Exchanging stamps and rewards for TEDS

There are two ways to turn loyalty into TEDS, both available from a campaign’s detail page in the app:

1. Exchange a single stamp for TEDS — sell stamps individually as you collect them.
2. Exchange a completed reward for TEDS — once a stamp card is full, swap the reward itself for TEDS instead of redeeming it in-shop.

The campaign also lets you buy stamps using TEDS (the reverse direction) — see Spending TEDS on other partners.

How a reward’s TEDS value is calculated

From the code: rewardValue = tedsPerStamp × goal.

So a campaign with a goal of 10 stamps and 100 TEDS per stamp gives a reward worth 1,000 TEDS (£10) when exchanged.

When the partner’s wallet is insufficient

If your exchange happens at a moment when the partner’s TEDS wallet is too low to fully fund it, the transaction is recorded as stamp-exchange-pending or reward-exchange-pending in your transaction history. The TEDS still credit to your balance (your headline number includes pending TEDS); the partner-side settlement is what’s outstanding.

The visible UI doesn’t show a specific deadline for pending exchanges to clear — see Understanding pending vs available TEDS.

What we don’t document precisely at v1

• Exact button labels and confirmation copy in the campaign detail page — varies by state and wasn’t fully audited here.
• The 90% / 10% split I previously described — the underlying TEDS value calc is tedsPerStamp × goal from Campaign.jsx, but the network-fee split isn’t exposed in the visible member UI we audited. Don’t take that 90/10 figure as gospel; we’ll re-document once we’ve confirmed the exact split from backend.

In one sentence

Per-campaign actions: exchange a stamp → TEDS, exchange a completed reward → TEDS, or buy stamps using TEDS. Pending state if partner’s wallet is short.
