 ### Architecture Decision Records (ADR)
 
 When proposing an architecture decision for the ibc-go, please create an [ADR](./docs/architecture/README.md) so further discussions can be made. We are following this process so all involved parties are in agreement before any party begins coding the proposed implementation. Please use the [ADR template](./docs/architecture/adr-template.md) to scaffold any new ADR. If you would like to see some examples of how these are written refer to ibc-go's [ADRs](./docs/architecture/). Solidified designs that will be implemented in ibc-go (and do not have a spec). They should document the architecture that will be built. Most design feedback should be gathered before the initial draft of the ADR. ADR's can/should be written for any design decisions we make which may be changed at some point in the future.

 ## Ecosystem
 
-Discover the applications, middleware and light clients developed by other awesome teams in the ecosystem:
-
-In the table below
-`app` refers to IBC application modules for custom use cases and
-`middleware` refers to modules that wrap an IBC application enabling custom logic to be executed.

-|Description|Repository|Type|
-|----------|----------|----|
-|An application that enables on chain querying of another IBC enabled chain utilizing `baseapp.Query`. Both chains must have implemented the query application and ICA (for queries requiring consensus).|[async-icq](https://github.com/strangelove-ventures/async-icq)|`app`|
-|An application that enables on chain querying of another IBC enabled chains state without the need for the chain being queried to implement the application.|[interchain-queries](https://github.com/ingenuity-build/interchain-queries)|`app`|
-|An application that enables on chain querying of another IBC enabled chains state without the need for the chain being queried to implement the application. Similar to the interchain-queries application in the row above but without callbacks.|[query](https://github.com/defund-labs/defund/tree/main/x/query)|`app`|
-|An application that enables cross chain NFT transfer.|[NFT Transfer (ICS 721)](https://github.com/bianjieai/nft-transfer)|`app`|
-|Middleware enabling a packet to be sent to a destination chain via an intermediate chain, e.g. going from Juno to Osmosis via the Hub.|[packet-forward-middleware](https://github.com/strangelove-ventures/packet-forward-middleware)|`middleware`|
-|Middleware enabling the recovery of tokens sent to unsupported addresses.|[recovery](https://github.com/evmos/evmos/tree/main/x/recovery)|`middleware`|
-|Middleware that limits the in or out flow of an asset in a certain time period to minimise the risks of cross chain token transfers. This is implemented as a middleware wrapping ICS20 with the rate limiting logic implemented by cosmwasm contracts|[ibc-rate-limit](https://github.com/osmosis-labs/osmosis/tree/main/x/ibc-rate-limit)|`middleware`|
