Homestead Era

Historical Significance

This GLYCOIN deployment is the earliest identified member of a cluster of named GLY token contracts from one deployer in June 2016. The series records repeated token experimentation during Ethereum’s first year.

Context

Ethereum had entered Homestead in March 2016. Token interfaces were still evolving, and independent developers could deploy multiple live contracts under related names.

Description

GLYCOIN (GLY) was deployed at block 1,651,137 on 6 June 2016 by 0x3926a029c7251012dc7382d98650bd9c95cc21ce. The same address deployed a sequence of GLYCOIN and GLYCASH contracts over the following week. Each deployment has its own contract address and token balances.

The on-chain record establishes the deployment and token identity. A contemporary project statement explaining why the creator made several deployments has not been identified, so they should not be treated as interchangeable versions of a documented product.
