evm-deployment

Overview

End-to-end deployment workflow for Sablier EVM contracts. Supports Comptroller, Flow, Lockup, and Airdrops with
protocol-specific adaptations.

Prerequisites

Version Check

Before proceeding, verify Foundry version:

forge -V

Stop if version is below 1.3.6.

Protocol Detection

Detect the current EVM protocol from package.json:

Package Name	Protocol	SDK Path
@sablier/evm-utils	Comptroller	../sdk/deployments/comptroller
@sablier/flow	Flow	../sdk/deployments/flow
@sablier/lockup	Lockup	../sdk/deployments/lockup
@sablier/airdrops	Airdrops	../sdk/deployments/airdrops

Extract version from package.json → "version": "x.y.z" → SDK version is v<x.y>

Workflow

Execute steps in order, tracking state between each:

Step 1: Deploy Contracts

Reference: ./references/deploy.md | Examples: ./references/examples.md

Deploy protocol contracts using Foundry. Handles:

• RPC configuration
• Deterministic (CREATE2) vs non-deterministic (CREATE) deployment
• Contract verification on block explorer

Step 2: Update SDK (optional)

Reference: ./references/copy-to-sdk.md

Copy broadcast artifacts to SDK repository:

• Broadcast JSON file
• Update README.md with deployment info
• Update deployments.ts with contract addresses

Step 3: Create Test Data (optional)

Reference: ./references/deploy-streams.md

For Flow and Lockup protocols only. Creates sample streams for testing:

• Mint or verify ERC20 token balance
• Run Init.s.sol script to create test streams

State Tracking

Track and carry forward between steps:

State	Source
Protocol name	Detected from package.json
Chain ID	From deployment or user input
Chain name	Lowercase (e.g., ethereum, arbitrum)
Deployment type	deterministic or non-deterministic
Contract addresses	From broadcast JSON returns field
Block number	From deployment receipt (hex → decimal)
SDK version	From package.json version

Protocol-Specific Scripts

Protocol	Deterministic Script	Non-deterministic Script
Comptroller	DeployDeterministicComptrollerProxy.s.sol	DeployComptrollerProxy.s.sol
Flow	DeployDeterministicProtocol.s.sol	DeployProtocol.s.sol
Lockup	DeployDeterministicProtocol.s.sol	DeployProtocol.s.sol
Airdrops	DeployDeterministicFactories.s.sol	DeployFactories.s.sol

Output Summary

After completion, provide:

• Protocol deployed
• Chain and deployment type
• Contract addresses (factories + campaigns if applicable)
• Verification status
• SDK files updated (if applicable)
• Test data created (if applicable)

Airdrops Campaign Contracts

When deploying Airdrops test data, campaigns are created via factory:

Factory	Campaign Contract
SablierFactoryMerkleInstant	SablierMerkleInstant
SablierFactoryMerkleLL	SablierMerkleLL
SablierFactoryMerkleLT	SablierMerkleLT
SablierFactoryMerkleVCA	SablierMerkleVCA

Campaign addresses are returned in broadcast returns field, not contractAddress.
