DropRank

Scan your wallet. Know your airdrop odds. Mint the proof.

DropRank is a Base mini-app that scores any wallet's airdrop readiness, shows exactly what to improve, and lets you mint your score as a soulbound badge — fully on-chain, non-transferable, refreshable.

Live: droprank.xyz

What it does

  • WALLET — Score v2. 10 criteria sourced from real airdrop snapshots (ARB, OP, ZK, LayerZero): activity spread, protocol diversity, bridging, grouped identity, dust-excluded volume, bounded sybil malus. Percentile ranked against every scanned wallet.
  • RADAR. 12 actionable quests mapped to the score categories, with a diversity tracker and direct links to Base reward programs.
  • NEWS. Base ecosystem feed — direct publisher RSS, og:image thumbnails, weekly/monthly separators, EN/FR.
  • DISCOVER. Curated Base protocols to explore.
  • YIELD. Risk-adjusted Yield Score across Base, Ethereum, Optimism and Arbitrum — three profiles (STABLE / MAJORS / DEGEN), official-site links only, two-level disclaimer.

On-chain badge

Soulbound ERC-721 on Base mainnet — 0x5d3febf136e461be015713e2947bbd0940c8e92b. Score attested off-chain via EIP-712 and rendered as a fully on-chain SVG. See contracts/.
