内置合约

Conflux introduces several built-in internal contracts for better system maintenance and on-chain governance. Now Conflux has seven internal contracts. These contracts provide solidity interfaces defined here. These function can only be called via CALL or STATICCALL operation. Using operation CALLCODE or DELEGATECALL to interact with internal contracts will trigger an error.

AdminControl contract, SponsorWhitelistControl contract and Staking contract are introduced from the beginning.

ConfluxContext, PoSRegister, CrossSpaceCall are introduced at v2 hard-fork,

ParamsControl is introduced at v2.1 hard-fork.

The addresses of these 7 internal contracts are list as follows:
