There’s a mythological gold standard for going bankless that’s never quite been achieved before: a feature-complete exchange with an entirely onchain codebase.
MakerDAO, Aave, and 
Uniswap all emerged around 2018-2019, and manifested the concept of "going bankless" – all of these apps were financial primitives with fully onchain codebases. Borrowing, lending, and trading were now actions achievable in a completely onchain, disintermediated way.
The 2019 DeFi 1.0 apps were all built under the constraint of the times – 12 second blocktimes, small blocksizes, expensive gas fees. They would later become known as "Slow DeFi," i.e., DeFi apps that resonated with, and were constrained by, the physics of the underlying blockchain – Ethereum.
Ethereum DeFi broke spot, perps, margin, and lending into separate protocols on separate codebases, because the chain underneath couldn't host them under one roof, whereas a TradFi brokerage puts all of these inside a single account.
Enter World Markets – a fully onchain, feature-complete exchange live on MegaETH. World Markets has spot markets, margin accounts, perps, and borrowing/lending all built together into one universal financial platform. And critically, there is no ‘backend’ – the entire operation of the World Markets exchange is executed by code on MegaETH. No servers involved.
World Markets is constructed in a way that mirrors TradFi exchange and brokerage platforms. By having spot markets, margin, and borrowing/lending all on the same platform, World can leverage the product synergies created by controlling the entire product suite, and the entire state of the product suite being fully onchain.
World Markets’ 5 Onchain Superpowers:
- Everything Account: unified, portfolio-level margin across spot + perps + lending
- No ADL (auto-deleveraging)
- Atomic composability for strategies
- Verifiability of every state transition
- Credible neutrality of the matching engine
1️⃣ Everything Account
World collapses three previously standalone account types: spot trading, a perp position, or a margin position, into one single “universal margin account” – one single balance that collateralizes all of your positions. Their ATLAS risk engine can look at your positions as a portfolio – if you're long $100 of spot ETH and short $100 of ETH perp, it understands the trades cancel out, and stops charging margin as if those were two independent bets – a massive capital efficiency unlock.
This is how traditional brokerages work – they have a complete view of their customers' financial portfolios and can offer them products based on said portfolios, because the customers have given over custody and control to the brokerage. With World, you're handling this onchain – the bankless way.
2️⃣ No ADL
On CEXs and most onchain perp venues, when an insurance fund can't cover bad debt from a blown-out position, the system force-closes the winning trader's profitable hedged position to plug the hole. With World Markets, because the lending market and the perp market are inside the same contract system, bad debt can be absorbed by the lending book rather than confiscated from profitable hedgers. This is a direct response to the 10/10 ADL cascade that wiped out delta-neutral traders across the industry.
3️⃣ Atomic Composability for Strategies
Because the orderbook, margin, and lending pool are all contracts on the same chain, an external smart contract can – in one transaction – borrow USDC, open a perp short, buy spot, post both as cross-margin collateral, and produce an LP receipt token.
4️⃣ Verifiability of Every State Transition
Every order placement, fill, funding payment, liquidation, oracle update, and interest accrual is an onchain event. A user can reconstruct the full state of the exchange at any block. User-level verification is the heart of any bankless system.
5️⃣ Credible Neutrality of the Matching Engine
Offchain matching engines can — and historically do — front-run, prioritize VIPs, or go down during volatility. An onchain central limit orderbook (CLOB) executes by the deterministic rules deployed directly onchain. Sophisticated traders can see when they are being treated as second-class citizens. I remember, before the fall of FTX, some traders realized that their positions were getting liquidated behind someone else's (it turns out Alameda's), so they stopped trading on FTX. Code, not kings.
MegaETH Unlocks the Architecture
World Markets is uniquely made possible by the massive throughput of MegaETH.
DeFi 1.0 was a financial revolution, but growth has been constrained by poor UX and feature-incompleteness. In 2026, we have a real-time blockchain with more scale than we ever thought possible. Turns out, this is what it takes to build an onchain exchange that has the same features that TradFi can only offer via trust and custodianship.
World Markets is still a startup, and has all the execution risks that any startup has, but its founding architecture resembles a sort of ‘bankless gold standard’ that I never thought we’d ever be able to achieve in crypto.
If World Markets succeeds as an exchange, I think it will flip the perspective from “what belongs onchain?” to “what can’t go onchain?”
People are having a hard time getting excited about crypto at the moment, but it's new innovations like World Markets on top of new substrates like MegaETH that have revitalized some optimism for those left playing onchain. If and when the energy in crypto comes back, I expect it to be because apps like World were being built to solve fundamental problems during a time when only a few people still were paying attention. Godspeed to us all!
