Implementation Reference
- src/module.ts:480-502 (handler)The handler function that executes the broadcastTransaction tool logic. It sends the signed transaction (in body) to the Adamik API broadcast endpoint via POST request and returns the JSON response as MCP content.
async ({ chainId, body, }: BroadcastTransactionPathParams & { body: BroadcastTransactionRequestBody; }) => { const result = await makeApiRequest<BroadcastTransactionResponse>( `${ADAMIK_API_BASE_URL}/${chainId}/transaction/broadcast`, ADAMIK_API_KEY, "POST", JSON.stringify(body) ); const text = JSON.stringify(result); return { content: [ { type: "text", text, }, ], }; } - src/schemas.ts:607-627 (schema)Zod schema definitions for the broadcastTransaction tool, including path parameters (chainId), request body structure (transaction data from encode, encoded items, signature), and response (chainId, optional hash).
export const BroadcastTransactionPathParamsSchema = z.object({ chainId: ChainIdSchema, }); export type BroadcastTransactionPathParams = z.infer<typeof BroadcastTransactionPathParamsSchema>; export const BroadcastTransactionRequestBodyTransactionSchema = z.object({ data: EncodeTransactionResponseDataSchema, // Data from encode response encoded: z.array(EncodedItemSchema), // Encoded from encode response signature: z.string(), }); export const BroadcastTransactionRequestBodySchema = z.object({ transaction: BroadcastTransactionRequestBodyTransactionSchema, }); export type BroadcastTransactionRequestBody = z.infer<typeof BroadcastTransactionRequestBodySchema>; export const BroadcastTransactionResponseSchema = z.object({ chainId: ChainIdSchema, hash: z.string().optional(), }); export type BroadcastTransactionResponse = z.infer<typeof BroadcastTransactionResponseSchema>; - src/module.ts:470-479 (registration)MCP server tool registration for 'broadcastTransaction', providing the tool name, description, and input schema (chainId and body using imported schemas).
