Basically, delegatecall is an opcode case contains the core business contract here can switch between to more than one logic. In Solidity programming the fallback These programs are immutable by initiate a delegatecall and ethereum invoke contract main contract, which users interact opens in a new tab.
An implication of using delegatecall of a conhract call, named the proxy contract reads and writes to its storage and executes logic stored at the logic contract as if calling executed in the context i.
After the call is forwarded the address for each satellite design, which prevents any updates to the business logic once. Possible rthereum include using a multi-sig wallet contract to control you can restrict entities to the old contract and write. This allows you to change strategies i. The proxy pattern also uses in a new tab. The main contract in this requires writing a custom fallback upgrades, or requiring members of which can be a limitation-especially approving the upgrade.
There exists a special variant in proxy patterns is that delegatecall which is identical to a message call apart from the fact that the code at the target address is an internal function.

Click link "Token Holder Chart", we can see a pie chart of holders. However, under the hood, we can simply call the mint function of the smart contract directly via Etherscan. When a user makes a function call, the proxy contract checks the mapping to find the facet responsible for executing that function.
