Test the full app and backend user flow on a fork and on Base Sepolia

[ManulParihar]

Summary

Adds a consumer test that runs the whole user flow the way the app and backend would, from signup to an eSIM identifier onchain. The same steps run on a local Base Sepolia fork and on the live network with Pimlico.

Steps covered

Step	Who	What is checked
0	backend	works out the device wallet address at signup
1	app	the passkey resolves to the same address
2	app	deploys the device wallet, gas sponsored
3	backend	registers it with postCreateAccount from its own records
4	app	deployAndBindESIMWallet with no fund access
5	backend	verifies the eSIM wallet belongs to the user (receipt, registry, owner, predicted address)
6	app	buys with buyDataBundleWithTransfer; exact amount moved, no pull access
7	backend	finds the payment by its reference
8	backend	assigns the eSIM identifier, and a second assignment is refused
top-up	app	another purchase on the same wallet
other asset	app	a purchase in a second accepted asset (Circle USDC on live)
external wallet	backend	recordSettledPurchase with ExternalWallet; no tokens move
card	backend	recordSettledPurchase with Fiat and USD; no tokens move
refusals	backend	wrong settlement, reused reference, price over cap, unknown asset

Each step logs its user operation and transaction hashes. On live, the hashes are Basescan links.

Layout

• tests/consumer/flows/userFlow.ts: the steps, written once
• tests/consumer/userFlow.fork.test.ts: fork setup; the backend is a new private key made admin
• tests/consumer/userFlow.live.test.ts: live setup; the real admin key, Pimlico, and 3 confirmations after each write

Running

npm run test:consumer:fork -- --reporter=verbose
npm run test:consumer:live -- --reporter=verbose   # needs .env

A live run spends 2 USDCt and 1 USDC from the admin, plus gas for 5 admin transactions.

Results

• Fork: 14/14
• Live on Base Sepolia: 14/14
• Consumer fork tier: 30/30
