Extrinsics.io is an extrinsics building platform that provides an improved user interface and experience for users in the Polkadot and Kusama ecosystem. It has a fresh new take on building and signing extrinsics that enables both regular users and power users to better understand and utilise the extrinsic builder. It will also provide users of the currently available wallets with tools that help make calls to the network that are not currently available in any of those wallets.

Our goal with extrinsics.io is to build a platform that makes it easier for new users to understand and utilise the extrinsic builder with more comfort and ease while also making sure that power users can quickly get to what they are looking for when they have to build an extrinsic. Here are some key points that highlight those changes:

- Unified screen for encoding and decoding extrinsics

- Intuitive Decoder View

- An editable decoder UI

- A better interface for the encoder

You can take a look at the full proposal [here](https://docs.google.com/document/d/1Ty52DlBTx9Lf14vzYnIaIBoRC2kaRCU3EG9B_KRZd3E/edit?usp=sharing)

The platform would also support signing of extrinsics functions with both Kusama and Polkadot. We would start with supporting both Kusama and Polkadot networks with the option of extending it to other networks at a later stage.

The proposal consists of just one milestone and an estimated 3 months to complete. After Milestone 0 is completed we plan to make a report that will be shared on Polkassembly and Kusama Direction.


We would love to hear your feedback and get your thoughts around the project. Feel free to leave a comment below, or reach out via email, anytime.
