@@ -12,7 +12,7 @@ Deploying the NEAR contract has three steps:
 1. Create a NEAR key with `near generate-key`
 2. Fetch NEAR tokens from an available faucet, at last deploy around 100~ NEAR were needed.
 3. See the example deploy script in `scripts/deploy.sh` to deploy the contract. You can find a codehash by:
-   - `sha256sum pyth.wasm` after building the contract.
+   - `sha256sum pyth_near.wasm` after building the contract.
    - `list(bytes.fromhex(hash))` in Python to get a byte array.
    - Replace the `codehash` field in deploy.sh for the initial codehash.
    - Replace the sources with the keys expected by the network you're deploying on (testnet vs mainnet).
