--- name: silverback-x402.onrender.com description: silverback-x402.onrender.com provides five DeFi intelligence skills covering token security auditing, liquidity pool analysis, technical analysis, yield opportunity discovery, and cross-DEX arbitrage scanning on Base. All skills return single-shot analytical snapshots; none execute trades, stream live prices, or manage wallets. The host is oriented toward pre-trade research and risk assessment workflows. host: silverback-x402.onrender.com --- # silverback-x402.onrender.com This host serves agents that need structured DeFi research data before committing to a trade, investment, or yield strategy. It covers the core due-diligence surface: is the token safe (audit), is the pool healthy (liquidity), is the price action favorable (TA), where can yield be maximized (yield), and is there an arbitrage edge (arb scanner). All five skills are read-only analytical endpoints scoped to EVM chains, with the arbitrage and pool skills explicitly limited to Base. ## When to use this host Use this host when an agent needs read-only DeFi research across token safety, pool health, technical signals, yield ranking, or Base arbitrage detection. It is well-suited for pre-trade due diligence pipelines that chain audit → pool → TA checks. Do not use it for: live or streaming price feeds (use a dedicated price oracle or DEX quote API), swap or trade execution (use a DEX aggregator with routing), cross-chain arbitrage outside Base (the arb scanner is Base-only), auditing NFT contracts or general DeFi protocol contracts (the security audit covers tokens only), or analysis of assets not listed on CoinGecko (the TA skill requires a CoinGecko token ID). All five skills are single-shot endpoints with no stateful session or order management. ## Capabilities ### Token Safety & Risk Assessment Establishes whether a token contract is safe to interact with by detecting honeypots, minting risks, ownership status, and liquidity lock state before any capital is deployed. - **`audit-token-security`** — Performs a comprehensive security audit on an EVM or Solana token contract, returning honeypot detection, tax analysis, ownership risks, and a numeric risk score. ### Liquidity & Pool Health Evaluates the health, activity, and depth of a specific AMM liquidity pool on Base, surfacing TVL, fee tier, volume, and buy/sell ratio to inform swap or LP decisions. - **`analyze-liquidity-pool`** — Returns TVL, liquidity rating, health score, fee, 24h volume, trading activity, and token reserves for an AMM liquidity pool on Base. ### Price Action & Technical Analysis Delivers a full technical readout — RSI, EMA, MACD, Bollinger Bands, support/resistance, chart patterns, and a directional recommendation — for a CoinGecko-listed asset over a chosen timeframe. - **`fetch-technical-analysis`** — Returns RSI, EMA, MACD, Bollinger Bands, support/resistance levels, chart patterns, and a directional trading recommendation for a given CoinGecko token over a specified timeframe. ### Yield Intelligence Ranks DeFi yield opportunities for a given token across protocols, providing APR breakdowns, risk scores, impermanent loss estimates, and an optimal allocation strategy split filtered by risk tolerance. - **`fetch-defi-yield-opportunities`** — Returns ranked DeFi yield opportunities for a given token with APR breakdowns, risk scores, impermanent loss estimates, and an optimal portfolio allocation strategy. ### Arbitrage Detection Scans multiple DEXes on Base for price discrepancies between two tokens, returning quotes, spreads, and gas estimates to determine whether a profitable arbitrage opportunity exists. - **`scan-cross-dex-arbitrage`** — Scans DEXes on Base for arbitrage opportunities between two tokens, returning quotes, spreads, and gas estimates for a given input amount. ## Workflows ### Pre-Trade Token Due Diligence *Use when an agent needs to fully vet a token before recommending or executing a trade — covering contract safety, pool health, and price action in sequence.* 1. **`audit-token-security`** — Check the token contract for honeypot flags, minting risks, and ownership renouncement to confirm it is safe to trade. 2. **`analyze-liquidity-pool`** — Assess the target pool's TVL, health score, and buy/sell ratio to confirm sufficient liquidity and acceptable LP risk. 3. **`fetch-technical-analysis`** — Retrieve RSI, EMA, MACD, and support/resistance levels to determine whether the current price action supports the intended trade direction. ### Yield Opportunity Vetting *Use when an agent needs to identify and validate a DeFi yield position — first confirming the token is safe, then surfacing the best yield options.* 1. **`audit-token-security`** — Audit the token contract to rule out honeypot or ownership risks before committing capital to a yield strategy. 2. **`fetch-defi-yield-opportunities`** — Retrieve ranked yield opportunities with APR breakdowns and an optimal allocation strategy for the vetted token. ### Arbitrage Opportunity Validation *Use when an agent needs to confirm a Base arbitrage opportunity is viable — verifying token safety and pool depth before acting on a detected spread.* 1. **`audit-token-security`** — Confirm the token contracts involved are not honeypots or otherwise unsafe before pursuing the arbitrage. 2. **`analyze-liquidity-pool`** — Verify the relevant pool has sufficient TVL and volume to absorb the arbitrage trade without excessive slippage. 3. **`scan-cross-dex-arbitrage`** — Scan Base DEXes for the token pair to confirm a profitable spread exists given the validated pool conditions. ## Skill reference ### `fetch-defi-yield-opportunities` **YieldPulse DeFi Yield Opportunities** — Returns ranked DeFi yield opportunities for a given token with APR breakdowns, risk scores, impermanent loss estimates, and an optimal portfolio allocation strategy. *Use when:* Use when an agent needs current DeFi yield rates and protocol-level allocation recommendations for a specific token (e.g. USDC, WETH, SOL) filtered by risk tolerance, including top opportunities and an optimal strategy split. *Not for:* Do not use for real-time price feeds or token swap execution; this endpoint returns yield intelligence only, not trade routing or live market prices. **Inputs:** - `token` (string) — Token symbol (USDC, WETH, SOL) or contract address to find yield opportunities for. - `riskTolerance` (string) — Risk level filter for returned opportunities. Accepted values: low, medium, high.
