https://connect.coin98.com
Quick Start For Dapps
NPM Package
Install
npm install --save @coin98-com/connect-sdk
Usage
Dapps Website Connection Example
import { Client, Chain } from '@coin98-com/connect-sdk'
const client = new Client()
client.connect(Chain.fantom, {
logo: "Provide Your App Logo URL",
name: "Your App Name",
url: "Provide Your App URL"
})
React Native Connection (Without Expo) Example
import { Client, Chain } from '@coin98-com/connect-sdk/dist/native'
const client = new Client()
client.connect(Chain.fantom, {
logo: "Provide Your App Logo URL",
name: "Your App Name",
callbackURL: "Your App Uri Schema"
})
Lite without any handler (Example With React Native)
import { Client, Chain } from '@coin98-com/connect-sdk/dist/lite'
import { Linking } from 'react-native'
const client = new Client({
callback(cUrl){
Linking.openURL(cUrl);
}
})
client.connect(Chain.fantom, {
logo: "Dapps Logo URL",
name: "Dapps Name",
callbackURL: "Application URI Schema"
})
Common API
