Add efixDI adapter (Base + Polygon) with lock-and-mint bridge de-dup

[Ernesto711]

efixDI+ — tokenized Brazilian DI money-market fund

Adds a TVL adapter for efixDI+, a permissionless ERC-20 backed 1:1 by cotas of a BTG Pactual DI money-market fund (Brazilian fixed income tracking the CDI rate, ~15% p.a.), issued under a CVM-registered securitizer (Act 23.635/2025). Website: https://efix.finance

Methodology

• Circulating supply counted across Base (8453) and Polygon (137).
• Bridge de-duplication: the LayerZero V2 OFT bridge is lock-and-mint (Polygon→Base locks efixDI in the OFTAdapter on Polygon and mints the same units on Base). Naively summing both chains would double-count the locked balance, so we subtract the OFTAdapter balance:
  circulating = baseSupply + polygonSupply − OFTAdapterLocked
  (Verified on-chain 2026-07-14: adapter locks 235 efixDI; Base supply is otherwise native treasury issuance.)
• Pricing: efixDI has no public price feed, so circulating supply is valued with the market's own on-chain oracle — NAV(BRL) × Chainlink BRL/USD (the same oracle used by the efixDI/USDC Euler v2 market) — reported via addUSDValue.
• The efixDI Euler market's own vault balances are intentionally not summed — that collateral is already part of circulating supply (avoids double-counting).

Notes

• Tokens are identified by contract address throughout (never by symbol).
• node test.js projects/efixdi/index.js passes cleanly (~$3.05k current TVL).
• Supersedes the approach in Add efixDI+ protocol adapter (Polygon + Base) #18113 by de-duplicating the lock-and-mint bridge instead of summing both chains raw.

Summary by CodeRabbit

• New Features
  • Added DeFiLlama TVL tracking for efixDI+.
  • Reports circulating supply across Base and Polygon with bridge-lock deduplication.
  • Calculates USD value using on-chain NAV and BRL/USD oracle pricing.
  • Includes methodology details explaining supply reconciliation and valuation.

Use the getLogs2 helper (require('./helper/cache/getLogs').getLogs2) instead of api.getLogs(...). Found new usage in this PR:

📝 Walkthrough

Walkthrough

Adds a DeFiLlama TVL adaptor for efixDI+ that aggregates Base and Polygon supply, subtracts Polygon bridge-locked tokens, prices the circulating supply through an on-chain oracle, and exports the standard Base adaptor configuration.

Changes

efixDI+ TVL calculation

Layer / File(s)	Summary
Token and oracle contracts projects/efixdi/index.js	Defines token, bridge adapter, and oracle addresses plus the quote ABI used for NAV-derived USDC pricing.
Supply aggregation and TVL export projects/efixdi/index.js	Fetches Base and Polygon supply, subtracts the Polygon locked balance, converts the oracle quote to USD, records TVL, and exports methodology and the base.tvl entry point.

Estimated code review effort: 3 (Moderate) | ~15 minutes

Rebased onto current main so the diff is a single file (projects/efixdi/index.js). The earlier CI flag about api.getLogs came from stale-base drift in the previous branch state, not from this adapter, which makes no log queries. Local test run: total ~3.06k USD (base 2.60k / polygon 462), with the Polygon side already net of the 235 efixDI locked in the OFTAdapter. Supersedes #18113.

The adapter at projects/efixdi exports TVL:

base                      2.63 k
polygon                   462.00

total                    3.09 k
