Claim your onchain airdrop
Prove an active Coinbase One membership with Base Verify, then claim once per identity on Base Sepolia. Deduplication is enforced onchain — the same person can't claim twice, even from a different wallet.
Step 1 — Get your verification
Sign a message so the backend can issue an EIP-712 verification bound to your wallet.
Connect your wallet to start.
