scroll-gateway

@ensdomains/scroll-gateway

An instantiation of evm-gateway that targets Scroll - that is, it implements a CCIP-Read gateway that generates proofs of contract state on Scroll.

For a detailed readme and usage instructions, see the monorepo readme.

To get started, you need to have an RPC URL for both Ethereum Mainnet and Scroll. You also need to provide an L2_ROLLUP address which is the Rollup contract deployed on Mainnet or the Nitro Node.

How to use scroll-gateway locally via cloudflare dev env (aka wrangler)

npm install -g bun
cd scroll-gateway
bun install
touch .dev.vars
## set L2_PROVIDER_URL and SEARCH_URL(the default for sepolia is https://sepolia-rpc.scroll.io)
yarn dev

How to deploy scroll-gateway to cloudflare

cd scroll-gateway
npm install -g wrangler
wrngler login

wrangler secret put L2_PROVIDER_URL
yarn deploy

How to test

There is currently no local test node. You need to deploy to public testnet and run the test.

1. deploy l2 contractL2_ETHERSCAN_API_KEY=$L2_ETHERSCAN_API_KEY DEPLOYER_PRIVATE_KEY=$DEPLOYER_PRIVATE_KEY L2_PROVIDER_URL=$L2_PROVIDER_URL npx hardhat deploy --network scrollSepolia
2. deploy l1 contract. Modify GATEWAY_URLS on 00_scroll_verifier.ts to point to localhost and run L1_ETHERSCAN_API_KEY=$L1_ETHERSCAN_API_KEY DEPLOYER_PRIVATE_KEY=$DEPLOYER_PRIVATE_KEY L1_PROVIDER_URL=$L1_PROVIDER_URL ROLLUP_ADDRESS=$ROLLUP_ADDRESS npx hardhat deploy --network sepolia
3. startup gateway server

cd ../evm-gateway
// Add .dev.vars and add L1_PROVIDER_URL, L2_PROVIDER_URL, and L2_ROLLUP
yarn dev

4. run the test DEPLOYER_PRIVATE_KEY=$DEPLOYER_PRIVATE_KEY L1_PROVIDER_URL=$L1_PROVIDER_URL ROLLUP_ADDRESS=$ROLLUP_ADDRESS yarn test --network sepolia
