Bridge KIP-7 (fungible token, original token on KLAYTN) to another chain (Ethereum, Polygon, etc...)
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
Add Network from the networks dropdown if needed
Open Networks again and select the network you added
Remix IDE - an online IDE to develop smart contracts.
Download abi files
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
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
