Blockchain technology, once riding the wave of intense hype, has settled into a more pragmatic phase. While public interest may have cooled since its peak, the underlying innovation continues to mature—especially in enterprise applications where trust, transparency, and data integrity are paramount.
Enterprises today demand robust integration between legacy systems and emerging technologies. One powerful solution comes from InterSystems IRIS, a high-performance data platform that now supports direct interaction with the Ethereum blockchain through its dedicated outbound adapter. This integration opens new doors for organizations seeking to leverage decentralized networks without overhauling existing infrastructure.
In this article, we’ll explore how the InterSystems IRIS Ethereum adapter enables seamless communication between enterprise-grade applications and the Ethereum network, covering architecture, use cases, setup steps, and practical deployment examples—all while optimizing for security, scalability, and maintainability.

Understanding Blockchain in Enterprise Context
Before diving into technical details, it's important to clarify when blockchain truly adds value. Despite early overpromises, blockchain isn’t a universal fix—it shines in specific scenarios:
- Multiple parties need access to a shared, tamper-proof ledger.
- There is no central authority trusted by all participants.
- Data immutability and auditability are critical (e.g., healthcare records, supply chain logs).
- Transactions must be verifiable without intermediaries.
Industries like healthcare, pharmaceuticals, and clinical research stand to benefit significantly. For example:
- Secure, decentralized patient record management
- End-to-end tracking of drug shipments to prevent counterfeiting
- Transparent and auditable clinical trial data logging
For these applications, enterprises often opt for private or permissioned blockchains. However, public blockchains like Ethereum remain relevant due to their openness, maturity, and vast developer ecosystem.
Ethereum, in particular, offers smart contract functionality—self-executing agreements coded directly on the blockchain—making it ideal for automating complex business logic across untrusted parties.
What Is the InterSystems IRIS Ethereum Adapter?
The InterSystems IRIS Ethereum adapter is an outbound interoperability component that allows IRIS-based applications to interact with the Ethereum network. Unlike generic APIs, this adapter is built into the InterSystems IRIS integration framework, enabling native connectivity within production-grade health, finance, and logistics systems.
Key Features
- Deploy Ethereum smart contracts directly from IRIS
- Invoke both state-changing and read-only smart contract methods
- Transfer Ether between wallets
- Query blockchain state (e.g., balance, transaction status)
- Log all requests via integrated Node.js module for debugging
- Support for testnets (e.g., Ropsten) and mainnet
This adapter extends IRIS’s already strong interoperability model—traditionally used for HL7, FHIR, REST, and SQL integrations—into the decentralized world.
Architecture Overview
The adapter uses a hybrid approach combining InterSystems IRIS with a lightweight Node.js middleware module. This design leverages well-established Ethereum libraries such as Web3.js or Ethers.js while keeping core logic within the secure IRIS environment.
Here’s how it works:
- An IRIS business operation triggers a request (e.g., deploy contract).
- The request is passed to the Node.js module running on a specified server/port (default: 3000).
- The Node.js layer communicates with Ethereum via Infura or a local Geth node.
- Responses (e.g., transaction hash) are returned to IRIS for processing or logging.
Credentials—like wallet addresses and private keys—are securely stored in an encrypted IRIS database. Never exposed in plain text, they ensure compliance with enterprise security standards.
Getting Started: A Step-by-Step Guide
To begin using the Ethereum adapter, follow these steps:
1. Choose Your Network
For development and testing, use a testnet like Ropsten, Goerli, or Sepolia. These networks allow you to experiment without spending real Ether.
👉 Learn how developers test blockchain integrations safely before going live.
2. Set Up a Wallet
Create an Ethereum wallet using tools like MetaMask. Fund it with testnet ETH from a faucet (e.g., https://faucet.quicknode.com).
Store your wallet’s public address (username) and private key (password) securely. These will be used in IRIS configuration.
3. Connect to Ethereum
You have two options:
- Run a local Ethereum client like Geth
- Use a cloud provider like Infura or Alchemy (recommended for simplicity)
With Infura, create a project and obtain your endpoint URL (e.g., https://ropsten.infura.io/v3/YOUR_PROJECT_ID).
4. Configure the Business Operation
In InterSystems IRIS Management Portal:
- Set the Node.js server address and port
- Enter provider URL (Infura endpoint)
- Add credentials: wallet address as username, private key as password
- Enable encryption for credential storage
5. Prepare Smart Contract Files
For each smart contract you want to use:
- Create a folder in the file system
Place two files inside:
abi.txt– Application Binary Interface (JSON format)bytecode.txt– Compiled contract code (used only for deployment)
These are generated during compilation using tools like Solidity compiler (solc), Remix IDE, or Truffle.
Practical Example: Deploying and Interacting With a Smart Contract
Let’s walk through deploying a simple "Hello World" smart contract and invoking its methods.
Deploying the Contract
Use the IRIS interoperability test service to trigger deployment:
Set tRequest = ##class(Ethereum.Request).%New()
Set tRequest.Action = "deploy"
Do ..AdapterOperation.SendRequestSync(tRequest, .tResponse)
Write tResponse.TransactionHashUpon success, you’ll receive a transaction hash. Look it up on etherscan.io to confirm deployment and retrieve the contract address.
Calling Read-Only Methods
Once deployed, call non-state-changing functions synchronously:
Set contract = ..Adapter.GetContract("ContractAddress", "ABI")
Set result = contract.hello()
Write result ; Outputs: "Hello from Ethereum!"No gas cost or confirmation delay—ideal for queries.
Invoking State-Changing Methods
Methods that alter blockchain state (e.g., updating variables) require gas and time to confirm. Use deferred response mechanism:
Set tRequest = ##class(Ethereum.Request).%New()
Set tRequest.Action = "invoke"
Set tRequest.Method = "setName"
Set tRequest.Params = ["NewName"]
Set tRequest.DeferredResponseToken = "TOKEN_123"
Do ..AdapterOperation.SendRequestAsync(tRequest)Configure a web application and business service to receive callbacks when the transaction is confirmed.

A: Yes. The adapter works with any Ethereum-compatible network—including private chains—as long as you provide a valid JSON-RPC endpoint.
Q: Is the source code available?
A: Yes. The adapter is open-sourced on InterSystems Open Exchange: Ethereum Interoperability Adapter.
Q: How is security handled for private keys?
A: Private keys are never stored in plaintext. They’re kept in an encrypted credentials database within IRIS, following enterprise security best practices.
Q: Does this work with other blockchains?
A: Currently designed for Ethereum. However, similar patterns can be applied to other EVM-compatible chains like Polygon or Binance Smart Chain.
Q: What happens if a transaction fails?
