Chronicle Protocol Contracts​

Scribe​

Scribe is an efficient Schnorr multi-signature based Oracle. Its Chronicle’s new Oracle version enabling more than 60% gas savings.

Self-Kisser​

Chronicle oracle’s read functions are protected by a whitelist.

However, via the SelfKisser contract you can whitelist (we call it kiss) yourself permissionless.

How to kiss yourself (ie msg.sender)?

$ cast send 0x0dcc19657007713483a5ca76e6a7bbe5f56ea37d "selfKiss(address)()" <oracle address you want you use>

Verify you are whitelisted (returns 1 ie true if whitelisted) :

$ cast call <oracle address> "tolled(address)" <your address>
0x0000000000000000000000000000000000000000000000000000000000000001

For more info, see the SelfKisser repo:

The IChronicle Interface - or how to read Chronicle Oracles?​

The easiest way to read the oracle is…. read() returns (uint).

$ cast call 0xc8A1F9461115EF3C1E84Da6515A88Ea49CA97660 "read()(uint)"
1656870000000000045440
