{% endfile %}
* Load abi files into Remix IDE

* 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](https://orbit-1.gitbook.io/bridgedocs/token-registration-for-bridging/reference-layer-1-contracts)
