# Account updates

Stream account writes over Dragon's Mouth gRPC by adding an accounts filter to your SubscribeRequest.

## Filter

`SubscribeRequestFilterAccounts`, keyed by a filter label:

**`account`** · repeated string: Account pubkeys to match, base-58 encoded.

**`owner`** · repeated string: Match accounts owned by these program pubkeys.

**`filters`** · repeated SubscribeRequestFilterAccountsFilter: Extra filters: `memcmp`, `datasize`, `token_account_state`, or `lamports`.

**`nonempty_txn_signature`** · optional bool: `true` delivers only writes that carry a transaction signature, `false` only writes without one.

**`cuckoo_accounts_filter`** · optional CuckooFilter: Compressed cuckoo filter for very large account sets.

## Subscribe request

{% tabs %}
{% tab title="grpcurl" %}

```bash
# <proto-dir>: a folder holding geyser.proto and solana-storage.proto (the server has no gRPC reflection)
grpcurl \
  -proto geyser.proto -import-path <proto-dir> \
  -d '{"accounts": {"usdc": {"account": ["EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"]}}, "commitment": "CONFIRMED"}' \
  -H "x-token: <your-token>" \
  <your-endpoint>.mainnet.rpcpool.com:443 \
  geyser.Geyser/Subscribe
```

{% endtab %}
{% endtabs %}

## Update

Each write arrives as a `SubscribeUpdate` with `account` set (`SubscribeUpdateAccount`):

**`account`** · SubscribeUpdateAccountInfo: The account: `pubkey`, `lamports`, `owner`, `executable`, `rent_epoch`, `data`, `write_version`, `txn_signature`.

**`slot`** · uint64: Slot at which the write occurred.

**`is_startup`** · bool: True if the update is part of the initial startup snapshot.

**`bank_id`** · optional uint64: Bank instance that produced the update. A slot can have more than one bank, so use (`slot`, `bank_id`) to tell them apart. Not set when `is_startup` is true.
