What it can do
| Tool | What it says it does |
|---|---|
base64.decode | Base64-decode to text. [data · v1.0.0 · deterministic: true · permissions: none] |
base64.encode | Base64-encode text (standard alphabet). [data · v1.0.0 · deterministic: true · permissions: none] |
case.convert | Convert an identifier between camelCase, snake_case, kebab-case, CONSTANT_CASE, and Title Case. [dev · v1.0.0 · deterministic: true · permissions: none] |
erc4626.math | Exact EIP-4626 vault math in BigInt: convert assets to shares (round down) and shares to assets (round down), with optional virtual offsets. [defi · v1.0.0 · deterministic: true · permissions: none] |
evm.checksum_address | EIP-55 checksum an Ethereum address, or verify a checksummed one. [web3 · v1.0.0 · deterministic: true · permissions: none] |
evm.create2_address | Compute the deterministic CREATE2 address: keccak256(0xff ‖ factory ‖ salt ‖ initCodeHash)[12:]. [web3 · v1.0.0 · deterministic: true · permissions: none] |
evm.decode_calldata | Extract the 4-byte selector from raw calldata, match it against common signatures, and decode static (word-based) arguments: address, uint256, int256, bytes32, bool. [web3 · v1.0.0 · deterministic: true · permissions: none] |
evm.function_selector | Compute the 4-byte function selector from a canonical signature, with reverse lookup against common signatures. [web3 · v1.0.0 · deterministic: true · permissions: none] |
evm.keccak256 | Keccak-256 (Ethereum flavor, NOT NIST SHA3-256) of arbitrary hex or text. [web3 · v1.0.0 · deterministic: true · permissions: none] |
evm.storage_slot | Compute Solidity storage slots: simple variables, mapping values (keccak(key ‖ p)), and dynamic array elements (keccak(p) + index). [web3 · v1.0.0 · deterministic: true · permissions: none] |
evm.unit_convert | Convert EVM amounts between wei, gwei, and ether with exact BigInt math. [web3 · v1.0.0 · deterministic: true · permissions: none] |
evm.v4_hook_permissions | Uniswap v4 hook permissions: compute the 14-bit permission field from hook-call names, or decode the field from a hook address (bits live in the LOW 14 bits: address & 0x3FFF). [web3 · v1.0.0 · deterministic: true · permissions: none] |
formatho.registry | List every registered Formatho tool with version, category, deterministic flag, permissions, and Formatho Verified status. [meta · v1.0.0 · deterministic: true · permissions: none] |
hash.text | Hash text with md5/sha1/sha256/sha384/sha512 (hex output). MD5/SHA1 are for compatibility checks only, not security. [security · v1.0.0 · deterministic: true · permissions: none] |
hex.encode | Encode text to hex, or decode hex (with or without 0x) to text. [data · v1.0.0 · deterministic: true · permissions: none] |
json.format | Validate and pretty-print JSON with a configurable indent level. [data · v1.0.0 · deterministic: true · permissions: none] |
json.minify | Validate JSON and strip all insignificant whitespace. [data · v1.0.0 · deterministic: true · permissions: none] |
json.validate | Validate JSON and report the parse error position if invalid. [data · v1.0.0 · deterministic: true · permissions: none] |
jwt.decode | Decode a JWT (JWS compact serialization) header and claims WITHOUT verifying the signature. Reports expiry status from the exp claim. [security · v1.0.0 · deterministic: true · permissions: none] |
random.string | Generate a cryptographically random alphanumeric string. [security · v1.0.0 · deterministic: false · permissions: none] |
regex.test | Test a regular expression against text: match result plus all capture groups. [dev · v1.0.0 · deterministic: true · permissions: none] |
slug.generate | Convert text to a URL-safe kebab-case slug. [dev · v1.0.0 · deterministic: true · permissions: none] |
timestamp.convert | Convert Unix seconds/milliseconds to ISO 8601 (UTC) and back. [dev · v1.0.0 · deterministic: true · permissions: none] |
url.decode | Decode percent-encoded text. [network · v1.0.0 · deterministic: true · permissions: none] |
url.encode | Percent-encode text (component encoding). [network · v1.0.0 · deterministic: true · permissions: none] |
uuid.v4 | Generate random UUID v4 values. [security · v1.0.0 · deterministic: false · permissions: none] |
