ton.java.tonlib.Tonlib.getRawTransactions(Tonlib.java:510)

This code gives an error:

val tonlib: Tonlib = Tonlib.builder().build()
val address: Address = Address.of("EQA870ez59EjeBmDNWBaQhvUTeGRKeJYJbJ_quKgCT__UjWr")
val rawTransactions = tonlib.getRawTransactions(address.toString(false), null, null)

Is this a bug or is it supposed to be like this?
This does not always happen. If you call the function a second time, everything works fine.

mnemonic phrase and wallet addresses

Please explain why, when using the same mnemonic phrase, tonlib_cli, tonlibjson, and official wallets produce different addresses?

how to obtain the correct wallet v4r2 address use mnemonics

i can't get the correct wallet address using the following code,:
Tonlib tonlib = Tonlib.builder().pathToTonlibSharedLib("~/tonlibjson.dylib").testnet(true).ignoreCache(true).build();
String mnemonicStr = "24 words mnemonic here";
List mnemonics = Arrays.stream(mnemonicStr.split(" ")).toList();
Pair pair = Mnemonic.toKeyPair(mnemonics);
TweetNaclFast.Signature.KeyPair keyPair = TweetNaclFast.Signature.keyPair_fromSeed(pair.getSecretKey());
WalletV4R2 contract = WalletV4R2.builder()
.tonlib(tonlib)
.keyPair(keyPair)
.walletId(0)
.build();
Address walletAddress = contract.getAddress();
String address = walletAddress.toString(true,true,true,true);
