Deploy

EVM

Movelfow Contract

  • Deploy to bsc testnet:
    • npx hardhat --network bsc-testnet deploy --tags MoveflowCrosschain

MFL Token

  • Deploy to bsc testnet:
    • npx hardhat --network bsc-testnet deploy --tags MFLToken
  • Publish to bscscan:
    • npx hardhat verify --network bsc-testnet <MFL_CONTRACT_ADDR>
  • Mint MFL:

Aptos

  • Deploy to testnet:
    • Set layerzeroDeployedAddress in tests/moveflow.deploy.test.ts according to the env
    • cd sdk; npx jest ./tests/moveflow.deploy.test.ts, what the script should have done:
      • Deploy
      • Register UA
      • Register Aptos coin

MFL Token

cd apps/test-token
export APT_ACC=<YOUR ACCOUNT ADDRESS>
aptos move publish \
    --named-addresses mycoin=${APT_ACC}
aptos move run \
    --function-id 0x1::managed_coin::initialize \
    --args string:"MFL" string:"MFL" u8:8 bool:true \
    --type-args ${APT_ACC}::Coins::MFL \
    --assume-yes
aptos move run \
    --function-id 0x1::managed_coin::register \
    --type-args ${APT_ACC}::Coins::MFL \
    --assume-yes

CrossChain Init

EVM

  • Init
    • Set the following variables in tasks/setTrustedRemote.Aptos.js according to deployment above
      • remoteChainId
      • remoteAddress
      • ENDPOINT_HTTP
      • remoteMflAddress
    • npx hardhat --network bsc-testnet setTrustedRemote.Aptos, what the script should have done:
      • Mint MFL
      • Register MFL
      • Deposit MFL to cx chain pool
      • set trusted remote

Aptos

  • Init
    • Set the following variables in sdk/tests/moveflow.setRemote.test.ts according to deployment above and env
      • layerzeroDeployedAddress
      • mflOwnerAddress
      • rmtEvmContractAddr
      • rmtMflTokenAddress
      • rmtEvmReceiverAddr
      • remoteChainId
    • MFL Token owner transfers at least 0.1 MFL to Contract Owner.
    • Ensure the deployer's apt balance is greater than 3 apt.
    • cd sdk; npx jest ./tests/moveflow.setRemote.test.ts, what the script should have done：
      • Mint MFL
      • Register MFL on Moveflow contract
      • set_coin_map
      • setRemote
      • Create a stream whose receiver is an EVM user.

CrossChain Tx

EVM

  • Withdraw from aptos chain
    • Set the following variables in tasks/withdrawFrom.Aptos.js according to deployment above and env
      • streamId
      • remoteChainId
    • npx hardhat --network bsc-testnet withdrawFrom.Aptos

Test Helper

Aptos

  • Test crosschain withdraw
    • set the following in npx jest ./tests/moveflow.withdraw.test.ts
      • layerzeroDeployedAddress
      • mflOwnerAddress
      • rmtEvmContractAddr
      • streamId
      • remoteChainId

FAQ

Stuck Cx Chain Tx

  • Q: How do you recover the funds in a blocked tx / retry with a new nonce
    • Is this for V1? A blocked message just means that the previous nonce is a storedPayload. Once the StoredPayload has been cleared your tx will automatically clear and execute. You can retry a storedPayload via LayerZero Scan
