# transactionsByPublicKey

**Type:** GraphQL queries

**Description:**
Retrieve a paginated list of transactions associated with a specific public key.

This query returns all transactions that involve accounts controlled by the given `publicKey`.
Because a single public key can control multiple accounts — including accounts on different chains
or created by contracts — this query is a convenient way to fetch all related transactions
without needing to know each account name individually.

It is commonly used by wallets, explorers, and analytics tools to display a user’s complete
on-chain activity, track transactions linked to a particular key, or audit key usage across the network.

## Arguments
- publicKey (String): The public key to filter transactions by.
Example: `"abcdef1234567890..."`.
- after (String): Cursor to start paginating **after** a specific result.
Used for forward pagination.
- before (String): Cursor to start paginating **before** a specific result.
Used for backward pagination.
- first (Int): Maximum number of transactions to return when paginating forward.
- last (Int): Maximum number of transactions to return when paginating backward.
