Receiving Funds

Every time you receive funds with Fluidkey, these funds are sent to a fresh address that is not linked to your main address.

With Fluidkey, you can receive and manage ETH, USDC, and any other ERC-20 token.

How to start receiving funds

When clicking on the Receive button in your dashboard, you have two options to receive funds: a private ENS address and a private hex address.

Private ENS

How it works

When you sign up to Fluidkey, you automatically get assigned two ENS addresses.

An ENS is a human-readable address you can use to receive funds. This ENS can be pasted into the to or the address field of a compatible wallet to send payments to your Fluidkey account. Every time your ENS is queryied, it resolves a new empty Fluidkey address to the wallet. This way you can receive funds without compromising your privacy.

The ENS ends with fkey.id and can also be used as a shareable web link to a page that gives senders two simple options to transfer funds to your Fluidkey account:

• Sending funds directly to a stealth address of yours

• Sending funds via Daimo Pay, which allows users to transfer from a large number of sources, including non-EVM chains like Solana and Bitcoin and fintech platforms like Revolut, Cash App, and Venmo. These transfers will be converted to USDC on Base by default but you can change the destination chain by adding a ?chain= parameter to the URL (valid values are eth, arb, op, pol).

The payment page linked to the fkey.id ENS.

Your username can also be used as an ENS address with fkey.eth, this may be compatible with more wallets and can be pasted into the to or address fields to send payments to your Fluidkey account.

Not all wallets are compatible with ENS addresses across chains.

Edit your ENS

You can easily customize the username linked to your ENS: just go to the Account section and click on Edit username.

Private addresses

In the Receive section, you will also see a hexadecimal Ethereum address and a QR code. This address is also a Fluidkey address only you control. You can use it as another option to receive funds.

Every time you press the Refresh one-time address button, a new hex address is generated.

We recommend using such a hex address only for one transfer in order to protect your privacy.

Receiving funds on Fluidkey vs other wallets

Other wallets

The status quo

With most wallets, you have one or few addresses, making it easy for external observers to track your transaction history and assets.

Fluidkey

Fluidkey ensures new funds received are not linked to your existing assets and onchain history

With Fluidkey, a new address that only you can control (i.e. self-custodial) is used to receive funds for every transfer.

This protects your privacy, as external observers cannot connect these addresses and cannot link them to your main address.
