Understanding UOMI Addresses

UOMI, being built on Substrate and supporting dual Virtual Machine environments, utilizes a unique address system. The blockchain implements the SS58 address format, which is derived from Bitcoin's Base-58-check encoding with specific modifications to support network-specific addressing.

A key feature of the SS58 format is its network identifier prefix, which ensures addresses are uniquely associated with the UOMI network.

Two Address Types

Due to UOMI's support for both EVM and Wasm smart contracts, the network operates with two distinct types of addresses:

1. Native Address (SS58)

• Uses 256 bits

• Based on Substrate's SS58 encoding

• Used for native blockchain operations and Wasm contracts

2. EVM Address (H160)

• Uses 160 bits

• Begins with "0x" prefix

• Compatible with Ethereum-style operations

• Used for EVM contract interactions

This dual-address system allows UOMI to maintain compatibility with both ecosystems while preserving each environment's unique features and capabilities.
