CRONOS API · GraphQL · Kafka · gRPC · Cloud export

The Cronos data API wired for Crypto.com scale.

You shouldn't have to run a Cronos node, babysit an archive node or stitch together raw JSON-RPC just to answer a simple question. On Enterprise, we've already indexed Uniswap trades, token transfers, contract calls, events and the mempool are one query — or one live stream — away.

Forget the RPC

JSON-RPC was never meant to answer the questions you actually have.

Ask "what did this wallet ever do?" and raw Cronos hands you an archive node, a pile of ABIs to decode by hand and thousands of chained eth_getLogscalls. We've already done that work, so you can skip straight to the answer.

What you're doing
Raw Cronos JSON-RPC
Bitquery Cronos API

You decode every event log
Decoded for every protocol
ERC-20, 721 & 1155 in one place
Three ABIs to parse yourself
One unified token schema
Mempool & pending transactions
Run your own node & filters
Streamed, sub-second

Infrastructure to run
Cronos, archive, reorg handling
None — fully managed
02
Delivery channels

Four ways to get Cronos data — one schema underneath.

Write your query once in GraphQL and the same fields come back over GraphQL streams, Kafka, gRPC or a bulk cloud export. Nothing to re-model and no second pipeline to maintain — just pick the channel that matches how fast and how much you need.

03
DEX & protocol coverage

Every major Cronos venue, decoded into one feed.

One DEXTrades query covers 100+ Cronos DEXs. Filter by token, pair, pool, wallet or protocol, then roll it up however you need — OHLCV candles, liquidity events, slippage, pool reserves, top traders or volume.

Cronos datasets

Every Cronos dataset, one GraphQL endpoint.

From ERC-20 transfers to the mempool, it's all behind a single endpoint — no node, no archive sync, no indexer to build. Every dataset is available as complete history on Enterprise and streams live over WebSocket or gRPC (fixed-cost Kafka on Enterprise) whenever you need it real time.

Build it this weekend

The Cronos products people actually ship on us.

Each of these is just a filter on the same indexed data — subscribe over WebSocket or gRPC on self-service (fixed-cost Kafka on Enterprise) when you're building a bot, or hit GraphQL when you're building a dashboard.

Catch new VVS Finance pools first

Get pool-creation and hook events the second they land, filtered by token pair or fee tier. Be early to every new market without watching the chain yourself.

Wallet PnL & portfolio

Pull a wallet's entire transfer and trade history with historical USD prices already attached, and work out realized PnL across every DEX it has touched.

What teams say about our Cronos data

"We did a thorough search of the market for the best onchain data. Bitquery came out on top — and now powers all live prices across Nansen. We don't think of them as a vendor. They're a partner."

FAQ

Cronos data questions, answered.

How can I get Cronos blockchain data with Bitquery?
You get both historical and real-time Cronos data through our GraphQL APIs, WebSocket subscriptions, Kafka streams and cloud warehouses (AWS, Snowflake, BigQuery). This chain is available on Enterprise — talk to sales for a committed plan, then start pulling blocks, transactions, transfers, DEX trades, NFT events, contract calls and ENS records from a single endpoint right away.
How do I query Uniswap, SushiSwap and other Cronos DEX trades?
One DEXTrades query covers Uniswap V2/V3/V4, SushiSwap, Curve, Balancer, 1inch, PancakeSwap and 50+ other DEXs. Filter by token address, pair, time range or trader wallet, then aggregate into OHLCV candles, top traders or volume per pool — whatever your chart or report needs.
Can I stream Cronos data in real-time — mempool, new blocks, transfers?
Yes — over Kafka, WebSocket subscriptions and gRPC, all with sub-second latency. You can stream pending transactions (the mempool), new blocks, token transfers, DEX trades and contract events, which is exactly what you want for trading bots, alerts, MEV monitoring and live analytics.
Does Bitquery support ERC-20, ERC-721 and ERC-1155 tokens?
Yes. Every ERC-20, ERC-721 and ERC-1155 token on Cronos is indexed with full transfer history, holder counts, balances and metadata — and it all sits behind the same GraphQL schema, so you don't juggle three different standards.
How do I get Cronos wallet balances, transactions and PnL?
Point the Transfers, Trades and Balancesqueries at a wallet address and you'll get its full transaction history, current and historical token balances, ENS name and trading PnL across every DEX it has used.
Does Bitquery support smart-contract calls and decoded event logs?
Yes. We decode and index every smart-contract call and event log on Cronos straight from the contract's ABI. You can query function calls (swap, mint, transferFrom) and emitted events (Transfer, Approval, Sync) by contract address, function name or event signature — no manual decoding on your side.
