# alchemy_minedTransactions
> Emits full transaction objects or hashes that are mined on the network based on provided filters and block tags.
> For the complete documentation index, see [llms.txt](/docs/llms.txt).
The `alchemy_minedTransactions` subscription type subscribes to mined transactions via WebSockets, and filters those transactions based on specified `from` and/or `to` addresses. The subscription will return either full transaction objects or just transaction hashes depending on the request. It will also optionally include re-orged or removed transactions if specified.
# Supported Networks
Check the [Chains](https://dashboard.alchemy.com/chains) page for details about product and chain support!
# Parameters
* `addresses` (optional): \[`array of objects`] list of addresses to filter mined transactions for specified by `to` or `from` in the following format: `[{"to": "string", "from": "string"}]`. Limit of 1000 total addresses.
* `includeRemoved` (optional): `boolean` specifier to include transactions that have been removed from the cannonical chain (or [re-orged](/docs/what-is-proof-of-stake#what-is-a-re-org-re-organization)).
* `hashesOnly` (optional): `boolean` default value is `false`, where the response will return a full transaction object (matches the payload of [eth\_getTransactionByHash](/docs/reference/eth-gettransactionbyhash)) . If set to `true`, the payload returned contains only the *hashes* of the transactions that are mined. Prefer `true` unless you need full transaction objects immediately.
Excluding all parameters returns the transaction information for **all transactions** that are mined on chain.
A good starting point is to add address filters and set `hashesOnly` to
`true`, then request full transaction objects only when you need them.
# Returns
Mined transactions are returned once they are mined in the `latest` block. In the future we may add support to specify a given block tag confirmation.
With `hashesOnly` = `true`
* `result`:
* `removed` - `boolean` specifier if the transaction has been removed (re-orged)
* `transaction` - transaction object for mined transaction
* `hash` - `string` transaction hash
* `subscription`: `string` - subscription ID
With `hashesOnly` = `false`
* `result`:
* `removed` - `boolean` specifier if the transaction has been removed (re-orged)
* `transaction` - transaction object for mined transaction \*`blockHash`: `DATA`, 32 Bytes - hash of block that the transaction was mined in \*`blockNumber`: `QUANTITY` - `null` when it's pending. \*`from`: `DATA`, 20 Bytes - address of the sender. \*`gas`: `QUANTITY` - gas provided by the sender. \*`gasPrice`: `QUANTITY` - gas price provided by the sender in Wei. \*`hash`: `DATA`, 32 Bytes - hash of the transaction. \*`input`: `DATA` - the data send along with the transaction. \*`nonce`: `QUANTITY` - the number of transactions made by the sender prior to this one. \*`to`: `DATA`, 20 Bytes - address of the receiver. `null` when it's a contract creation transaction. \*`transactionIndex`: `QUANTITY` - `null` when its pending. \*`value`: `QUANTITY` - value transferred in Wei. \*`v`: `QUANTITY` - ECDSA recovery id \*`r`: `DATA`, 32 Bytes - ECDSA signature r \*`s`: `DATA`, 32 Bytes - ECDSA signature s
* `subscription`: `string` - subscription ID
