API Reference
A list of Leap Connect Wallet methods
The
window.leap.enable(chainIds)
method redirects to the extension login page if it is locked. If the user hasn't permitted the webpage, it will ask the user to enable the webpage to access Leap.window.leap.enable(chainId: string | Array<string>)
// you can pass a list of chainIds to get approval for multiple chains in one request
window.leap.enable(['chainId1', 'chainId2'])
Note: In a case where multiple wallets are imported, users can select the wallet/wallets that are supposed to be enabled.
If the webpage has permission and Leap wallet is unlocked, this function will return the address and public key in the following format:
interface Key {
name: string;
algo: string;
pubKey: Uint8Array;
address: Uint8Array;
bech32Address: string;
isNanoLedger: boolean;
}
window.leap.getKey(chainId: string): Promise<Key>
Like
signAmino
method of CosmJS OfflineDirectSigner, however, Leap's signAmino
function takes the chain-id as a required parameter. Signs Amino-encoded StdSignDoc.interface SignOptions {
// If set to true the wallet will not override fees specified in the signDoc.
preferNoSetFee: boolean
}
signAmino(chainId: string, signer: string, signDoc: StdSignDoc, signOptions?: SignOptions): Promise<AminoSignResponse>
Like
signDirect
method of CosmJS OfflineDirectSigner, however, Leap's signDirect
function takes the chain-id as a required parameter. Signs Proto-encoded StdSignDoc.interface SignDoc {
bodyBytes?: Uint8Array | null;
authInfoBytes?: Uint8Array | null;
chainId?: string | null;
accountNumber?: Long | null;
}
interface SignOptions {
// If set to true the wallet will not override fees specified in the signDoc.
preferNoSetFee: boolean
}
signDirect(chainId:string, signer:string, signDoc: SignDoc, signOptions?: SignOptions): Promise<DirectSignResponse>
signArbitrary(
chainId: string,
signerAddress: string,
data: string | Uint8Array
): Promise<StdSignature>;
await window.leap.signArbitrary(chainId, signerAddress, 'hello')
Webpages can use this function to delegate the broadcasting of the transaction to LCD endpoints configured in the leap wallet. If the broadcast is successful, this method will return the transaction hash. Otherwise, it will throw an error.
sendTx(
chainId: string,
tx: Uint8Array,
mode: BroadcastMode
): Promise<Uint8Array>;
Leap’s API is similar to Keplr's to keep the integration of leap for the dApp as easy as possible.
import { GasPrice, SigningStargateClient } from '@cosmjs/stargate'
await window.leap.enable(chainId);
const signOptions = {
// set this to true to prevent leap from overriding the fees.
preferNoFeeSet: false
}
const offlineSigner = window.leap.getOfflineSigner(chainId, signOptions);
const accounts = await offlineSigner.getAccounts();
const rpcUrl = "" // Replace with a RPC URL for the given chainId
const signingStargateClient = await SigningStargateClient.connectWithSigner(
rptycUrl,
offlineSigner,
{
gasPrice: GasPrice.fromString("0.0025ujuno"),
}
)
await window.leap.isConnected(chainId) // returns boolean
await window.leap.disconnect(chainId) // returns boolean
const supportedChains = await window.leap.getSupportedChains()
