Best for: Users coming from Ethereum who want to participate with familiar wallets like MetaMask while accessing Bitcoin DeFi opportunities through automated vault strategies.
This guide covers the evergreen process for Ethereum participation in BTC Summer. For current Phase 1 specific vault listings and reward budgets, see Phase 1 Details.

​
How It Works

When you deposit through BTC Summer vaults, your assets are automatically:
  1. Bridged to Neutron via secure cross-chain infrastructure
  2. Deployed to eligible DeFi protocols (Amber lending (docs), Supervaults LP)
  3. Earning rewards from both DeFi yields and NTRN campaign incentives
All vault withdrawals and campaign rewards are processed on Neutron - you’ll need a Neutron wallet to receive both your NTRN campaign rewards and withdrawn assets (Supervault LP tokens, lending assets) regardless of vault strategy. For Neutron wallet setup, see our User Quickstart Guide. For detailed cross-chain coordination, see Address Linking System.
Current vault offerings change by phase. For specific vault listings, caps, and availability:

​
Step-by-Step Process

Compatible Wallets:
  • MetaMask (recommended)
  • Any EVM compatible wallet
Required Assets:
Visit app.neutron.org/bitcoin-summer to access the vault interface.
1

Select Vault

Choose the Ethereum Vaults tab (for Ethereum deposits) vs. the Neutron Positions tab. Pick a vault from the list - hovering over a vault will show the eligible deposit asset (e.g., WBTC, eBTC, uniBTC).
2

Connect Ethereum Wallet

Once you’ve selected a vault, connect your preferred Ethereum wallet to begin the deposit process
3

Enter Deposit Amount

Enter the amount to deposit or use “Max” to allocate your full balance. You can also click on the dollar value to deposit by dollar-denominated amounts
4

Confirm Transaction

Once you’ve entered an amount, confirm the transaction in your wallet extension
5

Monitor Position

Upon successfully depositing, you can view your position and any accrued rewards on the Balance page, the Bitcoin Summer Ethereum Vaults table, or on the individual vault page for the vault you deposited into
  • Campaign Rewards: NTRN incentives based on your deposit size and duration. Different activities earn 1x-6x multipliers - see NTRN Rewards Multipliers
  • DeFi Yields: Underlying protocol rewards (lending rates, LP fees)
  • Asset Issuer Rewards: Potential additional rewards from LST issuers

​
How to Withdraw

Important: Withdrawals are processed on the Neutron side. You’ll receive the underlying positions directly to your wallet, not back through the vault interface.
1

Navigate to Your Vault

To withdraw your balance from the vaults, simply navigate to a vault in which you have previously made a deposit
2

Switch to Withdrawal Mode

Toggle the setting in the top right from Deposit to Withdrawal and enter the amount you’d like to withdraw from your position
3

Confirm Withdrawal

Withdrawals from the vaults must be confirmed using your Ethereum wallet
Phase Timing: Bitcoin Summer Phases last two months, and you can view the amount of time remaining in a Phase on the Bitcoin Summer dashboard. Withdrawing your balance from a vault before the end of a Phase will cause you to forfeit your NTRN rewards.

​
What You Receive

  • Underlying assets (wBTC, eBTC, etc.) sent to your Neutron wallet
  • Campaign rewards (NTRN tokens) sent to your Neutron wallet
  • Supervault LP tokens (Neutron-native tokens)
  • Lending assets (underlying BTC derivatives)
  • Campaign rewards (NTRN tokens)
  • All sent to your Neutron wallet
Your positions can be tracked on the Balance page of the Neutron App

​
Maximize Your Rewards

Want to boost your rewards up to 3x? You’ll need to set up a Neutron wallet and lock NTRN tokens, then point the boost to your EVM deposit address.

​
Boost Your NTRN Rewards (For Ethereum Users)

You can boost your NTRN rewards during Bitcoin Summer by up to 3x by staking NTRN for up to 48 months. During your selected staking period, you’ll earn ~3% NTRN staking rewards + up to 3x boosted Bitcoin Summer NTRN rewards.
1

Access Booster Feature

To boost your rewards, click the “Unlock your booster” button on the Bitcoin Summer Ethereum Vaults page
2

Connect Neutron Wallet

You will be prompted to connect a Neutron wallet. This is the wallet that will accumulate NTRN rewards. We recommend creating one using Keplr for this step if you don’t already have a Neutron wallet
3

Link Your Wallets

You’ll be prompted to link your Neutron wallet with the EVM address that you used to deposit assets into the Bitcoin Summer vaults. Note: You must use the EVM address from which you deposited assets into the Bitcoin Summer vault
4

Stake & Lock NTRN

After linking your wallets, you can monitor your boosts by clicking “View boost overview” from the Bitcoin Summer dashboard. You can increase your multiplier by selecting the “Stake & Lock” option from the modal. Note: Make sure the Neutron chain is selected on your Neutron wallet
5

Optimize Your Multiplier

You can stake any amount of NTRN for up to 48 months to boost your rewards. Larger deposits and longer stake durations will maximize the size of your multiplier, up to 3x. Note: It can take up to 15 minutes after submitting your transaction for the multiplier to appear on the Bitcoin Summer dashboard
