Brisk — Tap or scan to pay in stablecoins. No seed phrase. No gas.

The problem

Paying should be the easy part.

It isn’t. Both halves of the checkout are broken — just in opposite ways.

01

Card networks take 2–3% — and settle in days

Every sale loses a cut to the network before the money even moves. The business waits days for funds it has already earned, while customers pay for the privilege in higher prices.

02

“Pay with crypto” fixed the fee and broke the experience

Gas fees, seed phrases, wallet pop-ups, addresses to paste and verify. The economics got better and the product got worse — nobody taps a hardware wallet to buy a coffee.

Shoppers want tap-and-go. Businesses want the money now, without a 3% haircut. Brisk gives both sides exactly that — today, not in some whitepaper future.

What Brisk is

One app, two sides, one Google sign-in.

A tap-to-pay wallet for shoppers and a point-of-sale for businesses — the same account, switched in a tap.

Self-custodial

Your money is yours. Accounts are created from a normal Google sign-in and every payment is confirmed with Face ID or fingerprint — no seed phrase to lose.

Feeless

The payer is charged the exact amount and pays $0 in gas. A shopper never needs to hold any token other than the dollars they’re spending.

Sub-second settlement

Payments settle on-chain in under a second. Businesses have the funds the moment a customer pays — not in two business days.

For shoppers

Feel like Apple Pay. Run on open money.

Everything you actually do at a counter — and a few things cards can’t do.

Tap or scan to pay. Hold your phone to a Brisk terminal, or scan the merchant’s QR. Pay the exact amount on iPhone and Android.
No app? Pay in the browser. Scan a Brisk QR or open a payment link and complete it on a web page with a Google sign-in.
Truly feeless. Whatever the total, you pay $0 in fees — no gas, no card fees, no second token to hold.
Add money by card, cash out to your bank. Top up with a card, Apple Pay or a bank transfer, and cash out to your bank account, through Coinbase, right inside Brisk. No exchange account juggling, no gas.
Your money earns while it waits. Move idle balance into Save with one tap; it earns yield in the background and stays instantly spendable.
Your @brisk username & photo. Pick a handle once, then friends send you money by name — never a 0x… address.

Brisk tap-to-pay screen: hold your phone near the terminal or scan a QR code to pay in USDC

Send to anyone, any way. A @brisk username, a raw address, or a SuiNS .sui name — Brisk resolves and verifies it before you confirm.
Tap phone-to-phone. Two friends can pay each other on the spot: one enters the amount, the other taps. No addresses, no setup, feeless.
Gift cards. Browse businesses, buy a gift card, share it by link. Recipients claim it, redeem it at checkout, or re-gift it.
A clean history. Businesses by real name and logo, friends by username and photo, with an on-chain receipt for every purchase.

For business

Your money now. A flat 0.8%.

In-store, online and in your ERP — one account, paid the moment a customer pays.

Go Pro in seconds

Flip to business mode from the same account. Setup is one-time and smart — come back on a new phone and Brisk recognizes your business instead of asking again.

A proper business profile

Name, VAT / Tax ID, address, contact details, category and logo — shown consistently everywhere customers see you: checkout, gift cards, activity.

Charge by tap or QR

Enter an amount, then have the customer tap to pay or show a QR they scan. The QR opens the app — or lets them pay in the browser with no app at all.

Online store? Plug and play.

On WooCommerce, install the Brisk Pay plugin, paste your API key and save — USDC checkout is live, priced in your store’s currency, with orders confirmed automatically. On any other stack it’s one API call: create a session, send the customer to the hosted pay page, get a signed webhook. AI-agent payments work out of the box. Read the quickstart →

POS / ERP terminal integration

Pair Brisk with the point-of-sale or ERP you already run using a short terminal code. Your system starts a sale, it’s pushed to the phone in real time with a buzz, the terminal charges automatically over tap or QR, and the on-chain transaction reference is reported straight back to your ERP — ready for tax reporting. Cancel any time; every sale reconciles.

Receiving accounts

Collect into named accounts that keep your private treasury hidden from customers, and sweep funds to your treasury whenever you like.

Payment links & QR

Create a shareable link, rendered as a QR — single-use or reusable, with an expiry, one-tap cancel and status tracking. The payer needs no app.

A free gift-card program

Any business can sell gift cards, and you’re paid upfront at purchase. Customers buy, share and redeem them — no third-party platform taking a cut.

Instant settlement, a real dashboard, cash-out to your bank

Funds are yours the moment a customer pays — not in two business days, and for 0.8% instead of a 1.5–3% card fee. The merchant dashboard shows balances, every payment with its on-chain receipt, CSV export for your accountant, payouts, API keys and webhooks. When you want euros or dollars, cash out to your bank from the app or the dashboard through Coinbase: confirm the payout, send with one tap, done.

How it works

The primitives, plainly.

Four building blocks from Sui and Brisk’s Move modules make “tap, pay, done” real.

01

Protocol-level gasless transfers

Supported stablecoins move peer-to-peer for $0.00 via Sui’s native gasless balance transfers. The sender needs no SUI for gas — it’s built into the protocol, not a relayer trick.

02

zkLogin + Passkey + Enoki

Self-custodial accounts from a Google sign-in, biometric signing, and Enoki gas sponsorship — so a wallet feels like a normal app, with no seed phrase and no pop-ups.

03

Two-leg payments

Leg one settles the money via native gasless send_funds — the source of truth. Leg two best-effort sponsors record_payment, minting an on-chain receipt. If leg two is skipped, the money has already moved.

04

Move modules on Sui

A small, composable set of on-chain modules: spending_vault (Save), merchant_registry (identity and tills), and payment_receipt (receipts and records) — auditable and open.

Agentic finance on Sui

Give an agent a wallet. Give it a spending limit you can see.

Brisk pairs an AI agent to a capped on-chain wallet over MCP. The agent can pay for things — within limits enforced by the chain, not just the app.

Pair The owner creates an agent wallet in Brisk and pairs the agent over MCP with a one-time token.
Cap Every wallet is bounded by a per-transaction cap and a rolling 24-hour daily cap — both enforced by the on-chain agent_wallet module, not just the backend.
Spend The agent pays USDC to a 0x address, a @brisk handle or a SuiNS .sui name, or pays a Brisk invoice by its short code. Writes are idempotent, so a retry can never double-send.
Control The owner can pause spending, rotate the token, revoke the agent, or reclaim the funds at any time. Reclaim is permissionless and can only ever pay the owner.

Running on Sui testnet. Caps are fixed 24-hour windows anchored to wallet creation. The most a compromised agent can move is the smaller of its caps, per window, while active.

Trust & rails

Real money, open rails, nothing hidden.

Gasless & self-custodial

Gasless stablecoin transfers at the protocol level. Accounts are created from a Google sign-in but controlled by the user — keys never leave the device. Brisk never holds your money: even the merchant fee is split on-chain, in the payment itself.

Runs on Sui

Payments, Save, merchant identity and agent wallets are Move modules on Sui. Every payment leaves an on-chain receipt you can inspect.

USDC

The balance is real dollars in USDC, not a points system. Pay the exact amount and never hold a volatile token to pay for anything.
