Sprouts

Every swap rounds up. The change buys SKR and stakes it, into a garden only your phone's Seed Vault can open.

An Android app for the Solana Seeker, built for the CLOCK IN hackathon. You approve once per trading wallet; after that a daily job pulls at most your daily limit in USDC, swaps it to SKR through Jupiter and stakes it to your Seed Vault key, in one transaction. Only your Seed Vault key can unstake. Nothing here holds user funds.

What the approval does

It uses the Solana Foundation's Subscriptions program (audited by Cantina). The program becomes the delegate on your USDC account; each pull must also fit a recurring delegation capped at your daily limit, $5 by default, which the program enforces on chain. Revoke it at any time from the app or from this site with the wallet that approved.
