StargateNFT

It is a continuation of the legacy VeChain Nodes (X-Node and Eco Nodes) collection. This contract allows users to stake VET and receive an NFT in exchange, which acts as a certificate of the staked VET. Whoever owns the NFT, also owns the staked VET associated to it.

This contract also supports the claim of VTHO rewards for user stakes generated by the protocol for holding VET (aka: base rewards).

The contract uses the following protocol libraries to implement the main functionality: Clock : Current block/timestamp/clock mode helper. DataTypes : Data structures. Errors : Custom errors definitions. Levels : Levels management. MintingLogic : Core stake/unstake & migration flow. Settings : Contract-parameter management. Token : Get tokens/users tokens data helper. VetGeneratedVtho : Support dual-token VeChain economic model. Distribution generated VTH0 rewards.

StargateDelegation

Upgradeable contract that allows a user owning a StargateNFT to start delegating and accumulate delegation VTHO rewards.

The term "delegation" is used in the context of the Hayabusa protocol hardfork, when a user will delegate their staked VET to a validator. This contract, though, is used to simulate the delegation process, so it's not used in the Hayabusa protocol, and VET are not transferred. When a user starts delegating, the contract will lock the NFT (done in the StargateNFT contract by calling the isDelegationActive function) and start accumulating rewards based on the NFT level. When a user exits delegation, the contract will unlock the NFT and stop accumulating rewards.

Each delegation follows a delegationPeriod, and it serves two main purposes:

It defines a mandatory minimum duration for delegation (users can't exit before this period ends)
It creates boundaries for when rewards can be claimed (only for completed periods)

NodeManagementV3

This contract was originally created and used by VeBetterDAO to manage node ownership and delegation. It supports delegation (aka: adding another address that can use the ownership of your NFT to perform on chain actions), retrieval of managed nodes, and integration with legacy VeChain Nodes and token auction contracts.

Developers can use this contract to easily migrate from pointing to the legacy VeChain nodes contract to the new StargateNFT contract, by pointing to both the legacy VeChain nodes contract and the new StargateNFT contract, allowing an easy way to check node ownership and delegation for both.
