The custom implementation of logic supporting a particular oracle, i.e., Bitcoin Staking Oracle. For example: LBTC / BTC price feed, derived based on the number of LBTC minted and the total amount of BTC deposited into Lombard's system on the Bitcoin chain. Detailed description [here](./lombard.md).

| Feed Type | Denomination | Deviation Comes From | Complexity of Delivery |
|:----------|:-------------|:---------------------|:-----------------------|
| **Market Feed** | Mainly USD, can also be another currency i.e., ETH / BTC | Market trading | Relatively simple |
| **Contract Rate Feed** | Underlying asset i.e., ETH for Ethereum LSTs | Specified ratio changes in the smart contract | Requires understanding of edge cases and on-chain source |
| **Real World Feed** | Custom, i.e., for CESR it's a % yield from ETH staking | Custom, i.e., CESR API is updated every 24 hours | Depends on the feed, usually medium difficulty |
| **Proof of Reserve Feed** | Custom, usually USD value | Custom, usually every 24 hours from an API | Depends on the source, usually medium difficulty |
| **Protocol Native Oracle** | Custom, i.e., BTC in the case of Lombard internal Oracle | Custom, i.e., each X minutes for Lombard | Usually work-intensive |
