01 · Product two · P2PDEX · white-label

A peer-to-peer desk under your brand, without the custody.

P2PDEX is a fiat-to-crypto marketplace where your users post ads and trade directly: fiat moves bank-to-bank between them, and the crypto sits in an escrow contract you never hold. The ad board, an Express lane, a Block desk, merchant tools, payment rails, disputes and a self-custody wallet ship with it. We put your brand on it, configure your corridors, launch it for you, and hand over the source.

02 · Why

Why operators launch P2PDEX

Book your launch review
01
The operating model of the big P2P desks

Ad board, Express, Block, merchant tiers, appeals and a dispute console: the parts your users expect from the venues they already use, without the custody exposure that comes with them.

02
A lighter licence conversation

You earn a fee on completed trades and hold nothing in between. Bank details show only after escrow, and an award can only ever go to the two addresses fixed at signing. Ask your counsel; we will give them the architecture note.

03
Corridors you choose

USD and EUR with SEPA Instant and domestic wire first, more rails behind them. Eligibility is decided per country, fiat, rail, asset and network, so you open exactly the markets you mean to.

03 · The category

The desks your users trade on today, by the numbers.

The three largest peer-to-peer desks sit inside the three largest exchanges. None publishes its P2P volume on its own, so these are the parents' reported figures.

Logos belong to their owners and are shown for identification only; none of these companies is affiliated with Quantellics.

04 · The board

Your users filter down to the offer they can actually take.

The board reads like the large P2P desks: advertiser, price, available amount and order limits, payment rails, network. Filter by side, asset, fiat, amount, rail and settlement network; sort by best price, completion rate or release speed. Type an amount and the offers that cannot cover it drop out, with the blocking constraint named, so nobody wastes a quote.

For your users
Completed trades, 30-day completion and average release time on every row
Verified-only and online-only filters when it matters
For you
USDC, USDT and ETH against USD and EUR out of the box; your list at launch
Sort and filter rules are configuration, not code

P2PDEX Express: one card that matches an amount to an eligible merchant and previews the quote
05 · Express

Type an amount, meet a merchant.

Express is the one-card path for users who do not want to read a board: enter what you want to pay or receive and get matched to an eligible merchant on best net price, with the counterparty previewed before anything is committed. Flip direction and the amount, fiat, asset and rail survive; change fiat and only an incompatible rail resets.

For your users
One card, one amount, one merchant
Nothing committed until the quote is accepted
For you
Eligibility first, best net price second: your rules decide who can match
Matching never alters the board's filters

06 · Block

A separate lane for the large tickets.

Block trading has its own minimum, its own merchant cohort and its own evidence policy, under the same escrow model. The prototype enforces a fiat-adjusted minimum of 10,000 and restricts the lane to verified merchants. Private block ads for professional merchants are on the plan you receive.

For your users

A P2PDEX quote: price, amount to pay and receive, payment method, settlement network, payment window and the escrow terms to accept
07 · Escrow

Nobody pays until the coin is locked.

Taking an offer freezes a signed quote: parties, fiat amount, crypto amount, token and chain, fee, expiry and dispute policy. The seller funds exactly the order quantity into the escrow contract. Until that lock is confirmed on-chain, the buyer sees "waiting for crypto to be secured" and no bank details at all. That one rule removes the fake-payment play.

For your users
Bank details only after escrow is confirmed
Release only to the fixed buyer address, refund only to the fixed seller address
For you
One audited EVM escrow first: USDC, ETH and eligible USDT routes
EIP-712 signed terms binding chain, contract, addresses, amounts, deadlines, resolver set, nonce and expiry

08 · The order room

One room walks both sides from escrow to release.

An order moves through quoted, funding, payable, paid-claimed, release-pending and completed, with refund-requested, disputed and award-pending branches. "Payment sent" is a buyer claim and never releases by itself. Deadlines live on the server as timestamps and the visible timer is derived from them, so a client clock can never move money.

For your users
A stepper, the payment card, the escrow status and chat in one place
Receipt, CSV export and one feedback event per party on completion
For you
A paid or disputed order never silently expires or refunds
A proposed 24-hour challenge window before an unpaid order refunds

A P2PDEX order in dispute: the frozen trade and the dispute form with its evidence rules
09 · Disputes

A contested transfer freezes the trade. A named quorum decides.

Either side can open a dispute from a payable or paid order. The trade locks, both sides add scoped evidence against response deadlines, and a case owner takes it to award. An award can release to the fixed buyer, refund the seller, or split between the two; it can never pay a third wallet, and silence never settles a case. Your support team is never the one holding the money.

For your users
Reason, timeline, evidence, deadlines and appeal eligibility on one screen
A decision from resolvers disclosed before the order existed
For you
2-of-3 independent resolution signers, separate from support
Quorum signing, appeals and encrypted evidence storage specified for launch

10 · Payment rails

Own-name bank transfers, with windows that fit the rail.

Rails are specific, not a generic "bank transfer" form: SEPA Instant and USD domestic wire first, standard SEPA, FedNow, RTP and ACH credit next. Each rail carries its own payment window. Recipient details are revealed only after escrow, encrypted at rest, kept out of logs and snapshotted to the order so a later edit cannot change live instructions.

For your users
Windows of 15 or 30 minutes on instant rails, 60 on USD wire, 24 hours on standard SEPA
Their own bank, their own name, no card and no cash
For you
Rails, windows and exclusions per corridor

11 · Merchants

Merchants post, price and pause their own liquidity.

A three-stage wizard posts an ad: asset and price, fixed or floating over an index with floor and ceiling; quantity, limits, rails and payment window; conditions, terms and auto-reply. Ads go draft, online, paused, depleted, closed. Pausing stops new orders and keeps open trades; editing creates a new version and accepted terms stay immutable. Liquidity your merchants manage is liquidity you do not have to.

For your users
Completion rate published with its numerator and denominator
Cancellations, non-response and dispute outcomes tracked separately
For you
Merchant bonds, tiers and exposure caps specified; verification simulated in the prototype

12 · Wallet

Balances split by where the money actually is.

The wallet shows personal funds, available trading liquidity, amounts locked in orders, merchant bond and pending, without double counting, per asset and per network. Sending needs destination, amount and gas review before signing; a withdrawal above the available balance is refused. Fiat figures are labelled as estimates, never as withdrawable money, because you never hold any.

For your users
Available and locked per asset, with an activity log
Receive and send with the checks a self-custody wallet should have
For you

13 · Live in four weeks

From launch review to a branded desk in four weeks.

The desk exists. The four weeks go on your brand, your corridors, your rails, your merchants and your escrow.

Week 1
Launch review, then your brand

Forty-five minutes with the engineers who will do the work; you leave with the corridors, the rails, the plan and a number. Then name, colours and logo, and the fiats, assets and networks you open.

Week 2
Your rails and merchants

Rails and payment windows per corridor, your fee, eligibility per country and network, and your first merchants onboarded with their ads.

Week 3
Your escrow, our QA

The escrow contract on the EVM network you choose, and the trade, dispute and wallet flows run against your configuration with your merchants.

Week 4
Launch

The container on your host or ours, TLS, monitoring. Then the source, the contracts, the docs and the keys.

14 · How a trade works

How a trade works, end to end.

01 · Post an ad

Side, asset, network, fiat, fixed or floating price, quantity, limits, rails, payment window and terms. It appears on the opposite side of the board.

02 · Take an offer

Preflight checks eligibility, balance, network, quote expiry and rail support; a signed quote freezes the terms.

03 · Escrow locks

The seller funds the exact quantity into the contract. Only then does the buyer see recipient, amount, rail, reference and deadline.

04 · Pay, verify, release

The buyer transfers from an own-name account and marks paid. The seller checks funds, payer name and amount, then signs the release.

05 · If it goes wrong

Unpaid past deadline: refund request plus a challenge window. Contested: a dispute freezes the trade and a disclosed quorum awards.

Walk through it with the engineers who built it
15 · What you get

Zero custody for you. Full source for your team.

The operator holds no fiat and no user crypto. The contracts are the source of truth for custody, escrow state and permitted payout addresses; the database is a replayable projection that cannot override them. There is no escrow sweep function, and support cannot edit an address to redirect funds. You get the front end, the contracts, the services and the plan.

About the demo

16 · Pricing

One price. Quoted at your launch review.

P2PDEX is sold as a white-label installation plus the customisation that makes it yours. What that costs depends on what you bring and what you want changed, so we give it to you in person: forty-five minutes with the engineers who would do the work, and you leave with a scoped plan, a four-week schedule and one number.
