Arc Blockchain API
Track trades and token launches on Circle's blockchain.
Arc launched on 16 September 2026. Query token prices and DEX volume, follow launchpad tokens, or stream wallet transfers with Bitquery. Arc uses chain ID 5042 and USDC for gas. Use the Trading API for live markets and the EVM API for other chain data.
subscription { Trading { Trades(where: {Pair: {Market: {Network: {is: "Arc"}}}}) { Block { Time } Trader { Address } Side PriceInUsd AmountsInUsd { Quote } Pair { Market { Protocol } Token { Symbol } QuoteToken { Symbol } } } } }
subscription { EVM(network: arc) { Transfers( where: {Transfer: {Currency: {Symbol: {in: ["USDC", "EURC"]}}}} ) { Transfer { Sender Receiver Amount Currency { Symbol } } } } }
Sample rows show the response format. Prices, assets and timings in this demo are illustrative. Use the linked Arc Blockchain API docs to run queries against live data.
What is Circle's Arc blockchain?
Arc is Circle's EVM-compatible Layer 1, built for stablecoin payments and finance. It also has active token markets and launchpads. USDC pays network fees. Bitquery gives you decoded trades, token transfers, balances, contract calls and events through GraphQL and live streams.
Start with the Arc Blockchain API guide. For live trades and recent history, use Trading.Trades with the network filter Arc. For transfers, balances and contract data, use EVM(network: arc).

- 5042 (hex 0x13b2)
- Network filters
- Trading: Arc · EVM: arc

Network reference sources include the ChainList registry entry for chain 5042, which records USDC as its native currency, and against Circle's founding-validator announcement for the launch date and validator cohort.
Arc at a glance: chain ID 5042.
Arc is a standalone EVM Layer 1 built by Circle for stablecoin settlement. USDC is the native currency, so gas is paid in dollars; Malachite BFT consensus finalises blocks in under a second with no reorg window. Do not confuse it with the unrelated chain listed as “ARC” at chain ID 1243.
Launch day brought token launches and active trading alongside USDC flows. Read our Arc launch-day trading research for volume, trader activity and the launchpad rankings from the hours studied.
Get Arc trades and wallet history without building an index.
Arc finalises a block in under a second. Chasing that with eth_getLogs, hand-decoded Uniswap v4 hooks and Curve registry lookups is a full-time infrastructure job. On a chain this young it is also a job you would start from scratch. Bitquery already did it.
Four ways to get Arc data, one schema underneath.
Prototype over GraphQL, ship over WebSocket or Kafka, backfill your warehouse in bulk. Same decoded data on every channel.
Historical + real-time in one endpoint. Browser-ready subscriptions over WebSocket.
Browser-ready live streams over a single socket, built for tickers, alerting and settlement dashboards.
The lowest-latency Arc stream, with guaranteed delivery for production pipelines. Protobuf or JSON topics.
Full-history datasets delivered to S3, Snowflake, BigQuery or Azure.
Which DEXs and protocols Bitquery decodes on Arc.
Launch-day checks found Uniswap v4, v3 and v2 markets. Filter by protocol in Trading.Trades to inspect each market. Use contract calls and events to study launches or protocols beyond the trade feed.
Where Arc blockchain data comes from, and what each source can answer.
Choose a source for the task. An explorer helps you inspect a single transaction. An indexed API can return trades across wallets or tokens and feed them into your app. Features vary by provider; the table lists common uses and limits.
Coverage on a chain this new moves week by week, so verify against your own queries rather than any summary, including this one. The Arc docs list every field we return.
Every Arc blockchain dataset, one API key.
Query recent trades with Trading and other chain data with EVM. The Arc guides below include filters and stream examples. Historical access and Kafka delivery depend on your plan.

Each one is a filter on the same indexed data. Subscribe over WebSocket or Kafka for bots and alerting, or query GraphQL for dashboards.
Follow large transfers, block by block
Track large token transfers, then filter by contract to follow USDC or EURC. Use sender and receiver addresses to build wallet alerts and treasury dashboards.
Transfer subscriptions →subscription { EVM(network: arc) { Transfers( where: {Transfer: {Amount: {gt: "1000000"}}} ) { Transfer { Sender Receiver Amount Currency { Symbol } } Block { Time } } } }
Track Arc token trades as they happen
Follow prices, trade sizes and trader addresses with Trading.Trades. Add a token or pool filter to focus on one market. Use Trading.Tokens or Trading.Pairs for price candles.
Arc trades, prices and candles →subscription { Trading { Trades(where: {Pair: {Market: {Network: {is: "Arc"}}}}) { Block { Time } Trader { Address } Side PriceInUsd AmountsInUsd { Quote } Pair { Market { Protocol } Token { Symbol } QuoteToken { Symbol } } } } }
A wallet's whole Arc position in one call
Native USDC, every token, current balances and the history behind them. The backbone of treasury dashboards, portfolio trackers and the reconciliation nobody wants to build twice.
Balance & portfolio APIs →query { EVM(network: arc) { Balances( where: {Balance: {Address: {is: "0xada5bb90d0de0bd1b6f3938708f49295a8d1f7cb"}}} ) { Currency { Symbol Native } Balance { Amount } } } }
Catch new pools and token deployments first
Stream pool initializations and new token contracts the block they happen. Seed liquidity, update your token list automatically, or just be the first to know what has deployed on a chain whose history starts at block zero.
Events & contract APIs →subscription { EVM(network: arc) { Events( where: {Log: {Signature: {Name: {is: "Initialize"}}}} ) { Log { Signature { Name } } Transaction { Hash } Block { Number Time } } } }
