Decibel is a perpetual futures exchange where every order is placed, matched, and settled on-chain. If you have traded perps before, you already know how to use Decibel.

​
Get Started

  1. Connect any wallet. EVM (MetaMask, OKX, Ledger), Solana (Phantom, Solflare), or Aptos (Petra, Aptos Connect).
  2. Deposit USDC. Click Deposit and select the chain your USDC is on. Decibel bridges it automatically.
  3. Trade. Perps with up to 40x leverage, cross-margin by default.
  4. Withdraw. Send USDC back to the chain your wallet is connected to.

​
Supported Chains

Deposit and withdraw USDC from any of these chains:
ChainWallets
EthereumMetaMask, OKX, Ledger, any EIP-1193 wallet
ArbitrumSame as Ethereum

Bridging uses Wormhole with Circle’s CCTP for USDC transfers. You do not need to bridge manually.

​
Fees

Trading fees decrease as your 30-day volume grows. Maker fees drop to zero at higher tiers.

​
What Makes Decibel Different?

  • Fully on-chain. The orderbook lives on-chain, not just settlement. Every order, match, and fill is a transaction you can verify.
  • Cross-chain deposits. Connect your existing wallet from Ethereum, Arbitrum, Base, or Solana. No manual bridging.
  • Continuous funding. Funding accrues continuously instead of resetting every 8 hours, reducing the manipulation windows common on other exchanges.
  • Builder Codes. Third-party apps and bots can earn a share of trading fees through Builder Codes.

​
Vaults

Not trading directly? Deposit into a vault and let a professional manager trade on your behalf.
  • Fungible vault shares. Your share of the vault is a token you can hold or use elsewhere in DeFi.
  • Skin in the game. Vault managers deposit their own capital alongside contributors.
  • Interval-based performance fees. Managers charge 0-10%, crystallized every 30-365 days. If the vault loses money in an interval, no fees are charged for that period.
  • Fully on-chain. Vault creation, deposits, redemptions, and fee logic all execute as on-chain transactions.
Want to run a vault yourself? See the Vault Launch Guide for developers, or Vaults for how they work as a contributor.

​
Under the Hood

Decibel runs natively on Aptos Layer 1. For traders this means fast execution and low gas, but you do not need to know anything about Aptos to use Decibel. Connect your existing wallet, and the cross-chain infrastructure handles the rest. For the technically curious:
  • Block-STM parallel execution. Transactions process in parallel, not sequentially.
  • Sub-second finality. Settlement in roughly 0.125 seconds.
  • Move VM. Smart contracts written in Move, a language designed for safe asset handling.
  • No bridges or rollups. All liquidity lives on a single L1. No fragmentation, no bridge risk.
