Governance Proposal Payload Format Standard

The Governance Proposal Payload Format Standard defines the exact JSON structure required to submit a valid on-chain governance action on the dYdX chain. This standard is the technical contract between governance tooling, multi-sig interfaces, and the protocol's state machine. Any tool that constructs a proposal—whether for a parameter change, a software upgrade signal, or a treasury spend—must produce a payload that conforms to this specification. A malformed payload will cause an on-chain proposal to be rejected at the time of submission, leading to governance delays and potential coordination failures.

The payload format specifies the required top-level fields, the encoding of Msg types, and the correct serialization for different proposal categories. For example, a ParameterChangeProposal requires a nested array of parameter key-value pairs with precise denomination formatting, while a SoftwareUpgradeProposal must include the exact plan name and block height. The standard also defines how to handle optional fields like description and deposit amounts, ensuring that proposals meet the minimum deposit threshold to enter the voting period. Integrators must be aware that the chain validates this structure against the gov module's expected schema, and any deviation results in a failed transaction.

For teams building governance dashboards, multi-sig coordinators, or automated proposal scripts, this standard is the authoritative source for payload construction. The operational risk of an invalid proposal is not just a failed transaction; it can freeze a governance process during a time-sensitive upgrade or risk adjustment. Chainscore Labs can validate proposal payloads against the canonical format before submission, review governance tooling for payload correctness, and help teams build robust proposal-construction pipelines that prevent submission errors.

The Governance Proposal Payload Format Standard defines the exact structure for encoding a governance action into a transaction that the dYdX chain can decode, validate, and execute. This standard is the critical interface between a human-readable governance proposal and the state-machine logic that enacts it. A proposal to change a market's maintenance_margin_ratio or to signal a software upgrade at a specific block height is not submitted as a text document; it is submitted as a serialized protobuf message containing a specific MsgSubmitProposal with a nested Content field. The Content field itself is a oneof that discriminates between action types, such as ParameterChangeProposal, CommunityPoolSpendProposal, or SoftwareUpgradeProposal.

Each action type requires a precise set of fields. A ParameterChangeProposal, for example, must contain a list of ParamChange objects, each specifying the subspace, key, and value of the parameter to be altered. The value must be a JSON-encoded string that matches the expected type for that parameter in the x/perp, x/clob, or x/staking modules. An incorrectly formatted value string will cause the proposal to fail during execution, even if it passes the governance vote. For a SoftwareUpgradeProposal, the payload must include the exact name of the upgrade handler and the height at which the chain should halt, requiring validators to coordinate their node upgrades. Constructing this payload manually is a high-risk operation; a single type mismatch or an incorrect subspace identifier can result in a permanently rejected proposal or, worse, an unexpected state change.

The operational impact of this standard falls squarely on governance tooling, multi-sig interfaces, and any protocol builder authoring a DIP. These actors must transform a governance intent into a valid, signed transaction that broadcasts to the gov module. This requires deep knowledge of the dYdX chain's protobuf definitions and the current state of on-chain parameters. A proposal to adjust the funding_rate_clamp in the x/perp module, for instance, must reference the exact parameter key as defined in the module's source code and provide a value that is within the acceptable bounds enforced by the module's validation logic. Chainscore Labs can de-risk this process by providing pre-submission validation of proposal payloads, ensuring the encoded action matches the governance intent and will execute correctly against the target chain state.
