TIPs are improvement proposals for bettering the IOTA technology stack.
Building the IOTA ecosystem is a community effort, therefore we welcome anyone to propose, discuss and debate ideas that will later become formalized TIPs.
Do you have an idea how to improve the IOTA technology stack?
- Head over to the discussions page to browse already submitted ideas or share yours!
- Once your idea is discussed, you can submit a draft TIP (template here as a PR to the repository.
- You will receive feedback from the TIP Editors and review from core devs.
- Once accepted, your TIP is merged as Draft.
- It is your responsibility to drive its implementation and to present a clear plan on how the new feature will be adopted by the network.
- Once implementation is ready and testing yields satisfactory result, the TIP becomes Proposed.
- Proposed TIPs that are supported by majority of the network become Active.
You may find more information about the TIP Process in TIP-1.
Stardust is the next upgrade of the IOTA protocol that adds tokenization and smart contract chain support besides many more improvements. Browse the list of TIPs below with the Stardust tag to learn more about what changes.

- The Status of a TIP reflects its current state with respect to its progression to being supported on the IOTA mainnet.
DraftTIPs are work in progress. They may or may not have a working implementation on a testnet.
ProposedTIPs are demonstrated to have a working implementation. These TIPs are supported on Shimmer, the staging network of IOTA.
ActiveTIPs are supported on the IOTA mainnet.
