By BIM Exchange
BIM Exchange is a live multi-chain DeFi execution and yield optimization platform operating across EVM-compatible networks, with cross-chain routing infrastructure already in production.
This submission focuses on integrating Stellar into BIM Exchange’s existing architecture through three core Stellar-native components:
1. Stellar Wallet Integration (Stellar Wallet Kits)
BIM Exchange integrates Stellar Wallet Kits to enable users to connect Soroban-compatible Stellar wallets and interact directly with Stellar smart contracts through the BIM interface. This ensures seamless wallet connectivity, transaction signing, and asset visibility within the Stellar ecosystem.
2. Native Swap Integration (Soroswap)
BIM Exchange integrates Soroswap smart contracts deployed on Soroban to enable native asset swaps on Stellar. Stellar liquidity is incorporated into BIM’s routing engine, allowing users to execute swaps within the Stellar ecosystem using the same execution flow available across other supported networks.
This integration expands exposure of Stellar-native liquidity to BIM’s existing multi-chain user base and drives measurable swap volume on Stellar.
3. Stellar Staking & Yield Integration (Defindex)
Through integration with Defindex, BIM Exchange enables staking and yield participation on Stellar via Soroban smart contracts. Users can stake and unstake Stellar-native assets directly from the BIM Exchange interface, with rewards accrued transparently on-chain.
This extends BIM’s existing yield optimization framework to Stellar-native assets and supports liquidity retention within the Stellar ecosystem.
Ecosystem Impact
The integration will:
Increase exposure of Stellar-native liquidity to multi-chain users
Generate measurable swap volume on Stellar
Enable staking participation and yield activity on Stellar
Provide fully verifiable on-chain metrics tied to real usage
All Stellar-related activity remains transparent and independently measurable on-chain.
Strategic Alignment with Stellar
The integration is designed to position Stellar as a liquidity destination rather than a transient routing layer. By combining native swaps and staking via Soroban smart contracts, BIM Exchange encourages sustained capital deployment within the Stellar ecosystem, increasing measurable TVL and long-term on-chain activity.
Bridged assets are intended to be actively deployed into Stellar-native swap and staking strategies rather than routed out of the ecosystem, reinforcing Stellar’s role as an execution and yield environment within BIM’s broader infrastructure.
Stellar Proof of Concept
A live Stellar proof of concept is available at:
https://exchange.bim.finance/poc/stellar
The POC demonstrates wallet connectivity and early Soroban-based swap functionality within the BIM Exchange interface.
$107.7K
BIM Exchange is a live DeFi protocol with measurable on-chain traction across supported networks.
Total Value Locked (TVL): ~$525k (ATH at $970k November, 1st 2025)
Active vaults: 20
Supported chains: 6 (Base, Plasma, Gnosis, Polygon, Ethereum, Optimism)
Total users: 160
All metrics are independently verifiable:
Liquidity growth has been driven through organic usage and structured on-chain incentive programs (via Merkl), demonstrating the protocol’s ability to attract and retain capital within supported ecosystems.
All performance data is fully transparent and measurable on-chain.
Budget: 6,300 USD
Description:
Integration of Stellar Wallet Kits into the BIM Exchange frontend, enabling users to connect a Soroban-compatible Stellar wallet and interact with Stellar-based functionality within the existing BIM architecture. This includes wallet connection, account detection, balance display, and transaction signing capability.
How to measure completion:
Stellar Wallet Kits successfully integrated in the BIM Exchange frontend
Users can connect and disconnect a Stellar wallet
Stellar account address and balances displayed correctly
Users can sign a Soroban transaction via the interface (testnet)
Successful interaction verifiable on Stellar testnet explorer
Estimated date of completion: 1 week after grant approval
Deliverable 2: Stellar Swap Execution Integration (Soroswap – Soroban)
Budget: 14,600 USD
Description:
Integration of Soroswap smart contracts deployed on Soroban into BIM Exchange’s routing and execution layer, enabling native swap execution on Stellar. The integration connects BIM’s orchestration layer to Soroban RPC endpoints to build, simulate, sign, and broadcast swap transactions.
How to measure completion:
Soroswap contracts integrated via Soroban RPC
Swap quote generation operational
Transaction simulation performed prior to execution
Successful swap transactions executed on Stellar testnet
At least three verified on-chain swap transactions publicly viewable
Deployment to Stellar mainnet
Estimated date of completion: 3 weeks after grant approval
Deliverable 3: Production Swap Interface (Frontend Integration)
Budget: 5,200 USD
Description:
Deployment of a production-ready Stellar Swap Interface integrated into BIM Exchange, aligned with existing UX patterns and connected to the live Soroswap execution layer. The interface allows users to select Stellar-native tokens, retrieve real-time quotes, preview execution parameters, connect a wallet, sign transactions, and view transaction status and confirmation.
How to measure completion:
Swap interface accessible on production frontend
Fully functional swap flow (wallet → quote → sign → broadcast → confirmation)
Live swap successfully executed on Stellar mainnet
UI displays transaction hash and confirmation status
Estimated date of completion: 4 weeks after grant approval
Budget: 31,400 USD
Description:
Integration of a cross-chain bridge provider enabling asset transfers from supported EVM networks into the Stellar ecosystem through BIM Exchange’s orchestration layer. The implementation includes routing logic, transaction lifecycle tracking, and settlement verification to ensure reliable EVM → Stellar transfers.
Once settled on Stellar, bridged assets can be immediately deployed within BIM Exchange for Stellar-native swaps (via Soroswap) and staking (via Defindex).
How to measure completion:
Integration of a bridge provider enabling EVM → Stellar transfers
Successful end-to-end bridge execution from at least one supported EVM network (testnet → mainnet)
Bridge transaction lifecycle observable (submission, confirmation, settlement)
Bridged assets successfully received on Stellar and visible in user wallet
Bridged assets usable in Stellar-native swap functionality
Estimated date of completion: 7 weeks after grant approval
Deliverable 5: Cross-Chain Frontend Integration
Budget: 11,300 USD
Description:
Implementation of a production-ready cross-chain user interface enabling users to initiate and monitor bridge transactions from supported EVM networks into Stellar.
The interface will clearly display source chain, destination chain (Stellar), estimated fees, estimated settlement time, and real-time execution status.
How to measure completion:
Bridge UI accessible in production
