Master the Entire Smart Contract Lifecycle.

From gas forecasting and mainnet forking to automated security audits and real-time on-chain monitoring, Blocktools is the essential Rust-powered suite for professional Web3 developers.

A Cohesive Development Workflow

Stop jumping between frameworks, websites, and complex setups. Our suite provides a single, high-performance toolchain for the tasks you perform every day.

1. Develop & Test on a Live Fork

Start by forecasting costs with gas-forecaster. Then, use sol-console to instantly spin up a local fork of any EVM mainnet. Interact with your contract against real, live on-chain data from protocols like Uniswap or Aave—no mock data, no complex setup. It's the highest-fidelity testing environment you can get.

$ # Instantly interact with mainnet Uniswap from a local fork
$ sol-console --from-etherscan 0x1f98... --fork-url $MAINNET_RPC

> contract.name()
<- "Uniswap"
> contract.balanceOf("vitalik.eth")
<- 550000000000000000000

2. Secure & Generate Tests

Continuously secure your codebase with sol-sentry, which automatically scans for critical vulnerabilities on every commit via its Git hook. Then, use sol-console's `record` command to turn your manual testing sessions into ready-to-use Foundry test scripts, complete with function calls and assertions.

$ sol-sentry scan .
🚨 Found 1 issues in contracts/Vulnerable.sol

[CRITICAL] Unprotected State-Changing Function
- Line: 25, Details: `setOwner` is public...

$ # After fixing, record a test session
$ sol-console --contract-path ./Fixed.sol --standalone
> record start
> contract.doSomething(123)
> assert.eq(contract.getSomething(), 123)
> record stop --as=foundry
> Test file generated at test/Fixed.t.sol

3. Analyze & Monitor On-Chain

For post-deployment, you need total visibility. Use receipt-parse to turn any cryptic transaction hash into a beautiful, human-readable report. For live monitoring, use event-tail to get a real-time `tail -f` style stream of any event from your contracts, right in your terminal.

$ # Get a real-time feed of NFT mints
$ event-tail --address 0xBC4... --event Transfer

Proof in Production

We use our own tools to build battle-tested, open-source solutions you can use today.

Featured Solution: Gas-Efficient Batch Sender

Need to airdrop ETH or tokens to thousands of users? Use our pre-built, Merkle-based solution. It was planned with gas-forecaster, secured by sol-sentry, and is ready for mainnet. A perfect example of the Blocktools workflow in action.
