Users can test Index Vaults by creating their own demo vault on Optimism Sepolia using this link.
Before beginning, you will need to switch to the Optimism Sepolia test network and ensure your wallet is funded with test ETH and test USDC assets.
To complete these steps, follow this step-by-step guide.
Follow the guide below to get started:
Index Vault behavior is very similar to Credit Vaults, with exceptions in the following areas:
Instead of loans, IVs utilize an instrument called Investment to deploy funds.
Investments are LP positions at non-IV vaults on TrueFi.
Because TrueFi vaults implement the ERC-4626 interface, interactions with all types of TrueFi vaults work the same way.
Instead of an array of loans, IVs hold an array of investments.
When calculating IV valuations, the IV iterates through that array and calls ERC-4626 totalAssets() on each of the underlying vaults to fetch the value of each investment.
Capital allocation happens through proxying one of the following methods:
deposit(assets, receiver)
mint(shares, receiver)
Allocation is only possible if the target vault’s token is already registered on the vaultsRegistry.
Adding a token as a potential investment adds the token to the list of tracked asset balances and values.
In order to register a token, the token must:
Be one of the allowlisted types of TrueFi products (i.e. Lines of Credit, Credit Vaults, or Flexible Portfolios)
Not be registered already
unregister removes a token from the tracked assets list.
Redeeming and withdrawing happens through proxying one of the following methods:
withdraw(assets, receiver, owner)
redeem(shares, receiver, owner)
Index Vaults cannot be closed while holding any active investment. Similar to how vaults cannot close before maturity unless all underlying loans are inactive, IVs cannot close unless all investments have closed first.
TrueFi's "Fund of Funds"
Index Vaults are currently in TrueFi Labs beta.
Smart contracts are available for builders to use and experiment with. If you would like to learn more, send a message here.
Index Vaults enable "fund of funds" activity on TrueFi, by allocating capital across multiple underlying TrueFi products (such as Asset Vaults, Credit Vaults, or Lines of Credit).
Index Vaults do not allow managers to disburse funds to themselves, or to make loans directly to borrowers from Index Vault funds.
