Chainlink Defi Pulse Index Adapter

The adapter combines real-time DPI allocation data from on-chain with off-chain price sources in order to calculate an accurate price for the DPI.

IMPORTANT

This EA will be deprecated, set-token-index will be used for future reference. Go to Set Token Index

NOTICE

This EA will be deprecated,

As explained before, this adapter makes use of some onchain data. The current implementation is fetching data directly from SetToken contracts (https://etherscan.io/address/0x78733fa5e70e3ab61dc49d93921b289e4b667093#code). Note that this implementation won't work in other networks unless we deploy a copy of the contract.

The correct implementation should use SetProtocol.js typed library instead to fetch data directly from the SetToken contract directly. The ChainlinkAdapter.getAllocations(ISetToken _setToken) should be reimplemented in JS in order to use it.

Go to current Implementation

Configuration

The adapter takes the following environment variables:

Required? Name Description Options Defaults to
✅ ETHEREUM_RPC_URL Mainnet Ethereum RPC endpoint to get the needed on-chain data
DEFAULT_QUOTE Currency that the price will be fetched USD

Additional environment variables must be set according to the Token Allocation adapter. This composite adapter executes the code from the Token Allocation composite adapter. As such the same configuration and input parameters apply to this adapter. See ../token-allocation/README.md for more details.

Running

See the Composite Adapter README for more information on how to get started.

Input Params

Required? Name Description Options Defaults to
✅ address Address of the SetToken
✅ adapter Address of the adapter contract
name Index name
asset Asset name
