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

Create a Surfpool.toml in your project root:

[network]
slot_time = 400
epoch_duration = 432000
rpc_url = "https://api.mainnet-beta.solana.com"

[behavior]
# Fork from mainnet genesis
genesis = false
# Fork from specific point
point_fork = true

[accounts]
# Pre-clone specific accounts
clone = [
  "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA",  # Token Program
  "ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL", # ATA Program
]

[programs]
# Auto-deploy local programs
deploy = ["./target/deploy/my_program.so"]

[airdrop]
# Default airdrop recipients
addresses = ["YOUR_PUBKEY"]
amount = 10000000000000  # 10,000 SOL

Cheatcodes

Surfpool provides special RPC methods for advanced state manipulation during testing.

Account Manipulation

surfnet_setAccount

Set arbitrary account data:

await connection.send("surfnet_setAccount", [
  {
    pubkey: "AccountPubkey...",
    lamports: 1000000000,
    data: "base64EncodedData",
    owner: "OwnerPubkey...",
    executable: false,
  },
]);
surfnet_setTokenAccount

Create or modify token accounts:

await connection.send("surfnet_setTokenAccount", [
  {
    owner: "OwnerPubkey...",
    mint: "MintPubkey...",
    tokenProgram: "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA",
    update: {
      amount: "1000000000",
      delegate: null,
      state: "initialized",
    },
  },
]);
surfnet_cloneProgramAccount

Clone a program from mainnet:

await connection.send("surfnet_cloneProgramAccount", [
  {
    source: "SourceProgramPubkey...",
    destination: "DestinationPubkey...",
  },
]);
surfnet_resetAccount

Reset account to mainnet state:

await connection.send("surfnet_resetAccount", [
  {
    pubkey: "AccountPubkey...",
    includeOwnedAccounts: true,
  },
]);

Time Control

surfnet_timeTravel

Advance network time:

await connection.send("surfnet_timeTravel", [
  {
    epoch: 100,
    slot: 50000,
    timestamp: 1700000000,
  },
]);
surfnet_pauseClock / surfnet_resumeClock

Control block production:

// Pause
await connection.send("surfnet_pauseClock", []);

// Resume
await connection.send("surfnet_resumeClock", []);
surfnet_advanceClock

Advance clock incrementally:

await connection.send("surfnet_advanceClock", [
  { slots: 100 },
]);

Transaction Profiling

surfnet_profileTransaction

Profile transaction execution:

const result = await connection.send("surfnet_profileTransaction", [
  {
    transaction: "base64EncodedTx",
    tag: "my-test-tag",
  },
]);

console.log("Compute units:", result.computeUnits);
console.log("Account changes:", result.accountChanges);
surfnet_getProfileResults

Get profiling results by tag:

const results = await connection.send("surfnet_getProfileResults", [
  { tag: "my-test-tag" },
]);

Network Control

surfnet_resetNetwork

Reset entire network to initial state:

await connection.send("surfnet_resetNetwork", []);
surfnet_getClock

Get current network time:

const clock = await connection.send("surfnet_getClock", []);
console.log("Slot:", clock.slot);
console.log("Epoch:", clock.epoch);
console.log("Timestamp:", clock.timestamp);

Surfpool Studio

Access the web dashboard at http://127.0.0.1:18488 for:

  • Transaction Inspector - View transaction details with byte-level diffs
  • Account Browser - Explore account state and history
  • Compute Profiler - Analyze compute unit usage per instruction
  • Universal Faucet - Request SOL and tokens
  • Network Status - Monitor slots, epochs, and block production

Infrastructure as Code

Surfpool integrates txtx DSL for reproducible deployments.

Runbook Structure

# deployment.tx

// Define signers
signer "deployer" "svm::secret_key" {
  secret_key = env.DEPLOYER_KEY
}

// Deploy program
action "deploy_program" "svm::deploy_program" {
  program_path = "./target/deploy/my_program.so"
  signer = signer.deployer
}

// Initialize program
action "initialize" "svm::send_transaction" {
  transaction {
    instruction {
      program_id = action.deploy_program.program_id
      data = encode_instruction("initialize", {})
    }
  }
  signers = [signer.deployer]
}

Running Runbooks

# Run specific runbook
surfpool start -r deployment

# Run in unsupervised mode
surfpool start -r deployment --unsupervised

Scenarios and Fixtures

Scenarios

Define account state sequences for testing:

await connection.send("surfnet_registerScenario", [
  {
    name: "high-volume-trading",
    slots: [
      {
        slot: 100,
        accounts: {
          "PoolPubkey...": { lamports: 1000000000000 },
        },
      },
      {
        slot: 200,
        accounts: {
          "PoolPubkey...": { lamports: 500000000000 },
        },
      },
    ],
  },
]);

Fixtures

Export transaction fixtures for reproducible tests:

const fixture = await connection.send("surfnet_exportSnapshot", [
  {
    transaction: "txSignature...",
    format: "json",
  },
]);

// Save fixture for CI/CD
fs.writeFileSync("fixtures/my-test.json", JSON.stringify(fixture));

Integration with Anchor

Surfpool auto-detects Anchor projects and handles deployment:

# In an Anchor project directory
surfpool start
# Programs in target/deploy/ are automatically deployed

Testing with Anchor

import * as anchor from "@coral-xyz/anchor";

describe("My Program", () => {
  // Use local Surfnet
  const provider = anchor.AnchorProvider.local("http://127.0.0.1:8899");
  anchor.setProvider(provider);

  it("works with mainnet state", async () => {
    // Your tests automatically have access to mainnet accounts
  });
});

Best Practices

1. Use Cheatcodes for Setup

// Set up test state before each test
beforeEach(async () => {
  await connection.send("surfnet_resetNetwork", []);
  await connection.send("surfnet_setTokenAccount", [...]);
});

2. Profile Critical Paths

// Tag transactions for profiling
const result = await connection.send("surfnet_profileTransaction", [
  { transaction: tx, tag: "swap-operation" },
]);

expect(result.computeUnits).toBeLessThan(200000);

3. Use Scenarios for Edge Cases

// Test with specific mainnet conditions
await connection.send("surfnet_registerScenario", [
  { name: "low-liquidity", slots: [...] },
]);

4. Export Fixtures for CI

// Create reproducible test fixtures
const fixture = await connection.send("surfnet_exportSnapshot", [...]);

How to use it

Copy the folder

Take sendaifun/surfpool from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference brew, docker. Without those the skill loads but fails at the first command.
