- Compound will deprecate its Polygon and Unichain Comets after a Gauntlet proposal cited low usage and unnecessary complexity.
- The plan would reduce collateral factors to zero, set supply caps to zero and prevent new supply or collateral use on those deployments.
- Existing users would need to withdraw or migrate positions as Compound redirects development and security resources toward primary markets, future innovations and more efficient protocol operations.
Compound Finance is moving to deprecate its Polygon and Unichain Comets after a Gauntlet proposal argued that the deployments no longer justify their operational footprint. Discussed on the Compound Governance Forum on July 10, 2026, the plan would reduce collateral factors to zero and set supply caps to zero for both Comets. The move sounds technical, but its signal is broader: Compound is choosing concentration over chain-by-chain sprawl, prioritizing markets that show meaningful adoption instead of maintaining lending instances with limited activity.
For users, deprecation would change what these markets can do. New assets would no longer be supplied, and existing assets could no longer function as collateral on the Polygon and Unichain deployments. Existing users would need to withdraw assets or migrate positions to other supported Compound deployments. That is not a dramatic shutdown of the full protocol, but it is a clear narrowing of available surfaces. The practical message is migrate or wind down, because these Comets are being steered away from new lending activity.
Low usage turns into a security and efficiency argument
Gauntlet’s analysis framed low engagement as more than a growth disappointment. Maintaining underused Comets adds unnecessary complexity and potential attack vectors without delivering significant value to the Compound ecosystem, according to the proposal summary. In DeFi, that tradeoff matters because idle or thinly used deployments still require monitoring, parameter management and security attention. The strongest rationale is risk reduction, since a smaller active footprint can make it easier for governance, contributors and risk managers to focus on deployments where users are actually participating.
The decision also reflects a wider optimization pattern across decentralized finance. Protocols that once expanded across networks to capture growth are increasingly pruning markets, features and deployments that do not earn their maintenance burden. By removing the Polygon and Unichain Comets, Compound aims to reduce operational overhead, simplify smart contract architecture and direct development and security resources toward primary markets and future innovations. The proposal turns low adoption into strategic discipline, but it also leaves a familiar question for multi-chain DeFi: when does accessibility stop being useful expansion and start becoming dead weight? For Compound, the answer now appears to be measured by real usage, security focus and the willingness to sunset infrastructure that no longer strengthens the protocol as governance becomes more selective about what it actually keeps live.
