What RedStone is
RedStone is an oracle ecosystem delivering frequently updated, diverse data feeds to smart contracts across chains.
It puts data on-chain differently from a push oracle: signed data packages ride the user's own transaction calldata and are verified on the fly, instead of living in expensive EVM storage.
Scope
The on-chain suite: the consumer base contracts verifying signed data packages attached to calldata, and the multi-feed adapters.
