Take this guide as a reference and type in the exact numbers and address as told. ### MetaMask * Networks ```json KLAYTN : https://public-node-api.klaytnapi.com/v1/cypress ``` * 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/it2a0uWRVnd4e9C9aIds" %} Layer 1 means original token platforms (ex. KSP's Layer 1 => KLAYTN) {% endfile %} {% file src="/files/sNjbwWMnzxjHOF2Z4Q4D" %} ft means Fungible Token (ERC-20, KIP-7) {% endfile %} * Load abi files into Remix IDE

* Select ft.abi

* Approve Token * Select Deploy & Run Transaction on left bar * Select Injected Web3 for Environment * 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 * 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](/bridgedocs/token-registration-for-bridging/reference-layer-1-contracts.md) * Click transact button

* Send Transaction using Metamask ![choose edit](https://1278909119-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MjXzSdnsqu8hThNVH3A%2Fuploads%2FSPkK2tGzDN8LwJKr1yXt%2Fimage.png?alt=media\&token=7a5f4707-7e62-41c7-8460-b1a61f552228) ![edit gas fee](https://1278909119-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MjXzSdnsqu8hThNVH3A%2Fuploads%2F0Rw27mX2nSctGO0unbTL%2Fimage.png?alt=media\&token=9208d4a5-ed52-4f8e-9b76-2e7dda268f8e) ![make sure priority fee and fee to 750](https://1278909119-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MjXzSdnsqu8hThNVH3A%2Fuploads%2Fcsqu2VJkatg47CLBPXrU%2Fimage.png?alt=media\&token=d0dc6b52-ecbb-413f-b0d7-18a547239c22) * Bridge Token * Load the Layer 1 contract referring to the Approve Token step * KLAYTN Layer 1 contract : 0x9Abc3F6c11dBd83234D6E6b2c373Dfc1893F648D * Get ChainId for toChain (Use TON for TON 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 do not need to put chainFee in VALUE. (ether = 10^18 wei) * Dropdown depositToken, fill params and click transact * token : your token address \ (ex. KSP : 0xc6a2ad8cc6e4a7e08fc37cc5954be07d499e7654) * toAddr : \[Your TON based wallet address that want to receive your token]\ TON based wallet has different type as we generally use for KIP7. Please refer to the scripts' hashPart for switching your address to 32byte address\ * amount : 1 \ 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

If the chainFee shows any gas fee, put the same amount in the GAS FEE value
