A commitment path beside the AMM.

Flow Buy does not replace normal swapping. It adds a stricter optional route whose principal, escrow, daily round, and beneficiary must be proven atomically.

01

Buy through Flow

The payer signs a bounded intent. Flow Buy settles the exact ETH principal and binds it to that authorization.

02

Share the daily round

Purchased HETH enters a seven-day hard lock. Your reward is projected from the day’s total ETH flow and becomes final when that round closes.

03

Settle at maturity

After seven days, anyone can settle the receipt. Purchased HETH and the finalized reward go only to its fixed beneficiary.

What must remain true

Design contract
01

Opt-in only

Ordinary swaps remain liquid and earn no Flow mining reward.

02

Actual principal

Reward weight uses canonical ETH settled in the same call—not a user-supplied number.

03

Daily ceiling

Demand can change the same-day rate, but cannot pull emission forward from a later day.

04

Exact escrow

The entire purchased HETH output is locked for exactly seven days with no early exit.

05

Authenticated round

The payer authorizes the beneficiary, expected round, boundaries, nonce, deadline, chain, and adapter.

06

No privileged path

No owner, admin, founder allocation, rescue, arbitrary mint, or POL extraction path.
