DAO-era ERC-20-shaped token, May 2016. Symbol is the Greek capital letter Xi. Fixed cap 15,000; 1 token per 0.001 ETH via buy().
Historical Significance
Xi is among the earliest token deployments where the symbol field carries an actual non-ASCII Unicode character (the Greek capital letter Ξ, U+039E). Pre-byzantium contracts almost universally used 3 to 5 ASCII letters for symbols; Xi's use of Ξ requires UTF-8-aware token explorers, which most 2016 wallets could not render. The fixed-price 0.001 ETH per Ξ launch math sets the deployer's implied target raise at 15 ETH at 100% sellout, modest even by mid-2016 standards.
Context
Pre-0.4.7 solc, late homestead / early DAO era (around May 2016). Deployed by 0xee06f74a7f9d8d2b35d63a3ef27bf48eb12c47cf. ETH price at deployment was approximately $10. The contract is one of 27 token deployments in a 5-day burst by the same author.

Key Facts
Description
Xi (symbol: Greek capital Ξ) is a May 2016 ERC-20 token with totalSupply=15,000, decimals=0, and a fixed buy price of 1 Ξ per 0.001 ETH executed via the buy() function (selector a6f2ae3a). The contract is built on the ConsenSys HumanStandardToken template with extensions: MintableToken, Ownable, killable.
Dispatcher selectors (14 total): name 06fdde03, mintToken 1003e2d2, totalSupply 18160ddd, kill 1c02708d, transferFrom 23b872dd, decimals 313ce567, standard 5a3b7e42, balanceOf 70a08231, owner 8da5cb5b, symbol 95d89b41, buy a6f2ae3a, transfer a9059cbb, approveAndCall cae9ca51, allowance dd62ed3e, transferOwnership f2fde38b. The pre-0.4.7 dispatcher shape (PUSH4 + EQ + JUMPI without DUP2) confirms the contract was compiled with solc 0.3.x or very early 0.4.x.
Deployed in the DAO era, six to eight weeks before TheDAO hard fork. The Greek capital Xi symbol Ξ is the same letter Vitalik adopted for Ethereum's branding (the cursive 'Ξ' or ether-sign), suggesting Xi was an early branding-overlap meme token.
Source Verified
Template identification only, not a byte-for-byte source-code crack. The 14 dispatcher selectors and pre-0.4.7 PUSH4-EQ-JUMPI pattern match the ConsenSys HumanStandardToken plus Mintable, Ownable, and killable extensions, but I have not produced an exact compiled match. Acquirable for 0.001 ETH per token.
