Then choose your role.

Clear, Cardano-specific information for ADA holders who want to stake, participate in governance and keep control of their assets.

01

What is Cardano?

Cardano is an open-source proof-of-stake blockchain designed through peer-reviewed research and evidence-based engineering. Its native asset is ADA, which is used for transactions, staking and participation in on-chain governance.

02

How does Cardano Proof of Stake work?

Cardano uses the Ouroboros proof-of-stake protocol. ADA holders can delegate the staking power attached to their ADA to a stake pool. Pools that are selected as slot leaders produce blocks and help maintain the ledger.

Important distinction

Cardano delegation does not lock ADA in a smart contract. Your ADA stays in your wallet and remains spendable.

03

What does delegation mean?

Delegation assigns your stake weight to a pool without transferring ownership. It is Cardano's way of allowing every ADA holder to support network security without operating a server around the clock.

How to delegate to 300

  1. 1
    Use a Cardano wallet

    Open 300 Wallet or a compatible browser wallet such as Lace or Eternl.

  2. 2
    Choose 300 SPO

    Use the delegation button or search with the verified 300 pool ID.

  3. 3
    Review and sign

    Your wallet shows the on-chain delegation certificate before you approve it.

  4. 4
    Remain in control

    Your ADA stays liquid and your delegation can be changed at any time.

05

How do Cardano rewards work?

Rewards come from transaction fees and monetary expansion. They are calculated by the protocol and distributed after pool costs and margin. Results vary with stake, pool performance, protocol parameters and the random slot-leader schedule.

The first rewards normally require multiple epochs. Afterwards, rewards can arrive every epoch (approximately five days) when the pool produces blocks. Rewards are estimates, not guarantees.

06

Why delegate to 300?

300 is built around proof rather than promises. Pool status, stake, delegators, block production and governance delegation are shown from public Cardano data.

  • Registered, publicly verifiable stake pool
  • Independent contribution to Cardano decentralization
  • Transparent pool parameters and live metrics
  • Non-custodial delegation
  • Integrated SPO and DRep education
  • Supported by Midnight and RealFi

What is a Cardano DRep?

A Delegated Representative votes on governance actions using voting power delegated by ADA holders. Stake-pool delegation and DRep delegation are independent: you can support one SPO and choose a different DRep without moving your ADA.

Cardano FAQ

Answers before you delegate.

Is Cardano a Proof-of-Stake blockchain?+

Yes. Cardano uses Ouroboros, a proof-of-stake consensus protocol developed through peer-reviewed research.

Does my ADA leave my wallet when I delegate?+

No. Delegation assigns staking power through an on-chain certificate. Your ADA remains in your wallet and spendable.

Is there a lock-up period or slashing?+

No. Cardano delegation has no lock-up and delegated ADA is not slashed. A pool that underperforms may simply earn fewer rewards.

When can staking rewards begin?+

A new delegation passes through the Cardano snapshot and reward calculation cycle. Initial rewards normally take several epochs; subsequent rewards can arrive every epoch when the pool produces blocks.

Can I delegate to an SPO and a DRep at the same time?+

Yes. Stake-pool delegation and governance delegation are separate. You can support 300 SPO, choose 300 DRep, or select different operators for each role.

Are the displayed rewards guaranteed?+

No. Reward amounts vary with stake, pool performance, protocol parameters, fees and the probabilistic block schedule.
