Bridging Assets
Penumbra is a fully private, end-to-end encrypted blockchain built using the Cosmos stack.
This guide walks users through how to bridge assets that are within the Ethereum ecosystem into Penumbra, using a Cosmos wallet like Keplr or Leap.
What You’ll Need to Get Started
Before you begin, make sure you have the following:
Metamask Wallet Installed and funded with:
ETH - for covering gas fees
Keplr or Leap Wallet These are Cosmos-native wallets that support IBC. You’ll use either one to receive assets on the Cosmos side and route them into Penumbra.
Why Bridge to Penumbra?
Penumbra is a fully private shielded zone that enables:
Encrypted transactions
Private staking and governance
A privacy-preserving DEX with no MEV risk
Once your assets are in Penumbra, you can transact, stake, swap, or LP without revealing your wallet balances or activity.
Step-by-Step: Bridge assets from Ethereum to Penumbra
Select the Ethereum network on Metamask and approve the connection
2. Choose the Asset and Networks
Select your asset (ex. USDC) and choose the supported IBC receiving network (ex. Osmosis).
Choose Osmosis or another supported Cosmos chain as the destination network (you’ll later move this into Penumbra)
3. Connect Your Cosmos Wallet (Keplr or Leap)
Enter your desired amount, click Send and click the Set destination address button to connect your Keplr or Leap wallet.
After clicking the button to set the destination wallet, choose Keplr from the list.
4. Set Your Destination Wallet Address
Click “Set Destination Address”
Choose Keplr or Leap, or paste your wallet address
Enter your password to unlock the wallet, and finally approve the connection request.
5. Review and Confirm
Review the transfer details (amount, source chain, destination chain)
Click Confirm
6. Sign and Wait for Confirmation
Approve the transaction in Metamask
Wait for the bridge to confirm transfer
Check that the funds have been received on your Keplr or Leap wallet balance
7. Move Assets into Penumbra
Once funds are received on the Cosmos chain (e.g., Osmosis), you can transfer them into Penumbra using Prax Wallet. From there, they become shielded and private. This guide takes you through how to create your Prax wallet and bridge funds from the Cosmos to Penumbra.
Shielded Assets on Penumbra
Once your funds land in Penumbra:
They are fully shielded by default. This means that no one would be able to track your activity and what you choose to do with your assets within the network.
Your transactions, balances, and liquidity positions are end-to-end encrypted
You can stake, swap, and LP privately, without exposing any data on-chain
What Makes Penumbra Unique
Default Privacy Every transaction is encrypted
Cross-Chain Interoperability Connects to 110+ IBC chains
No opt-in privacy It’s built-in, not bolted on
TLDR: Bridge into Privacy in Minutes
Ensure you have your Metamask and Keplr or Leap wallet ready
Move USDC from Ethereum to a Cosmos wallet like Keplr or Leap
Route funds into Penumbra’s wallet, Prax Wallet, to shield them
Enjoy private staking, swapping, trading and governance
