# Choose your first Portal query

> Choose a runnable Portal query for EVM, Solana, and other data types.

Each dataset expects a chain-specific request format. Choose a starting point
for the data you want to query:

<CardGroup cols={2}>
  <Card title="EVM quickstart" icon="ethereum" href="/en/portal/evm/quickstart">
    Query Ethereum blocks, then filter transactions and event logs.
  </Card>

  <Card title="Solana quickstart" icon="bolt" href="/en/portal/solana/quickstart">
    Query Solana blocks, then filter transactions and instructions.
  </Card>

  <Card title="Bitcoin example" icon="bitcoin" href="/en/portal/bitcoin/examples/query-transactions">
    Run an interactive query for Bitcoin transactions.
  </Card>

  <Card title="Hyperliquid example" icon="chart-line" href="/en/portal/hyperliquid/examples/query-btc-fills">
    Run an interactive query for BTC perpetual fills.
  </Card>

  <Card title="Tron quickstart" icon="bolt" href="/en/data/tron/tron-mainnet#quick-start">
    Stream TRC-20 transfer logs from Tron mainnet.
  </Card>

  <Card title="Substrate quickstart" icon="link" href="/en/data/substrate/polkadot#quick-start">
    Stream Polkadot blocks and events.
  </Card>
</CardGroup>

The EVM and Solana tutorials include `curl` and TypeScript requests. The
Bitcoin and Hyperliquid pages provide interactive queries. The Tron and
Substrate pages provide copyable `curl` requests. Each destination owns its
request fields, filters, and response examples.

If you want the shared request model before a tutorial, start with the [Portal
API introduction](/en/portal/introduction/portal-api).
