Testnet Deployment

  1. Run local geth networks
./scripts/start-geth.sh gethBaseChain # localhost:7545
./scripts/start-geth.sh gethSatChain1 # localhost:8545
./scripts/start-geth.sh gethSatChain2 # localhost:9545
  1. Setup deployer key
# create keyfile
export KEYFILE=[Path to key file]
export PASSPHRASE=
  1. Deploy AMPL contracts
# deploy base-chain ampleforth oracle, policy and token contracts  
yarn hardhat --network gethBaseChain testnet:deploy:ampleforth \
  --keyfile $KEYFILE --passphrase $PASSPHRASE \

# deploy cross-chain ample contracts on satellite-chain-1
yarn hardhat \
  --network gethSatChain1 \
  deploy:ampleforth_xc \
  --keyfile $KEYFILE --passphrase $PASSPHRASE \
  --token-name "sat1-chainBridge-Ample" \
  --token-symbol "sat1CBAmple" \
  --base-chain-network gethBaseChain

# deploy cross-chain ample contracts on satellite-chain-2
yarn hardhat \
  --network gethSatChain2 \
  deploy:ampleforth_xc \
  --keyfile $KEYFILE --passphrase $PASSPHRASE \
  --token-name "sat2-chainBridge-Ample" \
  --token-symbol "sat2CBAmple" \
  --base-chain-network gethBaseChain
  1. Deploy Chain bridge contracts and connections
# deploy contracts on base chain
yarn hardhat --network gethBaseChain deploy:chain_bridge:base_chain \
  --keyfile $KEYFILE --passphrase $PASSPHRASE \
  --chain-id 251 \
  --relayers "[\"0x70c76fa963f2d6d06bb9c640ab843c96bd48c590\",\"0xce101c1b7029d06e332f920ae117dd65d8eba955\"]" \
  --relayer-threshold 1 \
  --fee 0 \
  --expiry 1000

# deploy contracts on satellite-chain-1
yarn hardhat --network gethSatChain1 deploy:chain_bridge:satellite_chain \
  --keyfile $KEYFILE --passphrase $PASSPHRASE \
  --chain-id 252 \
  --relayers "[\"0x70c76fa963f2d6d06bb9c640ab843c96bd48c590\",\"0xce101c1b7029d06e332f920ae117dd65d8eba955\"]" \
  --relayer-threshold 1 \
  --fee 0 \
  --expiry 1000

# deploy contracts on satellite-chain-2
yarn hardhat --network gethSatChain2 deploy:chain_bridge:satellite_chain \
  --keyfile $KEYFILE --passphrase $PASSPHRASE \
  --chain-id 253 \
  --relayers "[\"0x70c76fa963f2d6d06bb9c640ab843c96bd48c590\",\"0xce101c1b7029d06e332f920ae117dd65d8eba955\"]" \
  --relayer-threshold 1 \
  --fee 0 \
  --expiry 1000
  1. Generate the chain-bridge config file required to run relayers
# the following command generates the chain-bridge config-1.json/config-2.json
yarn hardhat config:chain_bridge \
  --networks "[\"gethBaseChain\",\"gethSatChain1\",\"gethSatChain2\"]" \
  --relayer-address "0x70c76fa963f2d6d06bb9c640ab843c96bd48c590"

yarn hardhat config:chain_bridge \
  --networks "[\"gethBaseChain\",\"gethSatChain1\",\"gethSatChain2\"]" \
  --relayer-address "0xce101c1b7029d06e332f920ae117dd65d8eba955"

chainbridge --config config-1.json --verbosity trace --latest
chainbridge --config config-2.json --verbosity trace --latest

NOTE: Replace http urls to ws, as chain-bridge expects web socket connections.

  1. Inspect state

# prints ampl state
yarn hardhat info:ampl \
  --networks "[\"gethBaseChain\",\"gethSatChain1\",\"gethSatChain2\"]"

# prints ampl balances across chains
yarn hardhat info:ampl:balance \
  --networks "[\"gethBaseChain\",\"gethSatChain1\",\"gethSatChain2\"]" \
  --wallet "0x3b2b9EfdaE5291F3Bb9C7e6508C7e67534511585"

# prints bridge state
yarn hardhat info:chain_bridge \
  --networks "[\"gethBaseChain\",\"gethSatChain1\",\"gethSatChain2\"]"
  1. Cross-chain transactions
# trigger rebase on main-chain
yarn hardhat --network gethBaseChain testnet:rebase:base_chain \
  --keyfile $KEYFILE --passphrase $PASSPHRASE \
  --rebase-perc 10

# report rebase from base-chain to satellite-chains
yarn hardhat --network gethBaseChain report_rebase:base_chain \
  --satellite-chain-networks "[\"gethSatChain1\",\"gethSatChain2\"]" \
  --keyfile $KEYFILE --passphrase $PASSPHRASE

# wait for relayer to report rebase execute rebase on satellite chains
yarn hardhat rebase:satellite_chain \
  --networks "[\"gethSatChain1\",\"gethSatChain2\"]" \
  --keyfile $KEYFILE --passphrase $PASSPHRASE


# cross-chain transfer from base to satellite
yarn hardhat --network gethBaseChain xc_transfer \
  --target-chain-network gethSatChain1 \
  --keyfile $KEYFILE --passphrase $PASSPHRASE \
  --recipient-address "0x3b2b9EfdaE5291F3Bb9C7e6508C7e67534511585" \
  --amount 100

# cross-chain transfer from satellite to satellite
yarn hardhat --network gethSatChain1 xc_transfer \
  --target-chain-network gethSatChain2 \
  --keyfile $KEYFILE --passphrase $PASSPHRASE \
  --recipient-address "0x3b2b9EfdaE5291F3Bb9C7e6508C7e67534511585" \
  --amount 100

# cross-chain transfer from satellite to base
yarn hardhat --network gethSatChain2 xc_transfer \
  --target-chain-network gethBaseChain \
  --keyfile $KEYFILE --passphrase $PASSPHRASE \
