Deposit
How to deposit into a Chamber vault: connect, choose asset, sign, receive vault shares.
Depositing takes a minute or two. You connect a wallet, pick the vault, choose which asset to deposit, sign the Terms of Use, approve the token, and confirm the buy. In return you receive vault shares: your receipt token and proportional claim on the vault.
Before you start
Wallet on the right chain. Each vault lives on one chain only. You deposit from the same chain the vault is on.
Gas. You'll pay network gas for the deposit transaction (e.g. ETH on Arbitrum, POL on Polygon). Small but non-zero.
Eligibility. Public vaults accept anyone. Private vaults require your address to be on the manager's whitelist.
The flow
1. Open the vault
From the Chamber app, click into the vault you want to deposit to.
2. Click Buy
The button is labelled Buy. Buying into a vault and depositing are the same action.
3. Choose your asset
Most vaults accept a small set of deposit assets: typically USDC, and often the vault's main non-stable asset (e.g. WETH on an ETH-strategy vault). The accepted list is set by the manager via the vault's enabled assets. On HyperEVM, vaults take USDC.
Enter the amount you want to deposit. The UI shows:
The deposit value in USD (the vault's denomination asset).
Any entry fee (0–2% depending on the vault).
The estimated vault shares you'll receive.
A notice that your deposit will be locked for 24 hours.
4. Sign the Terms of Use
The first time you buy into a vault you'll be asked to sign the Terms of Use, which includes confirming you're not in a restricted location. This is an offchain message signature rather than a transaction, so it costs no gas and moves no funds.
5. Approve the token
First-time deposits of a given asset require a one-off approval transaction: you're authorizing the vault contract to pull that asset from your wallet. Sign from your wallet. Small gas cost.
6. Confirm the buy
Once approved, confirm the buy transaction. The app labels these last two steps 1/2 Approve Buy and 2/2 Buy Now. Once mined:
Your chosen asset moves from your wallet to the vault contract.
You receive vault shares in return, proportional to your deposit minus the entry fee.
The 24-hour lockup timer starts.
After depositing
You now own vault shares. They show up in your wallet as a standard ERC-20 token with the vault's symbol. They're yours; the manager cannot move, burn, or seize them.
Your deposit is locked for 24 hours. You can't withdraw during that window. See Lockup & withdrawals for why.
Your position tracks the vault. As the manager trades and the vault's NAV moves, the value of your shares moves with it, up or down.
Common questions
Can I deposit to a private vault? Only if the manager has added your address to the whitelist. If you can't deposit, the UI tells you plainly.
Can I deposit from a different chain? No. The vault lives on one chain; you deposit on that chain. Use a bridge first if your funds are elsewhere.
What if I deposit the wrong amount? You can withdraw after the 24-hour lockup (minus any exit fee). Deposit and withdrawal fees both apply if you change your mind right after the lockup.
Is there a minimum? Some vaults set a minimum deposit. Most don't. The UI tells you if there is one.
