A Frax Improvement Proposal (FIP) is the canonical document and process for evolving the Frax protocol's core design. It standardizes how changes to smart contracts, economic parameters, and system interfaces are proposed, debated, and implemented. Unlike standard veFXS governance votes that often handle parameter adjustments or gauge weights, a FIP typically introduces new technical architecture, such as a novel Algorithmic Market Operations (AMO) controller, a modification to the Fraxtal sequencer fee-recipient logic, or a new liquid staking derivative (LSD) vault standard.

introduction
PROTOCOL EVOLUTION STANDARD
What is a Frax Improvement Proposal (FIP)?
A Frax Improvement Proposal (FIP) is the formal technical specification for proposing changes to the Frax protocol, including its stablecoin mechanisms, Fraxtal L2, and governance logic.
The FIP lifecycle moves from ideation and community discussion through formal specification, editorial review, and finally to an on-chain binding vote. This pipeline ensures that complex technical changes are rigorously documented before they reach the veFXS electorate. For builders and integrators, a FIP is the primary signal of an impending shift in minting, redemption, or reward logic. A FIP proposing a new AMO, for example, directly impacts the collateral composition backing FRAX, while a Fraxtal core specification FIP can alter the L2's block-gas limit or fee-burn mechanism, requiring node operators and infrastructure providers to prepare for coordinated upgrades.
Protocol architects and contributors who need to understand the submission pipeline and technical evolution path should treat the FIP repository as the authoritative source of design rationale. Teams planning to propose a new controller, bridge interface, or oracle integration standard must align their technical specification with the established FIP format. Chainscore Labs can assist teams in drafting, reviewing, or stress-testing new FIPs before submission, ensuring that the technical specification is sound, the economic risk framework is addressed, and the implementation path is clearly defined for the veFXS governance review.
LIFECYCLE AND SUBMISSION PIPELINE
FIP Process Quick Facts
Key operational facts about the FIP lifecycle, roles, and how proposals differ from standard veFXS governance votes.
| Area | What changes | Who is affected | Action |
|---|---|---|---|
Proposal Initiation | A new FIP is introduced to the Frax community for discussion before formal drafting | Protocol architects, core contributors, community members | Engage in forum discussion to refine the idea before committing to a formal draft |
Author and Editor Roles | FIP Authors champion the proposal; FIP Editors review for formatting, clarity, and procedural correctness | Proposal authors, FIP editors, governance delegates | Authors must collaborate with editors to ensure the FIP meets the required template and quality bar |
Status Lifecycle | A FIP moves through stages: Idea, Draft, Review, Last Call, Accepted, Final, or Deferred/Withdrawn | All stakeholders tracking protocol evolution | Monitor the FIP repository to track the status of proposals that affect your system or integration |
On-Chain Voting Distinction | A FIP is a technical specification; a separate veFXS governance vote is required for on-chain execution | Governance delegates, veFXS holders, protocol operators | Do not assume a merged FIP implies automatic protocol change; verify the associated on-chain vote outcome |
Technical Specification | The FIP must contain a precise technical specification and rationale for the proposed change | Integrators, auditors, node operators | Review the technical specification to assess implementation complexity and integration impact |
Core vs. Fraxtal vs. Interface FIPs | FIPs are categorized by the subsystem they affect: Core (FRAX/FXS), Fraxtal (L2), or Interface (wallets, APIs) | Node operators, wallet teams, DeFi protocols | Identify the FIP category to determine if your team needs to perform a client upgrade, contract migration, or API change |
Canonical Source | The authoritative list and status of all FIPs is maintained in the official Frax GitHub repository | All builders and integrators | Always verify the current status and merged specification against the canonical GitHub repository before acting |

FRAX IMPROVEMENT PROPOSAL PROCESS
The FIP Lifecycle: From Ideation to Execution
A technical walkthrough of the FIP pipeline, from drafting and community discussion to on-chain voting and protocol execution.
The Frax Improvement Proposal (FIP) lifecycle is the formal mechanism for evolving the Frax protocol's core contracts, economic parameters, and technical standards. Unlike standard veFXS gauge votes that adjust existing pool weights, a FIP is required to introduce new AMO controllers, modify the stablecoin's collateralization logic, upgrade the Fraxtal rollup's OP Stack modifications, or alter the fundamental rules of the system. The process is designed to ensure that any change to the protocol's technical architecture undergoes rigorous peer review, community scrutiny, and formal on-chain ratification before a single line of code is executed on mainnet.
The lifecycle begins with an author drafting a specification in the FIP repository, following a template that mandates clear technical rationale, implementation details, and a security considerations section. This draft must then be socialized on the Frax governance forum and community calls, where protocol architects, risk teams, and integrators can stress-test the proposal's assumptions. A FIP editor—a role responsible for maintaining technical quality and formatting consistency—reviews the draft before assigning a formal FIP number. This gatekeeping step prevents poorly specified or malicious proposals from advancing. Once numbered, the FIP enters a final call period, after which it is encoded into an on-chain proposal for a veFXS-weighted vote. Successful execution triggers the specified contract upgrades or parameter changes directly on the protocol.
For builders and operators, understanding this pipeline is critical for anticipating breaking changes. A FIP that modifies the Fraxtal sequencer's fee-recipient logic or alters the sfrxETH vault's reward distribution will directly impact downstream integrations, wallets, and exchange deposit/withdrawal logic. Teams that fail to monitor the FIP repository and governance forum risk being caught off-guard by an activated proposal. Chainscore Labs assists protocol architects and contributors by providing technical review of FIP drafts before submission, stress-testing economic assumptions, and auditing the implementation code to ensure it matches the specification's intent, reducing the risk of a flawed proposal reaching the on-chain voting stage.
FIP LIFECYCLE ACTORS
Roles and Responsibilities
FIP Authors
Authors are the primary drivers of a proposal. They are responsible for researching the technical change, writing the specification, and building consensus within the community.
Key Responsibilities:
- Draft the FIP document following the canonical template, ensuring the specification is technically complete.
- Engage with the community on the Frax governance forum to socialize the idea and gather informal feedback before formal submission.
- Iterate on the specification in response to feedback from editors and peer reviewers.
- Provide a reference implementation or detailed technical rationale sufficient for auditors and integrators to evaluate the change.
- Coordinate with the FIP editor to move the proposal through the status workflow (Idea → Draft → Proposed).
Authors do not unilaterally activate proposals. They must rely on the veFXS governance process for final approval.

FIP LIFECYCLE & INTEGRATION RISK
Impact on Protocol Evolution
The FIP process is the primary engine for technical change in the Frax ecosystem. Understanding the lifecycle from ideation to on-chain execution is critical for teams that must adapt to new stablecoin mechanisms, L2 modifications, and reward logic.
01
AMO and Collateral Logic Changes
FIPs that introduce new Algorithmic Market Operations controllers or modify the Collateralization Ratio directly alter the minting and redemption mechanics of FRAX. Integrators must review these proposals to update their risk models for backing composition, custodial exposure, and potential de-peg vectors. A new AMO can shift protocol liquidity and yield sources overnight, requiring exchanges and yield aggregators to rebalance their FRAX support.
02
Fraxtal Sequencer and Fee Rule Updates
Proposals targeting Fraxtal can modify the OP Stack configuration, including the unique fee-recipient logic that buys back and burns FXS. Node operators and infrastructure providers must track these FIPs to ensure their client configurations remain compatible with the canonical chain. A change in block-gas limit or sequencer ordering policy can break assumptions in deployed smart contracts, requiring immediate integration testing.
03
Gauge and veFXS Reward Logic Modifications
FIPs that adjust the veFXS boost multiplier or gauge weight voting mechanics directly impact liquidity mining incentives. Protocols that depend on FXS emissions to attract liquidity must monitor the FIP pipeline to forecast changes in reward accrual. A seemingly minor parameter change can invalidate existing yield strategies, requiring DAOs and treasury managers to re-vote or migrate liquidity pools.
04
Cross-Chain Asset Standard Upgrades
When a FIP proposes migrating a canonical token like FRAX or sFRAX to a new bridge standard such as xERC20 or OFT, multi-chain protocols and bridge operators face a mandatory integration window. Failure to upgrade wrapper contracts or update oracle price feeds for the new token address can result in broken composability and stranded liquidity. Teams must stress-test their cross-chain dependencies against the proposed standard.
05
Oracle and Price Feed Circuit Breaker Adjustments
FIPs that recalibrate the dual-oracle model's deviation thresholds or add new price feed sources change the security assumptions for all dependent lending markets and AMOs. A tighter circuit breaker can halt minting during volatility, while a looser one increases manipulation risk. Risk teams must simulate the impact of proposed parameters on Fraxlend liquidations and FRAX peg stability before the proposal reaches an on-chain vote.

Process Risks and Bottlenecks
Identifies operational risks and process bottlenecks in the FIP lifecycle that can delay protocol upgrades, introduce security gaps, or create governance contention.
| Area | Failure Mode | Who is affected | Mitigation or Action |
|---|---|---|---|
Authoring and Specification | Incomplete or ambiguous technical specification leads to implementation divergence | Protocol architects, smart contract developers, auditors | Engage Chainscore for pre-submission specification review and stress-testing against edge cases |
Community Deliberation | Low engagement on critical proposals results in uninformed voting or governance apathy | veFXS holders, governance delegates, risk teams | Monitor forum and Discord activity; delegates should commission independent impact assessments for complex FIPs |
Off-chain to On-chain Transition | Discrepancy between off-chain proposal text and on-chain executable code introduces malicious or erroneous state changes | Multisig signers, governance delegates, integration teams | Verify on-chain payload bytecode against the canonical FIP specification before voting; Chainscore can perform differential analysis |
Vote Delegation and Participation | Concentrated voting power or low quorum allows a small coalition to pass contentious parameter changes | Liquidity providers, protocol treasuries, retail veFXS holders | Delegate to active, technically literate representatives; monitor vote power distribution ahead of critical economic votes |
AMO and Collateral Parameter Changes | Rushed governance execution of AMO parameter changes without adequate simulation causes unintended market impact or de-peg risk | FRAX holders, Fraxlend borrowers, Curve pool LPs | Simulate parameter changes in a fork environment; Chainscore offers economic risk assessment for AMO and CR modifications |
Fraxtal Upgrade Coordination | Sequencer or bridge upgrade FIPs lack clear node operator communication, leading to network halts or consensus failures | Fraxtal node operators, RPC providers, exchanges, bridges | Require mandatory upgrade readiness windows in FIPs; Chainscore provides node deployment validation and upgrade rehearsal support |
Security Review Bottleneck | Insufficient auditor capacity or time pressure delays critical security reviews before an FIP's on-chain execution | Protocol treasury, end-users, integrators | Commission parallel security reviews early in the FIP lifecycle; Chainscore can supplement formal audits with targeted integration and logic reviews |
READINESS AND IMPACT ASSESSMENT
FIP Author and Integrator Checklist
A practical checklist for FIP authors preparing a submission and for protocol integrators assessing the impact of a live FIP. This covers technical specification quality, governance readiness, and operational integration steps.
What to check: Does the FIP document clearly specify the technical changes, including new contract interfaces, state transitions, and failure modes? The specification must be unambiguous enough for an independent team to implement it without the author's guidance.
Why it matters: Incomplete specs lead to integration errors, security vulnerabilities, and governance decisions made on unclear premises. For integrators, an underspecified FIP creates uncertainty about how existing systems (wallets, oracles, bridges) will interact with the new logic.
Readiness signal: The FIP includes a formal 'Specification' section with clear data structures, function signatures, and edge-case behavior. A reference implementation or test suite is available for review. Integrators can trace the exact impact on their dependency stack.

FIP LIFECYCLE FAQ
Frequently Asked Questions
Answers to common questions about the FIP process, submission requirements, and how FIPs differ from standard governance votes.
A FIP is a formal technical specification that proposes a change to the Frax protocol's core mechanisms, standards, or architecture. It follows a structured lifecycle from ideation through community discussion, editorial review, and finally on-chain voting. Standard veFXS governance votes typically handle parameter adjustments (e.g., gauge weights, collateral ratios) that operate within existing protocol logic. FIPs are required when the change introduces new smart contract logic, modifies existing standards, or alters the protocol's economic design. If a proposal requires new code to be written and audited, it should follow the FIP process.
