Depositing Into a Vault Using Arbitrum

Backing a Vault from the Arbitrum Network

tl;dr: SZN0 Vault deposits will require the use of Arbitrum-native USDC or Arbitrum-bridged USDCe

USDC vs. USDC.e

Understanding native vs. bridged

Native USDC is officially issued by Circle and always redeemable 1:1 for US dollars. Support for Native USDC was recently added to Arbitrum.

In the case of Arbitrum, there also exists a “bridged” form of USDC, known as USDC.e, that’s been bridged from Ethereum. USDC.e is not issued by Circle.

Native USDC on Arbitrum:

• Token Name: USD Coin

• Token Symbol: USDC

• Token Address: 0xaf88d065e77c8cC2239327C5EDb3A432268e5831

Bridged USDC on Arbitrum: (from Ethereum)

• Token Name: Bridged USDC

• Token Symbol: USDC.e

• Token Address: 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8

Bridging USDC(e) to Arbitrum

Head to the official Arbitrum Bridge and select USDC. Follow this very in-depth guide if you need.

You can skip to Step 2 if you already have Arbitrum network and relevant tokens added to your wallet.

It may be cheaper to bridge native ETH and later swap to USDC or USDCe!

Swapping for USDC or USDCe

If you've already bridged a different asset or want to save on gas fees by bridging ETH from Ethereum, for example, you can swap for USDC or USDCe. We recommend using Uniswap V3 on Arbitrum for this.

Here is a link that should fill out USDCe as the output. Here's one for native USDC.

If you have not already selected Arbitrum as your active network in your connected wallet, Uniswap will say it could not find the token. Swap to Arbitrum in your wallet and try the link again.

Depositing into a Vault

You can only deposit into a Vault via Arbitrum USDC.e or USDC for now.

1. Head to app.valio.xyz and connect your wallet.

   1. You can connect with the button in the top right on any page, or from any prompt window that requires it (such as "Connect wallet to deposit", visible in the next step if you haven't yet connected).

2. Find the vault you like in Explore, or from a link provided to you in the format of app.valio.xyz/vault/[vault-name].

3. Click the purple Deposit button.

4. A multi-chain vault may require an additional step of "Syncing".

5. Enter a value (minimum of $50 for now), and select either USDC.e, or USDC (native) depending on what you have on Arbitrum.

6. Approve the spend amount (required once per vault up to the limit you approve).

   1. You can either approve only the amount you're currently planning to deposit, or a larger amount that can be reached over time with future deposits. This process will vary per wallet app.

7. Once the approval has gone through, you can then Deposit.

8. That's it! You can now see your stake in the vault, the vault's positions and history, and your returns.

   1. Your fresh deposit will need to be used in a transaction by the vault manager. In the future, it will be possible to distribute your deposit into existing positions!
