EOSIO Side Setup


Install Zeus if not installed, zeus is used to unbox or install all the necessary dependencies to compile and deploy the necessary contracts.

Ensure you're using node version 16, IPFS can be picky with other versions

Unbox atomictokenpeg box

mkdir atomictokenpeg
cd atomictokenpeg
zeus box create
zeus unbox atomictokenpeg

Before compiling atomictokenpeg.cpp you must update the atomic assets constant here

const name NFT_ACCOUNT = "bridgeassets"_n;

Compile contracts

zeus compile

Create 3 Kylin and 3 Mumbai Testnet accounts using these guides:

Kylin Accounts:

  • Kylin token contract account (token being bridged eosio.token.cpp)

  • Kylin bridge contract account (atomictokenpeg.cpp)

  • Kylin test Account no contract

Mumbai Testnet Accounts

  • ERC721 Contract (atomicnft.sol) with extensions

    • ERC721Enumerable

    • ERC721Burnable

    • ERC721Pausable

  • Mumbai bridge contract Account (atomictokenpeg.sol)

  • Mumbai test Account no contract

export KYLIN_BRIDGE_ACCOUNT=maticnftbrdg
export KYLIN_TOKEN_ACCOUNT=bridgeassets
export KYLIN_TEST_ACCOUNT=natdeveloper
export KYLIN_ENDPOINT=https://kylin.eosn.io

Import our keys into zeus to deploy contracts to Kylin, or can use cleos as well

zeus key import $KYLIN_BRIDGE_ACCOUNT --network kylin --active-private-key 5JB... --owner-private-key 5JB...

Create contract deployment files to migrate contracts to Kylin, located in ./zeus_boxes/contract-migrations-extensions/models/contract-deployments/

zeus create contract-deployment atomictokenpeg $KYLIN_BRIDGE_ACCOUNT kylin

Migrate contracts to Kylin/Jungle

zeus migrate atomictokenpeg --network=kylin --creator $KYLIN_BRIDGE_ACCOUNT --no-reset --no-compile-all --creator-key=""

If you use cleos to set the contract, be sure to set the eosio.code permission level, see here

Stake for services

Now that we've prepared that part let's move onto staking DAPP for services. First stop is the faucet for some DAPP tokens here. Use the account that has the atomictokenpeg contract set to it.

Stake to required services vRAM, LiquidHarmony Oracles, LiquidScheduler, LiquidLink

Using the DSP Portal we can see these packages, stake 10 DAPP to each (Amount to Stake):

Below we'll select each package then stake for it.

export PROVIDER=uuddlrlrbass
export PACKAGE=ipfs2
export SERVICE=ipfsservice1
export QUANTITY="10.0000 DAPP"
cleos -u $KYLIN_ENDPOINT push action dappservices selectpkg "[\"$KYLIN_BRIDGE_ACCOUNT\",\"$PROVIDER\",\"$SERVICE\",\"$PACKAGE\"]" -p $KYLIN_BRIDGE_ACCOUNT@active
cleos -u $KYLIN_ENDPOINT push action dappservices stake "[\"$KYLIN_BRIDGE_ACCOUNT\",\"$PROVIDER\",\"$SERVICE\",\"$QUANTITY\"]" -p $KYLIN_BRIDGE_ACCOUNT@active

Use the command line login option, top right, this will auto-create the cleos commands for you!

Now let's head over to the EVM side.
