Decibel finally launched its public testnet on Aptos, offering a trading engine that combines perpetual futures, margin trading, and vaults into one programmable system with the speed of a CEX, but with full DeFi transparency. The testnet is open to everyone, allowing traders to explore the system and compete on the leaderboard, while builders get API access and opportunities to earn through volume-based revenue sharing. @Decibeltrade, a project I have invested in, delivers sub-second execution times and volume-based fee reductions that can drop to zero, aiming for a mainnet launch in Q1 2026.(Route 2 FI)
