Testnet

If you need to experiment with the StarGate contracts, we deployed a set of contracts for you.

Note to Users:

When transferring or delegating NFTs, any unclaimed delegation rewards will automatically be claimed by the contract on behalf of the user. However, the StarGate Delegation contract could fail if it runs out of VTHO. For testing purposes, please send testnet VTHO to the StarGate Delegation contract to enable other users to conduct their tests effectively.

Import the contracts on Inspector

Go to https://inspector.vecha.in/, switch to testnet (on top-right) and add the StarGate, NodeManagement and TokenAuction contracts by setting a name, the address and the ABI.

You can find the addresses above, and ABIs are available for download here.

Interact with contracts

You can test the StarGate contracts without any needed permission, just call stake() or stakeAndDelegate(). The same goes for the NodeManagement contract.

If you want to test the migration flow instead, you will need to first interact with the TokenAuction contract to mint your self a legacy Node NFT.

To mint a Node in the TokenAuction contract:

  1. Import the testnet mnemonic:

denial kitchen pet squirrel other broom bar gas better priority spoil cross

A wallet can hold only 1 TokenAuction NFT at a time.

Need VTHO? Use this faucet: https://faucet.vecha.in/

  1. Call the TokenAuction contract

await legacyNodesContract.addToken(
  holderAddress, // Put an address which does not come from the testnet mnemonic
  level, // 1 for Strength .... 7 for MjolnirX
  onUpgrade, // set this to false
  applyUpgradeTime, // set this to 0
  applyUpgradeBlockno // set this to 0
);

The lead time and trasnfer cooldown for the TokenAuction NFTs on testnet are set to 0.

There is no need to actually hold VET in your wallet in order to own a legacy NFT, it is just enough to call the addToken() function.

In testnet there is a limit of 100000 legacy VeChain Nodes that can be minted. After this number is reached, a new set of contracts must be deployed.

  1. Now, you can call migrate(), and migrateAndDelegate() functions on the StarGateNFT contract.

Run and Deploy Smart Contracts

For a comprehensive guide on executing tests, compiling the contracts, or deploying them within your own environment, developers can refer to the project repository on GitHub. This resource contains all necessary files and instructions, allowing you to clone the repository, explore the smart contract code, and follow setup procedures step-by-step.

Access the repository here: VeChain Stargate Contracts. This will equip you with the tools to effectively interact with the contracts and interface with the VeChain testnet or mainnet as needed.

Seed StargateDelegation contract with VTHO on solo network

In order to test the delegation rewards, claiming StargateDelegation contract must hold enough VTHO tokens. If you have your inspector up and running, you can add the VTHO token there like this:

Name: VTHO
Address: 0x0000000000000000000000000000456E65726779
Abi:
8KB
VTHO-abi.json

After you did it, call the transferFrom() function in the "Write" tab, with StargateDelegation contract as a recipient.
