A permanent read-only proxy to the latest AddressResolver instance.
\nCreate and maintain a read-only proxy to the latest AddressResolver instance. Third party contracts can then reference this proxy in their code and rest assured that thier code will work with future versions of the AddressResolver.
Synthetix is a protocol that iterates fairly frequently. Yet we want to provide an immutable avenue for that third party contracts to connect with our infrastructure, even after upgrades.
\nTo create a minimal version of Proxy, called ReadProxy, that forwards non-mutable calls to the underlying target and returns its results (transacting to mutated functions will fail).
The owner of this ReadProxy will be the ProtocolDAO and is the only one that can change the target of this proxy. The target will change only when a new version of the contract is released.
The ReadProxy will conform to the current IAddressResolver interface, which is:
interface IAddressResolver {\n\n function getAddress(bytes32 name) external view returns (address);\n\n // Note ⚠️⚠️⚠️: This is coming in the Altair (v2.22) release of Synthetix\n function getSynth(bytes32 key) external view returns (address);\n\n function requireAndGetAddress(bytes32 name, string calldata reason) external view returns (address);\n\n}\nWhile we could simply reuse the Proxy contract, it's much more powerful than is necessary here, so we propose a simpler and safer read-only version of the proxy for this instance.
AddressResolver is invoked on this ReadProxy instance, it forwards the request to the AddressResolver and returns its responseReadProxy's ABI directly) is attempted, the transaction will failtarget of ReadProxy changes, it emits a TargetUpdated event.See commit b015b8f5 and corresponding PR #512
