; }; A Sei Improvement Proposal (SIP) is a design document for a change to Sei. It might cover a new protocol feature, a change to how the project runs, or a convention for the wider ecosystem. Writing one is how you put an idea in front of the community, and how the reasoning behind a decision is recorded. Every SIP lives in the [sei-protocol/sips](https://github.com/sei-protocol/sips) repository, and the list below reads from it directly. Titles, statuses, authors, and section outlines come from the source files, not from a copy that can become outdated. A SIP is not the same as an on-chain governance proposal. The SIP holds the design and the reasoning. The on-chain proposal is the vote that enacts it. One SIP can take several governance proposals to carry out, as SIP-3 did. For the on-chain process, see [Governance](/learn/general-governance) and [Proposals](/learn/proposals). ## All proposals ## Proposal types Every SIP declares a type, and the type decides how much community consensus it needs. [SIP-1](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#sip-type) defines all three. | Type | Scope | Needs consensus | | - | - | - | | [Standard](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#standard) | Changes that affect most implementations of Sei, such as consensus, networking, RPC, EVM and CosmWasm behavior, and contract standards. It must also declare a category. | Yes | | [Process](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#process) | Changes around Sei rather than inside it, such as developer tooling, node and validator procedures, and the SIP process itself. | Yes | | [Informational](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#informational) | Guidelines or information for the community, with no change to the protocol or development environment. | No | ### Categories A Standard SIP must also declare one of five [categories](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#sip-category). | Category | Covers | | - | - | | Core | Consensus, execution, storage, and account signatures | | Networking | Mempool and network protocols | | Interface | RPC specifications and lower-level naming conventions | | Framework | EVM and CosmWasm contracts and primitives included in the Sei codebase | | Application | New EVM or CosmWasm standards and primitives that sit outside the Sei codebase | ## Status lifecycle A successful SIP usually moves through Draft, Review, Last Call, Final, Implemented, and Activated. Each card above shows the status recorded in that proposal's own source file. | Status | What it means | | - | - | | [Idea](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#idea) | Written, but not yet admitted to the process and not yet numbered. | | [Draft](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#draft) | An editor has accepted the formatting and assigned a number. The author now gathers community feedback. | | [Review](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#review) | The author has worked through early feedback. At least three assigned reviewers now give a formal review. | | [Fast Track](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#fast-track) | For proposals that already reached consensus outside the SIP process. It runs the same way as Review. | | [Last Call](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#last-call) | A final window for objections, usually at least one week. | | [Final](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#final) | Accepted, and the specification is now frozen. | | [Implemented](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#implemented) | Development is complete, but the feature is not yet live on Sei Mainnet. | | [Activated](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#activated) | Live on Sei Mainnet. | | [Stagnant](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#stagnant) | Inactive for four weeks while in Draft, Review, or Last Call. | | [Withdrawn](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#withdrawn) | The author has withdrawn the proposal. | | [Living](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#living) | A continuously updated proposal that never reaches Final, such as SIP-1 itself. | After a SIP reaches Final, nobody can withdraw or edit it. To change an accepted specification, submit a new SIP that extends or replaces the original. ## Guides for specific proposals SIP-3 and SIP-4 both affect how you use and build on Sei. These pages cover what they mean in practice. What SIP-3 changes for asset holders, and how to move off Cosmos-native addresses. Integration changes for exchanges and custodians that support Sei deposits and withdrawals. How Sei's EIP-1559 implementation works, including the parameters SIP-4 revises. Legacy Cosmos SDK and CosmWasm documentation, deprecated under SIP-3. ## Submit a proposal Anyone can author a SIP. Before you write one, discuss the idea with the community to find out whether the proposal is needed at all. [SIP-1](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md) defines the process, the header fields your file needs, and what authors and editors are each responsible for. Open a thread in [GitHub Discussions](https://github.com/sei-protocol/sips/discussions) to collect early feedback, especially from the people who would implement the change. Fork [sei-protocol/sips](https://github.com/sei-protocol/sips). In your fork, create your proposal at `sips/sip-temporary_title.md`. Put any images in `assets/sip-temporary_title/`. Start the file with the two-column header table. Follow the section structure described in [SIP format](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#sip-format). Keep the title under 64 characters. Do not end the title with a period. Submit the pull request from your fork. A [SIP editor](https://github.com/sei-protocol/sips/blob/main/sips/sip-1.md#sip-editor) reviews the formatting, assigns a number, moves the status to Draft, and opens the official comments thread. From Draft onward, you are responsible for keeping the proposal moving. An editor helps you find the right people to talk to, but does not push the process forward for you.
