Yieldera.
Yieldera is an AI-powered automated liquidity management protocol built for the Hedera network. It executes intelligent vault strategies across SaucerSwap (Uniswap V3) concentrated-liquidity positions and Bonzo lending pools, pairing Solidity smart contracts on Hedera EVM with a high-concurrency Rust backend and a dedicated Model Context Protocol (MCP) server that empowers Gemini agents to safely inspect and optimize on-chain capital.

System at a glance
What the system does
Automated concentrated-liquidity rebalancing
Model Context Protocol (MCP) blockchain tooling
SaucerSwap V3 & Bonzo Finance multi-protocol routing
Hedera Token Service (HTS) & EVM vault mechanics
Architecture flow
From intent to verified state.
- 01
Users deposit native HBAR or HTS assets (USDC, SAUCE) into the YielderaVault smart contract, receiving proportional shares.
- 02
A Tokio-powered Rust backend continuously evaluates pool tick ranges, price volatility, and liquidity depth on SaucerSwap.
- 03
Automated rebalancing algorithms compute optimal price bounds to maximize trading fee capture while mitigating impermanent loss.
- 04
A specialized Rust MCP server exposes deterministic blockchain tools (balances, Bonzo lending, tick calculations) to a Gemini AI agent.
- 05
The React dashboard provides real-time telemetry, multi-wallet connectivity (HashPack, Blade, Kabila, MetaMask), and natural-language AI interactions.
01 / Smart contracts
Hedera-native vaults with concentrated liquidity mechanics
Core custody and liquidity deployment engineered in Solidity for Hedera's EVM layer and SaucerSwap pools.
SaucerSwap V3 integration
Coordinates concentrated-liquidity positions on SaucerSwap (Uniswap V3 model), executing automated position mints, burns, fee collections, and rebalancing directly against decentralized pool contracts.
HTS & native asset handling
Natively supports HBAR and Hedera Token Service (HTS) tokens such as USDC and SAUCE, enforcing precision normalization, token associations, and safe transfer boundaries.
Fee compounding & share accounting
Trading fees and incentive rewards are systematically harvested and reinvested into active tick ranges, updating internal vault share valuations without exposing reentrancy attack surfaces.
Foundry verification & safety
Developed and tested with Foundry forge suites, featuring verifiable deployment scripts targeting Hedera testnet and mainnet with HashScan and Sourcify contract verification.
02 / Backend engine
Asynchronous Tokio & Actix Web liquidity management
A high-throughput Rust service orchestrating multi-vault telemetry, automated rebalance triggers, and administrative controls.
Concurrent multi-vault state
Maintains lock-free concurrent runtime state across all managed vaults using DashMap and dedicated Tokio worker tasks, preventing head-of-line blocking during network latency spikes.
Automated rebalancing triggers
Continuously evaluates market price deviations against configured tick tolerances, initiating contract rebalances when positions shift outside profitable fee-generating intervals.
Alloy & typed RPC bindings
Utilizes Alloy full-suite providers and Solidity type bindings for high-throughput, type-safe RPC communication with Hedera JSON-RPC relays.
Production OpenAPI & telemetry
Exposes vault management and monitoring endpoints documented interactively via Utoipa Swagger UI, accompanied by structured file and console logging via tracing-subscriber.
03 / Agentic AI & MCP
Model Context Protocol tooling for verified blockchain execution
Bridging large language models to on-chain financial operations through typed, deterministic MCP primitives.
Rig framework integration
Connects Google Gemini models with the Rig agent framework to parse natural-language portfolio inquiries and generate actionable liquidity strategies.
Deterministic MCP tools
A standalone Rust server implements the Model Context Protocol, exposing secure tools for account balance queries, token transfers, and Bonzo lending protocol interactions.
Mathematical verification tools
MCP calculator modules compute exact tick math, fee APY projections, and impermanent loss simulations before any strategy recommendation is delivered.
Advisory-first safety boundary
Keeps generative reasoning strictly advisory; execution parameters are rigorously bounded by smart contract validation and admin permission checks.
04 / Cross-protocol DeFi
Synergistic yield between SaucerSwap and Bonzo Finance
Bonzo lending market integration
Allows idle liquidity and rebalancing reserves to be supplied directly into Bonzo Finance lending pools, generating continuous baseline interest alongside DEX fees.
Capital efficiency balancing
Dynamically reallocates capital between active DEX trading ranges during high-volume periods and money-market lending during low-volatility regimes.
Hedera ecosystem wallet UX
Integrates both Hedera native account formats and EVM addresses across HashPack, Blade, Kabila, and MetaMask wallets within a real-time cyberpunk dashboard.
