Upgradability
The contract upgrade mechanism is a fundamental feature of the FBTC project, allowing the system to evolve and improve over time without disrupting existing operations. By leveraging proxy contracts and a well-defined upgrade process, FBTC ensures that contract upgrades can be implemented smoothly and securely.
Upgradability
FBTC achieves on-chain logic through a combination of proxy contracts and implementation contracts:
Proxy Contract: This is the contract with which users and other system components interact. All data is stored in the proxy contract.
Implementation Contract: This contract contains the core logic but does not store any data.
FBTC uses the OpenZeppelin TransparentUpgradeableProxy contract to enable contract upgradability. During an upgrade, the proxy contract points to the newly deployed implementation contract without changing the proxy contract's address.
