Built on Aptos, the on-chain trading platform Decibel is today launching BTC-USDC and APT-USDC spot markets, expanding its offerings beyond perpetual futures for the first time. This launch integrates spot trading, perpetual contract trading, and collateral management into a single account, providing traders with a broader suite of tools without requiring asset transfers across platforms.
Spot trading on-chain has been steadily growing, and this launch aligns with this trend. In June 2026, decentralized exchanges processed $195 billion in spot trading volume, a 9.1% increase from the previous month. Over the longer term, the share of decentralized spot trading volume relative to centralized exchange volume has risen from 6% in January 2021 to 21.2% in November 2025.
The addition of spot trading functionality expands what traders can do on the Decibel platform. Users can now hold BTC or APT, trade these assets directly, use eligible spot positions as collateral, and hedge positions through perpetual contracts from the same account. This creates a more comprehensive portfolio management workflow. For example, a user looking to hold a long-term BTC position can manage short-term downside risk using perpetual contracts while continuing to hold the underlying asset—without selling it or transferring funds to another platform.
Brylee Whatley, Head of the Decibel Foundation, said: “Decibel began with perpetual contracts because that’s where on-chain trading activity was primarily concentrated. But a truly mature trading platform cannot stop there. Traders want to hold assets, trade around those positions, and manage risk without having to stitch together multiple different platforms. Adding spot trading is a crucial step toward providing traders with more markets and tools on a single platform, while ensuring all these activities remain fully on-chain.”
Spot orders on Decibel are matched and settled on the Aptos mainnet without using an off-chain order book. The same on-chain infrastructure now simultaneously supports Decibel’s spot and perpetual markets. This launch also expands how traders can utilize their existing assets: eligible spot positions can now be used as collateral, allowing held BTC or APT assets to support other trading activities rather than remaining segregated from traders’ derivative positions.
Decibel supports deposits in supported assets via external wallets and supported exchange accounts, allowing traders to bring assets directly from their existing holdings onto the platform without needing to start with native Aptos assets.
This update includes:
-BTC-USDC and APT-USDC spot markets;
Trade spot and perpetual contracts through a single account;
Eligible spot holdings can be used as collateral;
- All on-chain order matching and settlement occur directly on the Aptos mainnet;

Decibel's recent cumulative trading volume has surpassed $5 billion, with all trades matched and settled on-chain, demonstrating the platform's strength and its growing user base. Additional spot markets will be rolled out in the coming period.
