What is evm-deployment?

A workflow guide for deploying Sablier’s EVM smart contracts, which are programs that run on compatible blockchains. It covers contract packages such as Flow, Lockup, Airdrops, and Bob.

Use it when deploying Sablier contracts to a blockchain network and updating the related software development kit.

It organizes deployment, blockchain explorer verification, SDK updates, and initial setup into one process.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add sablier-labs/agent-skills --skill evm-deployment

Clone the repo

git clone --depth 1 https://github.com/sablier-labs/agent-skills

Made for: Claude Code, Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00076	$0.01078
Opus 5.5	$0.00030	$0.00431
Sonnet 5.5	$0.00015	$0.00216
Haiku 4.5	$0.00008	$0.00108

Security

Grade A, and why

evm-deployment scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Overview

End-to-end deployment workflow for Sablier EVM contracts. Supports Utils, Flow, Lockup, Airdrops, and Bob 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`	Utils	`../sdk/deployments/comptroller`
`@sablier/flow`	Flow	`../sdk/deployments/flow`
`@sablier/lockup`	Lockup	`../sdk/deployments/lockup`
`@sablier/airdrops`	Airdrops	`../sdk/deployments/airdrops`
`@sablier/bob`	Bob	`../sdk/deployments/bob`

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: Initial Setup (optional)

Reference: ./references/init-setup.md

Creates initial setup for deployed contracts:

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

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

evm-deployment is a skill published in the GitHub repository sablier-labs/agent-skills (9 stars, last pushed 1mo ago), licensed MIT. It adds 76 tokens to every session and 1,078 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
