The decentralized finance (DeFi) landscape continues to evolve at a rapid pace, with innovation driving new levels of efficiency, accessibility, and integration across blockchain ecosystems. In this edition of DeFi Connect, we explore the latest advancements from Expand.network — a leading API infrastructure platform empowering developers, traders, and institutions to scale seamlessly across Web3.
A Message from Our CEO
From the heart of a bustling spring season filled with global travel and industry engagement, Demetrios Skalkotos, Co-Founder and CEO at Expand.network, shares insights from recent experiences — including a standout trip to Dubai.
Despite unforeseen weather disruptions, the reception to Expand’s API was overwhelmingly positive. Interest from traders, developers, and ecosystem builders reaffirmed a growing need for robust, reliable API infrastructure in DeFi.
"Traders are increasingly adopting our DEX aggregation API to minimize latency, reduce transaction fees, avoid failures, and lower counterparty risk — all while maximizing returns."
Whether you're building a multi-chain application or optimizing trading strategies, Expand's unified API streamlines access to full price discovery and superior trade execution across the DeFi ecosystem. Best of all? It saves countless developer hours.
👉 Discover how you can accelerate your DeFi integration with powerful API tools.
✨ New Features: Powering Developer Efficiency
Expand.network continues to enhance its API suite with features designed for performance, accuracy, and ease of use.
Gas Fee Estimation
Now available for EVM-compatible chains, this feature allows developers to retrieve accurate gas estimates before executing transactions. This helps prevent failed transactions due to insufficient gas and improves cost forecasting — especially critical during periods of network congestion.
Approve & Swap in a Single Call
A major step forward in transaction efficiency: Expand SDK now supports batched approval and swap operations through one unified call. This eliminates the need for two separate requests — reducing latency, complexity, and user friction.
Ideal for high-frequency trading bots and automated strategies, this feature accelerates execution speed and enhances reliability.
Enhanced Historical Block Data
The /getblock endpoint has been upgraded with deeper data parameters:
logsBloom- Logs per transaction
yParitymaxFeePerGasmaxPriorityFeePerGas
These additions empower data aggregators and analytics platforms to efficiently verify log content without parsing each entry individually — enabling faster, more granular on-chain analysis over custom block ranges.
Token Market Data Endpoint
Access comprehensive market intelligence for any token via a single endpoint. Retrieve real-time data including:
- Market capitalization
- Total, circulating, burned, and future supply
- All-time high and low prices
This feature is invaluable for portfolio trackers, dashboards, and investment research tools looking to integrate authoritative token metrics.
✨ Spotlight: Seamless Integration with TON Ecosystem
For several months, Expand.network has been deepening connectivity with The Open Network (TON) Foundation ecosystem. Through strategic protocol integrations and partnerships with key projects, Expand now offers a unified API gateway for developers building on TON.
This integration unlocks two major benefits:
- Accelerated development of multi-chain applications
- Plug-and-play onboarding for teams entering the TON ecosystem
With seamless access to transactions, data sourcing, and smart contract interactions, developers can focus on innovation rather than infrastructure.
Are you building on TON? Let Expand simplify your integration journey.

✨ New Integrations: Expanding Chain & Protocol Support
To support broader ecosystem interoperability, Expand has added support for several major chains and protocols:
Lido V2
Fully interact with Lido’s next-gen liquid staking protocol:
- Stake and unstake ETH
- Approve and request withdrawals
- Wrap and unwrap stETH
- Query protocol data
All actions are accessible via simple API calls — ideal for yield aggregators and institutional staking platforms.
Stellar Blockchain
Now integrated into Expand’s non-EVM chain support, Stellar enables:
- On-chain transaction execution
- Real-time data sourcing
- Developer tooling for financial applications
Perfect for projects focused on payments, remittances, or asset tokenization.
ORCA (Solana)
As Solana’s leading DEX, ORCA brings high-speed swaps and liquidity provisioning to Expand’s aggregation layer. Developers can now:
- Swap tokens instantly
- Add or remove liquidity
- Fetch pool and price data
With Solana’s growing DeFi momentum, this integration ensures access to one of the fastest-growing ecosystems.
Coming Soon
Expand is actively working on support for:
- Bitcoin
- Ripple (XRP)
- Internet Computer (ICP)
- Cosmos
- Raydium
- Jupiter
Stay tuned for announcements as these integrations go live.
