Near DApps Integration
Welcome to MapNode Extension Wallet Developer Guide. This documentation contains guides for developers to get started developing on MapNode Extension Wallet.
To detect whether your browser is running MapNode Extension, please use:
if(window.mapnode || window.mapnode.near || window.near?.isMapNode){
console.log('MapNode Extension is installed!');›
}
Notice: MapNode Extension Testnet is under development and not available now.
Support
window.near only and removal window.web3
To connect MapNode Extension means to access the user's [blockchain - like Near] account(s).
// Connect DApps
window.MapNode.near.connect(<Prefix: optional>,<Contract ID: optional>);
// Get Account
window.MapNode.near.selectedAddress;
// Get Full Accounts State
window.MapNode.near.request({ method: 'near_accountState' });
// Check if DApps connected
window.MapNode.near.isConnected();
To disconnect MapNode Extension, please use:
window.MapNode.near.disconnect()
Once your account is connected, let's start experiencing more functions.
const params = {
contractId: 'token.v2.ref-finance.near',
method: 'ft_balance_of',
args: {
account_id: account
}
}
const balance = await window.MapNode?.near.request({method: 'near_view', params})
console.log("Your near wallet balance ", balance)
const params = {
transactions,
receiver: account
}
const result = await window.MapNode?.near.request({method: 'near_signAndSendTransaction', params})
const balance = await window.MapNode?.near.request({method: 'near_view', params})
console.log("Your near wallet balance ", balance)
