Deployment Guide

Mainnet deployment

Setup your personalized local environment:

export NETWORK_NAME=mainnet
export GAS_PRICE_GWEI=13
 export PK=<your private key goes here>
 export MY_ETHERSCAN_API_KEY=<your private Etherscan API key goes here>

Note the space before the private key exports ensures that the line will not be recorded in your bash history.

# clear build directory
rm -r build
npx truffle compile
npm run networks-inject
npx truffle migrate --reset --network $NETWORK_NAME
npm run networks-extract
npx truffle run verify BatchExchange --network $NETWORK_NAME

If last command (verifier) doesn't work, do it manually using the flattener:

npx truffle-flattener contracts/BatchExchange.sol > flattend.txt

Commit new network.json file and then bump npm package:

npm version patch -m “New deployment”
npm publish

Adding tokens to exchange

 npx truffle exec scripts/stablex/add_token_list.js --network $NETWORK_NAME

Depositing Tokens and Placing Orders:

# Deposit OWL:
npx truffle exec scripts/stablex/deposit.js --accountId=0 --tokenId=0 --amount=30 --network $NETWORK_NAME

Obtaining Listed Token IDs

npx truffle exec scripts/stablex/invokeViewFunction.js ‘tokenAddressToIdMap’ <Token Address> --network $NETWORK_NAME
export TOKEN_ID=<Result of Previous Command>

Depositing

npx truffle exec scripts/stablex/deposit.js --accountId=0 --tokenId=$TOKEN_ID --amount=98 --network $NETWORK_NAME

Placing Orders

OWL for DAI order:

npx truffle exec scripts/stablex/place_order.js --accountId=0 --buyToken=$TOKEN_ID_DAI --sellToken=0 --minBuy=1000 --maxSell=1000 --validFor=2000 --network $NETWORK_NAME

Market maker order TUSD vs DAI:

npx truffle exec scripts/stablex/place_order.js --accountId=0 --buyToken=$TOKEN_ID_DAI --sellToken=$TOKEN_ID_TUSD --minBuy=1000 --maxSell=998 --validFor=200 --network $NETWORK_NAME

Market maker order DAI vs TUSD

npx truffle exec scripts/stablex/place_order.js --accountId=0 --buyToken=$TOKEN_ID_TUSD --sellToken=$TOKEN_ID_DAI --minBuy=1000 --maxSell=998 --validFor=200 --network $NETWORK_NAME

WARNING!

Some tokens, such as USDC, have only 6 decimals while most have 18. This must be taken into consideration when depositing and placing orders, especially via these scripts since the convert values by multiplying 10^18.

Observe, for example, the order placed between DAI and TUSD above in comparison with the following:

npx truffle exec scripts/stablex/place_order.js --accountId=0 --buyToken=3 --sellToken=4 --minBuy=102000000000000 --maxSell=100 --validFor=2000 --network $NETWORK_NAME

npx truffle exec scripts/stablex/place_order.js --accountId=0 --buyToken=4 --sellToken=3 --minBuy=102 --maxSell=100000000000000 --validFor=2000 --network $NETWORK_NAME

OWL liquidity

Use the script ensure_owl_liquidity for automatic OWL liquidity provision for all tokens:

 npx truffle exec scripts/stablex/ensure_owl_liquidity.js --network $NETWORK_NAME
