Adding Onchain Rails to Existing Products
Wallets and contracts for products people already use — without a rewrite.
The safest way to add blockchain to a live product: keep your database as the source of truth, mirror critical actions onchain behind your own APIs, and roll out chain by chain behind flags.
Start with one touchpoint
Pick the action where verifiability matters most — ownership, payouts, credentials — and leave everything else alone.
Hide the wallet until it helps
Smart accounts and session keys let existing users continue with email while power users bring their own wallets.
