The default configuration for ton full node (https://github.com/ton-blockchain/ton/blob/master/validator/validator.h#L95) is to save state for 1 hour. Block related data is saved for 1 week. Both are moved to archive dir after this period. Archive dir is deleted after 1 year. This configuration can be changed and archive nodes for example will deploy their nodes with much bigger values so users can query state at anytime in history. In order to query an old state (more than 1 hour ago) **you will need to use an archive node**. Using the [TON APIv4](https://github.com/ton-foundation/ton-api-v4), you can query `GET /block/<seqno>/<address>/run/<method>/<args?>` which can be used with `method=get_wallet_data` to query jetton balance. In [Toncenter](https://toncenter.com/api/v2/) for example, it is not possible to query a method from old states. However, you can use `getTransactions` with `archival=true` to get all transactions and calculate the exact amount on each state. Transactions in non archive (default) nodes will be stored for 1 week.

The default configuration for a TON full node ([see source code](https://github.com/ton-blockchain/ton/blob/d11580dfb3b81ea5d00775502737d59c155adfb2/validator/validator.h#L95)) is to save state for 1 hour and block related data for 1 week. Both are moved to the archive dir after this period. Archive dir is deleted after 1 year. This configuration can be changed and archive nodes for example will deploy their nodes with much larger configuration values so users can query state at any time in history. In order to query an old state (more than 1 hour ago) you will need to use an archive node. ### TonHub API v4 https://github.com/ton-foundation/ton-api-v4 ``` GET /block/<seqno>/<address>/run/<method>/<args?> ``` This API can be used with method = `get_wallet_data` to query jetton balance from an old block. It seems that the TonHub endpoint currently supports archive calls but this is not documented as a guaranteed feature. ### TonCenter HTTP API https://toncenter.com/api/v2/ I didn't see in TonCenter API a way to use archive node so it is not probably possible to query very old state. However, you can query the list of transactions which are stored for 1 week to calculate the exact amount on each state update during the last week and work back the solution.
