Impact

The Instawards work moved Sozu from concept to infrastructure.

For NGOs, like https://www.mujeres2000.org.ar/ the impact is operational: they get a simpler way to distribute aid, microcredit or subsidies without spreadsheets, manual reconciliation or cash-heavy logistics.

For beneficiaries, the impact is access: they receive a wallet that can hold USDC, work from a phone, use passkeys instead of seed phrases and become part of a broader programmable financial network.

For the Stellar ecosystem, the impact is distribution: Sozu becomes a user-facing layer that can bring real beneficiaries into Stellar through the existing SDP rails.

This is the key outcome: Sozu does not only demonstrate a wallet.

→ It demonstrates a distribution loop.

Challenges

The hardest part of the process was not one isolated feature. It was alignment.

The project required to align passkey authentication with Stellar account models, align SEP-10 with SEP-24, align C smart accounts with G signers, align beneficiary identity checks with CSV data, align SDP tenant headers with production requests, and align the user experience with a protocol flow that was never designed to feel consumer-simple.

Several implementation challenges appeared during Week 4:

SDP sessions had to reset correctly when users switched Sozu accounts.
SEP-10 needed to use the passkey-derived G signer.
