On-chain document/agreement holder (Homestead, Mar 2016): stores owner + a constructor-set string, returnContract() returns the text, kill() lets the owner self

Frontier EraVerified Source

Historical Significance

One of 115 byte-identical-runtime deployments of a minimal contract used to persist a text document or agreement on-chain in early 2016.

Context

Compiled with soljson-v0.1.3 (optimizer OFF); exact match of the 476-byte runtime. The early PUSH29/DIV selector-dispatch idiom is characteristic of the v0.1.x series.

SolidityExact bytecode match(980 bytes)
Compiler: soljson

Exact runtime bytecode match. Runtime: 476 bytes (byte-for-byte), compiled with soljson-v0.1.3+commit.028f561d, optimizer OFF. Reconstructed from disassembly (no published source). Creation varies per deployment because the constructor takes the document string as an argument; the 476-byte runtime is the shared cluster invariant (the string is storage, off-bytecode).
