YAM is an elastic supply crypto asset, where the supply expands and contracts in response to market conditions with the aim of targeting a 1 USD peg per YAM. One of the interesting differentiators about YAM’s approach is that 10% of each supply expansion (known as a rebase) is used to buy yCRV, a high-yielding basket of USD stablecoins, and is allocated to the Yam treasury which is controlled via community governance. Following a successful audit of the migration contract from Peckshield, Yam Finance is proceeding with the YAMv1 to YAMv2 migration process. The YAMv1 to YAMv2 migration contract was live from 4:20PM UTC, 8/19, and YAMv1 tokenholders were able to migrate for 72 hours, until 4:20PM UTC 8/22. All YAMv1 tokens were eligible for migration, but YAM had to be harvested from staking contracts to migrate. The YAMv2 token is a vanilla ERC-20 token to be used as a placeholder for off-chain voting while YAMv3 is audited.  Currently, there are 3 versions of YAM, this page refers to the YAM v2 d will serve as historical data . The other versions are also available on CryptoCompare at YAM or YAMV1.
