Cross-chain swaps, signed on KeepKey.
The SwapKit SDK connects KeepKey hardware wallets out of the box, so your users can swap across chains and confirm every transaction on their device.
01
Self-custody without leaving your app.
KeepKey is a cold-storage, self-custody hardware wallet. With SwapKit, users connect it in your app, pick a swap and approve it on the device. Keys never leave the KeepKey.
02
In KeepKey's words.
“SwapKit lets you build on THORChain easily, and now it will let you integrate KeepKey into your dApp easily as well. I don’t know how you could integrate THORChain without SwapKit, and frankly I wouldn’t want to find out!” KeepKey contributors
