Prop 55: Contract Update: Event Transparency for Fungible Assets and NFTs

1. TL;DR

This proposal aims to update Initia’s core modules to improve event transparency for fungible and non-fungible tokens. The updates will:

  • Add sender/receiver addresses to fungible asset events
  • Include NFT metadata in mint events
  • Emit object deletion events with owner information
  • Support NFT transfers via collection address and token ID

These changes span multiple modules and are implemented across three linked PRs.

2. Background

Currently, when a fungible asset is moved from one account to another, the transaction event logs do not include the sender and receiver addresses—only the store addresses are available. As a result, an additional API query is needed to determine those addresses, which is inefficient.

Similarly, for NFTs, the metadata of a minted NFT is not available in the transaction event logs.

3. Proposal Details

The following changes are proposed to improve the current spec, which is detailed in “backgrounds”
