Uniswap API on Elysium: v2, v3 and v4 Trades, Pools and Streams

Uniswap runs v2, v3 and v4 contracts on Elysium (chain ID 99901). Bitquery decodes swaps on all three and returns them through GraphQL queries and WebSocket subscriptions. Every query below is limited to Uniswap's own contracts, so trades on other DEXs that reuse the Uniswap code are left out.

Trades on every Elysium DEX together are on the Elysium DEX Trades page. Uniswap on other chains has its own pages, for example Ethereum Uniswap API.

API Key Required

To query or stream data outside the Bitquery IDE, you need an API access token: How to generate Bitquery API token ➤

Uniswap contracts on Elysium

The addresses come from Uniswap's deployment file for chain 99901 (deployments/99901.md in the Uniswap/contracts repository on GitHub), read on 14 November 2026. The Elysium explorer shows verified source for the factory and PoolManager contracts.

Version	Contract	Address	Bitquery filter
v2	UniswapV2Factory	0xbbbcc62853a5fa27b93d6bab3e6f7ce841e25df2	Trade.Dex.OwnerAddress
v3	UniswapV3Factory	0x1707327f626496a7b5b3872e7e4d2879df7d7a9f	Trade.Dex.OwnerAddress
v4	PoolManager	0xe2e105d3f7209a9da11f83ccf3e7398a753823f1	Trade.Dex.SmartContract, or Pair.Market.Program in the Trading cubes
v4	PositionManager	0x1d1c51b9d07fd27d36412a2b66cc23d19eb3e518	Transaction.To on pool creation

Two facts shape the numbers:

• Several DEXs share the protocol name. Bitquery labels every Uniswap v3 style pool as uniswap_v3, including pools of Aero and Ramses V3. The factory address in Trade.Dex.OwnerAddress separates them.
• Launchpads build on the v4 PoolManager. Montra, Ascend and other launchpads create their token pools on Uniswap's PoolManager with their own hooks, so v4 figures include those tokens. See Elysium Launchpads.

Uniswap volume by version

Counts trades, USD volume, traders and pool contracts for Uniswap v2, v3 and v4 in one request. From the first block in the API (13 November 2026, 22:48 UTC) to 14 November 2026, 05:53 UTC, it returned 45,741 trades and $6.64M on v4, 269 trades on v2 and 254 trades on v3.

{
  EVM(network: elysium) {
    DEXTrades(
      where: {
        any: [
          {Trade: {Dex: {OwnerAddress: {in: ["0xbbbcc62853a5fa27b93d6bab3e6f7ce841e25df2", "0x1707327f626496a7b5b3872e7e4d2879df7d7a9f"]}}}}
          {Trade: {Dex: {SmartContract: {is: "0xe2e105d3f7209a9da11f83ccf3e7398a753823f1"}}}}
        ]
      }
    ) {
      Trade { Dex { ProtocolName } }
      trades: count
      volumeUsd: sum(of: Trade_Buy_AmountInUSD)
      traders: uniq(of: Transaction_From)
      pools: uniq(of: Trade_Dex_SmartContract)
    }
  }
}

All v4 pools live inside the PoolManager contract, so pools is 1 for v4.

Latest Uniswap v4 trades

The Trading cubes return each swap with the trader, the side, both tokens and USD values. Pair.Market.Program holds the PoolManager address.

{
  Trading {
    Trades(
      where: {Pair: {Market: {NetworkBid: {is: "bid:elysium"}, Program: {is: "0xe2e105d3f7209a9da11f83ccf3e7398a753823f1"}}}}
      orderBy: {descending: Block_Time}
      limit: {count: 20}
    ) {
      Block { Time }
      TransactionHeader { Hash }
      Trader { Address }
      Side
      Pair {
        Market { Protocol Program }
        Token { Symbol Address }
        QuoteToken { Symbol Address }
      }
      Amounts { Base Quote }
      AmountsInUsd { Base }
      Price
    }
  }
}

Native HYPE has an empty Address in the Trading cubes.

Top Uniswap v4 pairs by volume

Ranks token pairs on the PoolManager by USD volume in the last 24 hours, with trade and trader counts. On 14 November 2026 the top pair was HYPE against USDC.

Uniswap v2 and v3 trades by factory

Trade.Dex.OwnerAddress is the factory that created the pool. This query returns the latest swaps in pools of Uniswap's v2 and v3 factories, with both tokens and USD amounts.

{
  EVM(network: elysium) {
    DEXTrades(
      where: {Trade: {Dex: {OwnerAddress: {in: ["0xbbbcc62853a5fa27b93d6bab3e6f7ce841e25df2", "0x1707327f626496a7b5b3872e7e4d2879df7d7a9f"]}}}}
      orderBy: {descending: Block_Time}
      limit: {count: 20}
    ) {
      Block { Time }
      Transaction { Hash From }
      Trade {
        Dex { ProtocolName OwnerAddress SmartContract }
        Buy { Amount AmountInUSD PriceInUSD Currency { Symbol SmartContract } }
        Sell { Amount AmountInUSD Currency { Symbol SmartContract } }
      }
    }
  }
}

Trade.Dex.SmartContract is the pool contract for v2 and v3.

New Uniswap v3 pools

The v3 factory emits PoolCreated for each new pool. The arguments carry both tokens, the tick spacing and the pool address.

{
  EVM(network: elysium) {
    Events(
      where: {Log: {SmartContract: {is: "0x1707327f626496a7b5b3872e7e4d2879df7d7a9f"}, Signature: {Name: {is: "PoolCreated"}}}}
      orderBy: {descending: Block_Time}
      limit: {count: 10}
    ) {
      Block { Time }
      Transaction { Hash From }
      Arguments {
        Name
        Value {
          ... on EVM_ABI_Address_Value_Arg { address }
          ... on EVM_ABI_BigInt_Value_Arg { bigInteger }
          ... on EVM_ABI_Integer_Value_Arg { integer }
        }
      }
    }
  }
}

New v4 pools come from the PoolManager's Initialize event. That query is on the Elysium Liquidity Pools page.

Stream Uniswap v4 trades over WebSocket

The subscription pushes each new swap on the PoolManager as Bitquery indexes it. Connection steps are in WebSocket subscriptions.

subscription {
  Trading {
    Trades(
      where: {Pair: {Market: {NetworkBid: {is: "bid:elysium"}, Program: {is: "0xe2e105d3f7209a9da11f83ccf3e7398a753823f1"}}}}
    ) {
      Block { Time }
      TransactionHeader { Hash }
      Trader { Address }
      Side
      Pair {
        Token { Symbol Address }
        QuoteToken { Symbol Address }
      }
      Amounts { Base Quote }
      AmountsInUsd { Base }
      Price
    }
  }
}

The same swaps are in the Kafka topic elysium.dextrades.proto: Kafka Streams for Elysium.

FAQ

Which Uniswap versions run on Elysium?

Uniswap v2, v3 and v4. Uniswap's deployment file for chain 99901 lists a factory for v2 and v3 and a PoolManager for v4. Most trades are on v4: 45,741 of 46,264 Uniswap trades in the API on 14 November 2026.

What is the Uniswap v4 PoolManager address on Elysium?

0xe2e105d3f7209a9da11f83ccf3e7398a753823f1. It differs from the PoolManager address on other chains, so do not reuse an address from Ethereum or Base.

Why does a uniswap_v3 filter return Aero and Ramses trades?

ProtocolName describes the pool design. Aero and Ramses V3 pools follow the Uniswap v3 design, so they carry the same label. Filter Trade.Dex.OwnerAddress by the Uniswap v3 factory to keep Uniswap's own pools.

Are launchpad tokens included in Uniswap v4 data?

Yes. Launchpads such as Montra and Ascend create pools on Uniswap's PoolManager. To separate them, filter the Initialize event by hook address as shown on the Elysium Launchpads page.
