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 Epoch 1 specific vault listings and reward budgets, see Epoch 1 Details.

​
How It Works

When you deposit through Ethereum vaults, your assets are automatically:
  1. Bridged to Neutron via secure cross-chain infrastructure
  2. Deployed to eligible DeFi protocols (Amber lending, Supervaults LP)
  3. Earning rewards from both DeFi yields and NTRN campaign incentives
Simple lending vaults and rewards can be fully managed through an EVM wallet, whereas LP strategies require a Neutron wallet to withdraw LP tokens. For detailed cross-chain coordination, see Address Linking System.

​
Available Vault Categories

​
Simple Lending Vaults

Best for: Risk-averse users wanting straightforward yield and management fully through EVM wallets (deposit and withdraw)
  • Just Lend - wBTC on Amber: 100% lending on Amber Protocol
  • Just Lend - wBTC on Mars: 100% lending on Mars Protocol
  • Requirements: No KYC, no deposit caps
  • Strategy: Pure lending exposure with stable yields

​
Hybrid Strategy Vaults

Best for: Users wanting diversified exposure
  • wBTC with LST LP: Combines lending with liquidity provision
  • Available pairs: eBTC, SolvBTC, uniBTC
  • Strategy: Split between Amber lending and Supervault LP positions
  • Requirements: No KYC required

​
maxBTC Access Vaults

Best for: Users wanting exposure to maxBTC ecosystem
  • MaxBTC Liquidity Vault: Provides liquidity to maxBTC-wBTC pool (KYC required)
  • MaxBTC Deposit Vault: Direct maxBTC holding strategy (KYC required)
  • Just LP - USDC maxBTC: USDC deposits to maxBTC-USDC pool (No KYC required)
  • Requirements: KYC only required for MaxBTC Liquidity and MaxBTC Deposit vaults

​
LST Main Vaults

Best for: LST holders wanting maxBTC exposure
  • Available LSTs: eBTC, SolvBTC, uniBTC
  • Strategy: Lend LST + provide liquidity to maxBTC-LST pools
  • Requirements: No KYC, direct LST deposits

​
Step-by-Step Process

​
1. Prepare Your Wallet

Compatible Wallets:
  • MetaMask (recommended)
  • Coinbase Wallet
  • WalletConnect compatible wallets
Required Assets:
  • Supported BTC derivatives (wBTC, eBTC, SolvBTC, uniBTC)
  • ETH for gas fees
  • USDC (for USDC-maxBTC vault only)
For LP Strategy Withdrawals: You’ll need a Neutron wallet (Keplr recommended) to receive Supervault LP tokens. Simple lending vaults can withdraw to your original wallet.

​
2. Navigate to Bitcoin Summer

Visit app.neutron.org/btc-summer to access the vault interface. Supported assets: WBTC, eBTC, solvBTC, uniBTC, and USDC Selection criteria:
  • Asset type: What BTC derivatives you currently hold
  • Risk tolerance: Simple lending vs LP strategies
  • KYC willingness: Only maxBTC vaults require KYC
  • Reward goals: Different strategies offer different yield profiles

​
3. Complete Deposit

1

Select Vault

Choose a vault from the available options (note: some may be in beta)
2

Connect Ethereum Wallet

Connect your Ethereum wallet when prompted at the bottom of the deposit modal
3

Enter Deposit Amount

Enter amount or click “Use Max” to deposit your entire balance
4

Confirm Transaction

Click the “Deposit” button and approve the transaction in your wallet
5

Monitor Position

Track your position on the Balance page or Bitcoin Summer interface

​
4. Monitor Rewards

  • Campaign Rewards: NTRN incentives based on your deposit size and duration
  • DeFi Yields: Underlying protocol rewards (lending rates, LP fees)
  • Asset Issuer Rewards: Potential additional rewards from LST issuers

​
Withdrawal Process

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

​
What You Receive

Depending on your vault strategy: Simple Lending Vaults (Just Lend):
  • Underlying assets (wBTC, eBTC, etc.) sent back to your original wallet
  • No Neutron wallet needed for pure lending strategies
LP Strategy Vaults (Hybrid, LST Main, maxBTC):
  • Supervault LP tokens (Neutron-native tokens)
  • Lending assets (underlying BTC derivatives)
  • Neutron wallet required to receive LP tokens

​
How to Find Your Positions

Depends on your vault strategy: Simple Lending Vaults:
  • Underlying assets (wBTC, eBTC) can be withdrawn back to your original Ethereum wallet
  • No additional setup needed for pure lending strategies
LP Strategy Vaults:
  • Supervault LP tokens are sent to your Neutron wallet (Neutron-native tokens)
  • Lending portions may be sent as underlying assets
  • Balance page: View positions at app.neutron.org/balance
  • Neutron interfaces: Manage LP positions through Neutron DeFi apps

​
Timing Considerations

  • No Principal Lock: Withdraw deposits anytime
  • Reward Forfeiture: Early withdrawal forfeits pro-rata epoch rewards
  • Processing Time: Depends on underlying protocol liquidity
  • Cross-chain delay: Allow time for bridging and position deployment

​
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. This requires cross-chain coordination but can significantly increase your earnings.

​
Address Linking for Boosts

Critical Rule: If you deposited using your EVM address, you must boost that same EVM address. Quick process:
  1. Set up a Neutron wallet (Keplr recommended)
  2. Acquire NTRN tokens
  3. Use the “Unlock your booster” feature on the Bitcoin Summer page
  4. Important: Select “Boost this wallet” if using the same EVM wallet, or “Link an address” to specify your EVM deposit address
  5. Lock NTRN and earn up to 3x total rewards

​
Boost Coordination

Since boosts require a Neutron wallet but your deposits are on Ethereum:
  • You’ll connect both wallets during the boost process
  • The system will help you link your EVM deposit address to your Neutron boost
  • Monitor your boost status on the Balance page
