# List transactions

POST https://your-endpoint.example.com/transactions
Content-Type: application/json

Recent history for that asset, newest first, capped by the service's page size (10 by default).

Every chain is normalised to the same row shape. `type` is `send` or `receive` relative to this user, `amount` is denominated in the asset, and `fee` is denominated in the chain's **native** currency.

Sources: Bitcoin Core `listtransactions`, Etherscan v2 (EVM), TronGrid (TRON), RPC signatures (Solana). An empty history is `[]`, not an error.
