Key Facts
Description
GTT (GTT) is an ERC-20 style token contract deployed at block 2,587,863. Its runtime and creation bytecode both match the ethereum.org token tutorial compiled with solc v0.4.0+commit.acd334c9 (optimizer on), byte for byte. 3 contracts on mainnet share this exact runtime bytecode, so one source verifies all of them. Total supply at deployment was 150,000,000,000,000,000 base units with 8 decimals.
