Overview

ChainStream GraphQL organizes its 25 Cubes into three Chain Groups. Each group represents a blockchain ecosystem and determines which Cubes are available, how the network parameter works, and what chain-specific fields exist. 
type ChainStream {
  EVM(network: Network!, dataset: Dataset, aggregates: Aggregates) { ... }
  Solana(dataset: Dataset, aggregates: Aggregates) { ... }
  Trading(dataset: Dataset, aggregates: Aggregates) { ... }
}

​
EVM

The EVM group contains Cubes for all EVM-compatible blockchains. It requires a network argument to specify which chain to query.

​
Available Networks

Network IDBlockchain
ethEthereum
bscBNB Chain (BSC)
polygonPolygon

​
Cubes

Shared with Solana: DEXTrades, DEXTradeByTokens, Transfers, BalanceUpdates, DEXPoolEvents, TokenSupplyUpdates, Blocks, Transactions, TransactionBalances, DEXPools, TokenHolders, WalletTokenPnL EVM-only:
  • Events — Smart contract event logs (decoded topics and data)
  • Calls — Internal call traces (CALL, DELEGATECALL, CREATE, etc.)
  • MinerRewards — Block rewards breakdown (static, dynamic, uncle, burned fees)
  • DEXPoolSlippages — Pool price slippage analysis
  • Uncles — Uncle block data (primarily Ethereum PoW historical)
  • PredictionTrades — Prediction market trades (primarily Polygon)
  • PredictionManagements — Prediction market management events (primarily Polygon)
  • PredictionSettlements — Prediction market settlements (primarily Polygon)

​
Example Query

query {
  EVM(network: eth, dataset: combined) {
    DEXTrades(
      limit: {count: 10}
      orderBy: Block_Time_DESC
    ) {
      Block { Time Number }
      Transaction { Hash }
      Trade {
        Buy { Currency { SmartContract Symbol } Amount PriceInUSD }
        Sell { Currency { SmartContract Symbol } Amount }
        Dex { ProtocolName }
      }
    }
  }
}

​
Solana

The Solana group contains Cubes for the Solana blockchain. The network is implicit (sol) — no network argument is needed.

​
Cubes

Shared with EVM: DEXTrades, DEXTradeByTokens, Transfers, BalanceUpdates, DEXPoolEvents, TokenSupplyUpdates, Blocks, Transactions, TransactionBalances, DEXPools, TokenHolders, WalletTokenPnL Solana-only:
  • Instructions — Program instruction data (program address, method, accounts, logs)
  • InstructionBalanceUpdates — Balance changes at instruction level
  • Rewards — Validator and staking rewards
  • DEXOrders — DEX order book events (limit orders, cancellations, fills)

​
Example Query

query {
  Solana(dataset: realtime) {
    DEXTrades(
      limit: {count: 10}
      orderBy: Block_Time_DESC
    ) {
      Block { Time Slot }
      Transaction { Hash }
      Trade {
        Buy { Currency { MintAddress Symbol } Amount PriceInUSD }
        Sell { Currency { MintAddress Symbol } Amount }
        Dex { ProgramAddress ProtocolName }
      }
    }
  }
}

​
Solana-Specific Fields

Solana Cubes use different field names for some dimensions compared to EVM:
ConceptSolanaEVM
Token addressMintAddressSmartContract
Transaction IDSignature / HashHash
Block identifierSlotNumber
Program/ContractProgramAddressSmartContract
Fee payerFeePayerFrom

​
Trading

The Trading group provides cross-chain pre-aggregated trading analytics. It combines data from all supported chains into unified materialized views with a chain dimension for filtering.

​
Cubes

  • Pairs — OHLC candlestick data (open/high/low/close, volume, trade count)
  • Tokens — Per-token trade statistics (volume, buy/sell breakdown, unique traders)

​
Key Differences from EVM/Solana Groups

  1. No network argument — The Trading group combines data across chains. Use the chain dimension within the data to filter by network.
  2. Cross-chain data — A single query can return data for sol, eth, and bsc together.
  3. Pre-aggregated — Data is materialized at minute granularity from the DWM layer.

​
Example: Cross-Chain OHLC

query {
  Trading(aggregates: yes) {
    Pairs(
      where: { Token: { Address: { is: "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v" } } }
      limit: {count: 60}
      orderBy: Block_Time_DESC
    ) {
      Token { Address }
      Market { Network }
      Interval { Time }
      Price { Ohlc { Open High Low Close } }
      Volume { Usd Native }
      Stats { TradeCount BuyCount SellCount }
    }
  }
}

​
Example: Token Trade Stats by Chain

query {
  Trading {
    Tokens(
      where: {
        Token: { Address: { is: "0xdac17f958d2ee523a2206206994597c13d831ec7" } }
        Market: { Network: { is: "eth" } }
      }
      limit: {count: 30}
      orderBy: Block_Time_DESC
    ) {
      Interval { Time }
      Volume { Usd BuyVolumeUSD SellVolumeUSD }
      Stats { TradeCount UniqueBuyers UniqueSellers }
    }
  }
}
