+# Data Edge
+
+A DataEdge contract is used to store arbitrary data on-chain on any EVM compatible blockchain. A subgraph can then read all the calldata sent to a particular contract, decode it and update the subgraph state accordingly.
+
+The DataEdge accepts any function call by using a fallback function that will not revert. It is up to the implementor to define the calldata format as well as how to decode it.
+
+### Additional Considerations
+
+- Fallback is not payable to avoid anyone sending ETH by mistake as the main purpose is to store calldata.
+
+# Deploying
+
+Setup a `.env` file with the keys you want to use for deployments. You can use `.env.sample` as a guide.
+Deploy a `DataEdge` contract by running `yarn deploy -- --network <network-name>`
