Quick Start

Get started with Shinobi Cash in minutes.

Prerequisites

  • A wallet (MetaMask, Rabby, etc.)
  • Testnet ETH on Arbitrum Sepolia or Base Sepolia

Step 1: Connect Your Wallet

  1. Visit testnet.shinobi.cash
  2. Click "Sign in with Wallet"
  3. Connect your wallet and sign the authentication message

This signature derives your private keys for the privacy pool — your wallet never has direct access to your deposits.

Step 2: Make a Deposit

  1. Navigate to the Deposit tab
  2. Select your source chain (Arbitrum Sepolia or Base Sepolia)
  3. Enter the amount of ETH to deposit
  4. Review the fees and confirm
What happens:
  • Your ETH is deposited into the privacy pool
  • A commitment is added to the Merkle tree
  • For cross-chain deposits, a solver fills your intent on the pool chain

Step 3: Wait for Activation

After depositing, your funds need to be "activated" before you can withdraw:

  1. On-chain confirmation — Transaction included in a block
  2. Indexer sync — Our indexer detects your deposit
  3. ASP approval — Association Set Provider verifies compliance

This typically takes a few minutes.

Step 4: Withdraw Privately

  1. Navigate to the Withdraw tab
  2. Select a note with available balance
  3. Enter the recipient address (can be any address, any supported chain)
  4. Select the destination chain
  5. Review fees and confirm
What happens:
  • A zero-knowledge proof is generated in your browser
  • The proof verifies you own a valid deposit without revealing which one
  • For cross-chain withdrawals, a solver fills your intent on the destination chain
  • Gas is sponsored — you don't need ETH on the destination chain

Understanding Your Notes

In the Notes tab, you'll see your deposits organized as "note chains":

StatusMeaning
AvailableReady to withdraw
PendingWaiting for activation or ASP approval
SpentAlready withdrawn

Each withdrawal creates a "change note" for the remaining balance, similar to how cash transactions work.
