A Simple Consensus Smart Contract library for all nodes in XYO
This package has been built to streamline the dApp build process for anyone ready to integrate XYO into their project.
Especially crucial in this library are the XyGovernance
and XyStakingConsensus
contracts.
Requirements:
- In the command line go ahead and install using
npm
npx zos link dapp-scsc-solidity
Suggestions:
- Familiarity with
- Solidity
- Web3
- Truffle
- Ganache
Requirements:
- Watch this video on staking a node in XYO
- Check out dApper
- dApper allows you to interact with the smart contracts from the scsc library on the browser
Below are the commands that we used to deploy the library to Kovan and Mainnet

Adding stake to a diviner on our network is a vital step in utilizing our network, and further understanding it.
use this hash QmaHuJh3u5J4W8WYhJnfH1yZUWWwUaehsVLbUPMEd4ymqN
with the hash
https://dapper.layerone.co/settings/QmaHuJh3u5J4W8WYhJnfH1yZUWWwUaehsVLbUPMEd4ymqN
The contract will load, giving you access to the contracts through the contract simulator.
Once you have verified that you have enough balance to stake the diviner, select the XyStakingConsensus contract This contract stores all the stake of the network
Approve the stake for the Diviner in the XyERC20 contract (make sure that you have the address for the XyStakingConsensus) using the approve()
function.
Go through metamask to submit the transaction. You have now approved stake, let's keep going.
The diviner is represented by a Stakable token
-
Mint one token with your wallet address by selecting the XyBlockProducer and the address below
-
Select the
mint()
function and paste your wallet address into thebeneficiary
field -
Confirm the transaction on metamask
This will produce one non-fungible token (ERC721). This is unique to this specific diviner.
Then select the tokenByIndex()
function and enter 0
for your token address.
Copy the token address, this is virtual id of your diviner
- Select the
stake()
function - Paste the diviner id into the stakee field
- enter an amount to stake (make sure it is in your approved limits!)
- Click
execute
note you are the staker, and the stakingId is the ledger of the stake that you have in the diviner
To check out the data of the stake, select the stakeData()
function, paste in the stakingId in the sole field.
You will now get a returned JSON object with your stake amount, the block it was staked on, the staker, and the stakee.
