// Reward a purchase. No wallet, no keys, no gas.
await stellarback.reward({
  user: "usr_71bQ",
  amount: 1.25,           // 2% of a $62.50 order
  asset: "USDC",           // or your branded reward asset
  memo: "order_88213"
});

// Later — the user takes true ownership.
await stellarback.withdraw({
  user: "usr_71bQ",
  to: externalWallet     // custodial → self-custody
});

Why StellarBack

Loyalty that isn't trapped.

Points expire and stay locked to one brand. StellarBack rewards are real, portable value — owned by the customer, interoperable across your network, and cheap enough to issue on every sale.

🪙

Rewards they own

Issue value the customer holds — transferable, redeemable, and withdrawable to their own wallet. Not points on your ledger.

🫥

Crypto-invisible UX

Custodial accounts mean no seed phrases, no gas, no wallet setup. It feels like a normal points balance — until they choose to self-custody.

📉

Micro-rewards that pencil out

Pooled + muxed accounts remove per-user reserve costs. Sub-cent settlement makes rewarding every transaction economical.

🔁

Portable & interoperable

Account-to-account transfers make rewards giftable and spendable across every merchant in your network.

🎛️

Programmable controls

Issuance caps, expiry, authorization, and clawback give you real governance — the controls a closed points ledger can't match.

🧩

Embeddable anywhere

A clean API behind any app, checkout, or PSP — pairs natively with Paydapter, works standalone with everyone else.

🤖

A loyalty provider for agents

Behind an AI shopping agent's pluggable wallet interface (like Paygent's), StellarBack can be the rewards program it applies — points that are actually owned, not just tracked.

How it works

From purchase to portable value.

STEP 1

Connect

Reward

STEP 3

Spend or send

Users redeem across your network or gift to friends — account to account, near-instantly.

STEP 4

Own

Anytime, a user can graduate to self-custody and withdraw to their own wallet.
