Arc Mainnet Transfers API & Streams

Query and stream token transfers on Arc mainnet with Bitquery GraphQL. This is the shared EVM Transfers cube scoped to network: arc, so a query written for Ethereum or Base runs here by changing the network name.

Arc's native gas token is USDC, and the chain carries an ERC-20 USDC interface, EURC, USYC and user-issued assets. Every query on this page was executed against the production endpoint before publishing. Change query to subscription on any of them to stream the same rows over WebSocket.

Availability checked 16 September 2026

Transfer.AmountInUSD returned populated values. Only the realtime path answered, so leave the dataset argument out until archive and combined are enabled.

API Key Required

To query or stream data outside the Bitquery IDE, you need an API access token.

How USDC appears in Transfers

USDC exists in three forms on Arc mainnet. Check which one a row is before you sum or rank anything.

Currency	`SmartContract`	`Native`	Decimals	What it is
USDC (native)	`0x`	`true`	18	The gas token and native value-transfer form. Read transaction fee fields for gas fees.
USDC (ERC-20)	`0x3600000000000000000000000000000000000000`	`false`	6	The ERC-20 interface most contracts and wallets call. Symbol `USDC`, name `USDC`.
System ledger	`0xfffffffffffffffffffffffffffffffffffffffe`	`false`	0	A system address that emits a raw `Transfer` event mirroring native USDC movements as 18-decimal integers with no symbol. Exclude it from token rankings.

Official tokens on Arc mainnet:

Token	Address	Decimals
EURC	`0xbef5f6d51cb62b58e6a8f77868681825c6fe21c1`	6
USYC	`0x8a5d989bbb96929f689b0200f435f53da42bf490`	6

Stream real-time transfers

Native USDC transfers

▶️ Run in IDE

Currency: {Native: true} selects value transfers of the gas token. The floor of 100 USDC keeps dust and fee movements out.

{
  EVM(network: arc) {
    Transfers(
      limit: {count: 20}
      orderBy: {descending: Block_Time}
      where: {
        Transfer: {
          Currency: {Native: true}
          Amount: {gt: "100"}
        }
      }
    ) {
      Block {
        Time
      }
      Transaction {
        Hash
      }
      Transfer {
        Amount
        Sender
        Receiver
        Currency {
          Symbol
          Native
        }
      }
    }
  }
}

Transfers of a token

▶️ Run in IDE

Filter on the token contract. This example reads the ERC-20 USDC interface; swap in EURC or any test token.

{
  EVM(network: arc) {
    Transfers(
      limit: {count: 20}
      orderBy: {descending: Block_Time}
      where: {
        Transfer: {
          Currency: {SmartContract: {is: "0x3600000000000000000000000000000000000000"}}
        }
      }
    ) {
      Block {
        Time
      }
      Transaction {
        Hash
      }
      Transfer {
        Amount
        Sender
        Receiver
        Currency {
          Symbol
          Decimals
        }
      }
    }
  }
}

Transfers of an address

▶️ Run in IDE

Incoming and outgoing transfers in one list. Replace the address with any wallet or contract.

{
  EVM(network: arc) {
    Transfers(
      limit: {count: 20}
      orderBy: {descending: Block_Time}
      where: {
        any: [
          {Transfer: {Sender: {is: "0xada5bb90d0de0bd1b6f3938708f49295a8d1f7cb"}}}
          {Transfer: {Receiver: {is: "0xada5bb90d0de0bd1b6f3938708f49295a8d1f7cb"}}}
        ]
      }
    ) {
      Block {
        Time
      }
      Transaction {
        Hash
      }
      Transfer {
        Amount
        Sender
        Receiver
        Currency {
          Symbol
          SmartContract
          Native
        }
      }
    }
  }
}

Sent and received totals per token

▶️ Run in IDE

Two aliased selections give the outbound and inbound sums per currency for a wallet.

{
  EVM(network: arc) {
    sent: Transfers(
      where: {Transfer: {Sender: {is: "0xada5bb90d0de0bd1b6f3938708f49295a8d1f7cb"}}}
      orderBy: {descendingByField: "amount"}
      limit: {count: 10}
    ) {
      Transfer {
        Currency {
          Symbol
          SmartContract
        }
      }
      amount: sum(of: Transfer_Amount)
      count
    }
    received: Transfers(
      where: {Transfer: {Receiver: {is: "0xada5bb90d0de0bd1b6f3938708f49295a8d1f7cb"}}}
      orderBy: {descendingByField: "amount"}

        }
      }
      amount: sum(of: Transfer_Amount)
      count
    }
  }
}

Transfers between two addresses

▶️ Run in IDE

Flows from one address to another, in either direction. Useful for tracing a faucet, a bridge or a counterparty.

{
  EVM(network: arc) {
    Transfers(
      limit: {count: 20}
      orderBy: {descending: Block_Time}
      where: {
        any: [
          {
            Transfer: {
              Sender: {is: "0xada5bb90d0de0bd1b6f3938708f49295a8d1f7cb"}
              Receiver: {is: "0xb92fe925dc43a0ecde6c8b1a2709c170ec4fff4f"}
            }
          }
          {
            Transfer: {
              Sender: {is: "0xb92fe925dc43a0ecde6c8b1a2709c170ec4fff4f"}
              Receiver: {is: "0xada5bb90d0de0bd1b6f3938708f49295a8d1f7cb"}
            }
          }
        ]
      }
    ) {
      Block {
        Time
      }
      Transaction {

          Native
        }
      }
    }
  }
}

Large transfers

▶️ Run in IDE

This catches ERC-20 USDC moves above 10,000 and returns both token and USD amounts.

{
  EVM(network: arc) {
    Transfers(
      limit: {count: 20}
      orderBy: {descending: Transfer_Amount}
      where: {
        Block: {Time: {since_relative: {hours_ago: 24}}}
        Transfer: {
          Currency: {SmartContract: {is: "0x3600000000000000000000000000000000000000"}}
          Amount: {gt: "10000"}
        }
      }
    ) {
      Block {
        Time
      }
      Transaction {
        Hash
      }
      Transfer {
        Amount
        AmountInUSD
        Sender
        Receiver
        Currency {
          Symbol
        }
      }
    }
  }
}

Most transferred tokens

▶️ Run in IDE

Tokens ranked by transfer count over 24 hours, with distinct senders and receivers. The system ledger address is excluded.

{
  EVM(network: arc) {
    Transfers(
      limit: {count: 20}
      orderBy: {descendingByField: "count"}
      where: {
        Block: {Time: {since_relative: {hours_ago: 24}}}
        Transfer: {
          Currency: {SmartContract: {not: "0xfffffffffffffffffffffffffffffffffffffffe"}}
        }
      }
    ) {
      Transfer {
        Currency {
          Symbol
          Name
          SmartContract
          Native
        }
      }
      count
      amount: sum(of: Transfer_Amount)
      senders: uniq(of: Transfer_Sender)
      receivers: uniq(of: Transfer_Receiver)
    }
  }
}

Hourly transfer volume of a token

▶️ Run in IDE

Transfer volume of ERC-20 USDC bucketed by hour, for charts and alerts.

{
  EVM(network: arc) {
    Transfers(
      orderBy: {descendingByField: "Block_Time"}
      limit: {count: 24}
      where: {
        Transfer: {
          Currency: {SmartContract: {is: "0x3600000000000000000000000000000000000000"}}
        }
      }
    ) {
      Block {
        Time(interval: {in: hours, count: 1})
      }
      amount: sum(of: Transfer_Amount)
      count
      senders: uniq(of: Transfer_Sender)
    }
  }
}

FAQ

Does AmountInUSD work? Yes. It returned populated values in the production check on 16 September 2026.

Which USDC address should I filter on? For gas-token value transfers use Currency: {Native: true}. For the ERC-20 interface that wallets and contracts call, use 0x3600000000000000000000000000000000000000. Do not filter on 0xfffffffffffffffffffffffffffffffffffffffe; it is a system ledger that duplicates native movements as raw integers.

Why are native amounts 18 decimals when USDC has 6? The EVM represents the gas token in wei-style 18-decimal units regardless of what the token is called. Bitquery applies those 18 decimals to native rows and the contract's own 6 decimals to ERC-20 rows, so Amount is a whole-token value in both cases.

Should I add native and ERC-20 USDC transfers together? No. Arc's ERC-20 interface acts on the native USDC balance, so the two views can describe linked activity. Choose the form that matches the action you track and guard against double counting.

Can I read history older than the realtime window? Not yet. Only the realtime path answered on 16 September 2026. Check the window with Block { Time(minimum: Block_Time) } and retry archive or combined before using them.

How do I stream transfers for one wallet? Take the transfers of an address query, change query to subscription and drop limit and orderBy.
