Decibel is creating a new model for global, on-chain trading. Using Aptos’ high-speed technology and a fully on-chain central limit order book, Decibel brings together speed, transparency, and composability in one system.
The platform supports spot, perps, margin, and programmable strategies through a single trading engine. With its open design and strong ecosystem support, Decibel aims to become the core infrastructure for the next generation of decentralized markets.
What Is Decibel?
Decibel is a trading platform built on the Aptos blockchain. It brings spot trading, perpetual futures, margin trading, and vault strategies into one system. According to its documents, Decibel runs fully on-chain, which means every order and action is recorded on the blockchain.
The project launched on Aptos Devnet in August 2025. It was created by the Decibel Foundation together with Aptos Labs, and the foundation plans to guide the long-term growth of the platform.
A Fully On-Chain, Composable Trading Engine
Decibel uses a central limit order book (CLOB) where all orders are matched on-chain, not off-chain. The rules of the matching engine, such as price–time priority, are written directly in the Move programming language. This means users can see and verify every match and order change.
Decibel runs on Aptos’ Block-STM, which allows many transactions to happen in parallel. Because of this, Decibel can offer:
- ~0.125-second block time
- Low fees, costing only fractions of a cent
- High throughput, with the ability to process tens of thousands of orders per second
In addition, the platform is building a special trading virtual machine, which aims for sub-20 ms block times and support for over 1 million orders per second.
Decibel also supports many types of collateral in one account, such as APT, USDC, BTC, ETH, and SOL. Because of this unified design, users can trade different products with a single balance.
The Mission Behind Decibel
Decibel states that its mission is to solve a major problem in crypto trading: the tradeoff between speed, transparency, and composability. For years, traders could usually get only two:
- CEXs were fast, but not transparent.
- DEXs were transparent, but often slow.
- DeFi protocols were composable, but sometimes lost speed or flexibility.
Decibel’s goal is to remove these tradeoffs by running everything on-chain while using Aptos’ fast and parallel system. Because of this approach, the project aims to make trading both fast and transparent, while also supporting DeFi integrations in one place.
The platform also wants to reduce the fragmentation of current markets. Many traders must switch between platforms for spot, perps, and yield. Decibel’s mission is to bring these experiences together in a single system.
Why Decibel Is Becoming a Category-Defining Platform
| Key Point | Simple Explanation | Data / Details |
|---|---|---|
| 1. Everything Happens On-Chain | All orders are matched on-chain, not off-chain. Users can see and verify all actions. | No off-chain sequencers; price–time priority enforced in Move. |
| 2. High Speed Similar to CEXs | Decibel offers very fast trading, similar to centralized exchanges. | ~0.125-second finality; low fees; planned sub-20 ms block times; over 1,000,000 orders per second. |
| 3. One Unified Market System | Spot, perps, margin, and vaults share one margin account, so users manage funds easily. | All products use one cross-margin, multi-collateral account. |
| 4. Strong Composability With DeFi | Decibel connects with other protocols and supports building on top of it. | Vault tokens, builder tools, and fully on-chain CLOB allow developers to integrate trading features. |
| 5. Easy Cross-Chain Funding | Users can deposit funds from many chains or even centralized exchanges. | Supports Aptos, Ethereum, Solana, and CEX deposits via cross-chain accounts. |
How Decibel Works
Built on Aptos — Speed at the Core
Decibel is built on the Aptos blockchain, which gives the platform very fast and low-cost trading. Aptos uses a system called Block-STM, which allows many transactions to run at the same time, instead of one by one. Because of this, Decibel can offer very fast performance.
| Sub-second finality | Aptos provides sub-second finality, with block times of about 0.125 seconds. This means trades finish almost instantly. |
| Parallel execution with Block-STM | Block-STM lets different trades and transactions run in parallel, helping Decibel handle high throughput and keep the system stable even when many users are trading at the same time. |
| Near-zero fees | Because Aptos is efficient, trading on Decibel costs only fractions of a cent, which helps active traders keep costs low. |
The Decibel Trading VM
Decibel is building a special trading virtual machine (VM) to increase performance even more. According to the documents, it will help support very fast block times and extremely high order volume.
Sub-20 ms block times
The new VM aims to reach sub-20 millisecond block times, which is much faster than typical blockchain speeds.
1 million orders per second
The VM is designed to handle over 1,000,000 orders per second, allowing Decibel to support heavy trading activity.
On-chain order matching (no off-chain manipulation)
All orders are matched fully on-chain, with rules written directly in Move. There are no off-chain sequencers, which means traders can check and verify every action. This also removes the chance for hidden or manipulated order flow.
Unified Market Structure
Decibel brings different types of trading into one programmable engine, so users do not need to switch platforms. The system is designed to keep liquidity active, reduce fragmentation, and make capital use more efficient.
Spot, perps, margin in one engine
Spot markets, perpetual futures, and margin trading all run inside the same system. Because of this unified design, markets share liquidity and execution quality.
Cross-margin, multi-collateral accounts
Users can hold many assets, such as APT, USDC, BTC, ETH, and SOL, in one cross-margin account.
This means the same balance can be used for different types of trades.
Composable risk and margin models
Decibel’s margin system is programmable and can connect with other DeFi tools. Vaults and strategies can plug into the trading engine, and builders can design their own models using Decibel as the base layer.
5 Key Features That Make Decibel Unique
1. True Composability Across DeFi
Decibel is built to connect easily with other DeFi tools and systems. Because everything runs on-chain, builders can create new products on top of Decibel without changing the core engine.
- Builder Codes: Decibel offers tools for developers called Builder Codes. These tools help builders plug their own apps or trading strategies directly into the Decibel engine.
- Vault deposit tokens: When users deposit into a vault, they receive vault tokens. These tokens can move around the wider DeFi ecosystem, so users can use them in other protocols while still earning from the vault.
- Integrating external protocols natively: Because Decibel is fully on-chain, external DeFi protocols can connect directly to its order book and trading system.
2. Transparency Without Sacrificing Performance
Decibel’s design focuses on keeping all actions transparent while still being very fast. Since everything is recorded on-chain, users can always check how the system works.
| Feature | Simple Explanation | What This Means for Users |
|---|---|---|
| 100% on-chain CLOB | Decibel uses a fully on-chain central limit order book. There are no off-chain steps in the matching process. | All trades are processed openly on the blockchain, so nothing is hidden. |
| Price–time priority written in Move | All matching rules—such as price–time priority—are written directly in the Move language. | Rules cannot be changed in secret because they are written in open, on-chain code. |
| Fully auditable, no hidden matching engine | Because everything runs on-chain, the whole system is auditable. Users can see every order, fill, and cancellation. | There is no hidden engine or private queue, so traders get equal treatment. |
3. CEX-Level Speed, DeFi-Grade Control
Decibel aims to give users the speed of a centralized exchange while keeping the transparency of DeFi. Because of Aptos’ high performance, trades are both fast and fair.
- No trusted sequencers: Decibel does not use trusted sequencers. Instead, the blockchain itself handles ordering and execution.
- No offchain execution shortcuts: There are no off-chain shortcuts, meaning all execution follows the same rules and is visible to all users.
Added to this is the fact that the system uses code-based rules to make sure all traders follow the same process. Because everything is automated, fairness does not depend on people or private systems.
4. Always-On Liquidity
Decibel includes several types of vaults to help keep markets deep and active at all times. These vaults play an important role in making trades smooth and stable.
| Protocol-managed liquidity vaults | The protocol operates its own liquidity vault to support market-making and liquidation processes, helping keep markets stable and efficient. |
| User-managed vaults | Users can create and manage their own vaults, each able to run different trading or liquidity strategies, adding additional depth and flexibility to the platform. |
| Market-making & liquidation strategies | Both protocol and user vaults may run market-making or liquidation strategies, helping stabilize prices and ensure fast order execution. |
5. Cross-Chain Accounts
Decibel supports simple and flexible funding by allowing users to deposit from multiple chains. This makes it easier for new users to join the platform.
| Feature | Description |
|---|---|
| Fund from Aptos, Ethereum, Solana, CEXs | Users can fund their accounts using Aptos, Ethereum, Solana, or centralized exchanges (CEXs), making onboarding much easier. |
| No new seed phrases | Users can use their existing wallets; no need to generate new seed phrases. |
| Seamless onboarding | Users can bring funds from multiple chains without creating new accounts, enabling fast and simple onboarding. |
The “Impossible Trilemma” and How Decibel Solves It
The November 2025 document explains a long-standing problem in crypto trading called the “Impossible Trilemma.” It says that most trading systems cannot reach speed, transparency, and composability all at the same time. Usually, a platform can offer only two of them. This has limited both CEXs and DEXs for years.
Traditional Tradeoffs (Speed vs. Transparency vs. Composability)
Most exchanges face a difficult choice. If they try to increase one part of the system, another part gets weaker. The document explains that this has created the same pattern across the industry.
Typical Tradeoff Patterns
| What the Platform Chooses | What It Gains | What It Loses |
|---|---|---|
| Speed + Composability | Fast systems, flexible design | Low transparency |
| Transparency + Composability | Open data, easy to build on | Slow performance |
| Speed + Transparency | Fast and open | Limited building options |
Because of this, no system has managed to deliver all three at the same time.
Why CEXs Can’t Be Fully Transparent
Centralized exchanges (CEXs) are known for their speed, but the document explains why they cannot reach full transparency.
CEXs depend on:
- Private matching engines
- Hidden internal order books
- Servers that cannot be audited
- Off-chain execution systems
This means the public cannot see how orders are matched or why certain trades happen. Even if the exchange performs well, users must trust it without proof.
Why Most DEXs Sacrifice Speed
Decentralized exchanges (DEXs) choose transparency, but they often lose speed. This is mainly because:
- Blockchains usually run in sequential execution (one step at a time).
- Busy markets cause network congestion.
- Delays increase when demand grows.
As a result, many DEXs become slow during peak trading times, even though they remain transparent.
How Decibel Re-architects the Trilemma
Decibel takes a different path. Instead of choosing two qualities, it redesigns the full trading engine so it can support speed, transparency, and composability together.
The document highlights three technical pieces that make this possible.
1. Parallel Execution
Decibel uses Aptos’ Block-STM system. This allows the blockchain to process many actions in parallel, not one-by-one.
What parallel execution brings:
- Higher throughput even during busy market hours
- Lower latency, giving faster trade updates
- More stable performance for heavy trading loads
This helps Decibel reach high speed while staying transparent.
2. Fully On-Chain CLOB
A major difference is that Decibel’s central limit order book (CLOB) is 100% on-chain. There are no off-chain sequencers, private servers, or hidden matching steps.
Key Transparency Benefits
| Feature | What It Means |
|---|---|
| Fully on-chain order matching | Every order and fill is visible to the public |
| No private queues | No user gets secret priority |
| Price–time priority coded in Move | Matching rules cannot be changed secretly |
| Fully auditable | Users can inspect the entire trading process |
Because of this, traders get transparency without losing speed.
3. Atomic Composability
The document also explains that Decibel supports atomic composability, which lets smart contracts interact inside the same transaction.
This enables:
- Easy integration with other DeFi protocols
- Smooth connection for vaults, strategies, and apps
- More flexible building options for developers
With this, Decibel keeps composability while still offering fast and transparent execution.
Summary Table: How Decibel Solves the Trilemma
| Trilemma Feature | Traditional Platforms | Decibel’s Approach |
|---|---|---|
| Speed | CEXs only | Parallel execution (Block-STM) |
| Transparency | DEXs only | Fully on-chain CLOB |
| Composability | Slow DEXs only | Atomic composability |
Decibel combines all three by reshaping the core architecture—from execution to matching to integration.
Perpetual Futures on Decibel
Perpetual futures, or perps, are a major part of Decibel’s trading system. The project explains how perps stay close to spot prices, why they do not form a circular loop, and how funding payments help keep markets in balance.
How Perps and Spot Stay Aligned
Decibel describes the link between perps and spot markets using a rubber-band analogy. Perp prices can move away from spot prices for a short time, but natural incentives pull them back together.
Rubber-band analogy
Think of spot and perp prices as two ends of a rubber band. They can move apart, but tension pulls them back into alignment. That “tension” comes from funding payments and trader behavior.
Funding rate incentives
Funding rates are small payments between long and short traders. They work like this:
- If the perp price is higher than spot → Longs pay shorts
- If the perp price is lower than spot → Shorts pay longs
Because traders want to avoid paying funding, they adjust their positions. This push and pull helps close the price gap.
Arbitrage flows
When prices drift too far apart:
- Traders buy the cheaper market
- And sell the more expensive market
This simple arbitrage action tightens the spread and brings the two prices back together.
Why Perps and Spot Do Not Create a Circular Reference
The Decibel document explains clearly that perps and spot do not feed into each other in a circular or unstable way. Instead, trader behavior keeps the system stable.
Delta-neutral strategies
Some traders run delta-neutral trades (equal long and short positions). They do not care about the direction of the price. They only care about:
- Funding payments
- Price gaps
- Arbitrage opportunities
Because these traders act whenever prices drift apart, they help keep both markets aligned.
Trader behavior during dislocations
When perp prices jump away from spot, traders respond quickly:
- If perp > spot → more traders short the perp
- If perp < spot → more traders long the perp
Their activity pulls the prices back together.
Self-correcting incentives
The system has built-in rewards for correcting price differences. This is why the Decibel paper says mispricing does not spiral—it fixes itself through natural trading incentives.
| What Funding Is | Funding keeps perp prices close to spot prices. It is not a fee to the exchange — it is a payment between traders. |
| When Longs Pay Shorts | Longs pay shorts when the perp price is above the spot price. This incentivizes shorting, which pushes the perp price down. |
| When Shorts Pay Longs | Shorts pay longs when the perp price is below the spot price. This incentivizes going long, which pushes the perp price up. |
| How Funding Closes Price Gaps | Funding continually applies pressure to close price gaps: • If perp > spot, funding pushes perp down. • If perp < spot, funding pushes perp up. |
This is why perps and spot stay close most of the time, and why the system remains stable and predictable.
The Decibel Ecosystem and Governance
Decibel is more than a trading engine. Its documents describe a full ecosystem supported by a long-term governance structure, the Decibel Foundation. This structure is designed to keep Decibel neutral, transparent, and aligned with the Aptos community.
The Decibel Foundation
The Decibel Foundation is responsible for helping the protocol grow over time. It acts as a neutral guide instead of a private operator. In August 2025, Decibel announced the appointment of a new inaugural CEO, marking an important step in building global, on-chain markets.
Later communications from the Mr. Ming shared that he has transitioned into an advisory role as the company enters its next stage of growth.
Quick Overview: Decibel Foundation
| Topic | Explanation |
|---|---|
| Neutral steward of the protocol | The foundation stays independent so no single group controls the trading engine or liquidity system. |
| Long-term ecosystem alignment | Works with Aptos Labs and the community to guide upgrades, partnerships, and development. |
