Overview
Stake Pool Delegation is the official Cardano Foundation guide to delegating ADA on Cardano. It explains how ADA holders can participate in network consensus and earn staking rewards by assigning their stake to a stake pool, without giving up custody of their funds. The resource covers the fundamentals of stake, delegation mechanics, incentive design, and provides a comprehensive FAQ addressing pool selection, performance metrics, saturation, and reward calculation.
Cardano uses the Ouroboros proof-of-stake consensus protocol, which selects stake pools to produce blocks based on the amount of stake delegated to them1. This design replaces the energy-intensive mining process used by proof-of-work blockchains with a system grounded in mathematical proof and game theory. Delegation is the mechanism that makes this possible, allowing any ADA holder to contribute to network security without running infrastructure.
The guide is maintained on cardano.org and available in five languages. It links to companion resources including the staking rewards calculator, a wallet directory, and pool monitoring tools for comparing stake pools before delegating.
Key Features
-
Non-custodial, liquid staking. ADA never leaves the delegator's wallet. There is no lock-up period and no slashing risk, so funds remain fully accessible at all times2.
-
Automatic reward compounding. Staking rewards accrue directly to the delegator's reward account, increasing the delegated stake each epoch without any manual action required.
-
Saturation-based decentralization. The protocol incentivizes stake distribution across many pools by reducing rewards for oversaturated pools, encouraging delegators to spread their stake1.
-
Monte Carlo reward calculator. The official staking calculator uses live mainnet data and simulation to estimate rewards, and supports side-by-side comparison of up to three stake pools3.
-
Comprehensive pool selection guidance. The FAQ covers performance metrics, desirability scoring, pool ranking, fees, uptime, and community-driven factors to help delegators make informed choices.
What to Expect
Getting started with stake pool delegation requires a compatible wallet. After setting up a wallet and funding it with ADA, delegators select a stake pool through the wallet interface or by researching pools on stake pool explorers. The delegation takes effect after a short delay of two epochs, during which rewards from any previous delegation continue.
Rewards appear automatically at the end of each epoch. The process requires no technical expertise and no ongoing maintenance. Delegators can re-delegate to a different pool at any time, with the change taking effect after the epoch transition period. Some wallets support splitting delegation across multiple pools for further diversification.
For those interested in deeper involvement, Intersect and the Cardano Developer Portal provide documentation on operating a stake pool, covering prerequisites, security practices, and available tooling for stake pool operators.
