EquityOracleFactory

EquityOracleFactory deploys EquityOracle instances with CREATE2. The salt is the hash of the full config, so the same inputs always produce the same address, and a repeat call returns the existing oracle. It keeps a mapping from stock token to oracle and emits the complete config so indexers can reconstruct every parameter. EquityOracleFactory lets you:

Deploy an oracle for a stock token from a config struct
Predict the oracle address before deploying
Look up the oracle registered for a stock token

Addresses per network. Every address is also on Addresses.

The source code is src/oracles/EquityOracleFactory.sol on GitHub. The ABI is /abis/EquityOracleFactory.json.

Write methods

create

function create(EquityOracleConfig calldata cfg) external returns (address oracle)

Deploys an EquityOracle for cfg or returns the existing one at the predicted address. Permissionless. Reverts with AlreadyListed if the stock token already has an oracle at a different address (a different config). The constructor may also revert with EquityOracle’s config errors.

Anyone can deploy. The oracle only matters once governance points a book at it through RiskRegistry.

Input parameters

Name	Type	Description
cfg	`EquityOracleConfig`	EquityOracleConfig struct: `stockToken`, `loanToken`, `stockFeed`, `loanFeed`, `sequencerFeed` (may be zero), `calendar`, `liveStaleness`, `loanStaleness`, `maxDarkDuration` (seconds), `darkHaircutBps`, `caBoundaryWindow`, `sequencerGrace`, `darkStartOffset`, `darkEndOffset` (seconds).

Return values

Type	Description
`address`	oracle: The oracle address.

Read methods

predict

function predict(EquityOracleConfig calldata cfg) public view returns (address)

Computes the CREATE2 address create would use for cfg without deploying. Input parameters

Name	Type	Description
cfg	`EquityOracleConfig`	The same EquityOracleConfig struct passed to `create`.

Return values

Type	Description
`address`	Predicted oracle address.

Events

OracleCreated

event OracleCreated(
    address indexed oracle,
    address indexed stockToken,
    EquityOracleConfig config
)

Fires on every successful create, with the oracle, the stock token, and the full config.

Errors

AlreadyListed

error AlreadyListed(address stockToken)

The stock token already has an oracle deployed from a different config.
