Rainbow completely centralized this airdrop. To stop phishing scams, they made the deliberate decision to hide every user's "Merkle Proof" (the secret cryptographic code needed to execute the claim on the blockchain) on their own private servers. The only piece of software authorized to fetch that code is the official Rainbow mobile app.
Because they hid that data, Rabby can't help you. Zapper can't help you. And the Basescan link is a dead end because we physically cannot extract your specific code from Rainbow's servers to plug into it.
Furthermore, because the Rainbow browser extension is currently hard-coded to redirect to the mobile app for claims, you are mathematically soft-locked out of using your Mac.
It's a three-way failure: Rainbow built a walled garden, they forced you to use mobile, and iOS 26's Bluetooth stack is currently breaking the high-security signing handshake with the Ledger Stax.
