TONNode — TON blockchain access

Full account state of a TON address: status (active / frozen / uninit), GRAM balance, last-transaction pointer (lt + hash) and whether contract code/data are deployed. Use when: checking if a contract or wallet is deployed, diagnosing why an address does not respond, or before run_get_method (which needs status=active). Returns: status, balance_gram, last_transaction {lt (string), hash — 64-char hex}, has_code, has_data, at_seqno. Reading the result: status=uninit with a non-zero balance means funds arrived but the wallet contract is not deployed yet; the last_transaction pointer is the cursor get_transactions starts from.

Native GRAM coin balance of a TON address (GRAM is the renamed Toncoin; the network is still called TON). Use when: the question is about the native coin only. For token balances (USDT and other jettons) use get_jetton_balance; for deployment status, code flags and the last transaction use get_account_state. Returns: balance_gram (decimal string, e.g. "12.5"), balance_nano (string, 1 GRAM = 1e9 nano) and at_seqno — the masterchain block the reading is anchored to. Never-funded (uninitialized) addresses return 0 — that is not an error.

Jetton (TON token) balance of an owner address — USDT and every other TEP-74 token. Use when: the question is about token balances rather than the native GRAM coin (for GRAM use get_balance). Args: owner — the holder's address; jetton_master — the token's master contract address. How it works: derives the owner's jetton-wallet address from the master, then reads its balance on-chain. Returns: jetton_wallet (the derived address), balance in raw indivisible units (string), deployed — false means the owner never held this token, so the balance is 0 — and at_seqno. Raw units: divide by 10^decimals; USDT uses 6 decimals, most other jettons 9 (read decimals from the master's metadata via run_get_method get_jetton_data).

Latest TON masterchain block: workchain, shard, seqno and block hashes. Use when: checking that the network (or your endpoint) is alive and synced, or when you need the current block height. Returns: workchain, shard, seqno, rootHash/fileHash in base64. Tip: masterchain produces a block roughly every 3 seconds — if seqno does not grow between calls, the liteserver is lagging.

Recent transactions of a TON address, newest first. Use when: verifying that a payment arrived, listing latest wallet activity, or tracing what an address did recently. Returns an array of {hash, lt (string), unix_time, in_value_gram, in_from, out_messages, total_fees_gram} — in_value_gram/in_from describe the incoming message (null for outgoing-only transactions). Never-active addresses return an empty array (not an error); an undecodable transaction comes back as {hash, parse_error: true}. No pagination: each call reads from the account's newest transaction — at most the 30 most recent are reachable. History depth: an error like "lt not in db" means this liteserver has already pruned that part of history — only archive endpoints keep the full chain; retry through one (TON_LITESERVERS or a TONNode hosted key) for deep history.

Parse, validate and convert a TON address between all its formats — purely local, no network access. Use when: normalizing user input, comparing addresses that look different but may be the same account, or converting to the raw form that indexers and APIs expect. Accepts friendly (EQ…/UQ…, with or without URL-safe characters) and raw (workchain:hex) forms. Returns: raw, friendly_bounceable (EQ…), friendly_non_bounceable (UQ…), workchain and flags of the given input. Background: EQ… and UQ… encode the SAME account — EQ (bounceable) is conventional for contracts, UQ (non-bounceable) for user wallets; two addresses are equal if their raw forms match.

Execute a read-only get-method (no gas, no state change) on a smart contract: seqno, get_jetton_data, get_sale_data, get_collection_data and anything else the contract exposes. Use when: reading typed on-chain data from a specific contract. The contract must be active — check with get_account_state first if unsure. Args: only integer arguments are supported here (decimal strings); methods that need an address/slice argument have dedicated tools — e.g. use get_jetton_balance instead of calling get_wallet_address manually. Returns: exit_code (0 or 1 = success; 11 usually means the contract has no such method; other values are contract-specific errors) and the result stack — typed items like {type:"int", value} or {type:"cell"|"slice", boc_base64}.
