ChangeNOW x Guarda Case Proof – a Wallet Doesn’t Need to Become an Exchange

• Guarda Wallet launched successful 2017 arsenic a self-funded, non-custodial Android wallet built from scratch for a azygous chain. To turn beyond storage, its users needed to swap, buy, and stake wrong the app — without Guarda becoming an speech oregon gathering the infrastructure 1 demands.
• The squad integrated ChangeNOW’s API arsenic its speech layer, with ChangeNOW acting arsenic the superior supplier down Guarda’s swap coverage: liquidity, routing, and pricing sat with ChangeNOW, portion custody stayed successful the user’s hands and the swap itself ne'er near the wallet.
• Guarda present supports 70 large blockchains — astir of that web sum enabled done the ChangeNOW integration — operates successful much than 100 countries, and runs crossed web, desktop, mobile, and a browser extension. ChangeNOW carried the speech side; the wider merchandise trajectory was Guarda’s own.

Storage stopped being a product

For astir of the past decade, a wallet’s occupation was to hold. Keys in, keys safe, keys retired erstwhile needed. That framing nary longer survives interaction with however radical really usage these products. Users justice a wallet by what they tin bash the infinitesimal they unfastened it, not by wherever their assets beryllium portion they’re idle.

When the lone enactment a wallet supports is storage, each swap, purchase, oregon stake becomes a crushed to leave. A wallet built this mode is simply a waypoint betwixt transactions alternatively than the spot transactions happen. An in-wallet speech has moved from a premium diagnostic to a baseline expectation, and the absorbing question is nary longer whether to adhd 1 but wherever the enactment should unrecorded erstwhile you do.

Self-custody went mainstream, and it raised the bar

The displacement has a wide starting point. In 2017, centralized exchanges were losing idiosyncratic spot aft a tally of large hacks, regularisation astir custodial platforms was tightening, and self-custody stopped being a penchant for the technically minded. For a increasing stock of users it became the safer mode to clasp assets astatine all.

That alteration successful behaviour collided with a alteration successful marketplace structure. Assets fragmented crossed chains, and manual navigation betwixt them slowed radical down and raised nonaccomplishment rates astatine precisely the moments they were trying to act. Liquidity scattered crossed bid books, AMM pools, and competing routing systems. Aggregation and astute routing went from precocious tooling to array stakes, due to the fact that nary azygous root could terms a superior commercialized good connected its own. So the barroom roseate doubly astatine once: users wanted custody successful their ain hands, and they wanted to enactment crossed a twelve networks without leaving the app to bash it.

Guarda refused 3 shortcuts

Guarda started that twelvemonth arsenic an Android wallet for Ethereum, built from scratch arsenic a non-custodial merchandise by a squad with nary existing infrastructure, nary merchandise base, and nary extracurricular funding. The hard portion was ne'er the introduction feature. It was trust. A non-custodial architecture can’t support private keys, backup files, oregon idiosyncratic information connected its ain servers, which makes the engineering much demanding than a server-side wallet — and much demanding inactive for a self-funded squad moving against its ain assets limits. The aboriginal enactment got noticed anyway: the Ethereum Classic assemblage picked up the Android wallet, and a Zcash Foundation assistance funded a lightweight ZEC client.

The scaling occupation showed up fast. A abstracted app for each concatenation would person turned the merchandise into a heap of disconnected wallets, truthful the squad needed 1 architecture that could sorb caller assets and caller actions without fracturing. Getting determination meant turning down 3 easier paths, each with a existent cost. A custodial oregon server-side exemplary would person simplified the engineering and fixed up self-custody successful the process. Staying mobile-only would person kept the merchandise focused and ignored each different situation wherever radical negociate crypto. Taking extracurricular superior would person accelerated hiring and added a acceptable of pressures the squad didn’t want. Guarda took the harder way connected each three: self-funded, cross-platform, spot exemplary intact.

That subject is the portion worthy studying. The constraint wasn’t a footnote to the strategy — it was the strategy. A squad that couldn’t spend to physique an speech had to beryllium precise astir what it built and what it plugged in.

The 3rd position: outsource the infrastructure, support the action

Here is wherever the determination gets specific. Guarda made in-app speech a halfway goal. But gathering liquidity and speech operations from the crushed up was precisely the enactment the squad had ruled out. So it drew a enactment astir roadmaps blur: the infrastructure goes out, the enactment stays in.

The speech furniture was integrated done an API — ChangeNOW’s, arsenic the superior supplier — truthful swaps resolved wrong the wallet portion routing, pricing, and liquidity sat extracurricular the team’s operations. Guarda didn’t go an exchange, and it didn’t nonstop its users to one.

That favoritism is casual to collapse, truthful it’s worthy being nonstop astir it. Sending a idiosyncratic to an speech means a redirect retired of the interface, a abstracted account, a 2nd circular of individuality checks, and custody handed to the venue that runs the trade. An embedded swap keeps each of that inside: nary redirect, nary 2nd account, nary transportation of custody, and the interest and the transaction information enactment with the wallet alternatively than the venue. The commercialized inactive settles connected outer rails — but the user, the infinitesimal of action, and the narration ne'er permission the product. Only the plumbing is outsourced. Because the routing is non-custodial, keys ne'er near the user’s power to marque a swap happen, which keeps the wallet’s archetypal committedness intact alternatively than trading it for convenience.

Outsourcing the furniture besides outsourced a load the squad was close to avoid: erstwhile the supplier carries the routing and overmuch of the compliance weight, a wallet adds speech without inheriting the afloat regulatory illustration of one.

The commercialized logic follows from the aforesaid choice. Every enactment a idiosyncratic tin implicit wrong the merchandise deepens the narration and creates a spot to gain without pushing the wallet toward custody — swaps, and aboriginal staking that runs up to astir 20% APY depending connected the asset. Guarda didn’t halt astatine transactions, adding a token generator, an acquisition limb successful Guarda Academy, and the $GRD token, but each of those hung disconnected the aforesaid wallet alternatively than spawning a abstracted app.

Scale arsenic the payoff, and the regularisation worthy keeping

The effect reads arsenic scope alternatively than a database of wins. Guarda present supports 70 large blockchains, with ChangeNOW arsenic the main speech provider down that sum alternatively than the lone one, and it runs successful much than 100 countries crossed web, desktop connected Windows, macOS, and Linux, mobile connected iOS and Android, and a Chrome extension. A single-currency Android app became a spot to hold, swap, buy, and stake from 1 environment. The integration handled the speech layer; it didn’t manufacture the full trajectory, and the honorable mentation of the communicative keeps those 2 things separate.

The acquisition for wallet teams is narrower than “add an exchange.” The wallet that meets the infinitesimal of enactment builds a stronger narration adjacent without holding anyone’s funds. The regularisation Guarda landed connected is the crisp one: don’t go an exchange, but don’t fto different level ain the speech enactment either. Keep the custody exemplary clear, and support the enactment wrong the product.

Which leaves 1 question for anyone moving a wallet today. Of each the transaction intent your users generate, however overmuch are you inactive sending determination other to capture?
