## Usage
### Pre Requisites
Before installing, create a `.env` file and set the authentication method and other env criteria as in `.env.example`.
You can authenticate with either:
- `PRIVATE_KEY` — a raw hex private key (e.g. `0x123...`). Takes priority if both are set.
- `MNEMONIC` — a BIP-39 compatible 12-word mnemonic phrase. Used as fallback when `PRIVATE_KEY` is not set.
Before installing, create a `.env` file and set a BIP-39 compatible mnemonic and other env criteria as in `.env.example`.
### Install

import localhostDeploys from "p2pix-smart-contracts/deploys/localhost.json";
```
## Deployment (Hardhat Ignition)
## Deploying to local environment
Deployments are orchestrated by
[Hardhat Ignition](https://hardhat.org/ignition). Each module declares its
contracts; Ignition handles ordering, idempotency, and per-network state
under `ignition/deployments/`.
### Modules
- `ignition/modules/MockToken.ts` — ERC20 mock used in dev / testnets.
- `ignition/modules/Reputation.ts` — Reputation + Multicall.
- `ignition/modules/P2PIX.ts` — production deploy (no MockToken). Token
addresses passed via parameters (`tokens` + `allowed`).
- `ignition/modules/P2PIXWithMock.ts` — dev/test deploy. Wires Reputation +
MockToken and deploys P2PIX.
### Per-network parameters
Network-specific values (e.g. `defaultBlocks`, `validSigners`, MockToken
`supply`) live in `ignition/parameters/<network>.json`. Only
`localhost.json` is checked in; copy it to e.g. `sepolia.json` and set the
network values before running the deploy script.
### Local environment
On the first terminal:
On the first teminal, use the following command and import some wallets to your Metamask, then connect to the network pointed:
```sh
yarn hardhat node
```
On the second terminal:
On the second teminal, run the following commands:
```sh
yarn deploy:mock --network localhost --parameters ignition/parameters/localhost.json
yarn deploy1:localhost
yarn deploy2:localhost
```
Addresses for every deployed contract are written to
`ignition/deployments/chain-31337/deployed_addresses.json` (this path is
gitignored — local-only state).
**_NOTE_:** The second script transfers 2M tokens to the first wallet of the node.
To use the P2Pix smart contract first transfer some of the tokens to other wallets.
### Testnets
## Deploying to testnets
Deploy to Ethereum's Goerli testnet:
```sh
yarn deploy:mock --network sepolia
yarn deploy1:goerli
yarn deploy2:goerli
```
Requires the matching `ignition/parameters/sepolia.json` and the relevant
API keys in `.env`.
Deploy to Polygon's Mumbai testnet:
### Production (real tokens)
Use the `P2PIX` module when the target network already has the ERC20
tokens you want P2PIX to support — no MockToken is deployed.
1. Copy `ignition/parameters/prod.example.json` to
`ignition/parameters/<network>.json` and set:
- `defaultBlocks`, `validSigners`
- `tokens` — array of ERC20 addresses on the target network
- `allowed` — array of booleans, same length as `tokens`
2. Run:
```sh
yarn deploy --network <network> --parameters ignition/parameters/<network>.json
```
The deployed Reputation/Multicall/P2PIX addresses are written to
`ignition/deployments/chain-<id>/deployed_addresses.json`.
```sh
yarn deploy1:mumbai
yarn deploy2:mumbai
```

## Context

sender of the transaction and its data. While these are generally available
via msg.sender and msg.data, they should not be accessed in such a direct

function recoverCalldata(bytes32 hash, bytes signature) internal view returns (address result)
```
_Recovers the signer's address from a message digest `hash`,
and the `signature`.
This function does NOT accept EIP-2098 short form signatures.
Use `recover(bytes32 hash, bytes32 r, bytes32 vs)` for EIP-2098
short form signatures instead._
### toEthSignedMessageHash
```solidity
function toEthSignedMessageHash(bytes32 hash) internal pure returns (bytes32 result)
```
_Returns an Ethereum Signed Message, created from a `hash`.
This produces a hash corresponding to the one signed with the
[`eth_sign`](https://eth.wiki/json-rpc/API#eth_sign)
JSON-RPC method as part of EIP-191._

```
_List of Locks._
### userRecord

### constructor

```
### deposit
```solidity
function deposit(string pixTarget, bytes32 allowlistRoot, contract ERC20 token, uint96 amount, bool valid) public
```
Creates a deposit order based on a seller's
offer of an amount of ERC20 tokens.
Seller needs to send his tokens to the P2PIX smart contract.
_Function sighash: 0x5e918943_
#### Parameters
| Name | Type | Description |
| ---- | ---- | ----------- |
| pixTarget | string | Pix key destination provided by the offer's seller. |
| allowlistRoot | bytes32 | Optional allow list merkleRoot update `bytes32` value. as the deposit identifier. |
| token | contract ERC20 | |
| amount | uint96 | |
| valid | bool | |
### setValidState
```solidity
function setValidState(contract ERC20 token, bool state) public
```
Enables seller to invalidate future
locks made to his/her token offering order.
This function does not affect any ongoing active locks.
_Function sighash: 0x6d82d9e0_
### lock
```solidity
function lock(address seller, contract ERC20 token, uint80 amount, bytes32[] merkleProof, uint256[] expiredLocks) public returns (uint256 lockID)
```
Public method designed to lock an remaining amount of
the deposit order of a seller.
Transaction forwarding must leave `merkleProof` empty;
otherwise, the trustedForwarder must be previously added
to a seller whitelist.
This method can be performed either by:
- An user allowed via the seller's allowlist;
- An user with enough userRecord to lock the wished amount;
There can only exist a lock per each `_amount` partitioned
from the total `remaining` value.
Locks can only be performed in valid orders.
_Function sighash: 0xdc43221c_
#### Parameters
| Name | Type | Description |
| ---- | ---- | ----------- |
| seller | address | |
| token | contract ERC20 | |
| amount | uint80 | The deposit's remaining amount wished to be locked. |
| merkleProof | bytes32[] | Provided as a pass if the `msg.sender` is in the seller's allowlist; Left empty otherwise; |
| expiredLocks | uint256[] | An array of identifiers to be provided so to unexpire locks using this transaction gas push. |
#### Return Values
| Name | Type | Description |
| ---- | ---- | ----------- |
| lockID | uint256 | The lock identifier. |
### release
```solidity
function release(uint256 lockID, bytes32 pixTimestamp, bytes signature) public
```
Lock release method that liquidate lock
orders and distributes relayer fees.
This method can be called by any public actor
as long the signature provided is valid.
`relayerPremium` gets splitted equaly
if relayer addresses differ.
If the `msg.sender` of this method and `l.relayerAddress` are the same,
`msg.sender` accrues both l.amount and l.relayerPremium as userRecord credit.
In case of they differing:
- `lock` caller gets accrued with `l.amount` as userRecord credit;
- `release` caller gets accrued with `l.relayerPremium` as userRecord credit;
_Function sighash: 0x11fc7f9a_
### unlockExpired
```solidity
function unlockExpired(uint256[] lockIDs) public
```
Unlocks expired locks.
Triggered in the callgraph by both `lock` and `withdraw` functions.
This method can also have any public actor as its `tx.origin`.
For each successfull unexpired lock recovered,
`userRecord[_castAddrToKey(l.relayerAddress)]` is decreased by half of its value.
_Function sighash: 0xb0983d39_
### withdraw
```solidity
function withdraw(contract ERC20 token, uint256 amount, uint256[] expiredLocks) public
```
Seller's expired deposit fund sweeper.
A seller may use this method to recover
tokens from expired deposits.

### setRoot
```solidity
function setRoot(address addr, bytes32 merkleroot) public

```
### getPixTarget
```solidity
