Products & Services

Backyard Finance is a yield infrastructure where users build diversified yield strategies by allocating across multiple yield vaults (e.g. Kamino, Jupiter, OnRe). These strategy LP tokens can optionally be used to mint Backyard Dollar (BYD), allowing users to earn yield while retaining liquidity.

By separating yield generation from liquidity, Backyard solves one of DeFi’s core inefficiencies: capital locked in yield strategies that cannot be reused without exit friction.

The protocol is governed by a ve(3,3)-style capital coordination system, aligning emissions, governance, and liquidity incentives to route capital toward the safest and most productive strategies over time and provide better returns for users.

What we're building/improving:

1. Multi-vault yield strategy engine. A Soroban smart contract that lets users publish deposit intents and allocate across multiple yield vaults in a single transaction. Stellar is used for all on-chain strategy logic, settlement, and LP token issuance.

2. Keeper automation network. A permissionless bot that resolves user intents and routes capital to the correct vault. When the deposit asset differs from the vault asset, it automatically swaps via StellarX DEX before depositing. This makes any Stellar asset a valid entry point.

3. Indexer & transaction history. An event-driven indexer (e.g. Stellar-etl) that tracks all on-chain strategy activity, enabling portfolio dashboards and full transaction history for users.

4. Backyard Dollar (BYD) minting (not in this submission). Strategy LP tokens can be used to mint BYD, a liquidity token that lets users earn yield while retaining capital access, solving the locked-capital problem common in DeFi yield strategies.

5. ve(3,3) governance (not in this submission). A capital coordination layer that aligns emissions and liquidity incentives toward the safest and most productive vaults over time.

All core protocol logic runs natively on Stellar/Soroban. The integration deepens Stellar's DeFi composability by connecting Blend, DeFindex, Spiko, and other protocols into a public unified yield layer accessible to any wallet via Stellar Wallet Kit.

Tranche 1 (Deliverable Roadmap) - MVP

Deliverable 1: Smart Contract Core (MVP / Strategy Foundation)

Create a diversified yield strategy on Stellar by allocating funds across multiple Blend vaults, so that I can earn optimized yield without manually managing each position.

Scope:

Smart contract logic for strategy creation and management, deployed on Soroban
Blend vaults integration - deposit/withdraw interface exposed through the strategy contract
Publish intent mechanism - users submit deposit intents to the contract on-chain
Basic contract events emitted for downstream indexing

Acceptance Criteria:

Soroban smart contract deployed to Stellar testnet
Users can create a multi-vault strategy
Blend vaults deposits and withdrawals fully functional via the strategy contract
Intent publication on-chain and event emission verified
Contract logic unit-tested with full coverage of happy-path and edge-case scenarios
Internal code review completed

Tranche 2 (Deliverable Roadmap) - Testnet

Deliverable 2: Frontend, Backend, Indexer, Keeper Automation & Definex integration

Connect Stellar wallet, pick a yield strategy, deposit any asset, and have it automatically routed into the correct vault, so that user can participate in yield generation without technical complexity.

Scope:

Frontend DApp with Stellar Wallet Kit integration (wallet connect, balance display, strategy UI)
Strategy setup UI - vaults selection, asset input, custom allocation by selected vaults, deposit intent submission
Backend service - transaction assembly relay between Soroban and the frontend
Indexer - on-chain event listener, state persistence to DB, message queue producer
Keeper bot - permissionless automation that resolves intents and routes funds to vaults
StellarX swap integration - enables any-asset entry when deposit asset differs from vault asset
DeFindex vault integration - deposit/withdraw interface integrated alongside Blend

Acceptance Criteria:

Frontend connects to Stellar wallets via Stellar Wallet Kit on mainnet
Users can create and submit a yield strategy fully from the UI
Backend correctly assembles and relays serialized transactions from Soroban
Indexer reliably captures all contract events and persists state to the database
Keeper bot processes intents end-to-end: queue consumption > asset check > vault deposit
StellarX swap correctly executes when deposit asset does not match vault asset
DeFindex vault deposits and withdrawals operational
Full deposit flow tested on mainnet from wallet connect through vault settlement

Tranche 3 (Deliverable Roadmap) - Mainnet

Deliverable 3: Analytics, Automated rebalancing & Protocol Expansion

Clear view of users’ portfolio performance, automated rebalancing across vaults, and access to a growing set of yield protocols, so that users can maximize returns while minimizing manual effort.

Scope:

Analytics dashboard - portfolio performance, APY breakdown per vault, historical yield
Transaction history - full on-chain activity log per strategy and vault on UI
Automated rebalancing - Keeper-driven position adjustments when triggered position size,APR, TVL, etc.
Manual rebalancing UI - custom deposit and withdrawal to/from individual vaults or strategies
Spiko yield vault integration - deposit/withdraw interface integrated alongside Spiko
Additional protocol integrations - extensible vault integration framework for future protocols

Acceptance Criteria:

Analytics dashboard live with real-time APY and portfolio data per strategy
Transaction history visible and filterable in the UI for all past activity
Keeper bot executes automated rebalancing based on configurable strategy weights
Manual rebalancing (custom deposits/withdrawals) functional from the UI
Spiko vault deposits and withdrawals live and integrated with the Keeper routing logic
At least one additional protocol integrated and documented
Full regression test suite covering all three deliverables passed on mainnet
Mainnet launched
