Runs a Cloudflare Worker that proxies and deduplicates EVM RPC requests to the Alchemy API. The worker is deployed to Cloudflare's edge infrastructure.
The intended use case is to reduce the number of requests to the Alchemy API by deduplicating identical requests. This is useful when multiple clients are querying the same data, such as when making requests through the EVM RPC Canister on the Internet Computer.
The worker will cache the response from Alchemy and return the cached response to all subsequent requests with the same parameters.
Set up a Cloudflare account and install the Wrangler CLI. Wrangler is used to develop, deploy, and configure your Worker via CLI.
Further documentation for Wrangler can be found here.
The worker is configured using the following environment variables:
ALCHEMY_API_KEY: The API key to use when making requests to Alchemy.
Give the worker a name by editing wrangler.toml:
name = "..."Configure Alchemy API key:
npx wrangler secret put ALCHEMY_API_KEYDeploy the worker to Cloudflare using:
pnpm i
pnpm run deployIn your IC project, to configure the EVM RPC Canister to use the proxy instead of the default services, see the following example:
let base_url = "https://<proxy-url-on-cludflare>.workers.dev";
// For ETH Sepolia
let rpc_services = RpcServices::Custom {
chainId: 11155111,
services: vec![RpcApi {
url: format!("{}/{}", base_url, "eth-sepolia"),
headers: None,
}],
},- Create a
.dev.varsfile in the root of the project. - Add the following content to the file:
ALCHEMY_API_KEY=<API_KEY>pnpm i
pnpm run dev- kristofer@kristoferlund.se
