Hello @xingtianchunyan @zz_tovarishch @Hanssen .

Dular completion report

What was delivered

Milestone 1: Phone identity + M-Pesa deposit ramp: OTP verification via Africa’s Talking, database-backed phone → Fiber pubkey registry with public lookup, production Daraja STK Push deposits settling through Fiber, RUSD credited after settlement.

Milestone 2: USSD interface (simulator-tested): full menu (balance, send, receive, deposit, PIN), 20 Africa’s Talking simulator sessions committed under verification/milestone-2/. No production dial code, a dedicated code was required for crypto services and is out of budget, so this stays simulator-only.

Milestone 3 + approved pivot: self-custody web wallet: per committee feedback the app moved from operator-ledger to Fiber-native. Browser runs the Fiber wallet (keys generated and PIN-encrypted on-device), phone numbers map to user-owned Fiber identities, phone-number sends and standard Fiber invoice send/receive (including external Fiber wallets) settle over Fiber, not an internal ledger. 53 automated tests pass, lint and build clean.

Live counts at reporting time: 30 users, 31 channels, 57 successful Fiber payments, 32 completed ramp orders. Each channel entry carries its funding tx hash + explorer URL; each ramp order links its redacted verification record.

Reminder: Fiber payment hashes are off-chain identifiers, verify via Fiber RPC get_payment/list_payments. CKB Explorer verifies the channel funding cells (FundingLock 0x6c67887fe201ee0c7853f1682c0b77c0e6214044c156c7558269390a8afa6d7c, RUSD 0x1142755a044bf2ee358cba9f2da187ce928c91cd4dc8692ded0337efa677d21a).

Pilot results (n=23)

  • Avg ratings (/5): onboarding 3.96, deposit 3.70, send 3.96, reliability 3.39
  • Would use again: 19/23.
  • 7 reported no issues. Remaining feedback clusters: STK/liquidity messaging, invoice expiry and QR edge cases, Swahili coverage, recovery-phrase backup, PIN naming. Full responses: verification/milestone-3/pilot_feedback.csv

Stated limits

  • Feedback coverage 23/30 (onboarding hit 30).
  • RUSD is a capped testnet pilot asset, not production money.
  • USSD is simulator-only.

Requesting committee review and close-out on the above evidence. Thank you for the support and the architecture guidance that made the Fiber-native pivot happen.
