Arc Ubi

UBI (ubi.fun) payout estimate for one Arc wallet.

Overview

UBI (ubi.fun) payout estimate for one Arc wallet. Pass ?address=0x.... Our server reads the wallet's UBI balance on Arc just now and prices it against the USDC waiting in ubi.fun's holder payout contract (read every 15 minutes): the estimated share of the next payout, when the next payout list becomes valid and when it was fixed (UBI bought after that counts from the list after it). Pro-rata over all UBI outside the trading pool, the burn address and the ubi.fun hook; ubi.fun computes its list off chain, so it is an estimate, not a promise. A failed read says unknown, never zero. APEX Faucet holds UBI and is not ubi.fun.
