| network | No | Network type (defaults to mainnet) |
Implementation Reference
- Core handler function that fetches the current gas price using the blockchain RPC eth_gasPrice method, handles EVM-compatible chains, converts values to Gwei and Wei, and returns formatted response.
async getGasPrice( blockchain: string, network: 'mainnet' | 'testnet' = 'mainnet' ): Promise<EndpointResponse> { const service = this.blockchainService.getServiceByBlockchain(blockchain, network); if (!service) { return { success: false, error: `Blockchain service not found: ${blockchain} (${network})`, }; } const result = await this.blockchainService.callRPCMethod( service.id, 'eth_gasPrice', [] ); if (result.success && result.data) { const gasWei = BigInt(result.data); const gasGwei = Number(gasWei) / 1e9; return { success: true, data: { gasPrice: gasGwei, gasPriceWei: gasWei.toString(), gasPriceHex: result.data, }, metadata: result.metadata, }; } return result; } - src/handlers/multichain-handlers.ts:65-83 (registration)Tool registration definition including name, description, and input schema for the MCP server.
