Amazing Transaction UX. Without a Hassle.

// and use standard tooling. This one line of
// code injects Dev3 between your app and Web3
// provider – giving you all the best features of Dev3
// while allowing you to keep writing classic Web3 vode
function domFinishedLoading() {
   Dev3.attach(‘apikey’, ‘projectID’)

// For developers looking for an easy & secure way
// to add Web3 functionality to their app. Not compatible
// with standard Web3 tooling.

nft = await sdk.getContractByAlias(‘my-nft’)
   const action = await nft.buildAction(‘mint’, [1])
   const result = await action.present()
