**Overview** The Internet Computer (ICP) ecosystem is evolving, and as part of ongoing improvements to the ledger standards, new block types will be introduced that ledgers on the ICP will support. This work is part of ongoing efforts to develop Real-World Asset (RWA) ledgers, ensuring they support essential features for tokenized asset management. It is crucial for developers working on wallets, dashboards, token trackers, and indexers to be aware of these changes to ensure continued compatibility.

**Why This Matters** If your system parses ledger blocks for transaction history, analytics, or indexing, these new block types might affect your implementation. Ignoring them could result in broken parsing logic, missing transactions, or incomplete data representation.

**What’s Changing?** New block types will be introduced to capture specific ledger events beyond standard transactions. These may include:

- **Fee Collector** – Records fee collector changes
- **Authorized Mint and Burn Blocks** – Recording explicit minting and burning of tokens, making these operations visible at the block level.
- **Governance or Compliance-Related Blocks** – Potentially capturing administrative actions that affect ledger state.
- **Other Future Extensions** – Additional block types may be considered to support broader asset management use cases.

**Who Needs to Take Action?** Developers and maintainers of:

- Wallets that parse transaction history
- Custody providers that monitor transactions to addresses in custody
- Token dashboards displaying ledger events
- Indexers that track ledger activity
- Analytics tools relying on ledger data

**Next Steps**

- Ensure you **have monitoring** in place to detect if and when new block types appear in the chain.
- **Register your interest** in this thread if you are impacted or want to stay informed.
- Consider **participating** in the Tokens Working Group to help shape these developments and provide feedback.

**Get Involved** Discussions on these updates are ongoing. If you have feedback or need clarifications, feel free to engage in the community conversations.

We encourage all developers working with ledger data to stay informed and proactively update their systems to accommodate these change
