Custody changed on live balances, with no funds lost

Panther Wallet moved from a non-custodial to a custodial model under real balances. The wallet platform is built and run by our team.

Pick your product. See the wallet inside it.

Eight kinds of product we get asked about. Each one keeps its own app, its own look, its own accounts and its own records.

Neobank or fintech

Crypto balances next to fiat, in the same app.

Your customer opens the bank app they already use and finds a crypto account under their main account.

What we connect

  • The same login and the KYC you have already done
  • Balances written to your core system as they change
  • Limits and approvals from your back office

First stage A deposit that lands as a balance in the customer's account

Marketplace or platform

Sellers paid in stablecoins, as their orders settle.

Your seller opens the dashboard they already work in and sees the payout building up, order by order.

What we connect

  • Seller accounts, with one login
  • Payouts written to your order system as they settle
  • Mass payouts from one balance, with a daily report for finance

First stage One seller paid out, end to end

Game or community

A token your players can earn, hold and spend without leaving.

Your player opens the game they already play and finds a wallet behind their account, with no seed phrase at sign-up.

What we connect

  • Player accounts; the wallet is created behind the login they have
  • Rewards credited by your game server through the API
  • Shop purchases and limits that stay under your rules

  • Deposits credited to the player balance as they confirm
  • Cash-out limits and approvals from your payments team

  • Earnings written to your billing system as they arrive
  • Payout rules and minimums that you set

First stage One tip received and withdrawn, end to end

Loyalty programme

Your member opens the programme they already belong to and converts points to a stablecoin, at the rate you set.

What we connect

  • Member accounts and tiers, unchanged
  • The conversion rate, caps and expiry rules from your side
  • Every conversion written to your points ledger

One wallet. Three places to open it.

Same account, same balance, whichever one your users pick. Start with one; add the others when you need them.

More than a balance

Six things the wallet does inside your product. Four are ready today; two we build to your rules.

Wallet balanceReady

Hold, send and receive on the networks you choose, custodial or non-custodial. Every change is written back to your records.

SwapReady

Your users exchange one asset for another inside your product, at a live rate, without leaving it.

StakingReady

Users earn yield on what they hold. Rewards are tracked and paid automatically, through a licensed partner.

Crypto cardReady

Your users pay in shops and online from the balance in the wallet. Issued under your brand, through a licensed card partner. We do not issue the card.

TradingBuilt for you

Buy and sell inside the wallet, wired to the liquidity and the rules you choose. We have run an exchange in production ourselves.

Prediction marketsBuilt for you

Users take a position on an outcome, and the market settles on-chain. Built to your market rules.

Where the licence draws the line
  • Trading and prediction markets depend on what your licence allows in your market.
  • We say where the line is on the first call.

Three steps, each at a fixed price

One call, one integration, then we run it with you. The integration is priced after the call and before any work starts, so the figure does not move.

  1. Discovery call

    Free. We look at what you run, agree where the wallet should live and who holds the keys. You leave with a one-page integration map and a fixed price.

  2. Integration

    We connect the wallet to your login, your accounts and your records, one flow at a time. Each flow is accepted in staging against criteria both sides signed, then we launch.

  3. Support

    After launch we run the infrastructure and the people behind it: nodes, monitoring, updates, and a team that answers when something looks wrong. The monthly terms are part of the same fixed-price offer.

What moves the price
  • How many of your systems it connects to
  • Where the wallet shows
  • Who holds the keys
  • Whether there is a wallet to migrate

Two ways to hold keys

Choose who holds the keys. Both models are live. The delivery model (SaaS, on-premise or SDK) is the same as for the ready-made app.

Custody

Custodial

Your platform manages keys and balances centrally. A simpler experience and easy recovery for your users. Usually a licence question for you.

Custody

Non-custodial

Your users hold their own keys. Less liability for you, and full self-custody for them. Recovery is a design you get right before launch.

Both are live on every delivery model. Moving between them later is a project; we have done it on live balances with no funds lost.

Delivery models: SaaS, on-premise, SDK

Custom wallet questions, answered

What product teams ask before adding a wallet to what they already run. If yours is not here, ask on the discovery call.

What is custom crypto wallet development?
A crypto wallet built into a product you already run: a neobank, a marketplace, a game, an exchange, a loyalty programme. Your users keep their login and their account; the wallet appears inside the app as a new screen, and every balance change is written back to your records. We start from a wallet that already runs in production, so the work is the integration.
Do my users need a new app or a new login?
No. The wallet is created behind the login your users already have, in the app they already open. There is no seed phrase at sign-up unless you choose non-custodial wallets, and nothing new to download. If you prefer a separate companion app under your brand, that is a delivery option too.
Which of our systems does the wallet connect to?
Four, as a rule: your login and accounts, so a wallet exists for each user; your KYC, so verification is reused; your ledger or records, so every deposit, withdrawal and balance change is reported to the system you already trust; and your support tools, so your team sees wallet status where they work. How many of these you connect is the main thing that moves the price.
Can we keep the KYC we already do?
Yes. A user verified in your product is verified in the wallet. We read the status from your system; we do not run a second onboarding. Limits and approvals stay in your back office.
Who holds the keys?
Your choice, and both are live. Custodial: keys are managed centrally, recovery is simple for your users, and it is usually a licence question for you. Non-custodial: your users hold their own keys, less liability for you, and recovery is a design decision taken before launch. We settle this on the discovery call, because moving between the two later is a project of its own; we have done it on live balances with no funds lost.
We already have a wallet. Can you replace it?
Yes. The migration is its own stage, priced after the discovery call like everything else. Balances move under a plan both sides sign, with a checkpoint before anything is switched over. Whether there is a wallet to migrate is one of the four things that move the price.
Can we add swap, staking, a card or trading later?
Swap, staking and a branded crypto card are ready and run through licensed partners; they can be switched on at launch or added later. Trading and prediction markets are built to your rules and depend on what your licence allows in your market. We say where the line is on the first call. The card is issued by a licensed partner; we do not issue it.
How long does the integration take?
It depends on how many of your systems the wallet connects to and whether there is a wallet to migrate, so we do not quote a number before we have looked. What we do promise: the first flow is working in staging and accepted before the rest is built, and the dates come with the fixed price after the discovery call.
How much does custom crypto wallet development cost?
The price is fixed and agreed after a free discovery call, with acceptance criteria both sides sign. What moves it: how many of your systems the wallet connects to, where the wallet shows, who holds the keys and whether there is a wallet to migrate. After launch there is a monthly fee for the infrastructure and the people who run it, stated in the same offer. A security review before mainnet is included. A third-party security audit is not. What moves the price across the market, from custody to chains and security depth, is in Crypto wallet development cost.

Tell us what you run

The product and where the wallet should live in it. If a custom build is the wrong shape, we will say so on the first call.
