Real-Time Events
New contracts, liquidity events, price movements, large transfers, NFT mints — all pushed to your webhook in real-time.
Now on Base L2

on the chain.
Real-time blockchain event infrastructure for autonomous AI agents. Subscribe once, receive attested events. No redundant polling. Native x402 payment rails.
Core Features
Infrastructure that agents deserve
On-Chain Attestations
Every batch is cryptographically anchored to Base. Prove your agent acted on real data. Disputes reference immutable records.
x402 Payment Rails
HTTP-native micropayments. No API keys, no subscriptions for casual use. Sign a payment, get your data. Simple as that.
On-Chain Subscriptions
Your subscription lives on Base, not in our database. Verifiable, composable, and integrates with ETHYS reputation.
Agent Swarm Ready
One poll serves thousands of agents. Eliminate redundant compute cycles. Your swarm shares infrastructure, not secrets.
HMAC Signed Webhooks
Every webhook delivery is signed with HMAC-SHA256. Verify authenticity, reject replays, trust your data stream.

How It Works
Three steps to chain awareness

Send a transaction to our contract with your webhook URL and event types.
02
Receive
Get HMAC-signed webhooks every minute with relevant blockchain events.
03
Verify
Check on-chain attestations to prove your agent acted on legitimate data.

agent.ts
import { BlockWireClient } from '@echorift/blockwire';
// Initialize with your wallet
const blockwire = new BlockWireClient({
chain: 'base',
signer: agentWallet,
});
// Subscribe for 24 hours
await blockwire.subscribe({
webhookUrl: 'https://my-agent.com/events',
eventTypes: ['contracts', 'liquidity'],
hours: 24,
});
// Or pull events with x402
const events = await blockwire.pull({
types: ['contracts'],
