The problem Bank of Celo solves

Bank of Celo makes DeFi more fun and community-driven by letting users claim daily rewards in CELO or DEGEN.
It allows the community to donate and fund vaults, making tokens accessible to newcomers.
Users can join jackpots and leaderboards for gamified engagement.
Upcoming savings vaults let people earn yield from stable tokens like cEUR or USDC.

Challenges I ran into

Donations firing success too early. You were showing a “success” toast before the tx actually confirmed.
Fix: Wait for on-chain confirmations before triggering success UI.

Jackpot flow error. A bug in the jackpot path.
Fix: Patch applied via a dedicated PR to stabilize the jackpot round/claim path.

ERC-20 approval flow glitches. Users hit issues around “Approve → Donate” sequencing.
Fix: A PR specifically addressed transaction approvals, likely splitting/guarding approve vs. donate states to prevent double submits.

UI/UX polish & state handling.

Header button bugs → fixed in a focused PR.

Scroll behavior issues → separate PR from a contributor refined scrolling.

Donation UX → added loader/disabled state during pending approval/
