--- name: bridge.eruditepay.com description: bridge.eruditepay.com provides read-only data endpoints for cross-chain bridging infrastructure, covering route discovery, gas price feeds, DEX swap quotes, liquidity pool analytics, block-level transaction data, and TRON-specific DeFi metrics. It does not execute transactions or swaps. Skills span EVM chains (Ethereum, Optimism, Base, Polygon, Arbitrum) and TRON. host: bridge.eruditepay.com --- # bridge.eruditepay.com EruditePay Bridge is a data and intelligence layer for cross-chain activity. It serves agents that need to research, plan, or audit bridge and swap operations before or after execution — not agents that need to execute them. Its skill set is split between EVM-focused infrastructure (gas, routes, quotes, block data) and TRON-specific DeFi data (TVL, address counterparties), making it useful for multi-chain dashboards, pre-trade checks, and on-chain auditing workflows. ## When to use this host Use bridge.eruditepay.com when an agent needs to research or audit cross-chain activity: discovering available bridge routes, checking gas costs across EVM chains, getting DEX swap quotes, analyzing pool efficiency, inspecting block transactions, or retrieving TRON DeFi data. Do not use this host to execute any swap, bridge transfer, or payment — it is strictly read-only. For gas price forecasting (next 24 hours), the host itself points to a separate /v1/intel/gas/forecast endpoint not covered here. For non-EVM chain gas or routing data beyond TRON, this host is not suitable. For CEX pricing or off-chain quotes, use a dedicated CEX data provider instead. The TRON skills are chain-specific and should not be used as proxies for EVM address or TVL lookups. ## Capabilities ### Bridge Route Discovery Identifies which cross-chain token transfer paths are available, including fees and transfer limits, before any transaction is initiated. - **`fetch-supported-bridge-routes`** — Returns all supported cross-chain bridging routes and token pairs available via EruditePay, including fees and transfer limits. ### Pre-Trade Pricing and Gas Provides real-time DEX swap quotes and current gas price estimates across EVM chains, enabling cost-aware trade planning and chain selection. - **`fetch-dex-swap-quote`** — Returns a real-time DEX swap quote for a token trade across supported chains and bridges via the EruditePay bridge API. - **`fetch-gas-prices`** — Returns real-time gas price estimates in gwei and USD for simple transactions across Optimism, Polygon, Base, Arbitrum, and Ethereum. ### Liquidity Pool Analytics Assesses trading efficiency of liquidity pools by returning volume-to-TVL ratios over configurable timeframes. - **`fetch-pool-volume-tvl-ratio`** — Returns the volume-to-TVL ratio for a liquidity pool over a specified timeframe, indicating how actively the pool is being traded relative to its locked liquidity. ### Block and Transaction Data Retrieves confirmed transactions within a specific blockchain block for auditing, exploration, or historical analysis. - **`fetch-block-transactions`** — Returns the list of transactions included in a specified blockchain block via the EruditePay Bridge API. ### TRON DeFi Intelligence Covers TRON-specific data including chain-level aggregate DeFi TVL and payment schema details for individual TRON addresses. - **`fetch-tron-defi-tvl`** — Returns the current Total Value Locked (TVL) for DeFi protocols on the TRON blockchain, sourced from DefiLlama. - **`fetch-tron-address-counterparties`** — Retrieves counterparties and accepted payment schemas for a given TRON address, including assets, payTo, amount, network, and timeout details. ### Base Resource Search Queries the EruditePay Bridge base index to filter and retrieve structured data records by query parameters. - **`search-eruditepay-bridge-base`** — Queries the EruditePay Bridge v1 base search endpoint to retrieve indexed and filtered base resources. ## Workflows ### Cross-Chain Bridge Pre-Flight Check *Use when an agent needs to validate that a desired cross-chain transfer is feasible and cost-effective before committing to execution.* 1. **`fetch-supported-bridge-routes`** — Confirm that the desired source chain, destination chain, and token pair are supported and retrieve applicable fees and limits. 2. **`fetch-gas-prices`** — Check current gas prices on the source chain to estimate total transaction cost and determine whether cost thresholds are met. 3. **`fetch-dex-swap-quote`** — Obtain a real-time swap quote for the token pair to assess slippage and output amount before proceeding. ### Liquidity Pool Opportunity Assessment *Use when an agent needs to evaluate whether a liquidity pool on a supported chain is actively traded and worth interacting with.* 1. **`fetch-gas-prices`** — Retrieve current gas costs on the relevant chain to factor transaction overhead into the pool assessment. 2. **`fetch-pool-volume-tvl-ratio`** — Fetch the volume-to-TVL ratio for the target pool to gauge trading activity efficiency relative to locked liquidity. ### TRON Address Payment Readiness Check *Use when an agent needs to understand what payment schemas a TRON address accepts and contextualize that within the broader TRON DeFi ecosystem.* 1. **`fetch-tron-defi-tvl`** — Retrieve aggregate TRON DeFi TVL to establish ecosystem context and liquidity depth. 2. **`fetch-tron-address-counterparties`** — Look up the specific TRON address to identify accepted assets, networks, amounts, and timeout parameters for payment planning. ## Skill reference ### `fetch-supported-bridge-routes` **EruditePay Bridge Supported Routes** — Returns all supported cross-chain bridging routes and token pairs available via EruditePay, including fees and transfer limits. *Use when:* Use when an agent needs to discover which source/destination chain and token combinations are available for cross-chain transfers before initiating a bridge transaction. *Not for:* Do not use to execute a bridge transfer or get a live quote for a specific amount; use a bridge execution or quote endpoint instead. **Returns:** Returns a routes array listing each supported chain-to-chain token pair with fee percentage and min/max transfer limits, plus a _meta object with provider info and response timing. **Example:** `GET https://bridge.eruditepay.com/v1/bridge/supported-routes` --- ### `fetch-gas-prices` **Erudite Gas Prices** — Returns real-time gas price estimates in gwei and USD for simple transactions across Optimism, Polygon, Base, Arbitrum, and Ethereum. *Use when:* Use when an agent needs current gas prices across multiple EVM chains to estimate transaction fees, select the cheapest chain, or gate a transaction on cost thresholds. *Not for:* Do not use for gas price forecasting over the next 24 hours;
