## Issue being fixed or feature implemented
Platform in the scope of credit withdrawals, need a way to get the
status of an Asset Unlock by index.
## What was done?
A new RPC was created `getassetunlockchainlocks` that accepts Asset
Unlock indexes array as parameter and return corresponding status for
each index.
The possible outcomes per each index are:
- `chainlocked`: If the Asset Unlock index is mined on a Chainlocked
block.
- `mined`: If no Chainlock information is available, and the Asset
Unlock index is mined.
- `mempooled`: If the Asset Unlock index is in the mempool.
- `unknown`: If none of the above are valid.
Note: This RPC is whitelisted for the Platform RPC user.
## How Has This Been Tested?
Inserted on `feature_asset_locks.py` covering cases where Asset Unlock
txs are in mempool, mined and not present.
## Breaking Changes
no
