Is there a use case for this method at the client? I cannot see it being currently used and the parameter name (index) is a bit confusing.
If there are no plans to use it I'd use remove it until it's needed, but otherwise we can rename index to chainId like in getSlip44ByChainId.

i don't need this method anymore , the one we need is the getSlip44ByChainId, i'll remove it in a separated PR now

There are quite a few entries with repeated symbols in the imported json. This does not look very safe.

i'm actually using this only for non evm ( BTC, SOL, Tron ) , they are unique , for evm the provider https://chainid.network/chains.json is used

so the case of duplicated symbols is handled

Explanation
Current State
The
NetworkEnablementControllertracks which networks are enabled/disabled but lacks information about the native asset identifier for each chain. This information is needed to properly identify native assets across different blockchain networks using a standardized format.Extension UI PR: MetaMask/metamask-extension#39234
Solution
This PR adds a new state property
nativeAssetIdentifiersto theNetworkEnablementControllerthat maps CAIP-2 chain IDs to CAIP-19-like native asset identifiers.For example:
eip155:1→eip155:1/slip44:60(Ethereum uses ETH, SLIP-44 coin type 60)eip155:56→eip155:56/slip44:714(BSC uses BNB, SLIP-44 coin type 714)solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp→solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp/slip44:501Implementation Details
New
Slip44Service: A service that wraps the@metamask/slip44package to look up SLIP-44 coin types by symbol (e.g.,ETH→60,BTC→0).State Updates: The
nativeAssetIdentifiersstate is automatically updated when:NetworkController:networkAdded)NetworkController:networkRemoved)NetworkController:stateChange)Default State: Popular networks are pre-populated with their correct native asset identifiers based on their native currency symbols.
Graceful Handling: If a symbol has no SLIP-44 mapping, the entry is removed from the state rather than storing an invalid identifier.
Dependency Addition
Added
@metamask/slip44package to dynamically look up SLIP-44 coin types instead of hardcoding them, ensuring accuracy and maintainability.References
