### Filters

See [proto/geyser.proto](proto/geyser.proto).

#### Slots

   - `enabled` — broadcast slots updates

#### Account

Accounts can be filtered by:

   - `any` — stream all accounts, if active all other filters should be disabled
   - `account` — acount Pubkey, match to any Pubkey from the array
   - `owner` — account owner Pubkey, match to any Pubkey from the array

All fields in filter are optional but at least 1 is required. Fields works as logical `AND`. Values in the arrays works as logical `OR`.

#### Transactions

   - `any` — stream all transactions
   - `vote` — enable/disable broadcast `vote` transactions
   - `failed` — enable/disable broadcast `failed` transactions

#### Blocks

   - `any` — stream all blocks
