 # Centralized Sequencer
+
+centralized-sequencer is an implementation of the [Generic Sequencer interface](https://github.com/rollkit/go-sequencing)
+for modular blockchains. It runs a gRPC service,
+which can be used by rollup clients to sequence transactions to Celestia da.

+
+## Minimum requirements
+
+| Requirement | Notes          |
+| ----------- |----------------|
+| Go version  | 1.22 or higher |
+
+## Installation
+
+```sh
+git clone https://github.com/rollkit/centralized-sequencer.git
+cd centralized-sequencer
+make build
+./build/centralized-sequencer -h
+```
+
+## Usage
+
+centralized-sequencer exposes a gRPC service that can be used with any gRPC client to
+sequence rollup transactions to the celestia network.
+
+## Example
+
+Run centralized-sequencer by specifying DA network details:
+
+```sh
+    ./build/centralized-sequencer -da_address <da_address> -da_auth_token <da_auth_token> -da_namespace $(openssl rand -hex 10)
+```
+
+## Flags
+
+| Flag                         | Usage                                   | Default                     |
+| ---------------------------- |-----------------------------------------|-----------------------------|
+| `batch-time`            | time in seconds to wait before generating a new batch | 2 seconds |
+| `da_address`              | DA address | `http:////localhost:26658`|
+| `da_auth_token`               | auth token for the DA | `""` |
+| `da_namespace`              | DA namespace where the sequencer submits transactions | `""` |
+| `host`                | centralized sequencer host            | localhost |
+| `port`             | centralized sequencer port | 50051 |
+| `listen-all` |listen on all network interfaces (0.0.0.0) instead of just localhost|disabled|
+
+See `./build/centralized-sequencer --help` for details.
