Fees & fine print
What does it cost?
1% fee · 50% of it buys back BOOST. The 1% goes to the BoostBuyback contract: 50% of it is swapped for BOOST through the canonical pool and sent to the Boost treasury (the owner can switch that to a burn), the rest pays for running Boost. Fee is hard-capped at 5% on-chain. Robinhood Chain gas is ~$0.001. If the recipient uses the gasless claim, our relayer pays gas and keeps ≤1% of that claim (contract cap 3%).
What if they never claim?
You can refund your own gift after 180 days from the contract (refund(giftId)). After 365 days without any activity the Boost owner may sweep the balance to treasury.
How do they prove it's them?
They put a one-time code in their bio and we check the public profile; X login is coming. The attester then signs an EIP-712 claim bound to their wallet — funds can only go where they choose.
Is it audited?
HandleVault is small (≈250 lines), built on OpenZeppelin 5, and covered by 18 Foundry tests including fuzzing and re-entrancy; BoostBuyback by 13 unit + 3 mainnet-fork tests. Verified source: 0x22B60e52…. Not affiliated with X, Instagram, TikTok or Robinhood.
