Guarda adds in-wallet swaps via ChangeNOW API
Guarda integrated ChangeNOW’s API to add in‑wallet swaps, buys and staking while keeping users’ private keys on their devices and avoiding custodial exchange operations.
Guarda began in 2017 as a self-funded, non-custodial Android wallet built for Ethereum. The team sought to add swap, buy and staking functions inside the app without becoming an exchange.
To add those functions Guarda integrated the ChangeNOW API. ChangeNOW supplies liquidity, routing and pricing. Guarda routes swap requests through the API so trades complete inside the wallet while private keys remain on users’ devices.
The integration keeps users in the wallet interface and avoids redirects to external trading platforms. Trades do not require separate exchange accounts or additional identity checks because custody of private keys remains with each user.
Guarda supports about 70 major blockchains and operates in more than 100 countries. The product runs on web, desktop (Windows, macOS, Linux), mobile (iOS and Android) and as a Chrome extension. Most of the wallet’s multi-chain swap coverage is supplied through the ChangeNOW connection.
The team opted against three alternatives: a custodial server-side design that would hold user keys, a mobile-only product that would limit platform reach, and taking outside investment that would change control. The company remained self-funded and cross-platform in its approach.
Market factors affected the decision. Several exchange hacks and tighter regulation led more users to prefer self-custody. At the same time, liquidity spread across order books and automated market maker pools, increasing demand for aggregation and smart routing services that the ChangeNOW API provides.
Guarda also offers a token generator, an educational program called Guarda Academy and a native GRD token, all attached to the same wallet. The wallet supports staking, with yields that vary by asset and can reach roughly 20% APY in some cases.
Because ChangeNOW provides the exchange layer, Guarda does not take on the full operational and regulatory functions of an exchange. Swap execution still settles on external blockchains while user keys remain under user control.
