Create a Vault

DeFindex Vaults let wallet builders design yield products tailored to their users. With a vault, you choose the assets, strategies, allocation, and fees—and you can rebalance positions or rescue funds at any time. From the end-user’s perspective, it’s just deposit and withdraw.

Step 1: Assign Vault Roles, Fees, and Upgradability

Before deployment, you must configure the following roles (each tied to an address):

  • Vault Manager – primary owner, manages settings, upgrades, and other roles (use a multisig for security)

  • Rebalance Manager – allocates funds across strategies (can be automated)

  • Fee Receiver – collects performance fees (use a secure, dedicated wallet)

  • Emergency Manager – rescues funds and pauses risky strategies (automate for faster response)

Fees

  • Fees are expressed in basis points (1 bp = 0.01%).

  • The Vault Fee is applied to strategy earnings and assigned to the Fee Receiver.

Upgradability

  • You may choose whether the vault contract is upgradable.

  • If enabled, the contract’s WASM code can be updated without user signatures.

  • This allows improvements or bug fixes without interrupting vault operations.

Step 2: Select Assets and Strategies

DeFindex offers curated and audited strategies, currently live for:

  • Blend Autocompound – Fixed Pool: USDC, EURC, XLM

  • Blend Autocompound – YieldBlox Pool: USDC, EURC, XLM

Step 3: Deploy the Vault

You can deploy your Vault in two ways:

Step 4: Do a First Investment

A minimum first investment of 1001 units of your supported asset is required.

  • Why?

    • 1000 units will be permanently locked in the Vault for security.

  • Example: If you are depositing USDC, this equals just 0.0010001 USDC — practically nothing!

This first investment is necessary before you can proceed to the next step: the first rebalance.

Step 5: First Rebalance

After deployment, perform the first rebalance to define allocations across chosen strategies.

You can do the first rebalance using the script vault_usage_example.ts (discussed on next section) or by using the stellar-cli.

First, you need to setup your keys, make sure the rebalancer manager role defined previously is the one you are going to setup. For example, you can set it up using secret key by:

stellar keys add --secret-key rebalancer

then, you will be prompted to write your secret key.

Next, let's make the rebalance using testnet as example. You can do that by:

stellar contract invoke \
  --rpc-url https://soroban-testnet.stellar.org/ \
  --network-passphrase 'Test SDF Network ; September 2015' \
  --id <CONTRACT_ID> \
  --source-account rebalancer \
  -- \
  rebalance \
  --caller <REBALANCER_ADDRESS> \
  --instructions '[{"Invest":["<STRATEGY_ADDRESS>", "<AMOUNT_IN_STROOPS>"]}]'

you can find the strategy addresses on ~/public/<network>.contracts.json.

And that's all!
