Crypto Plugins

18 of the 47 plugins are crypto-specific. All are read-only — OpenVesper does not bundle trading execution, key management, or signing code by default — you can add them in your own plugins if you need them. We orchestrate, analyze, and research. We don't move funds.

Privacy and security commitments

No plugin in this repository reads a main wallet private key or seed phrase.
No bundled agent persona requests a seed phrase. (What you author yourself is your call.)
No example, doc, or tutorial in this repository instructs pasting a main wallet key into .env.
Trading on perpetual DEXes (Hyperliquid, Lighter, Drift) is not bundled. Use those venues' official clients separately — or write your own plugin if you want an agent to drive them.

See Security policy for the full Wallet Key Policy and how this is enforced in code.

The 18 crypto plugins

Market data (read-only)

Plugin	Source	Capabilities
`crypto`	CoinGecko, Binance	Spot prices, technical indicators, OHLC
`derivatives`	Coinglass, Binance	Fear & Greed, OI, L/S ratio, liquidations, volatility
`defi`	DefiLlama	TVL, protocol details, yield, chain stats
`whale`	Etherscan, Helius	Large transfer detection, exchange flows
`onchain`	Block explorers	Transaction lookup, contract reads, ABI decoding

Solana ecosystem

Plugin	Source	Capabilities
`solana`	Helius, public RPCs	Account info, SPL balances, token metadata
`solana-dev`	Anchor IDL, Token-2022	Anchor program decode, cNFT lookup, account parsing
`bagsfm`	Bags.fm public API	Token analytics, holder distribution
`memescan`	GeckoTerminal, Birdeye	Trending pairs, multi-DEX scan, signal scoring
`base-meme`	BaseScan, GeckoTerminal	Base chain memecoin scanning

Research & alerts

Plugin	Source	Capabilities
`airdrop`	Public airdrop trackers	Active campaign list, eligibility checks
`nft`	OpenSea, Magic Eden	Floor prices, collection stats, recent sales
`security`	GoPlus, Etherscan	Token honeypot check, contract verification status
`macro`	RSS, public APIs	Macro news, economic calendar, central bank updates

Strategy & analytics

Plugin	Source	Capabilities
`strategies`	Local computation	Backtest scaffolds, Pine Script generation, signal logic
`tracking`	Public APIs	Portfolio tracking from public addresses
`banking`	Plaid (BYO)	Fiat balance read (requires Plaid key)

Example: scanning Solana meme coins

# Find trending Solana memes with strong buy pressure
node apps/cli/dist/index.js agent --message \
  "Scan top 20 trending Solana memes on GeckoTerminal,
   filter by liquidity > $50k, sort by buy pressure"

The runtime routes this to the memescan plugin which calls GeckoTerminal's public API, filters, scores, and returns the results.

Example: reading a Solana account

# Get the SPL token holdings for a wallet
node apps/cli/dist/index.js agent --message \
  "What SPL tokens does 9WzD...A4d hold? Use Helius RPC."

Routes to plugin-solana → calls getTokenAccountsByOwner via the public Helius RPC → returns token balances with metadata.

API keys needed

Most plugins work with free public APIs. A few benefit from keys for higher rate limits:

# Optional — improve rate limits
HELIUS_API_KEY=               # Solana, free tier OK
BIRDEYE_API_KEY=              # Solana market data
COINGECKO_API_KEY=            # Price data
ETHERSCAN_API_KEY=            # Ethereum explorer
BASESCAN_API_KEY=             # Base explorer
ARBISCAN_API_KEY=             # Arbitrum explorer

What's NOT included

By design, these are not in the framework:

Perpetual DEX trading (Hyperliquid, Lighter, Drift)
Wallet creation or seed phrase handling
Transaction signing (we never see your keys)
Auto-trading or order placement on any venue
Withdrawals or fund movement of any kind

If you want to add these capabilities, write your own plugin in your own fork. Keep signing code in a separate, carefully audited process with stricter security boundaries.
