Solo vs Pooled vs Exchange Staking: Who Holds Your Keys

The three main ways to stake — solo, pooled (delegated), and exchange — differ most in one thing: who holds your keys. Solo staking keeps everything in your control; pooled or delegated staking keeps your keys while a validator does the work; exchange staking hands custody to a company for maximum convenience. Get that custody question right and most of the other tradeoffs fall into place. This note compares the three so you can match one to your situation.

It sits alongside the fuller how-to-stake guide, which also covers liquid staking as a fourth option.

Exchange staking: maximum convenience, minimum control

With exchange staking you leave coins on a centralised exchange, opt in, and it stakes for you and credits a share of the rewards. There is nothing to install and no validator to manage — it is the easiest way to earn a staking reward. The cost is custody and fees: the exchange holds your keys (not your keys, not your coins), takes a cut of rewards that is often substantial, and exposes you to its solvency and to regulatory action. US retail staking was reshaped in 2023 when the SEC brought a case against Kraken's staking programme, which Kraken settled and closed for US customers; the Coinbase staking case was later dropped in 2025. Convenient, custodial, and dependent on the company staying sound.

Pooled / delegated staking: keep your keys, share a validator

Delegated staking is the middle path and, for most self-custodial holders, the sensible default. From your own wallet, you assign your stake to a validator on networks like Cardano, Solana, Cosmos or Polkadot; the coins never leave your custody, and you can redelegate or begin unbonding at will. You pay the validator a small commission — commonly 5–10% of rewards — and you take on its performance: downtime lowers your rewards, and on slashing networks a validator's serious fault can pass a penalty to your stake. The main job is choosing reliable validators and spreading across a few rather than piling into the largest.

Solo staking: everything yours, responsibility included

Solo staking means running your own validator: your keys, the full network reward, no middleman's cut, and a direct contribution to decentralisation. It is the lowest-counterparty-risk method — nobody can freeze or lose coins you alone hold. The price is real work and real minimums: 32 ETH per validator on Ethereum (other networks vary), plus keeping the machine online, correct and secure. Downtime costs small penalties; serious faults trigger slashing. Solo staking rewards the diligent and punishes the careless, and it is the wrong choice for anyone who will not maintain it.

How to choose

Start from custody. If you are unwilling to use a self-custody wallet at all, exchange staking is the realistic route — pick a large regulated venue, understand the fee cut, and treat the position as money you could lose to a custodian. If you already self-custody, delegated staking gives you nearly the full reward without surrendering your keys, and is the honest default for most people. If you hold a large amount for the long term and are comfortable with the technology, solo staking removes the middleman entirely. Notably, the method we most often call safest — self-custody, whether delegated or solo — pays this site nothing, and we still recommend it where it fits.

What the fee cut really costs you

The reward differences between these methods are not rounding errors, and they compound. An exchange that keeps a quarter or a third of the network reward is quietly taking a large share of your yield every year in exchange for convenience and custody; a delegated validator taking 5–10% leaves you with most of the reward while you keep your keys; and solo staking takes none, giving you the full network rate minus your own running costs. Over years, on a meaningful balance, the gap between "exchange keeps a third" and "you keep it all" is substantial. That is not a reason to solo stake regardless — the work and slashing responsibility are real — but it is a reason not to default to exchange staking purely because it is the easiest button to press.

There is also a network-health dimension that the pure self-interest math misses. When most people pick the most convenient custodial option, stake concentrates in a handful of large operators, which is bad for the decentralisation that makes these networks worth using in the first place. Delegating to smaller, reliable independent validators — or solo staking — spreads that power out. You do not have to be an idealist about it, but it is worth knowing that the convenient choice and the healthy-for-the-network choice point in opposite directions, and that the self-custody options happen to be better on both counts for anyone willing to do a little more work. The how-to-stake guide lays the full set of tradeoffs side by side.

One practical note before you decide: whichever method you choose is rarely permanent. You can start with exchange staking to learn how rewards feel, then move to delegated staking once you are comfortable holding your own keys, and only consider solo staking if your balance and skills grow into it. Treat the choice as a starting point you can revisit as you learn, not a one-way door, and let your own comfort with self-custody, not a headline yield, set the pace.

Whatever you pick, the constants hold: only stake what you can afford to lose, never treat the reward as guaranteed, and check the network's unbonding period so a lock-up never surprises you.
