# Oracle Module Navigate the retired EVM Oracle API and the native interfaces for exchange rates, voting parameters, and price observations. **Source:** `paxeer-network/precompiles/oracle/oracle.go`, `modules/oracle/`, `wasmbinding/queries.go`, and `node/app.go`. ## EVM price queries are retired The Oracle precompile remains registered at `0x0000000000000000000000000000000000001008`, but both `getExchangeRates` and `getOracleTwaps` revert with: ``` oracle precompile is retired; oracle data queries are disabled ``` For EVM applications, choose an active price-data integration for your network and configure its asset identifiers, units, and freshness checks. ## Native Oracle interfaces The native Oracle module handles validator voting, aggregation, and queries. It also provides the keeper used by CosmWasm Oracle query plugins. | Component | Function | | --- | --- | | `modules/oracle/handler.go` | Feed-consent delegation and aggregate exchange-rate vote messages. | | `modules/oracle/abci.go` | Vote-period processing, ballot aggregation, exchange-rate updates, and penalty-window processing. | | `modules/oracle/keeper/` | Stored rates, vote targets, validator voting state, parameters, and query services. | | `modules/oracle/client/cli/query.go` | Native exchange-rate, snapshot, TWAP, parameter, feeder, and vote-penalty queries. | | `wasmbinding/queries.go` | Native `exchange_rates` and `oracle_twaps` custom-query handlers. | Query current vote targets and observations to identify the denominations available on your network. Check observation timestamps before using a rate in application logic. ## Aggregation and parameters The native block handler builds voting claims from bonded validators, organizes ballots by configured vote targets, applies threshold checks, and derives exchange rates through weighted-median processing. Vote-period and penalty-window behavior is controlled by module parameters. Read the live parameters and vote targets before interpreting a network's observations or validator obligations. Do not infer a fixed voting period, reward band, slash rate, or required asset list from an example or another network's settings. ## Native query commands These commands are registered by the native module. Point the CLI at the Cosmos RPC endpoint for the node you are inspecting: ``` paxd query oracle params paxd query oracle vote-targets paxd query oracle exchange-rates paxd query oracle exchange-rates "$DENOM" paxd query oracle twaps "$LOOKBACK_SECONDS" paxd query oracle vote-penalty-counter "$VALIDATOR_ADDRESS" ``` The optional denomination belongs to `exchange-rates`; there is no separate singular `exchange-rate` command in this CLI. Validator operator addresses use the `paxvaloper` prefix. ## CosmWasm query boundary The `oracle` custom-query route still calls the native module handler. A CosmWasm custom querier payload for retained exchange rates has this shape: ``` { "route": "oracle", "query_data": { "exchange_rates": {} } } ``` Issue this query from a CosmWasm contract through [WASM bindings](https://docs.paxeer.app/wasmbinding). Check the returned denominations and observation freshness before using the results. ## Related interfaces - [Current precompile addresses and ABI behavior](https://docs.paxeer.app/precompiles) - [Native REST and gRPC interfaces](https://docs.paxeer.app/rest-grpc) - [Custom CosmWasm queries and messages](https://docs.paxeer.app/wasmbinding)
