Teardrop crypto research agent over A2A: ask in plain language about token prices, DeFi yields and lending, wallet portfolios, approvals and counterparty risk, or onchain transactions; the agent plans and runs Teardrop's onchain data tools and returns a completed task. Pay per task with x402 USDC on Base.

Teardrop assess_counterparty_risk: Return a decision-ready counterparty-risk verdict for an EVM address before funds or authority are committed. The result branches to high_risk, caution, acceptable, or insufficient_data with the evidence needed for the calling agent to act.

Teardrop assess_market_resolution: Return a decision-ready resolution-risk verdict for one Polymarket market before an agent trades, quotes, or forecasts it. The result branches to tradeable, ambiguous, avoid, or insufficient_data and names the resolution basis (price_feed, official_source, media_consensus, unspecified), UMA dispute state, rule-wording risks, and executability (liquidity, spread) so the calling agent can act without reading the full rules.

Teardrop convert_currency: Convert an amount between fiat currencies (USD, EUR, GBP) and crypto assets (BTC, ETH, USDC, SOL) and return the converted amount plus the exchange rate used.

Teardrop decode_transaction: Decode a transaction's calldata into a human-readable function name and arguments, and return transaction status (1=success, 0=revert), gas used, and block number. Uses a supplied ABI when provided, otherwise 4byte.directory. Supports Ethereum mainnet and Base.

Teardrop get_block: Get block details (timestamp, gas used, base fee, miner, transaction count) for an Ethereum or Base block by number, hash, or 'latest'. Use to anchor events to a point in chain time.

Teardrop get_chain_metrics: Compare blockchain ecosystem health via DeFiLlama: current TVL, 7/30-day TVL change, and aggregate fee activity. Pass chains such as ['Ethereum', 'Arbitrum', 'Solana'] for a focused comparison, or omit chains to inspect the highest-TVL ecosystems.

Teardrop get_defi_positions: Block-accurate DeFi positions for a wallet across Aave v3, Compound v3, Uniswap v3 LP, and Lido on Ethereum or Base. Returns Aave account health (collateral, debt, health factor, LTV) with per-reserve breakdown, Compound v3 market positions, Uniswap v3 LP positions by token ID, and on Ethereum the Lido stETH/wstETH balances with the current wstETH-to-stETH equivalent. Per-protocol failures are isolated - other protocols still return.

Teardrop get_dex_quote: Get the best Uniswap v3 swap quote on Ethereum (chain_id=1) or Base (chain_id=8453) via direct on-chain QuoterV2 calls. Queries all four fee tiers (100/500/3000/10000 bps) in parallel and returns the tier with the highest output amount, along with per-tier breakdown. Inputs are raw uint256 amounts and EIP-55 checksummed addresses; native ETH is not quoted directly - pass the WETH address. Returns no_liquidity=true when no pool exists for the pair. Point-in-time quote a...

Teardrop get_dex_volume: Compare decentralized exchange activity via DeFiLlama: 24h/7d/30-day volume, period-over-period changes, and each protocol's share of reported global 24-hour DEX volume. Filter by protocol and rank by a 1-, 7-, or 30-day lookback window.

Teardrop get_erc20_balance: Get the exact on-chain ERC-20 balance of a wallet for one token contract, normalized by decimals and returned with the token's symbol. Use for a precise single-token check.

Teardrop get_eth_balance: Get the exact on-chain native ETH balance of an address on Ethereum or Base, in wei and ether. get_wallet_portfolio already includes native ETH in its holdings - call this only for a standalone balance without a portfolio scan.

Teardrop get_gas_price: Get current EIP-1559 gas fees on Ethereum or Base: base fee, priority fee, next-block base fee estimate, and congestion (gas_used_ratio >0.5 busy, >0.9 very congested). Optional USD estimates cover a simple transfer and a swap-like transaction. Cached 10 seconds per chain.

Teardrop get_lending_rates: Get current on-chain lending supply/borrow APYs for Aave v3 reserves and Compound v3 markets on Ethereum or Base, with per-asset snapshots and Compound utilization. Use for protocol-specific yield comparisons such as USDC on Aave vs Compound.

Teardrop get_liquidation_risk: Assess DeFi liquidation risk for up to 50 wallets across Aave v3 and Compound v3 on Ethereum or Base. Returns per-wallet health factor, tiered risk classification (liquidatable, critical, warning, caution, healthy, no_debt), and an overall_tier aggregate. Per-protocol failures are isolated - one protocol's RPC error does not blank the other's result.

Teardrop get_token_approvals: Block-accurate audit of ERC-20 allowances for a wallet across curated DeFi spenders (Uniswap, Aave, Compound, 1inch, 0x, OpenSea) on Ethereum or Base. Flags unlimited approvals by risk level (high=unknown spender, medium=trusted protocol, low=bounded). Use before swaps or after security incidents to detect active exploit vectors.

Teardrop get_token_price: Get current price, 24h change, market cap, FDV, and volume for one or more crypto tokens. Accepts ticker symbols, full names, or CoinGecko IDs; unknown symbols resolve automatically. Batch up to 50 tokens. Reuse price_usd/value_usd already returned by get_wallet_portfolio instead of re-calling.

Teardrop get_token_price_historical: Get historical crypto prices over a 1-365 day window: period statistics (start, end, % change, high, low), a downsampled daily series, high_30d, std_30d, and dca_baseline_90d. Use for period comparisons and trend analysis; prefer over web_search for time-comparative financial queries. Pass stats_only=true when the daily series is unnecessary.

Teardrop get_transaction: Get details and receipt for one Ethereum or Base transaction by hash: bounded calldata, normalized event logs, transaction index, and receipt-derived effective gas price and fee when available. Use to verify a specific transaction's status and outcome.

Teardrop get_wallet_approvals: Inspect a wallet's current ERC-20 token authorization exposure on one DeBank-supported chain. Returns discovered spenders, USD exposure, protocol attribution, and hacked or abandoned protocol flags. This is broader than the curated block-accurate get_token_approvals tool.

Teardrop get_wallet_history: Get one page of decoded transaction history for an EVM wallet across DeBank-supported chains. Returns send, receive, and approval categories with protocol, token, exchange, gas, and USD metadata. Use the returned next_cursor as start_time to page backward.

Teardrop get_wallet_portfolio: Get aggregated token holdings with USD values for a wallet address. Tracks 19 major assets on Ethereum and 12 on Base, including spot, lending, liquid-staking, restaking, and stablecoin assets. Sorted by USD value. Returns up to 20 holdings. Includes native ETH balance in the holdings list - calling get_eth_balance separately after this is redundant.

Teardrop get_wallet_positions: Get a wallet's DeFi positions across all DeBank-supported chains and protocols. Returns protocol-level positions, asset/debt/net USD values, optional token lists, aggregate exposure, and optional all-chain net worth. Set include_token_balances=true to also return DeBank's complete cross-chain wallet token list. Set include_token_lists=false for a compact balance and debt summary without nested position tokens. This covers substantially more protocols and chains...

Teardrop get_yield_rates: Get DeFi yield pool rates from DeFiLlama across 1,000+ protocols and all chains: pools sorted by APY with TVL, base/reward APY, and 7d/30d mean APY context, filterable by protocol, chain, min TVL, min/max APY, and symbol. Returns up to 50 pools. For protocol-specific lending comparisons (Aave vs Compound) prefer get_lending_rates.

Teardrop http_fetch: Fetch a web page and return its main text content, cleaned of markup. Use to read articles, documentation, and other resources referenced by URL. Blocks private and cloud-metadata addresses and re-validates every redirect hop.

Teardrop read_contract: Call any view/pure function on a smart contract and return the decoded result, using a supplied ABI fragment. Supports historical reads via block_identifier and caller_address context for msg.sender-dependent views. Read-only: state-changing functions are rejected.

Teardrop resolve_ens: Resolve an ENS name (e.g. 'vitalik.eth') to an Ethereum address, or an address to its primary ENS name, with avatar text record when available. Mainnet only.

Teardrop validate_opportunity: Return a decision-ready yield-opportunity verdict before capital is deployed. The result branches to sustainable, caution, unsustainable, or insufficient_data and gives the calling agent the evidence needed to proceed, pause, or reject the opportunity.

Teardrop web_search: Real-time web search via Tavily for current events, fact-checking, and research. Use search_depth='advanced' for complex queries (higher quality, higher cost) and topic='news' or 'finance' for headlines or market information.
