Evidence Precompile

The Evidence precompile exposes the Cosmos evidence module’s read-only queries to EVM smart contracts. It lets you look up a single piece of evidence by its hash or page through all recorded evidence. Both methods are views and never mutate state.

Address

The Evidence precompile is located at the following address:

Methods

`evidence`

Returns the evidence recorded under the given hash, JSON-encoded as bytes. The call reverts if no evidence exists for the provided hash.

function evidence(bytes memory evidenceHash) external view returns (bytes memory);

Parameters

evidenceHash — the hash of the evidence to look up.

Returns

A bytes value containing the JSON encoding of the evidence (for example an Equivocation record with its @type, height, power, time and consensus address fields).

`allEvidence`

Returns all recorded evidence, paginated. Each entry in evidenceList is the JSON encoding of a single piece of evidence.

function allEvidence(bytes memory pageKey) external view returns (AllEvidenceResponse memory response);

Parameters

pageKey — the pagination key returned by a previous call. Pass empty bytes ("") to request the first page.

Returns

AllEvidenceResponse containing:
- evidenceList — an array of JSON-encoded evidence entries.
- nextKey — the pagination key for the next page, or empty bytes when the results are exhausted.

Structs

`AllEvidenceResponse`

Field	Type	Description
`evidenceList`	`bytes[]`	JSON-encoded evidence entries for the current page.
`nextKey`	`bytes`	Pagination key for the next page (empty when exhausted).
