Stellar (XLM) has announced the introduction of CAP-67, a structured event stream designed to enhance the transparency and traceability of token-value movements on its blockchain. This initiative aims to provide detailed insights into transactions, whether they involve classic operations or smart contracts, according to Stellar.
CAP-67 offers a single, structured event stream that captures every movement of value on the Stellar network. This development is significant for developers and users who seek to understand the intricacies of transactions and smart contracts. The structured event format is expected to streamline the process of tracking and auditing transactions.
The new system provides clear examples of events, detailing the order of addresses involved in a transaction. The first address in the topic represents the sender, while the second address denotes the receiver. Additional details, such as asset information, are included in an optional fourth topic.
Stellar’s CAP-67 outlines specific cases, including transfers utilizing the Stellar Asset Contract (SAC) and operations involving liquidity pools. The structured event data model includes key transaction details such as contract IDs, data types, and transfer amounts, ensuring comprehensive coverage of all transaction types.
One notable feature is the introduction of a new SCAddressType for liquidity pools and claimable balances. This allows for more precise tracking of these specific transaction types, with liquidity pool addresses beginning with an “L” and claimable balances starting with a “B”.
The implementation of CAP-67 is poised to enhance the Stellar network’s utility by providing a clearer picture of token movements. This can be particularly beneficial for developers creating decentralized applications (dApps) and for users who require detailed transaction histories for compliance and auditing purposes.
By unifying the format for all token movements, including simple transfers, smart contract events, and liquidity pool operations, Stellar aims to ensure that no detail is overlooked in a token’s lifecycle. This move is expected to bolster confidence in the network’s transparency and operational integrity.
