By Stabble
High-velocity liquidity layer for decentralized stablecoin exchange—optimized for near-zero slippage trades and low execution costs on Soroban.
Stellar Integration: Deployed as native Soroban smart contracts interacting with the Stellar Asset Contract (SAC) for atomic swap execution across Stabble vaults.
Impact: Maximizes capital efficiency, allowing the protocol to capture competitive trading volumes with significantly less liquidity than traditional AMMs, boosting protocol APY.
Stellar Integration: Leverages Soroban’s cross-contract calls and auth framework to ensure secure and fully atomic execution within a single transaction. Single-asset deposits are supported through automated rebalancing logic.
Impact: Enables efficient asset routing within the Soroban ecosystem while simplifying LP experience, maximizing capital utilization and reducing manual management.
Stellar Integration: Uses Soroban smart contract architecture to host up to 5 tokens in a single STBS vault, with compatibility across Stellar Classic assets and Soroban tokens via SAC.
Impact: Reduces liquidity fragmentation across the Stellar ecosystem, enabling deeper markets, improved execution, and more efficient routing within Soroban-native liquidity.

Stabble Track Record & Solana Traction
Stabble is a battle-tested protocol with significant mainnet traction on Solana, demonstrating institutional trust and product-market fit.
Our performance metrics highlight the efficiency of our "Smart Math" and StableSwap invariants:
Trading Volume: $29.8B+ lifetime volume facilitated; $600M peak 24h volume.
Liquidity & TVL: $8M peak TVL; currently >$418k.
Activity: 30-day trading volume >$148M; 7-day volume >$2.8M.

Brief description
Implementation of the core Stabble AMM logic on Soroban, including the StableSwap invariant and pool execution logic, adapted from the Solana codebase to a Soroban-compatible Rust implementation.
How to measure completion
Successful deployment of a basic Vault contract on testnet
Unit tests validating invariant behavior (stable pairs, low slippage scenarios)
Execution of basic swaps (Asset A → Asset B) on testnet
Estimated date of completion: 15.07.2026
Budget: $24,200
Deliverable 2: SAC Integration & Basic Pool Support
Brief description
Integration with Stellar Asset Contract (SAC) to support native Stellar assets (e.g. USDC, EURC), enabling deposits, withdrawals, and swaps within Soroban contracts.
How to measure completion
Testnet deployment supporting SAC-compatible tokens
Successful deposit, withdrawal, and swap flows using real Stellar assets
Integration tests validating token transfers via SAC
Estimated date of completion: 15.07.2026
Budget: $15,400
⚠️ Important: Routing is strictly limited to Soroban-native components to ensure atomic execution within a single transaction.
How to measure completion
Testnet deployment of the Router contract
Execution of atomic multi-hop swaps (e.g. Asset A → Asset B → Asset C) in a single transaction
Demonstration that all swaps revert if one hop fails
Estimated date of completion: 15.08.2026
Budget: $20,900
Deliverable 2: Vault Factory & Registry
Brief description
Implementation of the Factory contract responsible for deploying and managing Vaults, using Soroban storage patterns optimized for scalability and low footprint.
How to measure completion
Testnet deployment of Factory contract
Successful creation of new Vaults via Factory
Registry of deployed pools accessible on-chain
Estimated date of completion: 01.09.2026
Budget: $14,300
Deliverable 3: Basic Single-Asset Deposit Mechanism (Simplified SLR)
⚠️ This is a simplified MVP version (no full SLR / PMA yet).
How to measure completion
Successful single-asset deposit (e.g. USDC → multi-asset pool)
Verification of internal allocation logic
Functional deposit/withdraw flow
Estimated date of completion: 15.09.2026
Budget: $11,000
Brief description
Integration of a Soroban-compatible oracle (e.g. Reflector or Band) to monitor asset prices and enforce risk controls (e.g. depeg protection).
How to measure completion
Integration of oracle price feed
Implementation of staleness checks and thresholds
Demonstration of protocol safety mechanism (e.g. pause or revert when deviation > threshold)
Estimated date of completion: 09.10.2026
Budget: $22,000
Deliverable 2: Frontend Integration & User Flows
Brief description
Development of a public interface allowing users to interact with the protocol (swap, deposit, withdraw) and monitor pool activity.
How to measure completion
Functional web interface connected to testnet/mainnet contracts
Ability to execute swaps and liquidity operations from UI
Display of basic metrics (TVL, volume, pools)
Estimated date of completion: 23.10.2026
Budget: $16,500
Deliverable 3: Mainnet Deployment & Initial Liquidity
Brief description
Deployment of core contracts (Vaults, Factory, Router) on Stellar mainnet and initialization of first liquidity pools.
How to measure completion
Contracts deployed on mainnet with verified source
Execution of first real swaps on mainnet
Initial liquidity seeded in stablecoin pools
Estimated date of completion: 03.11.2026
Budget: $19,800
