Precompiled Contracts¶
Secp256k1 Signature Recover¶
The precompiled contract is used to verify the signature of a message signed using the secp256k1 elliptic curve cryptography algorithm. It will also retrun the Tendermint address of the signer.
Verify Double Sign Evidence¶
The precompiled contract is used to verify the submitted double sign evidence, which includes the two block headers signed by the same validator at different times.
Build-in System Contracts¶
Stake Hub Contract¶
The Stake Hub contract is a contract that manages the staking process, including delegation, undelegation, redelegation, and claiming rewards.
Stake Credit Contract¶
The Stake Credit contract is a template proxy contract. When a validator is created, a new stake credit contract is deployed, to manage staking credit and facilitate the exchange between credit and BNB.
Governor Contract¶
The Governor contract is a contract that manages the BNB Smart Chain governance process. It allows users to propose and vote on changes to the protocol.
Gov Token Contract¶
The Gov Token contract is a contract that manages the governance token, i.e., govBNB.
Timelock Contract¶
The Timelock contract is a contract that allows executing a time lock on some specific operations (e.g., token recovery). After the timelock period, the locked tokens can be claimed or released.
Token Recover Portal Contract¶
The Token Recover Portal contract is a contract that allows users to recover their BEP2/BEP8 tokens, which must have been bound to BEP20 tokens, after the shutdown of the cross-chaind transfer between BNB Smart Chain and BNB Beacon Chain.
