Earn

Automatically earn yield on your funds in Fluidkey.

Fluidkey auto-earn allows you to earn yield on selected tokens as soon as they are added to your account. This feature is currently available on USDC on Base. More tokens and chains will be supported in the near future.

How to enable and disable the feature

To enable auto-earn, click the auto-earn toggle at the top right of the Funds section in your dashboard. You will be asked to input your PIN to confirm the action.

You can disable the feature at any time by clicking the amount earned at the top right of the Funds section in your dashboard. You will also be asked to input your PIN to confirm the action.

Audits

The Fluidkey Earn module has successfully undergone a security audit by Ackee. You can find the audit report here.

Yield source

This feature uses Morpho under the hood. Morpho is a battle-tested lending protocol that has undergone over 25 audits to date.

Currently, Morpho pools curated by Gauntlet have been selected for this feature. Gauntlet is a crypto firm that specializes in providing risk management and financial modeling for defi protocols.

More specifically, the following Morpho lending pools are currently being used for this feature:

Name	Chain	Address	Min. Amount
Gauntlet USDC Prime	Base	0xeE8F4eC5672F09119b96Ab6fB59C27E1b7e44b61	$1
Gauntlet EURC Core	Base	0x1c155be6bC51F2c37d472d4C2Eba7a637806e122	$1
Gauntlet WETH Core	Base	0x6b13c060F13Af1fdB319F52315BbbF3fb1D88844	$1
Gauntlet cbBTC Core	Base	0x6770216aC60F634483Ec073cBABC4011c94307Cb	$1

As we expand this feature to more tokens and chains, the list of yield protocols and pools used will be updated in this section. We will only add protocols and pools that have been thoroughly audited and are battle-tested.

How it works

When auto-earn is enabled, the stealth addresses generated for your account will have the Fluidkey Earn module enabled with the abovementioned lending pools.

This allows Fluidkey to automatically move funds on behalf of your stealth addresses into these lending pools when you receive them. For security reasons, the scope of the module is extremely limited, such that Fluidkey cannot move funds anywhere else than the pools listed above. Only amounts that are above the minimum amount listed above will be automatically moved into the lending pools.

You will see the amount earned from this feature in the top right corner of the Funds section in your dashboard.

In order to spend funds that are currently earning yield, no extra action is required from you. For example, when you want to send USDC on Base, you can just send USDC from your balance as usual and funds will be automatically taken from the lending pool in the same transaction.

Yield computation and fees

All amounts displayed in your dashboard are net of fees, meaning that the amount you see is the amount you can spend. The yield percentage displayed is based on the daily APY of the lending pool.

Fluidkey takes a fee of 10% on the yield generated by this feature (e.g. if you earn 4% yield, we take a fee of 0.4%) as well as any protocol rewards. The more you earn, the more we earn alongside you.
