Pull request overview
This PR adds a new adapter for DeFindex, a vault-based DeFi protocol on Stellar. The adapter uses a fetch-based approach via the DeFindex API to retrieve vault data and calculate total value locked (TVL).
Changes:
- Added DeFindex adapter using the
getConfighelper to fetch vault data from the DeFindex API - Implements TVL calculation by summing all assets managed by DeFindex vaults including idle and invested funds
- Added a dev script for local testing

In `@projects/defindex/index.js`:
- Line 4: Rename the mistyped constant DEFINDEX_VAIULTS_INFO_URL to
DEFINDEX_VAULTS_INFO_URL and update every reference to it (e.g., the use on the
later line referenced in the comment) so the identifier matches the corrected
spelling; ensure the string value remains
`${DEFINDEX_API_BASE_URL}/vault/discover?network=mainnet` and run a quick
grep/IDE refactor to catch all occurrences.
- Around line 6-18: In the tvl function, add defensive checks before iterating
and using properties: ensure res is truthy and res.vaults is an array before
assigning vaults; inside the vault loop verify vault is an object and
vault.totalManagedFunds is an array; inside the fund loop ensure fund is an
object and that fund.asset exists and fund.total_amount is a finite number (or
coercible) before calling api.add; skip entries that fail these checks and
continue processing valid ones to avoid runtime errors from unexpected API
responses.

Summary
/vault/discover) to retrieve vault data and total managed fundsWhy fetch instead of on-chain queries?
DefiLlama's SDK does not have full support for Stellar (no RPC helpers, no contract call abstractions, limited chain tooling). Implementing direct on-chain queries to Stellar/Soroban smart contracts would require significant custom work outside the scope of a standard adapter.
Instead, this adapter fetches TVL data from DeFindex's own API, which already aggregates total managed funds per vault (both idle and invested in strategies).
