Build production-ready Web3 applications, smart contracts, and decentralized systems. Implements DeFi protocols, NFT platforms, DAOs, and enterprise blockchain integrations. Use PROACTIVELY for smart contracts, Web3 apps, DeFi protocols, or blockchain infrastructure.
How to build, sign, submit, and simulate transactions in @aptos-labs/ts-sdk. Covers build.simple(), signAndSubmitTransaction(), waitForTransaction(), simulate, sponsored (fee payer), and multi-agent. Triggers on: 'build.simple', 'signAndSubmitTransaction', 'transaction.build', 'waitForTransaction', 'signAsFeePayer', 'SDK transaction', 'sponsored transaction', 'multi-agent transaction'.
Expert guidelines for blockchain development including CosmWasm, Cosmos, and cross-chain patterns
How to create, manage, and transfer tokens on Hedera using the Hiero JavaScript SDK (@hiero-ledger/sdk). Use this skill whenever the user wants to work with fungible tokens, NFTs, token creation, minting, burning, transfers, token association, custom fees (fixed, fractional, royalty), airdrops, KYC/freeze/wipe/pause operations, or any HTS (Hedera Token Service) operation in JavaScript or TypeScript. Also trigger when users mention @hashgraph/sdk token operations, ERC-20/ERC-721 equivalents on Hedera, or tokenization on the Hedera network.
TON Blueprint development environment — project layout, build/test/run, NetworkProvider, config, scripts, wrappers, and deploy/testing practices.
Expert-level blockchain, Web3, smart contracts, DeFi, and cryptocurrency development
AlgoKit Utils library for interacting with the Algorand blockchain from TypeScript or Python applications. Use when connecting to Algorand networks (LocalNet, TestNet, MainNet), sending payments or transferring assets, creating and managing accounts, deploying or interacting with smart contracts from client code, or composing transaction groups. NOT for writing smart contract code (use build-smart-contracts skill). Strong triggers include "How do I connect to Algorand?", "send a payment transaction", "create an account", "deploy my contract", "get an AlgorandClient", "AlgorandClient.fromEnvironment".
Use Light Token client SDKs (TypeScript and Rust) to create mints, associated token accounts, transfer, approve, burn, wrap, and more. Cookbook for @lightprotocol/compressed-token and light_token_client.
Add more vault smart contract types to an existing protocol
Complete Polygon agent CLI. Session-based smart contract wallets (Sequence), token ops (send/swap/bridge/deposit via Trails), ERC-8004 on-chain identity + reputation, x402 micropayments. Single CLI entry point, AES-256-GCM encrypted storage.
Use when building blockchain applications or smart contracts across EVM (Solidity), Solana (Anchor/Rust), Cosmos (CosmWasm), and TON, including security/audit workflows, fuzz/invariant testing, upgrades, custody/signing, and backend integration (RPC, indexers, webhooks).
TypeScript patterns for low-level EVM blockchain interactions using Viem. Use when writing Node scripts, CLI tools, or backend services that read/write to Ethereum or EVM chains. Triggers on contract interactions, wallet operations, transaction signing, event watching, ABI encoding, or any non-React blockchain TypeScript code. Do NOT use for React/Next.js apps with hooks (use wagmi skill instead).
