simple test contract

SimpleStorageV2 is a truffle project that contains simple test ethereum smart-contract for polyjuice-provider used on Godwoken-Polyjuice chain.

Compile contract

  yarn compile

Depoly contract

deploy to godwoken-polyjuice chain using truffle and @polyjuice-provider/truffle.

first, set a .env file:

cat > ./.env <<EOF
WEB3_JSON_RPC=<godwoken wb3 rpc>
ROLLUP_TYPE_HASH=<godwoken rollup type hash>
ETH_ACCOUNT_LOCK_CODE_HASH=<eth account lock code hash>
PRIVATE_KEY=<your eth test private key, do not use in production>
EOF

then run

  yarn deploy

Known issue

one thing to notice is that, due to an known fact about decimal difference between CKB token and ETH token, you should set gasPrice: "0" in truffle-config.js for your truffle project, otherwise you will encounter balance not enoug issue during dryRun migration. set gasPrice: 0 won't work, the 0 must be a string type`
