Address Format

The address format used in Substrate-based chains like Astar is ss58. Ss58 is a modification of Base-58-check from Bitcoin, with some minor modifications. Notably, the format contains an address type prefix that identifies an address as belonging to a specific network. Astar Network uses two kinds of addresses:

  1. An Astar Native address or ss58 address, which uses 256 bits.
  2. An Astar EVM or H160 address, which starts with 0x, and uses 160 bits.
