Transaction Simulation And Gas Estimation With Revert Reason Extraction

Give your AI agent a wallet. AgentFi provides 10 MCP tools for executing DeFi transactions on EVM chains (Ethereum, Base, Arbitrum, Polygon). Swap tokens, transfer assets, supply to Aave, check balances and prices — all policy-constrained and simulated before broadcast. Each agent gets a dedicated S

Unique: Combines eth_call simulation with revert reason extraction via error message parsing and ABI decoding, providing agents with detailed failure diagnostics. Most simulation libraries return only success/failure; AgentFi extracts actionable error messages.

vs others: More informative than raw eth_call results because it decodes revert reasons, while faster than full transaction execution because it uses read-only simulation.

MCP server for using Alchemy APIs

Unique: Exposes Alchemy's transaction simulation APIs as MCP tools, enabling agents to validate and debug transactions before broadcasting, with detailed execution traces that inform decision-making without requiring custom simulation infrastructure

vs others: Provides pre-execution validation through Alchemy's infrastructure compared to agents blindly broadcasting transactions or using generic eth_call without detailed trace information, reducing failed transaction costs
