Wallet for interacting with Lappsnet, an experimental network of smart contracts for Lightning Network users.
Visit https://wallet.lappsnet.io/wallet to create an account.
Your browser will generate a private key, which is then encrypted using your security chip. (Screen lock, Yubikey, etc.)
You register a username with Lappsnet Wallet's servers, which stores the encryption key for you. The encrypted private key is stored in your browser.
Finally, back up your private key, secured by a password, in your password manager.
Connecting to dApps is done by signing a message provided by the dapp.
It should look something like nonce: asdfasdfasdf or asdfasdfasdf.
If it looks like it could be a transaction or authorization, DO NOT SIGN.
Otherwise, sign it and you should be redirected to the dApp as a logged in user.
Some dApps may prepare a transaction for you to sign.
Once on Lappsnet Wallet, check the contents of the transaction before signing. THIS IS CRUCIAL!
If the transaction looks fine (destination address, amount, etc.), sign it.
The transaction will be broadcast, and the dapp will be notified.
You can also initiate transactions yourself, from https://wallet.lappsnet.io/wallet.
Choose whether you want to send ESATs (the native currency of Lappsnet), or other tokens.
TIP: Clicking on a token in the list will open a create transaction form for that token!
You can also make contract calls directly from within Lappsnet Wallet.
For this, you must specify the contract address, method, and enter parameters as necessary. Some operations may cost gas, while others may be free. You will be shown an estimated gas cost when confirming.
After entering the contract address, click 'load' to get a list of methods.
Note: Only contracts verified on the explorer can be called this way.
You will see the result of a contract call in a success or error message at the top of the page.
Visit the Redeem page while you are logged into your lappsnet wallet.
You will be asked to provide an invoice where the amount is 100 sats <= amount in sats < (ESAT balance / 1.02)
Note that we charge a 2% fee on withdrawals to cover any potential Lightning Network fees.
Therefore, the withdrawal rate is 100 satoshi : 102 ESAT.
If all routes to your wallet cost more than 2% in fees, the withdrawal will fail.
You can also withdraw to LN while logged in using your recovery key.
Visit the Lappsnet website to purchase ESAT tokens at a rate of 100 ESAT : 100 satoshi.
When you create your wallet, you will be asked to enter a passphrase to encrypt a backup key. Store the encrypted key in your password manager when prompted. (Not the passphrase!)
You can also initiate a fresh backup at any time while logged in.
Unable to log into your wallet? Here is a troubleshooting guide:
If the Lappsnet servers are down, you will have to run a local or cached version of Lappsnet wallet to recover your account.
Use the 'recover account' option, and enter your encrypted private key (saved in your password manager) and passphrase.
Clearing browsing data may delete your local key. In such case, you will not be able to recover your account by authenticating with our servers.
Use the 'recover account' option, and enter your encrypted private key (saved in your password manager) and passphrase.
If the security device (e.g. screen lock, YubiKey) is lost or broken, you will not be able to authenticate with the server. This may include hard resets of your device!
Use the 'recover account' option, and enter your encrypted private key (saved in your password manager) and passphrase.
For maximum safety, make sure your password manager data is stored on multiple devices.
There are 5 operations available, all initiated by a user opening a link in a new tab.
Path: https://wallet.lappsnet.io/wallet
| parameter | required? |
|---|---|
connect=true |
YES |
nonce=<nonce> |
YES |
callbackUrl=<encodeURIComponent(callback url)> |
YES |
callbackMethod=GET |
NO |
Generate a nonce for each wallet connection attempt. The nonce should preferably be human-readable.
The user will follow the link, sign the nonce with their account, and a callback will POST { signature, address } to the specified URL.
If callbackMethod=GET is specified, instead of a POST callback, the user will be redirected to ${callbackUrl}?address=${address}&signature=${signature}.
Path: https://wallet.lappsnet.io/wallet
| parameter | required? |
|---|---|
signTx=true |
YES |
txData=<base64URL encoded tx> |
YES |
callbackUrl=<encodeURIComponent(callback url)> |
no |
callbackMethod=GET |
NO |
The user is asked to sign and broadcast the transaction provided in the txData parameter.
The { txhash } will be POSTed to the callback url if specified.
If callbackMethod=GET is specified, instead of a POST callback, the user will be redirected to ${callbackUrl}?txhash=${<transactionHash>}.
Path: https://wallet.lappsnet.io/wallet
| parameter | required? |
|---|---|
createTx=true |
YES |
amount=<number of tokens, NOT Wei> |
no |
to=<recipient address> |
no |
contractAddress=<ERC20 token contract> |
no |
callbackUrl=<encodeURIComponent(callback url)> |
no |
The user is asked to create a transaction. Defaults to sending ESATs (Lappsnet's native token), unless contractAddress is specified.
All parameters given are entered in the form presented to the user, but the user may edit these values.
Once the user creates, signs, and broadcasts their transaction, { txhash } will be POSTed to callback url if specified.
If callbackMethod=GET is specified, instead of a POST callback, the user will be redirected to ${callbackUrl}?txhash=${<transactionHash>}.
(Contract MUST BE VERIFIED on explorer)
Path: https://wallet.lappsnet.io/wallet
| parameter | required? |
|---|---|
callContract=true |
YES |
contractAddress=<contract address> |
no |
You can send users to make contract calls on their own.
If contractAddress is specified, the user will be shown a list of methods for that contract, with corresponding input fields.
The user provides the necessary inputs, and a gas estimate is given for confirmation.
The chosen method will be called using send() or call() depending on the method. The result is displayed to the user in a success or error banner.
Path: https://wallet.lappsnet.io/wallet
Simply opens the wallet for the user to operate.
