Overview: The Two Ways to Deposit to Your Solid Card
Looking to transfer USDC to your card or top up your Solid Card balance? This guide covers both, whether your USDC is already in Solid or sitting in an external wallet like MetaMask or Coinbase.
You can deposit funds onto your Solid Card using:
From Wallet / Savings (Fuse assets)
From External Wallet (any compatible network)
The key difference is where your funds are located before depositing.
Option 1: Deposit from Wallet / Savings (Fuse assets)
This is the fastest and simplest way to fund your Solid Card.
When should you use this option?
Use From Wallet / Savings if:
You already have soUSD inside Solid Wallet
Your funds are on Fuse (Solid’s native network)
Your assets are in Savings or your Solid Wallet
How it works
Open Solid and go to Deposit to Card
Select From Wallet / Savings
Choose the source:
Wallet
Savings
Enter the amount
Confirm the deposit
That’s it. Your card balance updates almost instantly.
Important note about soUSD
If you already hold soUSD, this is the recommended path.
soUSD is Solid’s native savings asset, designed to earn yield and move seamlessly across the app, including the card.
Option 2: Deposit from an External Wallet (Any Compatible Network)
This option is for users who hold crypto outside of Solid.
When should you use this option?
Use From External Wallet if:
Your USDC is in MetaMask, Rabby, Coinbase Wallet, etc.
Your funds are on networks like:
Ethereum
Arbitrum
Base
Other supported chains
How it works
Open Solid and go to Deposit to Card
Select From External Wallet
Connect your wallet (MetaMask, Rabby, WalletConnect, etc.)
Choose the network and token (e.g. USDC on Ethereum)
Enter the amount and confirm
Solid will handle the rest:
Bridging
Conversion
Gas abstraction
You don’t need to manually bridge or swap.
Important: How USDC from Other Networks Becomes Card-Ready
Example scenario
You have USDC on Ethereum in MetaMask.
What happens behind the scenes
You deposit USDC from your external wallet into Solid
Solid converts it into soUSD
The funds are credited to your Savings
You can now:
Earn yield
Deposit to your card via Wallet / Savings
Why this extra step exists
The Solid Card uses Fuse-native assets
soUSD is optimized for:
Yield
Gasless UX
Fast card settlements
This design keeps the card experience simple and reliable for users.
