Hi, I’d like to take on this issue.

I have experience working with Stellar/Soroban and frontend transaction flows. I’ll implement a contribute action that builds the transaction with proper token approval, integrates Freighter for signing, and handles submission with clear success/failure responses.

I’ll ensure clean handling of inputs (from, amount), return ledger confirmation details, and add an integration test against the Stellar testnet.

Estimated completion: a few hours.
