MultiversX Cross-Contract Storage Reads

Note: This skill uses TokenIdentifier (ESDT-only alias). For unified EGLD+ESDT identifiers, use TokenId.

Read another contract's storage mappers directly — zero gas overhead from proxy calls, no async complexity.

What Problem Does This Solve?

When your contract needs to read state from another same-shard contract, you have two options:

1. Proxy call — executes a view on the target, costs execution gas, requires ABI knowledge
2. Direct storage read — reads the raw storage key, costs only a storage read, requires knowing the key name

storage_mapper_from_address gives you option 2.
