Changelog Chainlink Core

2.23.0 - PREVIEW

added

• #16789 4ce1a16 - Support new report type 'evm_streamlined'. #added
  This new report type is designed to be as small and optimized as possible to minimize report size and calldata.
  Reports are encoded as such:
  (no FeedID specified in opts)

  <32 bits> channel ID
  <64 bits> unsigned report timestamp nanoseconds
  <bytes>   report data as packed ABI encoding
  

  (FeedID specified in opts)

  <256 bits> feed ID
  <64 bits> unsigned report timestamp nanoseconds
  <bytes>   report data as packed ABI encoding
  

  Report contexts are encoded as such:

  // Equivalent to abi.encodePacked(digest, len(report), report, len(sigs), sigs...)
  // bytes32 config digest
  // packed uint16 len report
  // packed bytes report
  // packed uint8 len sigs
  // packed bytes sigs
  

  See report_codec_evm_streamlined_test.go for examples.

• #16825 390c02c - Implement support for TimestampedStreamValue data types in LLO (RWAs) #added
  Support encoding into evm_abi_unpacked or evm_streamlined report formats.
  ABI must specify how to encode both types, as such:

  // Encodes the timestamp as uint64 and data payload as int192
  {
    "abi": [[{ "type": "uint64" }, { "type": "int192" }]]
  }

  The first element of the array encodes the timestamp, the second encodes the data payload.
  Users may suppress one or the other entirely by using the special keyword "bytes0" e.g.

  // Encodes only the data payload
  {
    "abi": [[{ "type": "bytes0" }, { "type": "int192" }]]
  }
