Contingent pools require one data input - the observed value of the reference asset at the specified expiry time - following pool expiration to determine the payoffs for long and short position tokens. This data is provided by an oracle (a.k.a "data provider"), which is specified by the user at the time of pool creation.
DIVA Protocol has been designed to be oracle agnostic, giving users the freedom to configure the oracle according to their specific setup. This includes the option to use trusted individual accounts (an "EOA"), multisigs, existing decentralized oracle solutions like Tellor, Chainlink, DIA, as well as custom oracle smart contracts.
Refer to the Oracle Integrations section to see the available oracles that can be used for secure and trustless outcome reporting.
