The costs of migrating depends where you migrate from (i.e previous protocol iteration v2.1 or another protocol/AMM). Users with many unique stakes on a single pool will benefit from batch transfers of these positions. Gas costs are dependent on the number of unique pools a user has deposited to. We advise to keep track of ETH's network congestion via gwei.at or Etherscan's for examples. The lower the gwei the lower the migration costs. You can also check our Telegram alert bot to see previous deposits & migrations and compare. To access a rewards program simultaneously, a price estimation for the additional gas will appear.
