KAVA DApps Integration
Welcome to Coin98 Extension Wallet Developer Guide. This documentation contains guides for developers to get started developing on Coin98 Extension Wallet.
To detect whether your browser is running Coin98 Extension, please use:
if (window.coin98) {
console.log('Coin98 Extension is installed!');
}
To connect Coin98 Extension means to access the user's [blockchain - like KAVA] account(s).
// Connect only
const connection = window.coin98.cosmos('<chain: String>');
// Connect & get accounts
connection.request({ method: 'cosmos_accounts' });
// Check whether dapp connected or not
connection.isConnected();
Currently chains support: ['terra','kava']
To disconnect Coin98 Extension, please use:
connection.disconnect();
Once your account is connected, let's start experiencing more functions.
return
Promise<Array[String]>
- If wallet can not be found, return
[]
instead ofthrow Error
connection.request({ method: 'cosmos_accounts' }).then((accounts) => {
if (accounts[0]) {
// Do something with accounts
} else {
// Wallet not found
}
});
return
Promise<{data: Boolean}>
const hasWallet = connection.request({ method: 'has_wallet', params: ['<chain>'] });
return:
Promise<Hash>
const signature = connection.request({
method: 'cosmos_execute',
params: ['<contractAddres: string>', '<executeMsg: string>'],
});
// Example Execute Contract
let cw20Contract =
'juno10rktvmllvgctcmhl5vv8kl3mdksukyqf2tdveh8drpn0sppugwwqjzz30z';
let execMsg =
'{"transfer":{"amount":"1","recipient":"juno1cx4nq77x3unvl2xsa9fmm9drxkexzkjnzwt2y7"}}';
const response = await connection.request({
method: 'cosmos_execute',
params: [cw20Contract, execMsg],
});
Currently we only support some action event from wallet extension
connection.on('event_name', callback);
//Example
connection.on('close', () => window.location.reload());
connection.on('accountsChanged', () => window.location.reload());
Events | Trigger |
---|---|
accountsChanged | Receive when active account changed in Extension |
networkChanged | Receive when active network changed in Extension |
chainChanged | Receive when active chain changed in Extension |
