Did you know? “Events” on Solidity are how smart contracts communicate to the outside world on BSC.
Here’s a quick refresher guide on Solidity events and logs:
1️⃣ ERC-20 style example
event Transfer(address indexed from, address indexed to, uint256 value);
2️⃣ Best practice is to emit events whenever state changes, for example:
emit ValueChanged(oldValue, newValue);
Why events matter on BSC:
🔸 Power BscScan & opBNBScan token tracking
🔸 Enable fast off-chain indexing & analytics
🔸 Cheaper than reading contract storage
Note: Events are off-chain only. Other contracts can’t read them.
If your dApp looks quiet on explorers, check your events to make sure they follow the best practices.

What x402 actually does
Explained in very simple terms:
x402 brings payments directly into HTTP.
Meaning:
A website, API, or agent can say:
“This costs $0.01 USDC. Pay to continue.”
Your browser or AI agent pays instantly.
Just: request → pay → receive.
Money moves like a web request.
Internet + native payments.
It’s not a new blockchain.
Just using the rails we already use every day: HTTP.
And behind it, there’s one person you should know:
Erik Reppel.
Who he is:
• Canadian, ~29
• Grew up in Port Moody, British Columbia
• Studied Software Engineering at the University of Victoria
• Won Hack The North, the biggest hackathon in Canada
• Moved to San Francisco
• Spent years building ML systems inside Coinbase
• Built the data + infrastructure layer at Zora
• Briefly worked at Clubhouse during its peak
• Returned to Coinbase in 2025 as Head of Engineering for the Developer Platform
The internet is going from humans clicking pages to agents doing tasks for us:
• Research agents
• Shopping agents
• Data-fetching bots
• AI assistants that call APIs
• Autonomous workflows talking to each other
These agents need to pay for things:
• Data
• Compute
• Storage
• Tools
• Premium endpoints
• Other agents
But agents cannot:
• Enter credit card details
• Create accounts
• Pass KYC
• Confirm payments manually
They need to pay programmatically.
Instantly.
Safely.
Without friction.
x402 is exactly for this moment.
Who already integrated it
• Cloudflare → integrated into their global network (78M+ requests/sec)
• Google → if Google agents call an API, they can settle with USDC on Base/Solana
• Visa → x402 used for settlement
Real usage (not theory)
Right now it’s already being used for:
• Paying $0.01 to fetch Farcaster data through Neynar
• Paying per scrape request on Firecrawl
• Storing and retrieving media on Pinata with no account
• AI agents buying compute in small increments
• Content unlocks directly in the browser
• Micro-APIs that charge fractions of a cent
How Erik thinks:
“Value should move across the internet as easily as information.”
He believes:
• The future internet is machine-native
• Agents will transact with each other
• Subscriptions are inefficient
• Static pricing breaks when machines negotiate
• Web needs a stable, neutral, open payment standard
Maybe we’re seeing the beginning of a new era in crypto:
AI Agents that can pay.
What do you think?

@ZoeJardiniere Always admire how well you speak on these shows in the face of literally the worst people

I get so many ridiculous dumb emails for products that you guys never hear about, but I couldn't resist sharing this one: a THREE HUNDRED DOLLAR water bottle that promises to add hydrogen to your water and track your usage 🤦🏾♂️
Maybe it's almost time for another "saying yes to everything" video 😭
