Accounts

Get account info

To get account info including BOC, data and code, use the following GraphQL query:

query {
  blockchain{
   account(address:"0:653b9a6452c7a982c6dc92b2da9eba832ade1c467699ebb3b43dca6d77b780dd"){
    info{
      address
      acc_type
      balance
      last_paid
      last_trans_lt
      boc
      data
      code
      library
      data_hash
      code_hash
      library_hash
    }
  }
  }
}

Result:

fields:

  • address is full account address that consists of workchainID:address

  • acc_type

    • 0 – uninit (Account has balance but no code)

    • 1 – active (Account has balance and code)

    • 2 – frozen(Account has been frozen for some reasons)

    • 3 - nonExist (Account was deleted)

  • last_paid - unixtime of the most recent storage payment (happens each transaction execution)

  • balance - tokens on account (Note: to deploy smart contract code you need to have non-zero balance)

  • last_trans_lt - logical time of last account transaction

  • boc - Bag of cells with the account struct encoded as base64 (contains code, data, library and other header information).

  • data - bag of cells with the account's data

  • code - bag of cells with the account's code

  • library - If present, contains library code used in smart-contract.

  • data_hash - hash of account data

  • code_hash - hash of account code

  • library_hash - library field hash

Filter accounts

If you need to filter accounts by some condition and paginate them, use accounts collection.

Use id(account address) as cursor for pagination.

Paginate accounts having same code_hash:

query{
  accounts(
    filter:{
      code_hash:{
        eq:"80d6c47c4a25543c9b397b71716f3fae1e2c5d247174c52e2c19bd896442b105"
      }
      id:{
        gt:"0:001a338e4af5fe33307c2b0d04de453513019942748eb2b290ca3db0adfe8343"
      }
    }
    orderBy:[
      {
        path:"id",
        direction:ASC
      }
    ]
  ){
    id
    balance(format:DEC)
    last_paid
  }
}

Paginate accounts having same code_hash, updated after timestamp

query{
  accounts(
    filter:{
      workchain_id:{
        eq:0
      },
      code_hash:{
        eq:"80d6c47c4a25543c9b397b71716f3fae1e2c5d247174c52e2c19bd896442b105"
      }
      last_paid:{
        ge:1687023485
      }
      id:{
        gt:"0:001a338e4af5fe33307c2b0d04de453513019942748eb2b290ca3db0adfe8343"
      }
    }
    orderBy:[
      {path:"last_paid", direction:ASC}      
      {path:"id", direction:ASC}
    ]
  ){
    id
    balance(format:DEC)
    last_paid
  }
}

Get a list of accounts

You can enumerate a list of account addresses to get their balances and other metadata.

You can not get the list of BOCs of accounts. Retrieve each account's BOC individually with this query.

query{
  accounts(
    filter:{
    	id:{
        in:[
          "0:001b3abc5f9e906990c2eee7a1664be20b1b47fdf5c140331e6003786735f453",

        ]
      }
  	}
  ){
    id
    balance(format:DEC)
    last_paid
    last_trans_lt
  }
}

Get transactions within timestamp range

Use-cases

  • Paginate transactions to get both transactions and messages of account within the required timestamp range

  • Collect account transactions with detailed fees information

  • Collect account balance history by pre-processing balance_delta changes on your side

  • Query new account transactions to trigger some logic on your side

  • Optionally filter transactions by Aborted type or balance_delta value

  • Pull transactions for a period if your websocket subscription failed (use lastTransaction.chain_order field as after cursor ;-) )

Filter parameters

You can filter account transactions by these parameters:

aborted: Boolean
min_balance_delta: String
max_balance_delta: String

Pagination parameters

Use cursor, {first, after} or {last, before} filters for pagination.

We followed GraphQL best practices and implemented Relay Cursor Connections Specification for pagination for all list types. You can read more here https://relay.dev/graphql/connections.htm

Let's paginate some account transactions from the very first one:

query {
  blockchain{
   account(address:"0:653b9a6452c7a982c6dc92b2da9eba832ade1c467699ebb3b43dca6d77b780dd"){
    transactions
    {
      edges{
        node{
          hash
          in_message{
            hash
            value
            body
          }
          out_messages{
            hash
            value
            body
          }
          
        }
      }
      pageInfo{
        endCursor
        hasNextPage
      }
    }
  }
  }
}

Result

{
  "data": {
    "blockchain": {
      "account": {
        "transactions": {
          "edges": [
            {
              "node": {
                "hash": "c8153cd353bf90c7c1214d8c1a50a30ea6d0d900f0f6c7242d1434644c1e49fb",
                "hash": "c8153cd353bf90c7c1214d8c1a50a30ea6d0d900f0f6c7242d1434644c1e49fb",
                "in_message": {
                  "hash": "c2b064872a2ce6db65ca724a03d1be5de37abe784c658ef4d5998249b9643144",
                  "value": "0x229bd2a5eb3ef4",
                  "body": null
                },
                "out_messages": []
              }
            },
            ...
          ],
          "pageInfo": {
            "endCursor": "5286af50052a33e50104",
            "hasNextPage": true
          }
        }
      }
    }
  }
}

Use endCursor field for further pagination and hasNextPage for identifying if more records exist.

Get messages within timestamp range

Use-cases:

  • get transfers that some account sent or received

  • get account's events

  • get external calls of an account

  • get transfers between an account and some counterparty account

  • get account events to an external address

  • optionally filter messages by value amount

  • Pull messages for a period if your websocket subscription failed (use Message.chain_order field as after cursor ;-) )

In all these cases you need to paginate account messages with some filters applied. Lets see how to do it.

Filter parameters

You can filter messages by these parameters:

master_seq_no_range: {start: Timestamp, end: Timestamp} # Time interval for pagination
counterparties: [String!]
msg_type: [BlockchainMessageTypeFilterEnum!]
min_value: String

enum BlockchainMessageTypeFilterEnum {
    ExtIn #    External inbound
    ExtOut #    External outbound
    IntIn #    Internal inbound
    IntOut #    Internal outbound
}

Pagination parameters

Use cursor, {first, after} or {last, before} filters for pagination.

We followed GraphQL best practices and implemented Relay Cursor Connections Specification for pagination for all list types. You can read more here https://relay.dev/graphql/connections.htm

Account transfers

Lets get first 2 transfers some account received or sent. So we need to get incoming and outcoming internal messages. We separated internal message type into 2 types: IntIn and IntOut for search convenience. This way it is possible also to get only deposits, and only withdrawals.

query{
  blockchain{
    account(address:"-1:99392dea1c5035feddb1bb3db9e71138d82868f7460c6da3dca26f0520798ebd"){
      messages(msg_type:[IntIn, IntOut],first:2){
        edges{
          node{
            src
            dst
            id
            hash
            value(format:DEC)
            msg_type
            created_at_string
          }
          cursor
        }
        pageInfo{
          hasNextPage
        }
      }
    }
  }
}

Result. We see that the next page exists, we can continue pagination.

          }
        }
      }
    }
  }
}

Account events

To get account events, we need to get Account's external outbound message. Their type is ExtOut. Body field contains ABI-encoded information with Event data. You can parse it with SDK function abi.decode_message_body.

query{
  blockchain{
    account(address:"0:454abb3c7db044603a9fb0802d3c6507b08d6b04855baa9a60802d9ecd34edad"){
      messages(msg_type:[ExtOut],first:2){
        edges{
          node{
            hash
            body
            created_at_string
          }
          cursor
        }
        pageInfo{
          hasNextPage

          }
        }

  }
}

Account external calls

If you want to collect external calls of an account, filter by msg_type = ExtIn. Body field contains ABI-encoded information with Event data. You can parse it with SDK function abi.decode_message_body. Lets get the last external call:

query{
  blockchain{
    account(address:"0:3d10c4d6dfc5d3cf6f8ac3d7468b792b91385c087da8f59669569493c7c0e28e"){
      messages(msg_type:[ExtIn],last:1){
        edges{
          node{
            hash
            body
            created_at_string
          }
          cursor
        }
        pageInfo{
          hasPreviousPage
        }
      }
    }
  }

Transfers between 2 accounts

In this example we retrieve last 30 messages between elector contract and some validator wallet with value more than some number:

query{
  blockchain{
    account(address:"-1:3333333333333333333333333333333333333333333333333333333333333333"){
      messages(last:30, counterparties:["-1:99392dea1c5035feddb1bb3db9e71138d82868f7460c6da3dca26f0520798ebd"],
       min_value:"58579566000" ){
        edges{
          node{
            src
            dst
            id
            hash
            value(format:DEC)
            msg_type
            created_at_string
          }
          cursor
        }
        pageInfo{
          hasPreviousPage
        }
      }
    }
  }
