# BondIntent

#### Overview

The `BondIntent` allows users to express the desire to borrow liquidity for the purpose of inventory free solving. The `BondIntent` is an ERC721 token that the filler of the BondIntent mints when the bond intent is filled.

#### Message Format

Messages largely match what is in the intentpool specification. The `BondInfo` has the following fields:

```solidity
struct BondInfo {
    address solver;
    uint256 nonce;
    bytes32 orderHash; // hash of the bond order
    uint256 srcFee; // fee taken on the src chain
    Item input; // input of the order
    Item output; // output of the order
    address lpToken; // the token the filler of the BondIntent needs to provide
    uint256 lpAmount; // the amount the filler of the BondIntent needs to provide
    uint256 deadline;  // deadline for the intent issuer to successfully use the borrowed liqudity
}
```

* `solver` , the address of the original bond issuer
* `nonce` , a nonce provided for preventing replay
* `orderHash` is the hash of the bond order.
* `srcFee` fee taken by the bond purchaser on the origin chain
* `lpToken` the token the filler will repay to the bond purchaser needs to provide
* `lpAmount` the amount of token the bond purchaser to provide.
* `deadline` is the deadline for the intent issuer to successfully use the borrowed liquidity.

```solidity
struct Item {
    address token; // ERC20 token
    uint256 amountStart;
    uint256 amountEnd;
    uint32 chainId;
}
```

#### Fees

There are two fees, those paid on the origin chain and fees paid on the destination chain. The fees from the origin chain are implemented as a revenue-sharing measure between filler and liquidity provider, and are taken from the funds from the initiating swapper. The fees on the destination chain are provided in a separate token to the bond purchaser.
