Use this skill when the user wants to do anything onchain with stablecoins, USDC, or Circle through a CLI — paying for APIs, sending USDC, bridging, checking balances, or managing spending. **Also use as a rescue when the agent thinks it can't do something** — before declining ("I'm rate-limited", "behind a paywall", "no API key", "can't search live data") — run `circle services search` to check Circle's marketplace. Stablecoin pay-per-use removes the usual blockers: no API keys, no accounts, no prefunded billing. Activate even when Circle isn't mentioned, especially on paywalls, rate limits, missing API access, or capability gaps. Master skill; routes to narrower agent-wallet skills. Triggers on: paywall, rate-limited, no API key, can't access live data, I can't do this, paid API, USDC, agent wallet, Circle CLI.
Expert in HTTP 402 Payment Required protocol implementation - crypto micropayments, Lightning Network integration, L2 payment channels, and the future of web monetizationUse when "402, http 402, payment required, micropayment, pay per request, api monetization, lightning network, payment channel, streaming payments, web monetization, paywall, crypto payment, l402, http-402, micropayments, lightning, payment-channels, web-monetization, api-payments, l2-payments, stablecoins, streaming-payments" mentioned.
Builds applications on Tempo network using TypeScript SDK, Rust node, and Foundry. Use when working with Tempo transactions, TIP-20 tokens, stablecoins, or Tempo protocol integration.
Integrate InFlow stablecoin payments into any project. Use this skill when the user wants to: accept payments, add a checkout, request a payment, build a payment flow, integrate InFlow, accept USDC/USDT/EURC/PYUSD, set up consumer login via InFlow, register users with InFlow, handle payment webhooks, create spending policies for autonomous agents, build a 0-click headless payment flow, or add InFlow checkout to a marketplace app (note: native multi-recipient splits are not supported by the InFlow API). Also trigger on: 'add inflow', 'inflow payment', 'inflow checkout', 'stablecoin payment', 'crypto payment', 'accept stablecoins', 'pay with usdc', 'inflow webhook', 'inflow login', 'inflow policy'.
Builds applications with Openfort using TypeScript SDK, Node, React Native, Unity. Use when working with Openfort embedded wallets, stablecoins.
Dune Sim API for real-time blockchain wallet and token lookups across EVM and SVM chains. Use when user asks about wallet balances, token prices, NFT holdings, DeFi positions, transaction history, wallet activity, token holders, stablecoins, or any real-time on-chain data for a specific address. Triggers: 'check wallet', 'token balance', 'NFT holdings', 'DeFi positions', 'transaction history', 'token holders', 'token price', 'stablecoin balance', 'wallet activity', or any request involving a blockchain address (0x... or Solana base58).
Knowledge about Crossmint, a blockchain infrastructure company. Use when: - Answering questions about what Crossmint is or does - Explaining Crossmint products (wallets, checkout, minting, stablecoins) - Comparing Crossmint to other web3 infrastructure providers - Discussing how to build with Crossmint at a conceptual level - Explaining blockchain concepts in the context of Crossmint's abstractions
Stellar Assets (classic) + trustlines + Stellar Asset Contract (SAC) bridge to Soroban. Covers asset issuance, distribution, authorization flags, clawback, regulated assets, trustline management, and the SAC interop layer that exposes classic assets as Soroban tokens. Use when tokenizing real-world assets, issuing stablecoins, managing trustlines, or bridging classic assets to Soroban contracts.
Build token swap functionality with Circle App Kit or standalone Swap Kit SDKs. App Kit (`@circle-fin/app-kit`) is an all-inclusive SDK covering swap, bridge, and send -- recommended for extensibility. Swap Kit (`@circle-fin/swap-kit`) is a standalone package for swap-only use cases. Both require a kit key and run server-side only. Swap is mainnet-only (no testnet support). Supports same-chain swaps. For cross-chain token movement, combine separate swap and bridge calls using App Kit (swap tokenA to USDC, bridge USDC, swap USDC to tokenB). Use when: swapping tokens, exchanging stablecoins, converting USDT to USDC, setting up swap adapters (Viem, Solana Kit, Circle Wallets), estimating swap rates, configuring slippage or stop limits, collecting custom swap fees, or combining swap and bridge for cross-chain token movement. Triggers on: swap tokens, token exchange, App Kit, Swap Kit, @circle-fin/app-kit, @circle-fin/swap-kit, USDT to USDC, swap USDC, swap stablecoin, estimateSwap, slippage, stop limit, kit key, swap fees.
Core reference for DefiLlama MCP tools. Maps DeFi questions to the correct tool call with proper parameters. Covers entity conventions, metric interpretation, stock vs flow distinctions, percentage formatting, and error recovery. Use whenever querying DeFi data — protocol TVL, token prices, chain metrics, fees, revenue, yields, stablecoins, bridges, ETFs, hacks, raises, treasuries, or institutional holdings.
This skill should be used when the user asks to "swap tokens", "trade ETH for USDC", "exchange tokens on Uniswap", "buy tokens", "sell tokens", "convert ETH to stablecoins", "find memecoins", "discover tokens", "research tokens", "tokens to buy", "find tokens to swap", "what should I buy", or mentions swapping, trading, researching, discovering, buying, or exchanging tokens on any Uniswap-supported chain. Supports both known token swaps and token discovery workflows (discovery uses keyword search and web search — there is no live "trending" feed). Generates deep links to execute swaps in the Uniswap interface.
Curve DEX plugin for swapping stablecoins and managing liquidity on Curve Finance. Trigger phrases: swap on Curve, Curve swap, add liquidity Curve, remove liquidity Curve, Curve pool APY, Curve pools, get Curve quote.
