Invite-only — Volta90 is not open deposit. Your wallet must be on the vault whitelist (isAllowed) before you can mint VLT90.

​
Request whitelist access

Submit a signed access request from app.volta90.trade (Arbitrum). No gas — you authenticate with an off-chain wallet signature, same pattern as Terms acceptance.
Prepare before you apply — Use a wallet that already holds Arbitrum ETH (for gas on your first mint) and USDC (for your intended deposit). The whitelist request is signature-only — no gas. Minting after approval is on-chain.
1

Connect your wallet

Connect your wallet on app.volta90.trade and switch to Arbitrum.
2

Open Request access

If you are not whitelisted yet, the mint form shows Request access instead of Mint — open it.
3

Read how the vault works

Read Mint & redeem (async settlement, weekly cadence, no instant liquidity) — you confirm that in the signed message.
4

Sign & submit request

Your wallet signs a short message; the app records the request as pending.
5

While pending

One request per wallet — no need to submit again. Join the Telegram group for updates.
6

Review & on-chain approval

The team reviews off-chain; when approved, your address is whitelisted on-chain — the app then unlocks Mint.
What you sign — A fixed multi-line message (v1.1) that states you request access, name the vault and your address, acknowledge how the vault works, and include a timestamp. The API verifies the signature matches your address before storing the request.
Approval is on-chain only — A request stays pending until isAllowed(yourAddress) is true on the vault contract. The app and admin queue sync that check automatically — there is no manual “mark approved” shortcut.

​
After approval

Once whitelisted on-chain, return to the app — the deposit form unlocks. Follow the full mint path:
  • Rainbow-compatible wallet on Arbitrum (bridge USDC if needed)
  • ETH dust for sequencer fees
  • Accept Terms (wallet signature) on first mint if prompted
  • Approve USDC, then requestDeposit — see Mint & redeem → Deposit
Epoch Timing — Your deposit is processed at the next epoch close (weekly — see Epoch & Settlement for UTC). After submitting, there is nothing else to do until settlement completes — VLT90 is then claimed to your wallet automatically via claimSharesOnBehalf. To opt out for a given settlement (e.g. tax lot control), email hello@volta90.trade at least 48 hours before that epoch close.

​
Eligibility checklist

  • Comfortable custodying wallets + signing Lagoon flows
  • Accept epoch illiquidity (≤ 7-day rotation)
  • Aware of leveraged multi-asset path risk — not passive yield farming
  • Light KYC/KYB if the team prompts you during review
