Tools that do one thing right. No signup, no clutter — just useful Web3 utilities for builders.
Paste your smart contract ABI and generate categorized function selectors instantly. Filter by payable, view, pure, and more. Built for Solidity developers.
Paste any Solidity smart contract ABI to instantly extract a clean interface with only the functions — perfect for audits, proxies, and modular contracts. No events, no constructors, just the essentials.
Perform low-level bitwise operations on 256-bit integers. Shift, mask, toggle, and inspect specific bits. Useful for calldata encoding, role-based access, and optimizing storage in smart contracts.
Hash any input using keccak256, sha256, or sha512. Works for Ethereum, Solana, and general Web3 use cases.
Generate a Merkle root and wallet proofs for EVM-compatible chains like Ethereum, Polygon, BNB, Arbitrum, Optimism, and Base. We use keccak256 hashing and hex-encoded addresses, fully compatible with Solidity smart contracts and OpenZeppelin's MerkleProof.
Generate a Merkle root and wallet proofs from Solana addresses — perfect for whitelists, claimlists, airdrops, and contract setups. We use base58-decoded raw bytes (bs58) and SHA-256 hashing to ensure compatibility with Solana smart contracts.
Convert SOL to lamports and vice versa - perfect for smart contract configs, token pricing, and Solana development.
Get 2 SOL every 12 hours to test and deploy on Solana Devnet
Convert Unix timestamps to readable dates and back — built for smart contract developers, not calendars.
