Enterprise ABI Management

Smart Contract Interface Standardization

The Application Binary Interface (ABI) serves as the critical bridge between enterprise applications and blockchain smart contracts. This standardized interface specification enables seamless interaction between human-readable Solidity contracts and the Ethereum Virtual Machine, defining function signatures, parameters, and return types for enterprise integration.

ABI Enterprise Benefits

Type-safe integrations prevent runtime errors
Auto-generated documentation reduces learning curves
Universal compatibility across EVM-compatible chains
Version control for enterprise governance

Production Deployment

Automated ABI extraction from deployment artifacts

ABI Deployment Process

Extract ABI from Deployment

Locate your ABI files in the deployment artifacts after contract deployment. Reference the Smart Contract Deployment Guide for detailed extraction procedures.

Configure Portal Middleware

Upload at least one ABI file when creating new middleware to enable API generation and type-safe interactions.

Update Production ABIs

For existing portals, navigate to the middleware details and select 'Manage Middleware' → 'Update ABIs' to upload new or modified ABI files for hot deployment.

import { Webhook } from "standardwebhooks";

async function webhookConsumerBootstrap(secret: string) {
  const webhookConsumer = new Elysia().post(
    "/scp-listener",
    ({ headers, body }) => {
      try {
        const wh = new Webhook(btoa(secret));
        const verifiedPayload = wh.verify(JSON.stringify(body.payload), {
          "webhook-id": headers["btp-portal-event-id"]!,
          "webhook-signature": headers["btp-portal-event-signature"]!,
          "webhook-timestamp": headers["btp-portal-event-timestamp"]!,
        });
        console.log(
          `Received a webhook event: ${JSON.stringify(verifiedPayload)}`
        );
      } catch (err) {
        console.error("Webhook payload invalid", err);
        throw err;
      }
    },
    {
      body: t.Object({
        payload: t.Object({
          apiVersion: t.String(),
          eventId: t.String(),
          eventName: t.String(),
          timestamp: t.Number(),
          data: t.Any(),
        }),
      }),
    }
  );
  const app = new Elysia().use(webhookConsumer).onStart(({ server }) => {
    console.log(
      `Started the test webhook consumer on ${server?.url.toString()}`
    );
  });
