Staking

Cryptum SDK currently only supports staking methods for the Celo blockchain.

Staking on Celo blockchain

To stake CELO you have to follow these steps below:
  • Register your account if it isn't registered yet
  • Lock tokens
  • Vote for validator group
  • Activate your votes
To unstake you have the following steps to do:
  • Revoke active votes from validator group
  • Unlock tokens
  • Withdraw tokens
Use the transaction controller to make the following calls:
const sdk = new CryptumSdk({
environment: 'testnet',
apiKey: 'YOUR-API-KEY'
})
