Smart Contracts

There are three types of contracts deployed on networks where LBTC is supported:

  • The LBTC token smart contracts: Mints and burns LBTC tokens.

  • Consortium’s governance smart contract: Reads and commits state changes related to LBTC, ensuring that all actions are transparent and verifiable on the blockchain.

  • Proxy upgrade timelock smart contract: Delays the proxy upgrades of our smart contracts by one hour. This provides an additional layer of security which enables us to take actions or cancel the upgrade if a malicious actor's activity is detected.

Smart contract audit reports are available on GitHub.
