Deploying ERC721Mock (test only)

pnpm hardhat deploy-ERC721-mock --network 11155111 --token-name CryptoRastas222 --token-symbol RASTAS222

Argument	Description	Default
--token-name	Token name	CryptoRastas
--token-symbol	Token symbol	RASTAS
--account-index	Account index to deploy from	0

Step 1 - deploying contracts

Deploy ProxyONFT721 on source chain:

Argument ****	Description	Default
--proxy-token	Proxy token address	[Address]
--min-gas-to-transfer	Min gas required to perform actions on chain	check
--lz-endpoint	L2 endpoint	check
--account-index	Account index to deploy from	0

pnpm hardhat deploy-proxy-ONFT721 --network 1 --proxy-token 0x07cd221b2fe54094277a2f4e1c1bc6df14e63678

and deploy ONFT721 on destination chain:

Argument	Description	Default
--name	Token name	CryptoRastas
--symbol	Token symbol	RASTAS
--account-index	Account index to deploy from	0
--min-gas-to-transfer	Min gas required to perform actions on chain	check
--lz-endpoint	L2 endpoint	check

pnpm hardhat deploy-ONFT721 --network 137 --name Cryptorastas --symbol RASTA

Step 2 - Setting up the bridge

Setting trusted remote address

Set destination chain as trusted remote address on source chain:

Argument	Description	Default
--account-index	Account index to deploy from	0
--core-contract-address	Core Contract address	[Address]
--destination-chain-id	Destination chain id	[ChainId]
--destination-core-contract-address	ONFT721 from destination chain	[Address]

pnpm hardhat set-trusted-remote-address --network 1 --core-contract-address 0xfD691DCf0Cd713986F9218F3dc7aEb5f2b9e7480 --destination-chain-id 137 --destination-core-contract-address 0xfD691DCf0Cd713986F9218F3dc7aEb5f2b9e7480

repeat the process on the destination chain, to trust the source chain:

pnpm hardhat set-trusted-remote-address --network 137 --core-contract-address 0xfD691DCf0Cd713986F9218F3dc7aEb5f2b9e7480 --destination-chain-id 1 --destination-core-contract-address 0xfD691DCf0Cd713986F9218F3dc7aEb5f2b9e7480

Setting min gas required

Set destination chain min gas required to perform actions on chain:

Argument	Description	Default
--account-index	Account index to deploy from	0
--core-contract-address	Core Contract address	[Address]
--destination-chain-id	Destination chain id	[ChainId]
--min-destination-gas	Min gas required to perform actions on chain	check
--packet-type	Packet type	1 (send and call)

pnpm hardhat set-min-destination-gas --network 1 --core-contract-address 0xfD691DCf0Cd713986F9218F3dc7aEb5f2b9e7480 --destination-chain-id 137

repeat the process on the destination chain, to set min gas required to perform actions on chain:

pnpm hardhat set-min-destination-gas --network 137 --core-contract-address 0xfD691DCf0Cd713986F9218F3dc7aEb5f2b9e7480 --destination-chain-id 1

Step 3 - Transfer ERC721

Transfer ERC721 to destination chain

Argument	Description	Default
--account-index	Account index to deploy from	0
--token-id	Token id	[TokenId]
--token-address	Token address	[Address]
--core-contract-address	Core Contract address	[Address]
--destination-chain-id	Destination chain id	[ChainId]
--packet-type	Packet type	1 (send and call)

pnpm hardhat transfer-ERC721-to-destination-chain --network 1 --core-contract-address 0xfD691DCf0Cd713986F9218F3dc7aEb5f2b9e7480 --destination-chain-id 137 --token-address 0x07cd221b2fe54094277a2f4e1c1bc6df14e63678 --token-id 1

optionally you can transfer back to initial chain

pnpm hardhat transfer-ERC721-to-destination-chain --network 137 --core-contract-address 0xfD691DCf0Cd713986F9218F3dc7aEb5f2b9e7480 --destination-chain-id 1 --token-address 0xfD691DCf0Cd713986F9218F3dc7aEb5f2b9e7480 --token-id 1

Step 4 - Verifing contracts

Run this command to verify contracts on selected network

pnpm verify --network [networkid] --contract contracts/[ContractName].sol:[Contract] [contractAddress] [arguments]
