Contract addresses
This page lists the deployed addresses of notable system contracts. You can see the contract code and transactions in the Block Explorers.
Some Kaia features rely on the special smart contracts called system contracts. They hold critical information such as validators and staking. A Kaia node reads the storage states of system contracts as part of its block processing job. Users and developers can interact with these contracts to query information and build applications such as staking services.

Some contracts are not directly read by Kaia nodes but play crucial roles in operating the Kaia blockchain and its ecosystem. They include treasury, governance, and KAIA token bridge contracts.
