One Protocol

DeFi is powerful but fragmented. Users juggle 10 different apps to swap, bridge, farm yield, trade perps, and manage vaults, each with its own UI, wallet flow, and learning curve. DARA fixes this by unifying everything into one protocol with one interface: your voice. Speak in any language and DARA handles it all — token swaps aggregator, cross-chain bridging via LI.FI, lending yields on Scallop and NAVI, and autonomous treasury management through Arc's RWA-backed USDC vault. No more tab-switching between protocols. No more decoding complex UIs. A first-time DeFi user can say "swap 10 SUI to USDC and put it somewhere safe" and the agent routes, executes, and confirms in their language, in seconds. The AI auto-optimizer continuously scans every integrated protocol, rebalances based on live market signals, and logs every decision on-chain with clear reasoning. We didn't build another dashboard. We built the UX layer DeFi has been missing.

We built Oneprotocol as a single app where every DeFi action — swap, bridge, yield, perps, vault is accessible through one voice interface. The AI brain uses real-time bidirectional audio streaming. Users speak in almost any language and the agent processes their intent, maps it to function declarations, and triggers on-chain execution — all while speaking back naturally in the same language. Swaps go through Aftermath Router SDK, which aggregates across Sui DEXs for best pricing. Lending yields are pulled from Scallop and NAVI protocol APIs. DeepBook V3 provides order book depth data. Bluefin's REST API feeds us perpetual funding rates across SUI-PERP, ETH-PERP, and BTC-PERP — we annualize these to surface basis trade opportunities the agent can recommend. For cross-chain, LI.FI SDK handles bridging and multi-chain swaps with automatic route optimization, so users just say "bridge USDC to Arbitrum" and the agent picks the cheapest route. On Arc, we deployed a custom DaraVault smart contract using Foundry (Solidity) on Arc testnet. The agent uses viem wallet clients to deposit and withdraw USDC — which on Arc is backed by US Treasury reserves via Circle. This is the autonomous safety layer: when the agent detects risk, funds move here automatically. The hacky part: we built a 60-second auto-optimizer loop that computes a weighted risk score from three live signals — CoinGecko price movements (40%), Bluefin funding rates (30%), and cross-protocol yield spreads (30%). When risk spikes, the agent autonomously moves funds to Arc's RWA vault. When markets recover, it redeploys to the highest Sui yield. Every decision gets logged on-chain with the exact reasoning and a link to ArcScan. Voice command to signed transaction takes under 3 seconds — the function call output pipes directly into transaction builders with zero middleware.
