If you would like to include any of the above assets on your Skale chain, please follow the instructions below. Approval is not required from the Europa DAO to bridge Europa Origin tokens to your Skale chain.

• 1: use private key with CHAIN_CONNECTOR_ROLE to connect skale chains using method connectSchain with input elated-tan-skat on token linker contract 0xD2aAA00800000000000000000000000000000000 : predeployed across all Skale chains. Please check block explorer for successful tx.
• 2: deploy skaleERC20 token with the same symbol as indicated above under the Origin Token Addresses, for thetoken name use the origin chain name aka Europa with the symbol ie: Europa USDP , and with the same decimals as indicated on Europa. After deployement, you should only refer to this token contract address as the target_token address.
• 3: assign newly deployed token contract address MINTER_ROLE and BURNER_ROLE to the erc20 token manager contract 0xD2aAA00500000000000000000000000000000000 : predeployed across all skale chains, however please double check your erc20 token manager contract address by visiting the token linker contract on your block explorer and use method viewTokenManagers with input 1. Here is an example on Europa: blockexplorer
• 4: use method addERC20TokenByOwner with input schain elated-tan-skat , Europa Wrapped-Origin token address, skaleERC20 deployed_contract_address on token manager contract. Please check block explorer for successful tx.

The final step is to transfer the Europa Wrapped-Origin token to your Skale chain

• rpc: https://mainnet.skalenodes.com/v1/elated-tan-skat connect to the Europa chain
• use any private key holding Europa assets.
• 1: Transfer to target : erc20 token manager contract 0xD2aAA00500000000000000000000000000000000with method transferToSchainERC20 and input your Skale chain_name, Wrapped_Origin_Token_Address, and the amount. The token_address must match the Wrapped_Origin_Token_Address on Europa.

• rpc: https://mainnet.skalenodes.com/v1/your-skale-chain-name connect to the Dapp chain
• use any private key holding Dapp Chain assets.
• 1: Transfer to origin : : erc20 token manager contract 0xD2aAA00500000000000000000000000000000000with method transferToSchainERC20 and input elated-tan-skat, Wrapped_Origin_token_address, and the amount. The token_address must match the Wrapped_Origin_Token_Address on Europa.
