Cryptocurrency ChatGPT Plugins

See also: ChatGPT Plugins, ChatGPT Plugin Categories and Cryptocurrency

Cryptocurrency ChatGPT Plugins were a category of third-party extensions for ChatGPT that connected the assistant to live crypto market data, on-chain blockchain data, decentralized finance (DeFi) analytics, smart contract analysis, NFT collections, and crypto security feeds. They were available to ChatGPT Plus subscribers from March 23, 2023, when OpenAI introduced the plugins protocol, until April 9, 2024, when OpenAI shut down the plugin beta in favor of Custom GPTs and the GPT Store. OpenAI described plugins as "tools designed specifically for language models with safety as a core principle" that "help ChatGPT access up-to-date information, run computations, or use third-party services" ^[1], and cryptocurrency became one of the most populated verticals in a store that grew past 1,000 plugins by early 2024 ^[2][23]. Entries came from data providers (CoinMarketCap, CCData, DefiLlama), blockchain platforms (Solana Labs, Alchemy), security companies (GoPlus), and a long tail of independent developers.

What are cryptocurrency ChatGPT plugins?

Cryptocurrency ChatGPT plugins were natural language wrappers over crypto APIs and block explorers, letting a ChatGPT Plus user ask for live prices, on-chain reads, DeFi metrics, NFT data, and contract risk in plain English instead of querying a dashboard or RPC node directly. Cryptocurrency was an obvious early fit for the plugin protocol because the asset class produces a constant stream of public, structured data that a large language model cannot answer from training data alone. Token prices, on-chain transactions, DeFi protocol total value locked (TVL), NFT floor prices, and smart contract source code all change minute by minute, and crypto users were already comfortable with APIs and block explorers. Plugin developers turned the chat surface into a natural language wrapper over their own services.

A cryptocurrency plugin typically published an ai-plugin.json manifest at the /.well-known/ path, an OpenAPI specification, and a hosted backend returning JSON. ChatGPT decided when a crypto question warranted an external call, formatted the call to match the OpenAPI schema, sent it through the plugin runtime, and summarized the response. Plugin invocations required a GPT-4 chat session and a ChatGPT Plus subscription, which OpenAI priced at $20 per month ^[3]. The same routing primitives became the direct ancestor of the actions feature in Custom GPTs.

Crypto plugins broke into six functional groups: market data, DeFi analytics, on-chain blockchain access, NFT analysis, smart contract and security review, and Web3 employment. Boundaries were fuzzy: CoinMarketCap and CCData mixed prices with news, SignalPlus mixed prices with derivatives metrics and NFT rankings, and Solana Labs mixed RPC reads with NFT marketplace queries.

When did cryptocurrency ChatGPT plugins launch and shut down?

The plugin beta launched on March 23, 2023 and was fully deprecated on April 9, 2024, a run of roughly 12.5 months. New plugin installs and new plugin-powered conversations were disabled earlier, on March 19, 2024 ^[2]. The crypto-specific plugins arrived between late April and October 2023, after OpenAI widened access to all ChatGPT Plus subscribers on May 12, 2023.

Which plugins gave crypto prices?

The most-used crypto plugins were the price and market-data plugins: CoinMarketCap, CCData, Crypto Prices, CoinCap, and the Polygon (later Massive) plugin. They let users ask for spot prices, conversions, market caps, and trending tokens without leaving the chat.

CoinMarketCap

CoinMarketCap published its plugin on October 11, 2023, marketing it as "your own crypto analyst intern" for every ChatGPT user ^[3]. It connected ChatGPT to CoinMarketCap's public API: current and historical prices, market capitalization, trading volume, circulating supply, and trending tokens. Because ChatGPT could chain calls in a conversation, users could ask comparative questions such as the correlation between Bitcoin and Ethereum price action, or how Bitcoin performed in the month leading up to past US elections ^[3]. Access required ChatGPT Plus with GPT-4 at $20 per month; CoinMarketCap did not charge an additional fee ^[3].

CCData

CCData, formerly CryptoCompare, ran one of the earliest cryptocurrency-specific plugins. It pulled from CCData's CCIX index (previously CCCAGG), which aggregates trade prints across major exchanges, and supplied current prices, historical price series, and one-day OHLC candlestick intervals. It also surfaced recent news articles tagged to specific assets. Both endpoints were free.

How did the on-chain and blockchain plugins work?

On-chain plugins from Solana Labs and Alchemy exposed RPC-style reads through chat, letting users ask for balances, transactions, NFT holdings, and block content directly rather than running a node query themselves.

Solana Labs plugin

Solana Labs was the first major blockchain platform to ship a ChatGPT plugin, which it described as the first integration of a Layer 1 network with ChatGPT ^[6]. A beta went up on GitHub in late April 2023, and the public version followed on May 23, 2023 at chatgpt.solanalabs.com. The plugin connected to a Solana RPC node and exposed account, balance, token, and transaction reads, plus NFT discovery via the Metaplex Read API and collection floor price browsing through Hyperspace. Total portfolio value, segmented between NFTs and tokens, was supplied by HelloMoon. SolanaPay QR codes let users sign transactions by scanning a code rendered inside the chat. Tal Tchwella, then head of product at Solana Labs, framed the plugin as an onboarding tool, telling TechCrunch, "We believe that the blockchain space is way too technical" ^[6]. The repository was archived in January 2025.

Alchemy

Alchemy announced AlchemyAI on June 14 and 15, 2023, packaging two products: an in-dashboard developer assistant called ChatWeb3 and a ChatGPT plugin on the same back end ^[9][10]. The plugin translated natural language into requests against the Alchemy API across Ethereum, Polygon, Arbitrum, and Optimism, returning answers about recent blocks, transactions, balances, NFT metadata, and gas prices. Alchemy gave the canonical example of typing "Show me the most recent block and the transactions in that block" and receiving a formatted answer ^[9], and explicitly warned users to cross-check responses against block explorers.

How did the DeFi and trading plugins work?

DeFi and derivatives plugins let users compare protocols and markets quantitatively, turning questions that previously needed SQL on Dune or subgraph queries into plain-English prompts.

DefiLlama

The DefiLlama plugin was built by a community contributor known as Kofi and entered open beta in June 2023 ^[13][14]. It exposed the same dataset that powers the DefiLlama dashboards: TVL by protocol and chain, historical TVL series, protocol fees and revenue, category rankings, and bridge volumes. DefiLlama stated the plugin did not collect identifying user data or include sponsored content ^[13].

SignalPlus

SignalPlus released its plugin on June 30, 2023 as a comprehensive crypto trading assistant ^[11]. It supported OHLCV data for spot, futures, and perpetuals; funding rates; long and short ratios with open interest; liquidation statistics; gas prices across major blockchains; smart contract intelligence; NFT rankings; trending coins on CoinGecko; and DeFi protocol TVL.

Were there crypto security plugins?

Yes. GoPlus Security, Smarter Contracts, and Crypto ERC20 Scout let users run pre-trade due diligence on a token or contract from inside ChatGPT.

GoPlus Security AI

GoPlus Security published its plugin on August 16, 2023, wrapping the GoPlus Security API ^[12]. GoPlus said the plugin was meant to make "user security accessible, comprehensible, and actionable for everyone, not just developers" ^[12]. It answered questions about token contract risks (mint authority, blacklist functions, ownership concentration), known malicious addresses, NFT authenticity, approval safety, dApp risk profiles, and decoded function signatures from raw calldata. Phishing site detection and rug pull detection were in beta. It was a notable early example of consumer-facing AI security tooling for retail crypto users.

Smarter Contracts and Crypto ERC20 Scout

Smarter Contracts analyzed smart contracts on Ethereum, Polygon, and other EVM-compatible networks. Given a contract address and chain, it parsed functions, events, tokenomics, and metadata; for ERC721 and ERC1155 contracts it surfaced ownership and minting details; it also resolved Ethereum Name Service (ENS) names. Crypto ERC20 Scout, at chatgpt.erc20list.org, browsed indexed token lists across Ethereum, Arbitrum, Polygon, Optimism, xDai, and other EVM chains, returning addresses, explorer links, and CoinGecko-sourced prices.

What about news, sentiment, and jobs plugins?

Bitcoin Sentiment, Crypto Pulse, and Crypto Market News

Bitcoin Sentiment, by Orren Prunckun, returned the current Bitcoin price and ran sentiment classification over the latest twenty news mentions. Crypto Pulse, on Vercel, scanned public crypto news, classified sentiment, and produced short summaries. Crypto Market News, on Replit, served headline aggregation by ticker. Reviewers noted all three suffered from latency between breaking stories and chat summaries.

DAIZY and Crypto Jobs List

DAIZY, from Daizy Inc, spanned digital assets, US stocks, and US ETFs in a single plugin. For cryptocurrencies, it supplied price, performance, risk, and ESG (environmental, social, and governance) scoring, including carbon footprint and diversity metrics. Crypto Jobs List let users query its database for Web3 roles by keyword, location, and salary.

What were cryptocurrency ChatGPT plugins used for?

Cryptocurrency plugin sessions clustered around five recurring jobs.

• Market data and price queries. CoinMarketCap, CCData, Crypto Prices, CoinCap, and the Polygon (later Massive) plugin let users ask for prices, conversions, and trending tokens without leaving chat. This was the most common workflow.
• DeFi research. DefiLlama and SignalPlus let users compare protocols by TVL, revenue, fees, and category. Quantitative DeFi questions that previously required SQL on Dune or subgraph queries could be asked in plain English.
• On-chain reads. Solana Labs and AlchemyAI exposed RPC-style reads through chat. Users asked for balances, transactions, NFT holdings, and block content directly.
• Security and contract review. GoPlus, Smarter Contracts, and Crypto ERC20 Scout reduced friction for pre-trade due diligence. A user could paste a token contract address and ask whether ownership was renounced or whether the contract had a blacklist function.
• News and sentiment monitoring. Bitcoin Sentiment, Crypto Pulse, and Crypto Market News gave traders a quick read on the news cycle, useful for casual monitoring and idea generation.

How were cryptocurrency plugins built?

A cryptocurrency plugin had three required artifacts: a manifest at /.well-known/ai-plugin.json; an OpenAPI specification listing endpoints, parameters, and response schemas; and a hosted API returning JSON. Authentication options included no auth (used by most price and news plugins), service-level API keys held by the developer, OAuth, and user-supplied API keys typed into the plugin store.

Many plugins shared infrastructure. Several price plugins drew from CoinGecko or CoinCap rather than building independent index aggregation. Crypto ERC20 Scout used CoinGecko for pricing while sourcing token lists from public registries. The Solana Labs plugin combined Solana RPC, the Metaplex Read API, Hyperspace, and HelloMoon. This composability is why a small developer could ship a credible plugin in a weekend over an existing free API.

What were the limitations of crypto ChatGPT plugins?

Crypto plugins inherited several constraints that contributed to OpenAI's decision to wind the program down.

• Discoverability. With the plugin store past one thousand entries by late 2023, users struggled to choose between dozens of overlapping crypto price plugins ^[23]. There was no rating system or traffic analytics.
• Concurrent plugin limit. ChatGPT capped active plugins per conversation at three for most of the beta. Multi-step workflows were possible but awkward.
• Hallucinated calls. The model sometimes invented values for well-known tickers instead of calling the plugin. Alchemy's team explicitly warned users to fact-check responses against block explorers ^[9].
• Latency. Many plugins relied on cached feeds with refresh intervals of minutes to hours. The chat window made the data feel real-time even when it was not.
• Limited monetization. OpenAI did not provide a billing rail, so most crypto plugins were free. This dampened maintenance investment and led to plugins disappearing before the program officially closed.
• Compliance ambiguity. Plugins that returned trading insights, risk scores, or rug pull detection raised questions about whether responses constituted investment advice. Most added disclaimers, but the legal perimeter was never tested in court.

What replaced ChatGPT plugins?

When OpenAI shut down plugins in April 2024, crypto functionality migrated along three tracks. First, many developers, including DefiLlama, GoPlus, and several price plugins, rebuilt their integrations as Custom GPTs in the GPT Store using the actions framework, which mapped one-to-one onto the plugin manifest and OpenAPI patterns. Second, crypto exchanges, wallets, and analytics platforms shifted to direct integrations through the OpenAI API and function calling, gaining control over prompt engineering, retrieval, and compliance logging. Third, several crypto data providers, including CoinGecko, later published Model Context Protocol (MCP) servers, which let any MCP-compatible client call the same data uniformly. The crypto plugin era was short-lived, but it established the design vocabulary for the crypto AI tooling that followed.

ELI5: cryptocurrency ChatGPT plugins

Imagine ChatGPT could only talk about things it had already read, so it did not know today's Bitcoin price. A crypto plugin was like giving ChatGPT a phone it could use to call a crypto data company and ask, "What is Bitcoin worth right now?" or "Is this token safe?" You turned the plugin on, asked your question in normal words, and ChatGPT made the call for you and read back the answer. OpenAI started this in March 2023 and turned it off in April 2024, replacing the plugins with custom chatbots called GPTs.
