Funding · Quadratic matching

Retroactive funding pool

A matching pool that rewards creators many people tip — lots of small supporters beat one big wallet. Matches pay out in a single on-chain sweep.

How it works

For each creator the match is (Σ√cᵢ)² − Σcᵢ — the quadratic top-up over what was actually tipped, scaled to the pool. A creator backed by three $0.01 tips is matched far more than one backed by a single $0.03 tip, even though both raised the same amount. Settlement sweeps every match in one transaction, so sub-cent payouts across a long tail are viable.

Real on-chain USDC — breadth of backers is matched quadratically.
Sybil resistance (honest limits)

Each backer's contribution is weighted: a registered ERC-8004 identity counts full, while fresh, low-history wallets are discounted so a flood of empty sybil wallets can't cheaply inflate the match. This is a heuristic — real sybil resistance needs proof-of-personhood (Passport / BrightID-style), which is on the roadmap. We'd rather ship the honest version than fake the guarantee.
