dyn_entry

The decorator @dyn_entry on a function indicates that said function should be made available as a dynamic entrypoint of the smart contract. For more information about dynamic entrypoints, see Dynamic entrypoints.

Dynamic entry points can be removed or updated without deploying a new contract, unlike entrypoints decorated with @entry, which cannot be modified after the contract is originated. Dynamic entrypoints can be used for example to implement a DAO (Decentralized Autonomous Organization) with a built-in update mechanism that allows participants to vote on upgrades to the contract, in a manner somewhat akin to the amending process of the Tezos protocol itself.
