Earn vs Vault: Which Product Is Right for You?

Introduction

The platform offers two yield products that look superficially similar — you deposit assets, you earn yield — but they're built around fundamentally different trade-offs. Earn is the conservative, flexible option: low risk, no lock-up, and yield denominated in the asset you deposited. Vault (MLP) is the higher-yield option: USDC only, with a 4-day lock and exposure to platform trading activity in exchange for a share of fee revenue.

Most users get confused not by either product individually, but by which one fits their situation. This guide is a practical decision framework: a clear side-by-side, the questions to ask yourself, and a couple of common scenarios mapped to the right answer.

1. The Five Differences That Actually Matter

Reading them in this order builds the mental model from the ground up.

Lock-up

  • Earn: none. Withdraw the full balance any time, instantly.
  • Vault: 4 days. Once deposited, USDC cannot be withdrawn until the 4-day window completes. If you make an additional deposit during the lock-up period, the unlock time for your entire balance resets to the time of the latest deposit.

Risk profile

  • Earn: low. Yield is sourced primarily from lending activity. Counterparty and platform risk exist but are limited; there is no structural drawdown mechanism for depositors in normal conditions.
  • Vault: moderate. Vault depositors share in platform revenue and in the platform's exposure to extreme market events. In rare conditions, the vault can experience temporary drawdowns before fee revenue catches up.

Yield level

  • Earn: lower. The price of full liquidity and lower risk is a more modest APY.
  • Vault: higher. The 4-day lock and acceptance of activity-linked exposure are what make the higher yield possible.

Supported assets

  • Earn: 5 supported assets — including BTC, ETH, SOL, USDC, and USDT. Yield is paid in the same asset you deposited (coin-denominated).
  • Vault: USDC only. The vault is fundamentally a USDC-denominated liquidity pool.

What you actually own

  • Earn: a deposit. Your principal is held in a flexible yield product; the yield accrues alongside it.
  • Vault: a share of MLP. You're a liquidity partner — economically participating in the platform's trading economics over the period you're deposited.

2. The Decision Tree, in One Page

Ask yourself these four questions, in order:

Question 1 — Will I need this money in the next 4 days? If yes → Earn. No further questions. If no → continue.

Question 2 — Is the asset I want to deposit USDC? If no (e.g., it's BTC, ETH, or SOL) → Earn. Vault is USDC-only. If yes → continue.

Question 3 — Am I comfortable with variable yield and possible short-term drawdown in exchange for a higher rate? If no → Earn. It's the more conservative product, and that's by design. If yes → continue.

Question 4 — Do I value full optionality (instant withdraw) over the higher Vault yield? If yes → Earn. If no → Vault is the better fit.

That's it. Most users land on Earn for at least some portion of their balance. A subset of users with USDC they're confident leaving alone for at least 4 days, who are comfortable with the risk-return profile, choose Vault for the rest.

3. Common Scenarios, Mapped

Five real situations and the natural answer for each:

  • "I have USDC sitting between trades, and I might need it on short notice."Earn. Full liquidity is the entire point. Vault would lock you out exactly when you need to act.
  • "I'm holding BTC for the long term and won't be touching it for months."Earn. Vault doesn't accept BTC. Earn pays BTC-denominated yield, which compounds your existing long position.
  • "I have $10,000 USDC I'm definitely not deploying for at least a month."Vault is a reasonable choice. The 4-day lock is well within your time horizon, and the higher yield meaningfully exceeds Earn's USDC rate over time.
  • "I want to start earning yield on my crypto but I'm new and a bit cautious."Earn. It's the more conservative product across every dimension. Once you're comfortable with the platform, you can always graduate part of your USDC into Vault later.
  • "I have a mix — some USDC I'll trade with, some USDC I won't touch, plus some BTC and ETH I'm holding." → A blend. Active USDC and the BTC/ETH go into Earn. The "definitely won't touch" USDC can go into Vault. Most experienced users do exactly this — Earn handles their working capital, Vault handles their deployable USDC reserve.

4. Can You Use Both at the Same Time?

Yes — and for many users, that's the right answer.

Earn and Vault aren't competing for the same dollar; they're built for different roles. A reasonable allocation might look like:

  • Working balance (capital you may use as trading collateral or for opportunistic positions): in Earn, in the relevant asset.
  • Long-term holdings (BTC, ETH, SOL you're keeping for months or years): in Earn, generating coin-denominated yield on top of your price exposure.
  • Locked-aside USDC reserve (capital you've consciously set aside, comfortable leaving for at least 4 days): in Vault, accepting the higher yield in exchange for the lock and the activity-linked exposure.

The discipline is to be honest about which capital actually fits each role. Vault is not a place to put money "in case nothing happens for 4 days" — it's a place for capital you've made a conscious decision to commit. Earn is the default home for everything else.

Earn is a flexible investment product supporting five assets: BTC, ETH, SOL, USDC, and USDT. It has no lock-up period, allows for instant deposits and withdrawals without affecting the principal, and carries low risk. Vault provides liquidity to the platform, supporting only USDC. It has a 4-day lock-up period (subject to real-time display on the page and final system settlement) and may offer higher returns, but the principal is at risk. Please choose a product that suits your risk tolerance.

5. Quick Recap

The four ideas worth taking with you:

  • Earn = no lock-up, lower risk, lower yield, 5 assets supported, coin-denominated. It's the flexible default.
  • Vault = 4-day lock, moderate risk, higher yield, USDC-only. It's a deliberate commitment in exchange for a premium return.
  • The decision tree: need it in 4 days? Not USDC? Risk-averse? Want full liquidity? — any "yes" sends you to Earn. Only USDC you're sure about for at least 4 days, with a tolerance for activity-linked exposure, fits Vault.
  • Most users are best served by using both. Earn for working and long-term holdings; Vault for capital you've consciously set aside.

Risk Disclosure

Both Earn and Vault are yield products with real risks. Earn carries counterparty and platform-related risks tied to lending activity; Vault carries those plus exposure to platform trading activity, including the possibility of temporary drawdowns in extreme market conditions. Yields are variable and historical APYs do not guarantee future returns. Locked deposits cannot be withdrawn during the lock-up window. The mechanics described here reflect current platform parameters and may be updated; always check the official documentation before depositing. Only deposit capital you can afford to lose.
