  • Total $4 million USD (100 million tokens) reserved for accredited individuals and institutions
  • There is an individual cap limit until block number 4,431,102 (~5:00 PM PDT (UTC -7)). More details in the next section below.
  • The token sale ends once either the hard cap of $20 million or block number 4,617,363 (~ 30 days) is reached
  • Minimum cap of 100 million tokens (10%, ~$4 million USD) must be sold to be considered a successful sale. If we don’t reach the minimum cap after ~30 days, all ETH will be returned to registered participants holding a GMT balance.
  • If we reach the 100 million token min cap but do not reach the full 500 million token ($20 million) hard cap, any unsold tokens will be sent to the GMT fund.
  • Only approved registrants will be able to participate in the token sale. You can register on our website: https://www.mercuryprotocol.com. If you registered and received an email about registration from us, you’re good to go.

Individual cap details

Block 4,427,945 to 4,430,049 (~ 9am PDT — 5pm PDT):
  • 7 ETH cap
  • Gas price is limited to 50 Gwei
Block 4,430,050 to 4,431,101 (~ 5pm PDT — 9pm PDT)
  • 28 ETH cap
  • Gas price is limited to 50 Gwei
After block 4,431,101 (~9pm PDT)
  • No cap
  • No gas price limit

After block number 4,431,101, individual cap and gas price limit will be removed. Your transaction will NOT go through if the gas price is set for more than 50 GWei during these first ~12 hours.

Note that the 28 ETH cap in the second cap period is INCLUSIVE of any ETH you send during the first cap period. Therefore, if you send 7 ETH in the first cap period, you can send an additional 21 ETH during the second period, for a total of 28 ETH.
