Deploying ERC721Mock (test only)

pnpm hardhat deploy-ERC721-mock --network 11155111 --token-name CryptoRastas --token-symbol RASTAS
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 11155111 --proxy-token 0xEa1bE678525726C050aE363D6561110567c6A005

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 80001 --name CryptoRastas --symbol RASTAS

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 11155111 --core-contract-address 0x08d6474eb92E8c4Df03E4223e0ec8d50f743c75f --destination-chain-id 80001 --destination-core-contract-address 0x357F0dc00AdE231db59aE38aCd8A0E73ed0125Ff

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

pnpm hardhat set-trusted-remote-address --network 80001 --core-contract-address 0x357F0dc00AdE231db59aE38aCd8A0E73ed0125Ff --destination-chain-id 11155111 --destination-core-contract-address 0x08d6474eb92E8c4Df03E4223e0ec8d50f743c75f

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 11155111 --core-contract-address 0x08d6474eb92E8c4Df03E4223e0ec8d50f743c75f --destination-chain-id 80001

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

pnpm hardhat set-min-destination-gas --network 80001 --core-contract-address 0x357F0dc00AdE231db59aE38aCd8A0E73ed0125Ff --destination-chain-id 11155111

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 11155111 --core-contract-address 0x08d6474eb92E8c4Df03E4223e0ec8d50f743c75f --destination-chain-id 80001 --token-address 0xEa1bE678525726C050aE363D6561110567c6A005 --token-id 1

optionally you can transfer back to initial chain

pnpm hardhat transfer-ERC721-to-destination-chain --network 80001 --core-contract-address 0x357F0dc00AdE231db59aE38aCd8A0E73ed0125Ff --destination-chain-id 11155111 --token-address 0x357F0dc00AdE231db59aE38aCd8A0E73ed0125Ff --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]
