How to Choose a Sui Validator
With over 100 active validators on the Sui Network, choosing the right one matters. Your validator choice affects your rewards, risk, and the network's decentralization. Here's what to look for.
Key Metrics to Compare
1. APY (Annual Percentage Yield)
APY tells you how much you'll earn per year as a percentage of your staked amount. On Sui, APY typically ranges from 1.5% to 3%. Higher APY is better, but it's not the only factor — a high-APY validator with poor reliability isn't a good choice.
2. Commission Rate
Validators charge a commission on staking rewards. A validator with 5% commission keeps 5% of the rewards generated by your stake. Lower commission means more rewards for you, but some commission is healthy — it funds validator operations and infrastructure.
3. Unique Stakers
The number of unique addresses staking with a validator is a strong signal of community trust. A validator with 10,000 stakers has broader trust than one with 50, even if both have similar APY. This is the most important metric in our trust score.
4. Total Stake
The total amount of SUI staked with a validator reflects institutional and whale confidence. Large stake means the validator has been vetted by sophisticated participants. However, too much stake concentration in one validator hurts decentralization.
Understanding Trust Score
On app.suistaking.io, every validator has a trust score from 0 to 100, computed from four on-chain factors:
| Factor | Weight | Why it Matters |
|---|---|---|
| Unique Stakers | 50% | Broader community trust |
| Stake Weight | 35% | Capital commitment and confidence |
| Low Commission | 5% | More rewards passed to stakers |
| APY | 10% | Current yield performance |
A score of 80+ indicates high community trust. 50-79 is moderate. Below 50 suggests the validator is newer or less established.
Best Practices
- Diversify across 2-3 validators to reduce risk
- Check the commission rate — 0-5% is common, above 10% is unusual
- Look at staker count — more stakers usually means more reliable
- Use the simulator at app.suistaking.io/simulate to compare projected earnings before committing
