Web3, smart contracts, and specialized crypto tools.
Scans Substrate/Polkadot pallets for 7 critical vulnerabilities including arithmetic overflow, panic DoS, incorrect weights, and bad origin checks. Use when auditing Substrate runtimes or FRAME pallets. (project, gitignored)
Scans Solana programs for 6 critical vulnerabilities including arbitrary CPI, improper PDA validation, missing signer/ownership checks, and sysvar spoofing. Use when auditing Solana/Anchor programs. (project, gitignored)
Universal contractual development mode enforcer. Reads project-specific rules from CLAUDE.md dynamically. Activate for any project requiring verified claims, security checks, evidence-based recommendations, or strict development standards. Triggers: /c-framework, /cf, "modo contractual", "verify code", "enforce rules", "contract mode". Works with any stack (Node, Python, Go, etc.) and any project type (API, SaaS, CLI, web-app).
Use when building applications on the Hedera network, creating accounts and tokens, deploying smart contracts, submitting transactions, querying network data, or working with consensus services. Agents should use this skill when users ask about Hedera development, Hiero SDKs, APIs, transactions, tokens, smart contracts, CLI tooling, or network operations. Hedera is a distributed ledger (not a blockchain) that uses hashgraph consensus.
Production-grade project structure patterns for MultiversX smart contracts.
Atomic lend-execute-verify pattern — reentrancy guards, shard validation, endpoint checks.
Factory pattern for deploying and managing child contracts from a template.
Identify and analyze MultiversX Smart Contract entry points (#[endpoint],
Read another contract's storage directly using storage_mapper_from_address for same-shard contracts.
Envelope encryption patterns with X25519 for agent memories. Use when implementing key generation, DEK management, encrypting/decrypting records, key rotation, or sharing encrypted data between agents. Triggers on encryption, X25519, DEK, envelope encryption, key exchange, crypto.
Smart contract operations for MultiversX TypeScript/JavaScript SDK.
Bitcoin vanity address generator with regex pattern matching and GPU acceleration. Use when generating Bitcoin/Ethereum vanity addresses, scanning key ranges for Bitcoin Puzzles, or verifying private keys against addresses. Supports P2PKH, P2WPKH, P2SH-P2WPKH, P2TR, and Ethereum formats.
Create and manage Safe multi-signature wallets on Abstract — deploy new Safes, configure owners and thresholds, propose and execute multi-sig transactions using the Safe SDK or the Safe UI. This skill should be used when working with Safe on Abstract, creating a multisig wallet on Abstract, safe.abs.xyz, Safe Protocol Kit on Abstract, multi-sig transactions, SafeL2, SafeProxyFactory, or managing shared wallets with multiple signers on Abstract.
Abstract network configuration — chain IDs, RPC endpoints, WebSocket URLs, block explorers, and wallet setup for the Abstract Ethereum L2. This skill should be used when configuring clients, wallets, or dev environments for Abstract, including questions about Abstract RPC URLs, chain IDs (2741/11124), testnet config, Abscan explorer, connecting to the Abstract network, or importing abstract/abstractTestnet from viem/chains.
Integrate Abstract Global Wallet (AGW) into React applications — email/social/passkey login, smart contract wallet, session keys, gas sponsorship, and wallet provider integrations for the Abstract Ethereum L2. This skill should be used when working with AGW, AbstractWalletProvider, useLoginWithAbstract, useAbstractClient, useWriteContractSponsored, agw-react, agw-client, create-abstract-app, session keys on Abstract, or gas-sponsored transactions on Abstract.
This skill should be used when the user asks to "send a payment", "check balance", "list transactions", "create a quote", "manage customers", "create external account", "what currencies does Grid support", "how do I use the Grid API", "send money to [country]", "pay [UMA address]", "send to CLABE", "send to PIX", "send to IBAN", "send to UPI", "fund sandbox account", "test a payment", "on-ramp", "off-ramp", "convert crypto to fiat", "convert fiat to crypto", "look up UMA", "real-time quote", "JIT funding", "check exchange rate", "FX rate", "payment corridor", "what rate will I get", "estimate withdrawal fee", "crypto withdrawal fee", or any payment operations using the Grid API CLI.
Cross-chain token swap integration using NEAR Intents 1Click API. Use when building swap widgets, bridge interfaces, or multi-chain transfers across EVM, Solana, NEAR, TON, Stellar, and Tron.
Guide for developing with near-api-js v7 - the JavaScript/TypeScript library for NEAR blockchain interaction. Use when: (1) building apps that interact with NEAR blockchain, (2) creating/signing transactions, (3) calling smart contracts, (4) managing accounts and keys, (5) working with NEAR RPC API, (6) handling FT/NFT tokens on NEAR, (7) using NEAR cryptographic operations (KeyPair, signing), (8) converting between NEAR units (yocto, gas), (9) gasless/meta transactions with relayers, (10) NEP-413 message signing for authentication, (11) storage deposit management for FT contracts. Triggers on any NEAR blockchain development tasks.
Build NEAR Protocol dApps. Use for: (1) creating new NEAR dApps with `create-near-app` (Vite+React, Next.js), (2) adding NEAR wallet connection to existing apps with `@hot-labs/near-connect` and `near-connect-hooks`, (3) building frontend UI for NEAR smart contracts, (4) integrating wallet sign-in/sign-out, contract calls, and transaction signing into web applications.
