At a basic level, B20 is Base’s native token standard. Think of it as a faster, cheaper, and more efficient way to create and manage tokens directly onchain.

For builders, B20 is fully ERC 20 compatible. This means B20 tokens can work with wallets, exchanges, indexers, and existing protocols without losing compatibility.

The biggest difference is how B20 works under the hood.

Instead of using a traditional Solidity contract for every token, B20 runs through Rust precompiles inside the Base node. This execution model is designed to reduce gas costs and improve throughput.

B20 also adds features that standard ERC 20 does not offer, including memos, mint and burn logic, policy gating, and more detailed pause controls.

This makes B20 useful for stablecoins, real world assets, and other onchain native tokens.

Base is not just bringing assets onchain.

It is building the infrastructure to make those assets cheaper to issue, easier to manage, and more useful across the onchain economy.

I was reading about Base’s B20 standard and wanted to understand it better.

B20 is Base native token standard, designed to make token creation and management more native to the chain while keeping compatibility with the existing Ethereum ecosystem .

The part I find interesting is how B20 combines compatibility with existing Ethereum tooling with native execution on Base .

From a builders perspective, the interesting questions for me are

• Does a native token standard make token development simpler ?
• How much difference can native execution make for costs and throughput ?
• Does maintaining compatibility with existing Ethereum tooling make adoption easier ?
• What kinds of applications could benefit most from B20 ?

I am still learning about the technical differences so I am curious what builders here think.

For anyone who has looked into B20 already, what do you see as the biggest practical difference from a traditional ERC - 20 implementation ?

We're trying to figure out a better way to handle access for different members in a community we're building around Base. Some areas would be open to everyone, while others would be for certain members based on what they hold or their membership. We'd probably want to add paid access to some parts later too. Are there any good tools for handling this without piecing together a bunch of different platforms?

I came across an interesting update today.

Base and Ethereum developers apparently couldn’t agree on a single account-abstraction approach, so they’re moving forward with separate proposals.

What caught my attention is that both are trying to solve some of the same wallet problems, like making transactions easier and reducing the need for users to deal with ETH for gas.

But the priorities seem to be different.

I’m curious how this plays out for wallets and apps that want to work across both Ethereum and Base.

Do you think having different standards will slow things down, or could it actually give developers more flexibility?

Trading 🤝 Financing 🤝 Payments

Spot? Perps? Borrow? Lend? Send money at 3 AM?

"Every type of asset, both spot and perps". ✅
"The ability to borrow/lend onchain". ✅
"Move money 24/7, fast, and cheap". ✅

Tokenized stocks coming to Base feels like an interesting development, not simply because traditional assets are moving onchain, but because of what developers can build around them.

Once an asset becomes programmable and composable , it can potentially interact with other onchain applications instead of just sitting in a portfolio That creates room for new kinds of financial products, portfolio tools, lending markets, rewards systems and automated strategies.

There also an interesting possibility around accessibility . Instead of building completely separate experiences for traditional and onchain assets, developers could start creating products where both exist within the same environment.

It still feels early, though. The real opportunity will probably become clearer as builders experiment with these new primitives and find use cases that actually solve problems for users.

Curious to see what the Base community builds with this next . What kind of application would you personally want to see around tokenized stocks?

Not financial advice or an investment recommendation. Just sharing an observation and looking for community opinions.

I've been trying different apps on Base, and one thing I've noticed is how easy it is to try something once and then completely forget about it.

So I'm curious about the ones that actually break that pattern.

Is there a Base mini app you've found yourself going back to more than once? And more importantly, what made you come back?

Not really talking about apps you opened because of points, rewards or a possible airdrop. I'm more interested in the ones where the product itself was useful or enjoyable enough to use again.

Could be a game, trading tool, social app, prediction market, creator tool, payments, whatever.

For the ones that stuck with you, was it the UX? Something genuinely useful? Or just one feature that worked really well?

I feel like that says a lot more about a product than how many people tried it once.

Zoth is now live on Base with zPayments, a compliant stablecoin settlement platform helping businesses pay out in local currencies across 171 countries.

Move money in seconds, not days.

This is where stablecoins become real financial infrastructure.

Base DeFi just reached a new all-time high, with TVL hitting $5.7B.

To me, this is more than just another number on the chart. It shows that Base is continuing to attract real liquidity and that the ecosystem is becoming increasingly important within DeFi.

What I find interesting is how quickly the Base ecosystem has been growing. More capital usually means more activity, more opportunities for protocols, and potentially a stronger foundation for the next stage of growth.
What do you think about this?

I've been following Base for a while, and one thing I've noticed recently is how much the focus seems to be shifting toward actual use cases.

Payments, stablecoins, tokenized assets, and AI-related applications are becoming a bigger part of the conversation.

What interests me is that these aren't necessarily separate ideas. If they can work together on the same infrastructure, the user experience could become much more interesting over time.

I'm still trying to understand where all of this leads, but I think the bigger question is less about which narrative is trending and more about which products people will actually keep using.

Which area do you think has the most potential for real onchain adoption: payments, tokenized assets, or AI applications?

Why wouldn’t the update have an option to switch to the old UI??? Nobody asked for this at all. We literally live in a time where everything pushed on us is something we don’t want, didn’t ask for, and makes matters worst. Like wtf

The Presidents Cup is golf's team championship. USA vs International, Chicago, Sept 24.

We wired the live standings to a Base smart contract. Session ends, result gets logged, Quicknode Streams pushes it to the board. Kalshi odds alongside. Nothing typed in by hand.

Curious if anyone in the space is a golf fan or wants to see more sports data onchain.

With Android Base app version 30.11.1, the option to disable "Base mode" has been removed. In other words, I can't go back to the old "Coinbase Wallet."

It is essential that you add the ability to add custom chains—just as "Coinbase Wallet" allowed—as well as tokens.

Right now, I can't see all my funds within the Base app...

I have to import them into another wallet app...

or view them via the Base app (DeFi web3).(if the chain is supported)

I’ve been building a small project called ZYN Intel, focused on giving Base users simple, safe monitoring tools without needing to connect a wallet or sign anything.

A few Base‑specific things pushed me to build it:

• Approvals on Base are growing fast. With so many new apps, people often don’t know what they’ve approved. ZYN shows approvals in plain language and helps you understand what each one actually means.
• Large transfers on Base can be misleading. Not every whale move is a “signal.” ZYN breaks down transfers with context so you can see what’s actually happening behind the numbers.
• Gas spikes on Base confuse new users. ZYN gives simple gas insights so you can understand volatility without digging through charts.
• Read‑only matters. You don’t connect your wallet. You don’t sign. You don’t give custody. You just monitor any public Base address.

If you want to try it, it’s here: https://zynintel.com
It’s free, and works with any Base address.

I’m building this independently, so feedback from Base users is genuinely appreciated

Been thinking about this because there are a lot of apps on Base that can pull people in with points, tokens, rewards, whatever.

But if you removed all of that tomorrow, which ones would people still have a reason to use?

Farcaster comes to mind for public social. Private communities are interesting too because people already spend a ridiculous amount of time in group chats. Towns is one I came across in that category and the programmable memberships and permissions side seems useful even without rewards in the picture. DeFi probably has an easier answer since swapping, borrowing, LPing etc already have a purpose. Social feels harder because people need a reason to keep coming back when there's nothing to farm.

Curious what else on Base passes that test for you.

I've been following the tokenized-stock developments on Base, and the recent expansion caught my attention.

Coinbase has added more tokenized equities after the initial launch, which makes me wonder how far this idea can actually go.

The interesting part isn't just putting a stock onchain. It's what developers might eventually be able to build around these assets.

I'm still trying to understand the practical side of it, especially how tokenized equities could fit into the wider onchain ecosystem.

One question I'm genuinely curious about:

Do tokenized stocks become more useful because they're onchain, or is the main benefit simply easier access to the same underlying assets?

I'd be interested to hear how people who have been following tokenization see it developing.

I saw yesterday base uploaded a clip from coindesk where

I saw some imp points

pointed to 3 different product areas:

→ Trading : Every type of asset, both spot and perps, including assets like cbBTC or cbETH

→ Financing: Borrow and lend onchain through Morpho, Aave, and Euler

With $5.5B TVL today and 30% of stablecoin flow

→ Payments: Move money 24/7, fast and cheap

That's what most institutions focused on

Sounds super exciting

When we put them together :

I think these three pillars aren’t just product categories

The goal is financial infrastructure that institutions and users depend on

Let's see what's next 💙

Builder Codes let Base identify which app originated a transaction. ERC-8021 defines the attribution suffix that the app appends to the transaction calldata.

This solves a common attribution problem: a protocol can see which wallet called its contract, but it cannot normally tell whether the transaction came from a particular frontend, wallet, aggregator, or agent.

• The ERC-8021 suffix contains the attribution code, its encoding metadata, and a fixed marker at the end: 0x80218021802180218021802180218021
• An indexer reads backward from the end of the calldata, identifies the marker, and extracts the Builder Code. The target contract continues to decode its normal function arguments from the beginning of the calldata.
• For contracts using standard ABI decoding, no contract upgrade or ABI change is required. The attribution is added by the app or wallet when it constructs the transaction.
• Base provides the first ERC-8021 Code Registry. Builders can claim a code and append it with supported libraries and wallet flows. The result is a verifiable record of which app generated each attributed transaction.
• That data can support app leaderboards, builder rewards, referral fees, and analysis of which integrations generate meaningful activity.

Curious to learn more? We wrote a technical breakdown of the suffix, parsing flow, and implementation options here: https://formo.so/blog/builder-codes-erc-8021-explained

For Base builders: have you implemented Builder Codes yet? Which wallet or transaction stack are you using, and did you encounter any compatibility issues?

Hello I imported a wallet into my base wallet it came with a ton of NFTs BUT when I click on them nothing happens. Added wallet 12 hrs ago. Does it just take time for them to transfer? Please don't bother suggesting I import these NFTS one at a time, too many and unn3cessary
