surfpool

surfpool is a skill for Claude Code, Codex from sendaifun/skills. It costs 49 tokens per session (3,019 once invoked), scanned C, original, Apache-2.0.

A local development environment for Solana, a blockchain platform. It can simulate programs using data copied from Solana’s live main network, with tools for controlling test state and inspecting transactions.

In plain words
What is it for?
Use it to develop and test Solana programs, reproduce deployments, manipulate test conditions, inspect transactions, and obtain test SOL or tokens.
Why use it?
It lets developers test against realistic accounts, tokens, and balances without setting up or copying the entire live network.

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.

Security

Grade C, and why

surfpool scanned grade C with 2 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 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (examples/basic/getting-started.ts, examples/cheatcodes/state-manipulation.ts, templates/test-setup.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Surfpool - Solana Development Environment

The definitive guide for Surfpool - where developers start their Solana journey. A drop-in replacement for solana-test-validator that enables local program simulation using Mainnet accounts fetched just-in-time.

What is Surfpool?

Surfpool is a comprehensive development environment that combines local-first testing with real Mainnet data access:

  • Mainnet Forking - Clone accounts, programs, and token balances from Mainnet instantly
  • Cheatcodes - Special RPC methods for time travel, balance manipulation, and state control
  • Infrastructure as Code - Reproducible, auditable deployments using txtx DSL
  • Surfpool Studio - Embedded dashboard with transaction inspection and profiling
  • Universal Faucet - Get SOL, USDC, USDT, BONK from a single interface

Key Benefits

Feature Description
Instant Boot No 2TB snapshots, runs on Raspberry Pi
Lazy Forking Copy-on-read strategy pulls mainnet data as needed
Full Compatibility Works with solana-cli, Anchor, wallets, explorers
Zero Config Auto-detects Anchor projects and deploys programs

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.
