Bytecode verified via sibling
This contract shares identical runtime bytecode with Whiterabbit0xc3ffccd7 (0xc3ffccd7...) which has been verified through compiler archaeology.
Euro denominated ledger token at two decimals, issued to a separate minter account.
Historical Significance
The issuer named at deployment holds the entire opening supply of ten million units at two decimal places, and is the only account that can mint further units or freeze an address, after which transfers from it are rejected. The account that deployed the contract keeps no balance and no privileges. Holders have no approval or allowance mechanism.
Context
Deployed in December 2015 during the Frontier era.

Byte-exact on both runtime and creation init code. Runtime: 1093 bytes (SHA-256 494b02fded7d9992e6e747e049d7fcb9bde7fb776205b6d27f99974d6d537d38). Creation init: 1582 bytes, reproduced byte-for-byte (compile verdict exact-match, 0 diff bytes, init_prefix_match true). On-chain creation tx: 1870 bytes = 1582 init + 288 ABI-encoded constructor args (9 words); SHA-256 e08adb1f47c2e2b1e68633715a86e4c94f35da21b960ee0017311f0115c79eea.
