Bootstrap Address Module

[lowhung]

Context

The Address State module tracks per-address UTXOs, transactions, and totals (sent/received amounts). It currently processes address deltas block-by-block starting from genesis or via the Mithril snapshot fetcher flow.

Problem

When bootstrapping from a snapshot (e.g., epoch 500), the address state module needs to initialize from UTXO data in the snapshot rather than replaying all blocks from genesis.

Acceptance Criteria

• Address state initializes from snapshot UTXO data during bootstrap
• Address indexes built correctly from snapshot
• Normal address delta processing works after bootstrap

Testing Requirements

• Bootstrap from fixture snapshot initializes address state correctly
• Address Blockfrost queries return correct data after bootstrap

Definition of Done

• Address state initializes from snapshot without block replay
• Address queries work correctly after bootstrap
