# ICON

## Code

* `minter.py`
* Code can be found in [HERE](https://github.com/orbit-chain/bridge-contract)

## Events

### Swap

```bash
@eventlog
def Swap(self, hubContract: bytes, fromChain: str, toChain: str, fromAddr: bytes, toAddr: bytes, tokenAddress: bytes, bytes32s: bytes, uints: bytes, data: bytes):
        pass
```

This event occurs when a bridge operator performs bridging with ICON Minter through the Orbit Bridge System.

* `bytes hubContract` : Orbit Hub Contract Address
* `str fromChain` : Chain Symbol requesting bridging
* `str toChain` : Chain Symbol to execute bridging
* `bytes fromAddr` : Address of the chain requesting bridging
* `bytes toAddr` : Address of chain to execute bridging
* `bytes tokenAddress` : Token Address minted by bridging execution
* `bytes bytes32s` : Bytes32 data array used in the bridging consensus process
* `bytes uints` : Uint data array used in the bridging consensus process
* `bytes data` : Execution data for Bridge Receiver

### SwapNFT

```bash
@eventlog
def SwapNFT(self, hubContract: bytes, fromChain: str, toChain: str, fromAddr: bytes, toAddr: bytes, tokenAddress: bytes, bytes32s: bytes, uints: bytes, data: bytes):
        pass
```

This event occurs when a bridge operator performs bridging with ICON Minter through the Orbit Bridge System.

* `bytes hubContract` : Orbit Hub Contract Address
* `str fromChain` : Chain Symbol requesting bridging
* `str toChain` : Chain Symbol to execute bridging
* `bytes fromAddr` : Address of the chain requesting bridging
* `bytes toAddr` : Address of chain to execute bridging
* `bytes tokenAddress` : Token Address minted by bridging execution
* `bytes bytes32s` : Bytes32 data array used in the bridging consensus process
* `bytes uints` : Uint data array used in the bridging consensus process
* `bytes data` : Execution data for Bridge Receiver

### SwapRequest

```bash
@eventlog
def SwapRequest(self, fromChain: str, toChain: str, fromAddr: bytes, toAddr: bytes, token: bytes, tokenAddress: bytes, decimal: int, amount: int, depositId: int, data: bytes):
    pass
```

Event occurs when a user who uses the Orbit Bridge System requests bridging to ICON Minter

* `str fromChain` : Chain Symbol requesting bridging
* `str toChain` : Chain Symbol to execute bridging
* `bytes fromAddr` : Address of the chain requesting bridging
* `bytes toAddr` : Address of chain to execute bridging
* `bytes token` : Token Information to be executed bridging
* `bytes tokenAddress` : Token Address  requesting bridging
* `int decimal` : Token Decimal requesting bridging
* `int amount` : Token Amount requesting bridging
* `int depositId` : Unique Identifier of bridging request
* `bytes data` : Execution data for Bridge Receiver

## Interface

```bash
class MinterInterface(InterfaceScore):
    @interface
    def getTokenAddress(self, token: bytes) -> Address:
        pass

    @interface
    def getChainId(self, chain: str) -> bytes:
        pass

    @interface
    def swap(self, hubContract: bytes, fromChain: str, fromAddr: bytes, toAddr: bytes, token: bytes, bytes32s: bytes, uints: bytes, sigs: str, data: bytes = None):
        pass
    
    @interface
    def swapNFT(self, hubContract: bytes, fromChain: str, fromAddr: bytes, toAddr: bytes, token: bytes, bytes32s: bytes, uints: bytes, sigs: str, data: bytes = None):
        pass
    
    @interface
    @payable
    def requestSwap(self, tokenAddress: Address, toChain: str, toAddr: bytes, amount: int, data: bytes = None):
        pass

    @interface
    @payable
    def def requestSwapNFT(self, nftAddress: Address, toChain: str, toAddr: bytes, tokenId: int, data: bytes = None):
        pass
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://bridge-docs.orbitchain.io/contract/minter/icon.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
