Both Lockup and Flow Protocols wrap every stream in an ERC-721 non-fungible token (NFT), making the stream recipient the
owner of the NFT. The recipient can transfer the NFT to another address, and this also transfers the right to withdraw
funds from the stream, including any funds already streamed.

6. **Withdraw:** it is publicly callable as long as `to` is set to the recipient. However, a stream’s recipient is
allowed to withdraw funds to any address.
+
+## Key Definitions
+
+The definitions below will help you understand some terms used in Sablier Flow:
+
+### Stream balance
+
+Stream balance is the token balance of a stream. It increases when funds are deposited into a stream, and decreases when
+the sender refunds from it or when a withdrawal happens.
+
+### Total debt
+
+Total debt is the amount of tokens owed to the recipient. This value is further divided into two sub-categories:
+
+- **Covered debt:** The part of the total debt that covered by the stream balance. This is the same as the
+ **withdrawable amount**, which is an alias.
+- **Uncovered debt:** The part of the total debt that is not covered by the stream balance. This is what the sender owes
+ to the stream.
+
+```math
+\text{total debt} = \text{covered debt} + \text{uncovered debt}
+```
+
+### Snapshot debt and Snapshot time
+
+A snapshot is an event during which snapshot debt and snapshot time of a Flow stream are updated. **Snapshot debt** is
+the debt accumulated since the previous snapshot. The UNIX timestamp at which snapshot debt is updated is called
+**Snapshot time**.
+
+At snapshot, the following calculations are taking place:
+
+```math
+\text{snapshot debt} = \text{previous snapshot debt} + \underbrace{
+rps \cdot (\text{block.timestamp} - \text{snapshot time})}_\text{ongoing debt}
+\text{snapshot time} = \text{block.timestamp}
+```
+
+Therefore, at any point in time, total debt can also be defined as:
+
+```math
+\text{total debt} = \text{snapshot debt} + \text{ongoing debt}
+```
+
+## Lifecycle
+
+1. A Flow stream is created with an `rps`, a `sender` and a `recipient` address.
+2. During the lifecycle of the stream, all the functions enclosed inside the dotted rectangle (diagram below) can be
+ called any number of times. There are some limitations though, such as `restart` can only be called if the stream is
+ `paused`.
+3. Any party can call `void` to terminate it. Only withdraw and refund are allowed on a voided stream.

+# Stream Statuses
+
+A Flow stream can have one of five distinct statuses:
+
+| Status | Description |
+| ------------------- | ----------------------------------------------------------------------------------- |
+| STREAMING_SOLVENT | Active stream with total debt not exceeding stream balance. |
+| STREAMING_INSOLVENT | Active stream with total debt exceeding stream balance. |
+| PAUSED_SOLVENT | Paused stream with total debt not exceeding stream balance. |
+| PAUSED_INSOLVENT | Paused stream with total debt exceeding stream balance. |
+| VOIDED | Paused stream that can no longer be restarted and has forfeited its uncovered debt. |
+
+## Stream characteristics
+
+A stream can have the following characteristics:
+
+| Characteristic | Statuses | Description |
+| :------------- | :---------------------------------------- | :------------------------------------------------------ |
+| Streaming | STREAMING_SOLVENT, STREAMING_INSOLVENT | Non-zero rps. |
+| Paused | PAUSED_SOLVENT, PAUSED_INSOLVENT, VOIDED | Zero rps. |
+| Solvent | STREAMING_SOLVENT, PAUSED_SOLVENT, VOIDED | Total debt not exceeding the stream balance. |
+| Insolvent | STREAMING_INSOLVENT, PAUSED_INSOLVENT | Total debt exceeding the stream balance. |
+
+## Diagram

+
+## Q&A
+
+### Q: What is a null stream?
+
+A: An id that does not reference a created stream. Trying to interact with a null stream will result in a revert.
+
+### Q: What to do with a stream status?
+
+A: Knowing the status of a stream can inform your decision making. For example, if a stream is `STREAMING_INSOLVENT`,
+that means the stream is active but has insufficient balance. As a sender, you should deposit into the stream so that
+your recipient can withdraw the streamed amount without any hiccups. And if you don't want to continue the stream, you
+can pause it.
+
+### Q: Who can make a stream `VOIDED`?
+
+A: Both sender and recipient can void the stream. This is especially useful when either party wants to stop the stream
+immediately. Once a stream is voided, it cannot be restarted. If there is uncovered debt, it will be reset to 0. So to
+ensure that your recipient does not lose on any streamed amount, you can deposit into the stream before voiding it.

+title: "Configure Your Local Environment"
+---
+
+In this guide, we will go through the steps to set up a local development environment for building onchain integrations
+with Flow. We will use Foundry to install Flow as a dependency, and run a few simple tests.
+
+At the end, you’ll have a development environment set up that you can use to build the rest of the examples under
+"Guides", or start your own integration project.
+
+## Pre-requisites
+
+You will need the following software on your machine:
+
+- [Git](https://git-scm.com/downloads)
+- [Foundry](https://github.com/foundry-rs/foundry)
+- [Node.js](https://nodejs.org/en/download)
+- [Bun](https://bun.sh)
+
+In addition, familiarity with [Ethereum](https://ethereum.org/) and [Solidity](https://soliditylang.org/) is requisite.
+
+## Quick start
+
+We put together a template repository that you can use to get started quickly. This repository features a basic project
+structure, pre-configured Flow imports, and a selection of sample contracts and tests.
+
+:::tip
+
+Make sure you are using the latest version of Foundry by running `foundryup`.
+
+:::
+
+To install the template, simply execute the following commands:
+
+```shell
+$ mkdir sablier-integration-template
+$ cd sablier-integration-template
+$ forge init --template sablier-labs/sablier-integration-template
+$ bun install
+```
+
+Then, hop to the `Run a Fork Test` section to complete your set up and start developing.
+
+## Start from scratch
+
+Foundry is a popular development toolkit for Ethereum projects, which we have used to build the Sablier Protocols. For
+the purposes of this guide, Foundry will provide us with the tooling needed to compile and test our contracts.
+
+Let's use this command to spin up a new Foundry project:
+
+```shell
+$ forge init my-project
+$ cd my-project
+```
+
+:::note
+
+You might notice that the CLI is `forge` rather than `foundry`. This is because Foundry is a toolkit, and `forge` is
+just one of the tools that comes with it.
+
+:::
+
+Once the initialization completes, take a look around at what got set up:
+
+```tree
+├── foundry.toml
+├── script
+├── src
+└── test
+```
+
+The folder structure should be intuitive:
+
+- `src` is where you'll write Solidity contracts
+- `test` is where you'll write tests (also in Solidity)
+- `script` is where you'll write scripts to perform actions like deploying contracts (you guessed it, in Solidity)
+- `foundry.toml` is where you can configure your Foundry settings, which we will leave as is in this guide
+
+Let's install the FLow Node.js packages using Bun:
+
+```shell
+$ bun add @sablier/flow
+```
+
+Bun will download the Flow contracts, along with their dependencies, and put them in the `node_modules` directory.
+
+Let's remap the package names to point to the installed contracts. This step is required so that the Solidity compiler
+can find the Flow contracts when you import them:
+
+```shell
+$ echo "@sablier/flow=node_modules/@sablier/flow/" >> remappings.txt
+$ echo "@openzeppelin/contracts/=node_modules/@openzeppelin/contracts/" >> remappings.txt
+$ echo "@prb/math/=node_modules/@prb/math/" >> remappings.txt
+```
+
+That's it! You should now have a functional development environment to start building onchain Flow integrations. Let's
+run a quick test to confirm everything is set up properly.
+
+## Sample contract
+
+Delete the `src/Counter.sol` and `test/Counter.t.sol` files generated by Forge, and create a new file:
+`src/FlowStreamCreator.sol`.
+
+Paste the following code into `src/FlowStreamCreator.sol`.
+
+```solidity reference title="Flow Stream Creator"
+https://github.com/sablier-labs/examples/blob/main/flow/FlowStreamCreator.sol
+```
+
+Let's use Forge to compile this contract:
+
+```shell
+$ forge build
+```
+
+If the contract was compiled correctly, you should see this message:
+
+```text
+[⠢] Compiling...
+[⠰] Compiling { number } files with { compiler }
+[⠒] Solc { compiler } finished in { time }
+Compiler run successful
+```
+
+:::info
+
+The minimum Solidity version supported by the Flow contracts is v0.8.13.
+
+:::
+
+## Next steps
+
+Congratulations! Your environment is now configured, and you are prepared to start building. Explore the guides section
+to discover various Flow features available for integration.
+
+As far as Foundry is concerned, there is much more to uncover. If you want to learn more about it, check out the
+[Foundry Book](https://book.getfoundry.sh/), which contains numerous examples and tutorials. A deep understanding of
+Foundry will enable you to create more sophisticated integrations with Flow.

+With the exception of the [admin functions](/concepts/governance#flow), all functionalities in Flow can only be

+
+Every stream has a sender and a recipient. Recipients can approve third parties to take actions on their behalf. An

+### \_preventDelegateCall
+
+This function checks whether the current call is a delegate call, and reverts if it is.

+- A private function is used instead of inlining this logic in a modifier because Solidity copies modifiers into every

+
+## Structs
+
+### Stream
+
+Struct representing Flow streams.
+
+_The fields are arranged like this to save gas via tight variable packing._
+
+```solidity
+struct Stream {
+ uint128 balance;
+ UD21x18 ratePerSecond;
+ address sender;
+ uint40 snapshotTime;
+ bool isStream;
+ bool isTransferable;
+ bool isVoided;
+ IERC20 token;
+ uint8 tokenDecimals;
+ uint256 snapshotDebtScaled;
+}
+```
+
+**Properties**
+
+| Name | Type | Description |
+| -------------------- | --------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `balance` | `uint128` | The amount of tokens that are currently available in the stream, denoted in token's decimals. This is the sum of deposited amounts minus the sum of withdrawn amounts. |
+| `ratePerSecond` | `UD21x18` | The payment rate per second, denoted as a fixed-point number where 1e18 is 1 token per second. For example, to stream 1000 tokens per week, this parameter would have the value $(1000 * 10^18) / (7 days in seconds)$. |
+| `sender` | `address` | The address streaming the tokens, with the ability to pause the stream. |
+| `snapshotTime` | `uint40` | The Unix timestamp used for the ongoing debt calculation. |
+| `isStream` | `bool` | Boolean indicating if the struct entity exists. |
+| `isTransferable` | `bool` | Boolean indicating if the stream NFT is transferable. |
+| `isVoided` | `bool` | Boolean indicating if the stream is voided. Voiding any stream is non-reversible and it cannot be restarted. Voiding an insolvent stream sets its uncovered debt to zero. |
+| `token` | `IERC20` | The contract address of the ERC-20 token to stream. |
+| `tokenDecimals` | `uint8` | The decimals of the ERC-20 token to stream. |
+| `snapshotDebtScaled` | `uint256` | The amount of tokens that the sender owed to the recipient at snapshot time, denoted as a 18-decimals fixed-point number. This, along with the ongoing debt, can be used to calculate the total debt at any given point in time. |
+
+## Enums
+
+### Status
+
+Enum representing the different statuses of a stream.
+
+Explanations for the two types of streams:
+
+1. Streaming: when the total debt is increasing.
+2. Paused: when the total debt is not increasing.
+
+**Notes:**
+
+- STREAMING_SOLVENT Streaming stream when there is no uncovered debt.
+
+- STREAMING_INSOLVENT Streaming stream when there is uncovered debt.
+
+- PAUSED_SOLVENT Paused stream when there is no uncovered debt.
+
+- PAUSED_INSOLVENT Paused stream when there is uncovered debt.
+
+- VOIDED Paused stream with no uncovered debt and it cannot be restarted.
+
+```solidity
