Readonly API Service

BVM will provide a JSON RPC service, which will fully comply with the eth_call method standard, allowing developers and users to query the contract's internal state and simulate transactions through this interface.

Address Type Conversion During Query

When the BVM stores data of the address type, it only stores 20-byte long hex addresses, and the BVM does not handle any form of BTC address conversion. Therefore, when querying, developers need to pre-convert the BTC address to a 20-byte long hex address before performing the query. This also applies to the query of contract addresses. The Veda-SDK will provide utility functions to assist developers in address conversion.
