Staking

• Cosmos supports staking. Cosmos uses a delegated proof-of-stake (DPoS) consensus mechanism. Atom holders can stake their tokens to validators.
• Validators participate in consensus to produce new blocks and validate transactions.
• By staking Atoms, holders can earn rewards.

Balances

Atom is the native asset of Cosmos. The base unit of Atom is uatom (microatom).

• 1 Atom = 1,000,000 uatom
• 1 uatom = 0.000001 Atom

To check the balance of a wallet:

Copy code block
1

3
const address = yield walletInstance.getAddress({ address: 'TTwW9apvyVL9EBqDVeTVDft15hf1Jnkpzy' });
const bal = address.balance;
return bal;

Tokens

Cosmos does not support tokens transactions.

Consolidation

We are supporting memo based addresses. Therefore, consolidation is not required.

Fee rate

The default gas fee is 0.35 uatom
