=======================
|
|
|
|
This package is a collection of quick little ideas, which may be half-baked.
|
|
|
|
If you find a particular feature piques your interest, please feel free to open
|
|
an issue on GitHub to discuss it.
|
|
|
|
Also, if you have any system that requires an object from this package, make sure
|
|
you specify the **exact npm version** in your package.json, as backwards compatibility
|
|
is **NOT** guaranteed for this package; APIs may change and classes may disappear.

**BrainWallet**
|
|
|
|
In general, a Brain Wallet is not recommended, but it is a feature we offered in v3
|
|
and below. It allows a wallet to be described and recovered using a username and a
|
|
password. However, anyone who can guess a username and password can steal the funds,
|
|
and the password cannot be changed. But for backwards compatibility and for simple
|
|
testing, we provide it here.
|
|
|
|
```javascript
|
|
import { BrainWallet } from "@ethersproject/experimental/brain-wallet";
|
|
|
|
// This is optional, but since a Brain Wallet can take 5-10s to generate,
|
|
// helps keep your users informed
|
|
function showProgress(percent) {
|
|
if (percent === 1) {
|
|
console.log("Done.");
|
|
} else {
|
|
console.log("Completed: " + Math.trunc(100 * percent) + "%");
|
|
}
|
|
}
|
|
|
|
// Generate a legacy-compatible Brain Wallet
|
|
BrainWallet.generateLegacy(username, password, showProgress).then((wallet) => {
|
|
console.log(wallet);
|
|
});
|
|
|
|
// Generate a new-style Brain Wallet, which contains a Mnemonic Phrase too
|
|
BrainWallet.generate(username, password, showProgess).then((wallet) => {
|
|
console.log(wallet);
|
|
});
|
|
```
|
|
|
|
**NonceManager**
|
|
|
|
```javascript
|
|
import { NonceManager } from "@ethersproject/experimental/nonce-manager";
|
|
|
|
let signer = "... any way you get a signer ...";
|
|
|
|
// The NonceManager Signer will automatically manage the nonce for you
|
|
// so you may blast the network with as many transactions as you would
|
|
// like. Transactions which have not been mined within XXX timeout and
|
|
// will be rebroadcast; keep in mind that unmined transactions remain
|
|
// in memory.
|
|
const managedSigner = new NonceManager(signer);
|
|
```
|
|
|
|
**Eip1193Bridge**
|
|
|
|
```javascript
|
|
import { Eip1193Bridge } from "@ethersproject/experimental/retry-provider";
|
|
|
|
const signer = "... any way you get an ethers Signer...";
|
|
const provider = "... any way you get an ethers Provider...";
|
|
|
|
const eip1193Provider = new Eip1193Provider(signer, provider);
|
|
|
|
