+## Dependencies
+
+### Required
+
+- [NodeJS](https://nodejs.org)
+- [Yarn](https://yarnpkg.com/getting-started/install) (`npm install -g yarn`)
+- [Deno](https://deno.land/#installation)
+
+### Optional (Recomended)
+
+- [nvm](https://github.com/nvm-sh/nvm#installing-and-updating)
+- [docker-compose](https://docs.docker.com/compose/install/)
+- [MetaMask](https://metamask.io/)
+
+## Setup
+
+Run the repo setup script
+```sh
+./setup.ts
+```
+
+Then choose to target either a local Hardhat node or the Arbitrum Testnet.
+
+### Local
+
+Start a local Hardhat node for RPC use.
+```sh
+cd ./contracts
+yarn hardhat node
+```
+
+You can use any two of the private keys displayed (PK0 & PK1) to update these values in `./aggregator/.env`.
+```
+...
+PRIVATE_KEY_AGG=PK0
+PRIVATE_KEY_ADMIN=PK1
+...
+```
+
+Set this value in `./contracts/.env` (This mnemonic is special to hardhat and has funds).
+```
+...
+DEPLOYER_MNEMONIC="test test test test test test test test test test test junk"
+...
+```
+
+Deploy the PrecompileCostEstimator contract.
+```sh
+yarn hardhat run scripts/0_deploy_precompile_cost_estimator.ts --network gethDev
+```
+Copy the address that is output.
+
+Update `./contracts/contracts/lib/hubble-contracts/contracts/libs/BLS.sol`'s `COST_ESTIMATOR_ADDRESS` to the value of that address;
+```solidity
+...
+address private constant COST_ESTIMATOR_ADDRESS = 0x57047C275bbCb44D85DFA50AD562bA968EEba95A;
+...
+```
+
+Deploy all remaining `bls-wallet` contracts.
+```sh
+yarn hardhat run scripts/deploy_all.ts --network gethDev
+```
+
+### Arbitrum Testnet (Rinkeby Arbitrum Testnet)
+
+You will need two ETH addresses with Rinkeby ETH and their private keys (PK0 & PK1) for running the aggregator. It is NOT recommended that you use any primary wallets with ETH Mainnet assets.
+
+You can get Rinkeby ETH at https://app.mycrypto.com/faucet, and transfer it into the Arbitrum testnet via https://bridge.arbitrum.io/. Make sure when doing so that your network is set to Rinkeby in MetaMask.
+
+Update these values in `./aggregator/.env`.
+```
+RPC_URL=https://rinkeby.arbitrum.io/rpc
+...
+NETWORK_CONFIG_PATH=../contracts/networks/arbitrum-testnet.json
+PRIVATE_KEY_AGG=PK0
+PRIVATE_KEY_ADMIN=PK1
+...
+```
+
+And then update this value in `./extension/.env`.
+```
+...
+
+DEFAULT_CHAIN_ID=421611
+...
+```
+
+## Run
+
+```sh
+docker-compose up -d postgres # Or see local postgres instructions in ./aggregator/README.md#PostgreSQL
+cd ./aggregator
+./programs/aggregator.ts
+```
+
+In a seperate terminal/shell instance
+```sh
+cd ./extension
+yarn run dev:chrome # or dev:firefox, dev:opera
+```
+
+### Chrome
+
+1. Go to Chrome's [extension page](chrome://extensions).
+2. Enable `Developer mode`.
+3. Either click `Load unpacked extension...` and select `./extension/extension/chrome` or drag that folder into the page.
+
+### Firefox
+
+1. Go to Firefox's [debugging page](about:debugging#/runtime/this-firefox).
+2. Click `Load Temporary Add-on...`.
+3. Select `./extension/extension/firefox/manifest.json`.
+
+## Testing/using updates to ./clients
+
+### extension
+```sh
+cd ./contracts/clients
+yarn build
+yarn link
+cd ../extension
+yarn link bls-wallet-clients
+```

+You will need to push up an `@experimental` version to 'bls-wallet-clients' on npm and update the version in `./aggregtor/src/deps.ts` until a local linking solution for deno is found. See https://github.com/alephjs/esm.sh/discussions/216 for details.
+
+In `./contracts/clients` with your changes:
+```
+yarn publish-experimental
+```
+Note the `x.y.z-abc1234` version that was output.
+
+Then in `./aggregtor/deps.ts`, change all `from` references for that package.
+```typescript
+...
+} from "https://esm.sh/bls-wallet-clients@x.y.z-abc1234";

 # Aggregator Proxy
 
-[![npm version](https://img.shields.io/npm/v/bls-wallet-aggregator-proxy)](https://www.npmjs.com/package/bls-wallet-aggregator-proxy)

-This package makes it easy to provide an aggregator by proxying another. The primary use-case is to expose a free aggregator based on one that requires payment by augmenting the bundles with transactions that pay `tx.origin`.

-# Local Development
-
-These steps will setup this repo on your machine for local development for the majority of the components in this repo.
-By default the extension will connect to contracts already deployed on Arbitrum Nitro testnet and a public Aggregator running on https://arbitrum-goerli.blswallet.org/
-If you would like to target a remote network instead, add the addtional steps in [Remote Development](./remote_development.md) as well.
-
-## Dependencies
-
-### Required
-
-- [NodeJS](https://nodejs.org)
-- [Yarn](https://yarnpkg.com/getting-started/install) (`npm install -g yarn`)

-```sh
-nvm install
-```
-
-Run the repo setup script
-```sh
-./setup.ts
-```
-
-Then choose to target either a local Hardhat node or the Arbitrum Testnet. If you choose to run on Arbitrum Goerli skip ahead until tests.
-
-### Chain (RPC Node)
-
-Start a local Hardhat node for RPC use.
-```sh
-cd ./contracts
-yarn hardhat node
-```
-
-### Contracts
-
-Fund the `create2Deployer`.
-```sh
-yarn hardhat fundDeployer --network gethDev
-```
-
-Deploy all `bls-wallet` contracts.
-```sh
-yarn hardhat run scripts/deploy_all.ts --network gethDev
-```
-
-## Aggregator
-
-make these changes in aggregator > .env
-

-2. Enable `Developer mode`.
-3. Either click `Load unpacked extension...` and select `./extension/extension/chrome` or drag that folder into the page.
-
-### Firefox
-
-1. Go to Firefox's [debugging page](about:debugging#/runtime/this-firefox).
-2. Click `Load Temporary Add-on...`.
-3. Select `./extension/extension/firefox/manifest.json`.
-
-### Tests
-See each components `README.md` for how to run tests.
-
-## Testing/using updates to ./clients
-
-### extension
-```sh
-cd ./contracts/clients
-yarn build
-yarn link
-cd ../extension
-yarn link bls-wallet-clients
-```
-
-If you would like live updates to from the clients package to trigger reloads of the extension, be sure to comment out this section of `./extension/weback.config.js`:
-```javascript
-...
-module.exports = {
-  ...
-  watchOptions: {
-    // Remove this if you want to watch for changes
-    // from a linked package, such as bls-wallet-clients.
-    ignored: /node_modules/,
-  },
-  ...
-};
-```
-
-### aggregator
-
-You will need to push up an `@experimental` version to 'bls-wallet-clients' on npm and update the version in `./aggregtor/src/deps.ts` until a local linking solution for deno is found. See https://github.com/alephjs/esm.sh/discussions/216 for details.
-You will need write access to the npmjs project to do this. You can request access or request one of the BLS Wallet project developers push up your client changes in the `Discussions` section of this repo.
-
-In `./contracts/clients` with your changes:
-```
-yarn publish-experimental
-```
-Note the `x.y.z-abc1234` version that was output.
-
-Then in `./aggregtor/deps.ts`, change all `from` references for that package.
-```typescript
-...
-} from "https://esm.sh/bls-wallet-clients@x.y.z-abc1234";
-...

-# Remote Development
-
-These steps will setup this repo on your machine for targeting a remote chain, such as an EVM compatible L2.
-
-Follow the instructions for [Local Development](./local_development.md), replacing the sections titled `Chain` and `Contracts` with the steps below.
-
-## Deploy Contracts
-
-### Deployer account
-
-BLS Wallet contract deploys use `CREATE2` to maintain consistent addresses across networks. As such, a create2 deployer contract is used and listed in `./contracts/.env` under the environment variables `DEPLOYER_MNEMONIC` & `DEPLOYER_SET_INDEX`. The HD address will need to be funded in order to deploy the contracts.
-
-If you do not need consistent addresses, for example on a local or testnet network, you can replace the `DEPLOYER_MNEMONIC` with another seed phrase which already has a funded account.
-
-### Update hardhat.config.ts
-
-If your network is not listed in [hardhat.config.ts](../contracts/hardhat.config.ts), you will need to add it.
-
-### Precompile Cost Estimator
-
-If your network does not already have an instance of the [BNPairingPrecompileCostEstimator contract](../contracts/contracts/lib/hubble-contracts/contracts/libs/BNPairingPrecompileCostEstimator.sol), you will need to deploy that.
-
-```sh
-cd ./contracts
-yarn hardhat run scripts/0_deploy_precompile_cost_estimator.ts --network YOUR_NETWORK
-```
-Copy the address that is output.
-
-Update `./contracts/contracts/lib/hubble-contracts/contracts/libs/BLS.sol`'s `COST_ESTIMATOR_ADDRESS` to the value of that address if it is different:
-```solidity
-...
-address private constant COST_ESTIMATOR_ADDRESS = YOUR_NETWORKS_PRECOMPILE_COST_ESTIMATOR_ADDRESS;
-...
-```
-
-### Remaining Contracts
-
-Deploy all remaining `bls-wallet` contracts.
-```sh
-cd ./contracts # if not already there
-yarn hardhat run scripts/deploy_all.ts --network YOUR_NETWORK
-```
-
-A network config file will be generated at `./contracts/networks/local.json`. You should rename it to match your network.
-
-```sh
-mv ./networks/local.json ./networks/your-network.json
-```
-
-This file can be commited so others can use your deployed contracts.
-
-## Remote RPC
-
-### Aggregator
-
-Update these values in `./aggregator/.env`.
-PK0 & PK1 are private keys for funded accounts on your network/chain.
-```
-RPC_URL=https://your.network.rpc
-...
-NETWORK_CONFIG_PATH=../contracts/networks/your-network.json
-PRIVATE_KEY_AGG=PK0
-PRIVATE_KEY_ADMIN=PK1
-...
-```
-
-### Extension
-
-Check the [controller constants file](../extension/source/Controllers/constants.ts) to see if your network is already added. If not, you will need to add chainid & supported networks entries for your network/chain. These changes can be committed.
-
-Then, update this value in `./extension/.env`.
-```
-...
-
-DEFAULT_CHAIN_ID=YOUR_CHAIN_ID
-...
-```
-
-## Run
-
-Follow the remaing instruction in [Local Development](./local_development.md) starting with the `Run` section.
-
-## Example: Arbitrum Testnet (Rinkeby Arbitrum Testnet)
-
-You will need two ETH addresses with Rinkeby ETH and their private keys (PK0 & PK1) for running the aggregator. It is NOT recommended that you use any primary wallets with ETH Mainnet assets.
-
-You can get Rinkeby ETH at https://app.mycrypto.com/faucet, and transfer it into the Arbitrum testnet via https://bridge.arbitrum.io/. Make sure when doing so that your network is set to Rinkeby in your web3 wallet extension, such as MetaMask.
-
-Update these values in `./aggregator/.env`.
-```
-RPC_URL=https://rinkeby.arbitrum.io/rpc
-...
-NETWORK_CONFIG_PATH=../contracts/networks/arbitrum-testnet.json
-PRIVATE_KEY_AGG=PK0
-PRIVATE_KEY_ADMIN=PK1
-...
-```
-
-And then update this value in `./extension/.env`.
-```
-...
-
-DEFAULT_CHAIN_ID=421611

-
-You can find current contract deployments in the [contracts networks folder](../contracts/networks/).
-If you would like to deploy locally, see [Local development](./local_development.md).
-If you would like to deploy to a remote network, see [Remote development](./remote_development.md).

-## Send a transaction
-
-```typescript
-import { readFile } from "fs/promises";
-
-
-// Instantiate a provider via browser extension, such as Metamask 
-const provider = providers.Web3Provider(window.ethereum);
-// Or via RPC
-const provider = providers.JsonRpcProvider();
-// See https://docs.ethers.io/v5/getting-started/ for more options
-
-// Get the deployed contract addresses for the network.
-// Here, we will get the Arbitrum testnet.
-// See local_development.md for deploying locally and
-// remote_development.md for deploying to a remote network.
-const netCfg = await getConfig("../contracts/networks/arbitrum-testnet.json", async (path) => readFile(path));
-
-const privateKey = "0x...";
-
-// Note that if a wallet doesn't yet exist, it will be
-// lazily created on the first transaction.
-const wallet = await BlsWallerWrapper.connect(

-
-const recipientAddress = "0x...";
-const nonce = await wallet.Nonce();
-// All of the actions in a bundle are atomic, if one
-// action fails they will all fail.

-# Use BLS Wallet In Your L2 dApp
-
-This guide will show you how to use BLS Wallet in your L2 dApp (Layer 2 decentralized application) so you can utilize multi-action transactions.
-
-## Download, Install, & Setup Quill
-
-[Quill](../extension/) is a protoype browser extension wallet which intergrates [bls-wallet-clients](../contracts/clients/) to communicate with the BLS Wallet smart contracts & transaction aggregator. It supports most of the functionality in [EIP-1193](https://eips.ethereum.org/EIPS/eip-1193).
-
-Currently, we have the contracts deployed to the networks/chains listed [here](https://github.com/web3well/bls-wallet/tree/main/contracts/networks). If your desired network isn't there, you can use the [Remote Development](./remote_development.md) contract deployment intrsuctions or request a network deploy by [opening an issue](https://github.com/web3well/bls-wallet/issues/new) or [starting a discussion](https://github.com/web3well/bls-wallet/discussions/new).
-
-Below are the instructions for 2 ways you can add Quill to your browser.
-
-### Prebuilt
-
-Go to the [releases page](https://github.com/web3well/bls-wallet/releases) and scroll down to the latest release. In the `Assets` section, download the extension for either Chrome, Firefox, or Opera. To install, simply drag and drop the file into your browser on the extensions page or follow instructions for installing extensions from a file for your browser.
-
-### From Repo
-
-Follow the instructions in either [Local Development](./local_development.md) or [Remote Development](./remote_development.md) to setup this repo and install Quill.
-
-### Setup Quill
-
-After installing the extension, Quill will auto-open and guide you through the setup process.
-
-## Connect Your dApp to Quill
-
-Next, connect your dApp to Quill just like you would any other extension wallet.
-
-`ethers.js`
-```typescript
-import { providers } from 'ethers';
-
-const provider = providers.Web3Provider(window.ethereum);
-
-await window.ethereum.request({ method: "eth_accounts" });
-```
-
-Or similarly with [web3modal](https://github.com/WalletConnect/web3modal#usage) or [rainbow-connect](https://rainbowkit.vercel.app/docs/installation#configure)
-
-## Send Multi-Action Transaction
-
-Finally, you can populate & send your multi-action transaction. In the following example, we will do an approve & swap with a DEX (decentralized exchange) in one transaction.
-
-### Check that window.ethereum Supports Multi-Action Transactions
-
-Since any browser extension wallet could be used, make sure that it is Quill before allowing a multi-action transaction.
-
-```typescript
-const areMultiActionTransactionSupported = !!window.ethereum.isQuill;
-// Branch here depending on the result
-if (areMultiActionTransactionSupported) {
-  ...
-}
-```
-
-### Populate the Transactions (Actions)
-
-First, we will populate the transactions (actions) we want to send.
-
-```typescript
-// Get the signer and connect to the contracts.
-//
-// If you want the contracts to always have write access
-// for a specific account, pass the signer in as the
-// provider instead and skip calling connect on them.
-const signer = provider.getSigner();
-
-const erc20Contract = new ethers.Contract(erc20Address, erc20Abi, provider);
-const dexContract = new ethers.Contract(dexAddress, dex20Abi, provider);
-
-// Populate the token approval transaction.
-const approveTransaction = await erc20Contract
-  .connect(signer)
-  .populateTransaction.approve(dexAddress, amount);
-
-// Populate the token swap transaction.
-const swapTransaction = await dexContract
-  .connect(signer)
-  .populateTransaction.swap(erc20Address, amount, otherERC20Address);
-```
-
-### Send the Transaction
-
-Then, send the populated transactions.
-
-Quill's [eth_sendTransaction](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_sendtransaction) accepts a modified `params` property into which more than one transaction object can be passed in. [Make sure window.ethereum can accept multiple transactions](#check-that-windowethereum-supports-multi-action-transactions) before passing more than one in.
-
-```typescript
-const transactionHash = await window.ethereum.request({
-  method: "eth_sendTransaction",
-  params: [approveTransaction, swapTransaction],
-});
-
-const transactionReceipt = await provider.getTransactionReceipt(transactionHash);
-// Do anything else you need to with the transaction receipt.
-```
-
-You also can still send normal one-off transactions as you normally would, and still get the gas saving benefits of having your transaction aggregated with other transactions.
-
-```typescript
-const transferTransaction = await erc20Contract
-  .connect(signer)
-  .approve(otherAddress, amount);
-
-await transferTransaction.wait();
-```
-
-## How Does This All Work?
-
-See the [System Overview](./system_overview.md) for more details on what's happening behind the scenes.
