# Registration Using Remix

This guide is based on the contract address and amount supplied. Take this guide as a reference and type in the exact numbers and address as told.

### MetaMask

* Networks

```json
KLAYTN : https://public-en-cypress.klaytn.net
```

* Add Network from the networks dropdown if needed

* Open Networks again and select the network you added

## [Remix IDE](https://remix.ethereum.org/)

Remix IDE - an online IDE to develop smart contracts.

* [Docs](https://remix-ide.readthedocs.io/en/latest/index.html)
* Download abi files

{% file src="/files/FaKvJ0AGhH1SYTbdR09h" %}
Layer 1 means original token platforms (ex. KSP's Layer 1 => KLAYTN)
{% endfile %}

{% file src="/files/wrR9MRxlL8XiVzE8d35c" %}
ft means Fungible Token (ERC-20, KIP-7)
{% endfile %}

* Load abi files into Remix IDE

* Select ft.abi

<div align="left"><figure><img src="/files/CJ2hYXfpPxZjy9M6Lp5U" alt=""><figcaption></figcaption></figure></div>

* Approve Token
  * Select Deploy & Run Transaction on left bar
  * Select Injected Web3 for Environment&#x20;
    * For Metamask
    * Check chainID (ex. KLAYTN : 8217)
  * Put your token address and Load Contract (ex. KSP :  0xc6a2ad8cc6e4a7e08fc37cc5954be07d499e7654)
  * Put spender and the amount to be bridged&#x20;
    * In this case KLAYTN Layer 1 contract : 0x9Abc3F6c11dBd83234D6E6b2c373Dfc1893F648D
    * If your original token is on a chain other than KLAYTN, please refer to the [Layer 1 contract addresses](broken://pages/7Xbz9zj23T8zpbmhKnd9)
  * Click transact button

* Send Transaction using Metamask

* Bridge Token
  * Load the Layer 1 contract referring to the Approve Token step
  * KLAYTN Layer 1 contract : 0x9Abc3F6c11dBd83234D6E6b2c373Dfc1893F648D
  * Get ChainId for toChain (Use MATIC for POLYGON due to predefined bridge rules)
  * Put chainId to check if toChain is a supported chain
  * Put chainId to check the bridge fee to toChain
    * If chainFee is zero, then value set 0
    * if not, you must put chainFee in VALUE. (ether = 10^18 wei)
  * Dropdown depositToken, fill params and click transact
    * token : your token address \
      (ex. KSP : 0xc6a2ad8cc6e4a7e08fc37cc5954be07d499e7654)
    * toAddr : address for receive bridged token
    * amount : 1 \
      (ex. 0.04 KSP = 40000000000000000, decimal = 18)\
      Basically, you are sending the minimum amount to register the token, 1/10^18 since the contract is based on the standard of decimal 18
  * Send Transaction referring to the Send Transaction using Metamask step
  * You can check the bridged token by searching for toAddr in toChain's explorer
