# Blocks & Transactions

> Query examples for Blocks, Transactions, Events, Calls, and other infrastructure Cubes

## Overview

This page covers query examples for blockchain infrastructure Cubes — the foundational data about blocks, transactions, smart contract events, and internal traces.

***

## Blocks

### Latest Blocks (Solana)

```graphql theme={null}
query {
  Solana {
    Blocks(limit: {count: 10}, orderBy: {descending: Block_Time}) {
      Block {
        Time
        Slot
        Height
        Hash
        ParentSlot
        TxCount
      }
    }
  }
}
```

### Latest Blocks (Ethereum)

```graphql theme={null}
query {
  EVM(network: eth) {
    Blocks(limit: {count: 10}, orderBy: {descending: Block_Time}) {
      Block {
        Time
        Number
        Hash
        GasUsed
        GasLimit
        BaseFee
        TxCount
        Coinbase
      }
    }
  }
}
```

## Transactions

### Recent Transactions by Address (Solana)

```graphql theme={null}
query {
  Solana {
    Transactions(
      signer: {is: "WALLET_ADDRESS"}
      limit: {count: 20}
      orderBy: {descending: Block_Time}
    ) {
      Block { Time Slot }
      Transaction {
        Signature
        Fee
        FeePayer
        Result { Success }
      }
    }
  }
}
```

### Recent Transactions by Address (EVM)

```graphql theme={null}
query {
  EVM(network: eth) {
    Transactions(
      fromAddress: {is: "0xWALLET_ADDRESS"}
      limit: {count: 20}
      orderBy: {descending: Block_Time}
    ) {
      Block { Time Number }
      Transaction {
        Hash
        From
        To
        Value
        Gas
        GasPrice
      }
    }
  }
}
```

## Events (EVM Only)

### Filter Events by Contract and Topic

```graphql theme={null}
query {
  EVM(network: eth) {
    Events(
      contractAddress: {is: "0xCONTRACT_ADDRESS"}
      limit: {count: 20}
      orderBy: {descending: Block_Time}
    ) {
      Block { Time Number }
      Transaction { Hash }
      Log {
        SmartContract
        Index
        Signature { Name Signature }
        Data
      }
    }
  }
}
```

### Filter by Event Signature (Topic0)

```graphql theme={null}
query {
  EVM(network: eth) {
    Events(
      topic0: {is: "0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef"}
      limit: {count: 10}
      orderBy: {descending: Block_Time}
    ) {
      Block { Time }
      Transaction { Hash }
      Log { SmartContract Index Data }
    }
  }
}
```

## Calls / Traces (EVM Only)

### Internal Calls to a Contract

```graphql theme={null}
query {
  EVM(network: eth) {
    Calls(
      toAddress: {is: "0xCONTRACT_ADDRESS"}
      limit: {count: 20}
      orderBy: {descending: Block_Time}
    ) {
      Block { Time Number }
      Transaction { Hash }
      Call {
        From
        To
        Opcode
        Value
        Gas
        GasUsed
        Signature { Name }
      }
    }
  }
}
```

## Instructions (Solana Only)

### Recent Instructions for a Program

```graphql theme={null}
query {
  Solana {
    Instructions(
      programId: {is: "PROGRAM_ADDRESS"}
      limit: {count: 20}
      orderBy: {descending: Block_Time}
    ) {
      Block { Time Slot }
      Transaction { Signature }
      Instruction {
        Index
        Depth
        Program { Address Name Method }
        Accounts
