Liquid staking has emerged as one of the most efficient ways to earn yield while maintaining flexibility in decentralized finance (DeFi). On the Sui blockchain, afSUI — the liquid staking token from Aftermath Finance — enables users to stake their SUI tokens, earn rewards, and still use their assets across DeFi applications. This guide walks you through the entire process of staking SUI, understanding key metrics, choosing validators, and unlocking the full potential of liquid staking.
Understanding afSUI and Liquid Staking
When you stake SUI through Aftermath Finance, you receive afSUI in return — a 1:1 representation of your staked SUI that continues to accrue staking rewards over time. Unlike traditional staking, where your tokens are locked, afSUI remains liquid and transferable. You can hold it, trade it, or use it in various DeFi protocols such as lending markets, yield aggregators, or liquidity pools.
This flexibility makes afSUI a powerful tool for maximizing capital efficiency without sacrificing security or reward potential.

How to Stake SUI and Mint afSUI
To begin staking your SUI tokens and minting afSUI, visit the official Aftermath Finance staking page. Ensure your wallet contains SUI tokens. If you’ve already staked natively through your wallet, there’s no need to wait for unstaking — you can migrate those positions directly into afSUI.
Key Metrics at a Glance
At the top of the staking interface, you’ll see several important indicators:
- TVL (Total Value Locked): The total amount of SUI currently backing afSUI.
- APY (Annual Percentage Yield): The estimated annual return on your staked SUI via afSUI.
- Epoch Progress: Shows how much time remains until the next network epoch. Since staking and unstaking actions are processed at epoch transitions, this timer helps you plan accordingly.
Once afSUI is minted, it’s immediately available in your wallet. You can redeem it for SUI either instantly (via liquidity pools) or during the next epoch update.
Selecting a Validator
Below the metrics section, you’ll find a validator selection dropdown. This allows you to choose which validator node will secure your stake. While every afSUI holder earns the same base APY — because all afSUI tokens are fungible — selecting high-performing validators contributes to better overall network performance and stability.
Each validator displays two key details:
- Staking APY: An estimate based on the validator’s historical uptime and performance.
- Staking Fee: An optional fee set by the validator (default is 0%). If a validator charges a 1% fee and you stake 1 SUI, 0.01 SUI goes to the validator as commission, and 0.99 SUI is used for staking.
You can only select one validator per transaction, but you’re free to spread your stake across multiple validators by making separate transactions.
Choosing reliable validators enhances network decentralization and long-term yield sustainability. Consider factors like uptime, reputation, and fee structure before committing.
Step-by-Step: Staking Your SUI
- Choose your preferred validator from the dropdown menu.
- Enter the amount of SUI you wish to stake.
- Click “Stake”.
Within seconds, afSUI tokens representing your staked balance will appear in your wallet. These are immediately usable across supported DeFi platforms.
All active stakes — both new and migrated — appear under the “Liquid Stakes” tab in the staking modal. From here, you can monitor performance, manage positions, or initiate unstaking when needed.
Migrating Existing Staked SUI
If you already have SUI tokens staked natively through your wallet (e.g., via Sui Wallet or other interfaces), you don’t need to wait for the current epoch to end. Aftermath Finance supports direct migration.
Scroll to the bottom of the staking page and click on the “Native Staked” tab. Here, you’ll see all your active native staking positions.
To convert them:
- Click “Re-stake as afSUI” on any existing position.
- Confirm the transaction in your wallet.
Your native stake is seamlessly transferred into the liquid staking pool, and afSUI is minted instantly — giving you full liquidity and continued reward accrual.
