# TODO List - DeFi Oracle Meta Mainnet (ChainID 138)

## Overview

This file preserves a consolidated historical backlog snapshot from an earlier planning phase. It is still useful for context, but it is no longer the primary current tracker.

**Last Reviewed**: 2026-04-13
**Status**: Historical consolidated backlog snapshot
**Use Instead for Current Work**:
- `docs/operations/tasks/NEXT_STEPS_LIST.md`
- `docs/operations/tasks/ACTION_ITEMS.md`
- `docs/PROJECT_OPTIMIZATION_STATUS.md`

**Historical Totals at Time of Snapshot**:
- Total tasks: 142 (87 development + 5 pre-production + 25 MetaMask integration + 15 deployment + 10 integration)
- Completed: 112 (code tasks)
- Remaining: 30 (15 deployment + 10 integration + 5 pre-production operational tasks)

**Historical Milestone Note**: Core implementation was marked complete when this roll-up was written, but deployment, integration, archival cleanup, and operator hardening continued afterwards.
