Verify a Merkle Lockup contract in 4 easy steps

[smol-ninja]

Tip

Since Etherscan automatically verifies the contracts based on the matching source code criterion, this verification is only required once per chain.

We will use the following MerkleLL contract, deployed on Polygon, as an example 0x8BBe....7776.

Step 1

👉 Click the contract creation tx from the "More Info" section.

Step 2

🧠 Click to show more → Memorize the function name from the default view.

📝 View input as original → Copy the input data.

Step 3

👉 Go to SablierMerkleLockupDecoder contract → Enter the input data to the relevant function → Copy the output (this is the CONSTUCTOR ARG for merkle lockup contract to verify).

Step 4

Go to v2-periphery repo (you have to clone it and run bun i first if you don't have it already).

🐣 Load the variables into the shell:

export ETHERSCAN_API_KEY=
export ETHERSCAN_URL=
export CONSTUCTOR_ARG=
export CONTRACT_TO_VERIFY=

👨🏻‍💻 Run the verification command:

FOUNDRY_PROFILE=optimized \
forge verify-contract --etherscan-api-key $ETHERSCAN_API_KEY --verifier-url $ETHERSCAN_URL \
--constructor-args $CONSTUCTOR_ARG $CONTRACT_TO_VERIFY \
src/SablierV2MerkleLL.sol:SablierV2MerkleLL --watch

You must change src/SablierV2MerkleLL.sol:SablierV2MerkleLL to src/SablierV2MerkleLT.sol:SablierV2MerkleLT if you wish to verify a MerkleLT contract.

That's all for today. Thank you for reading 💚
