+# Introduction
+
+IBC is a protocol that allows different blockchains to communicate with each
+other. It is a standard that defines how blockchains can send and receive
+messages to each other. This allows for the creation of a network of blockchains
+that can interact with each other.
+
+You can use the IBC protocol as a building block to create your own custom
+protocols on top of it, but you can also use existing protocols like the [ICS-20
+token transfer protocol]. In the following sections, we will explain how both of
+these work.

+## Basic Concepts
+
+In order to understand how IBC works, it is important to understand some basic
+concepts:
+
+- **Port**: An identifier that corresponds to a single module on a chain. One
+  module can have multiple ports. Each contract has its own unique port.
+- **Channel**: A connection between two ports on different blockchains that
+  allows them to send packets to each other. Each port can have multiple
+  channels.
+- **Relayer**: A service that is responsible for relaying packets between
+  blockchains. Anyone can run a relayer.
+- **Packet**: A piece of binary data that is sent through a channel. It can time
+  out if it is not delivered within a certain time frame.
+
+We will go into more detail on how these concepts are related to CosmWasm in the
+later sections, but this should give you some basic terminology to start with.
+If you want to learn more about IBC, you can read the [IBC specification] or
+check out the [IBC documentation].

+# Channel lifecycle
+
+A channel is a connection between two IBC ports that allows them to send packets
+to each other. In this section, we will cover how to establish a channel and how
+to close it. Since a channel is a connection between two ports, it can connect
+two chain modules, two contracts, or a module and a contract.
+
+## Establishing a channel
+
+In order to send packets between two chains, you need to establish a channel
+between them. This process involves two calls per chain. They are described
+below. Once the channel is established, you can start sending packets through
+it, which we will cover in the next section.
+
+### Channel open
+
+{/* `ibc_channel_open` called on both chains, explain differences */}
+
+### Channel connect
+
+{/* `ibc_channel_connect` called on both chains, explain differences */}
+
+## Closing a channel

+
+# Using existing protocols
+
+The easiest way to use IBC is to use an already existing protocol. These
+protocols can either be implemented by the chain itself or by another contract.
+
+One example for the former is the `IbcMsg::Transfer` message, which causes an
+ICS20 transfer. This message is included in the CosmWasm standard library and
+causes the chain's IBC transfer module to send tokens to another chain.
+
+An example for the latter is the Nois protocol. It provides a proxy contract
+that handles all the IBC logic for you. For more information on Nois, check the
+[Nois documentation](https://docs.nois.network/dapp_devs/use_nois_randomness.html).
+We will later cover how to implement your own IBC protocol.
+
+## Example: `IbcMsg::Transfer`
+
+To initiate an ICS20 transfer, you need to attach an `IbcMsg::Transfer` message
+to your contract response like this:
+
+```rust template="execute"
+// construct the transfer message
+let msg = IbcMsg::Transfer {
+    channel_id: "channel-0".to_string(),
+    to_address: "cosmos1exampleaddress".to_string(),
+    amount: Coin::new(123u128, "ucoin"),
+    timeout: env.block.time.plus_seconds(60).into(),
+    memo: None,
+};
+
+// attach the message and return the response
+Ok(Response::new().add_message(msg))
+```
+
+The `channel_id` is the identifier of the channel you want to use for the
+transfer. Which channel that should be depends on the source and destination
+chain. You can find out the correct channel ID using a
+[block explorer](https://www.mintscan.io/cosmos/relayers).
+
+The `to_address` is the address on the _destination chain_ that should receive
+the tokens.
+
+The `amount` is the number and denomination of tokens to send. On the
+destination chain, the same amount will be received, but the denomination will
+be of the form `ibc/HASH`, where `HASH` is a SHA256 hash uniquely identifying
+the channel and the source chain denomination. To learn more about this, take a
+look at the [Cosmos Developer Portal].
+
+The `timeout` can either be a timestamp or a block height, as measured on the
+destination chain. It is used to prevent the transfer from being stuck in limbo
+if the destination chain does not receive the packet.
+
+The `memo` is an optional field that can be used to attach a message to the
+transfer. It is often used for additional functionality like
+[packet-forward-middleware] or IBC Callbacks.
+
+[packet-forward-middleware]:
+  https://github.com/cosmos/ibc-apps/tree/main/middleware/packet-forward-middleware
+[Cosmos Developer Portal]:
+  https://tutorials.cosmos.network/tutorials/6-ibc-dev/#understand-ibc-denoms
+
+## ADR-8: IBC Callbacks
+
+When you send an ICS20 transfer as described above, you do not get any feedback
+on whether the transfer was successful or not and the destination does not get
+informed of its newfound wealth. To solve this problem, the ADR-8 specification
+was created. On the source chain, it provides callbacks when an IBC packet was
+acknowledged or timed out. On the destination chain, it triggers callbacks when
+a packet is received.
+
+<Callout>
+  To receive callbacks, the chain needs to support IBC Callbacks for the message
+  type.
+</Callout>
+
+### Enabling IBC Callbacks for a message
+
+You need to explicitly opt-in to IBC Callbacks for each message. In order to do
+this, you need to add some metadata to the message, including who should receive
+the callbacks.
+
+<Callout>
+  The exact data format and how to add it to the message can vary, but for the
+  `IbcMsg::Transfer` message, this data is in JSON format and needs to be added
+  to the `memo` field.
+</Callout>
+
+To make this as easy as possible, we provide a helper type `IbcCallbackRequest`
+that you can use to generate the JSON:
+
+{/* TODO: add `template="execute"` once IBC Callbacks are merged */}
+
+```rust
+let _ = IbcMsg::Transfer {
+    to_address: "cosmos1exampleaddress".to_string(),
+    channel_id: "channel-0".to_string(),
+    amount: Coin::new(10u32, "ucoin"),
+    timeout: Timestamp::from_seconds(12345).into(),
+    memo: Some(to_json_string(&IbcCallbackRequest::both(IbcSrcCallback {
+        address: env.contract.address,
+        gas_limit: None,
+    }, IbcDstCallback {
+        address: to_address.clone(),
+        gas_limit: None,
+    })).unwrap()),
+};
+```
+
+As you can see, you can request callbacks for both the source and destination
+chain. However, you can also request callbacks for only one of them. For this,
+you need to provide the address that should receive the callback and you can
+optionally set a gas limit for the callback execution. Please take a look at the
+`IbcCallbackRequest` docs for more information.
+
+<Callout>
+  The `address` of the source callback always needs to be the contract address
+  that sends the message (`env.contract.address`). Otherwise, the callback will
+  error and the contract will not be called.
+</Callout>
+
+### Entrypoints
+
+TODO
+
+- two new entrypoints
+  - `ibc_source_chain_callback`
+  - `ibc_destination_chain_callback`
+
+---
+
+Notes:
