Asset registries are structured repositories that store verified data about tokens recognised by a platform or network. Each registry entry holds the contract address, token standard, decimal precision, chain identifier, and symbol associated with a listed token. These fields allow platform logic to query token properties directly from the registry without running live contract calls for every transaction processed across the network. https://crypto.games/ asset registries manage which tokens are eligible for deposits, withdrawals, and contract interactions across each supported network. The registry acts as the authoritative reference for token data, ensuring platform logic applies accurate parameters to every token interaction without relying on unverified external data sources at the point of transaction execution.
What listing processes involve?
- Submission requirements
A token listing submission must include the contract address, verification evidence, and token standard confirmation, with decimal precision data. Submissions missing any required field are returned for completion before the review process begins, ensuring every entry holds a complete data set from the point of initial submission.
- Verification checks
Submitted contract addresses are verified against the token’s deployment record on its native chain. Verification confirms that the contract address matches the deployed token, that the token standard matches the contract implementation, and that decimal precision values align with the contract’s own declared values without discrepancy.
- Approval process
Verified submissions pass through an administrative approval process before the entry is written to the registry. Approval requirements vary by platform, with some applying multi-signature confirmation while others use governance token voting to determine whether a submitted token meets the platform’s listing criteria at the point of review.
- Activation delay
Approved entries enter an activation delay period before becoming available to platform logic. This delay allows platform systems to update token handling configurations before the new listing becomes active, preventing processing errors that arise from platform logic encountering a registry entry before the relevant handling code is deployed.
Cross-network listing management
Tokens listed across multiple networks require separate registry entries for each chain on which they are supported. A token existing natively on one chain with a bridged version on another holds distinct contract addresses on each network, requiring independent verification for each listing entry despite sharing the same symbol field across both entries. Registry deduplication rules prevent the same contract address combined with a chain identifier from appearing more than once within the registry. Duplicate entries produce routing errors where platform logic assigns conflicting token properties to the same address, corrupting balance calculations across affected transactions on the network. Cross-network listing updates must be applied consistently across all relevant registry entries when a token undergoes a contract migration. A partial update that modifies the entry on one network while leaving entries on other networks unchanged produces inconsistent token handling until all entries reflect the current contract data.
Registry maintenance process
Active registry entries are reviewed periodically to confirm that listed tokens continue to meet platform listing criteria. Entries that no longer satisfy the criteria are flagged for deprecation through the same administrative process used for initial approval, ensuring delisting decisions are recorded with the same auditability as listing approvals across the full registry history.
Deprecated entries are marked inactive within the registry rather than deleted, preserving the historical record of the token’s listing period for audit purposes. Platform logic treats inactive entries as unlisted, blocking new transactions involving the deprecated token while retaining entry data for reference during settlement of transactions initiated before deprecation took effect.
Asset registries manage token listings by maintaining accurate, verified, consistently updated entry data across every network a platform supports. Submission requirements, verification checks, cross-network consistency, and deprecation processes collectively determine the reliability of the registry as the authoritative reference for platform token handling.
