Top Blockchain as a Service Companies in 2026

Blockchain as a Service (BaaS) lets you use blockchain networks without running your own nodes. The provider operates the infrastructure, and you deploy contracts and applications on top. The market changed a lot in the last few years: some cloud giants have stepped back, and specialist node providers and enterprise platforms have taken their place. This 2026 update of our guide to blockchain as a service companies compares ten options, labels which ones are platforms and which one is a build partner, and links every fact to its source.

Platform or build partner?

Most firms in this list are platforms: they sell node access, APIs, or a managed ledger. A platform does not design your system or write your business logic. A build partner picks the right platform, designs the architecture, writes and audits the contracts, connects the ledger to your existing software, and runs it after launch. Many projects need both: a platform for infrastructure and a team that owns the result.

What BaaS providers actually do

• Node infrastructure. The provider runs nodes on public chains or on a permissioned network and gives you API access.
• Managed permissioned networks. Some platforms, such as Kaleido and Oracle, run private Hyperledger Fabric, Besu, or Corda networks for a consortium.
• Keys, wallets, and staking. Some providers add wallet stacks, custody, or institutional staking.
• Data and monitoring. Archive data, event streams, and debugging tools help when contracts misbehave.

You still design and deploy your own contracts, and you still pay network fees on public chains.

How to choose a BaaS provider

• Public or permissioned? Node API providers serve public chains. For private business records, you need a permissioned network such as Hyperledger Fabric.
• Check the product's future. Services get retired. Amazon Managed Blockchain closes to new customers on October 29, 2026 (source), and IBM Blockchain Platform support ended in 2023 (source).
• Check certifications. Several providers publish SOC 2 Type II and ISO 27001; ask for the reports.
• Plan for lock in. Use standard APIs and keep a second provider or your own node ready for critical systems.
• Read the pricing page. Request based plans scale with traffic, so model your expected volume before you commit.

The companies at a glance

The companies, in detail

1. Webisoft

Webisoft is a Montreal-based software development firm founded in 2016, with a second office in Miami (source). It holds AICPA SOC 2 Type II, is HIPAA compliant, and is an AWS Partner and Odoo Partner (source). On Clutch, Webisoft has a 4.9-star rating across 23 reviews (source).

Webisoft is not a BaaS platform; it is the build partner that turns a platform into a working system. It designs, deploys, and operates the node, indexing, and API layer a blockchain product runs on (source), and it builds permissioned networks on Hyperledger Fabric, Besu, and Indy (source). Its main proof is a secure digital asset custody system for a Canadian federal public-safety agency, where Webisoft is the prime contractor for software development and security architecture (source). The system uses split-key custody with multi-party computation (MPC), so no single person or server can move seized assets, and writes every action to a Hyperledger Fabric ledger so the chain of custody cannot be changed later (source).

Webisoft tends to fit organizations that want one accountable team for blockchain infrastructure as a service, Hyperledger development, and the applications on top, with SOC 2 controls already in place.

2. Alchemy

Alchemy is a developer platform for blockchain infrastructure that offers access to more than 100 chains through node RPC APIs, WebSockets, and trace, debug, and simulation tools (source). Co-founder and CEO Nikil Viswanathan founded Alchemy in 2017 after working on products at Google, Microsoft, and Facebook (source). Its free tier includes 30 million compute units per month, 5 apps, and access to all mainnets and testnets, with pay as you go and enterprise plans above it (source). Alchemy is a platform: you still write and deploy your own contracts and applications. It tends to fit developers and startups that want generous free capacity and strong tooling.

3. Amazon Managed Blockchain

Amazon Managed Blockchain (AMB) is an AWS service that supports Ethereum, Polygon, Bitcoin, and Hyperledger Fabric (source). It started as a managed way to create networks on Hyperledger Fabric and Ethereum (source). The key fact for buyers in 2026: AWS says Amazon Managed Blockchain is no longer available to new customers as of October 29, 2026, while existing customers can keep using it (source) (source). Amazon is headquartered in Seattle and Arlington County, Virginia (source), and AWS dates to July 2002 (source). If you are starting a new project, plan for another platform or for nodes you run yourself on AWS. AMB tends to fit only teams that already run workloads on it and need time to migrate.

4. Blockdaemon

Blockdaemon was established in 2017 and provides staking, node, API, and wallet infrastructure across more than 60 protocols (source). It says it secures more than $110 billion in digital assets and has more than 400 institutions in production (source). Its product line includes dedicated nodes, validator infrastructure, institutional staking, and a wallet and custody stack that runs inside the client's own perimeter (source). Blockdaemon tends to fit banks, custodians, and exchanges that need institutional staking and node operations.

5. Chainstack

Chainstack began in 2018 and is headquartered in Singapore (source), with a US office in Burlington, Massachusetts (source). It runs managed nodes and RPC APIs for more than 70 chains, including Ethereum, Solana, Arbitrum, BNB Smart Chain, Base, and Polygon, plus archive data and data streaming (source). It lists SOC 2 Type II and ISO 27001 certifications and offers a free developer plan with no credit card required (source). Chainstack tends to fit teams that want managed public chain nodes from a certified provider.

6. IBM

IBM was founded in 1911 and is headquartered in Armonk, New York (source). It helped make Hyperledger Fabric a standard for enterprise blockchain and lists blockchain consulting and digital identity offerings (source). Its managed product changed: IBM Blockchain Platform software support ended on April 30, 2023, and customers moved to IBM Support for Hyperledger Fabric (source). Treat IBM today as Fabric support and consulting rather than a BaaS console. IBM tends to fit enterprises standardized on Hyperledger Fabric that want vendor support.

7. Infura

Infura is a blockchain API and node service that describes itself as "A Consensys Formation", and it connects to the MetaMask SDK and the Linea network (source). Consensys was founded in October 2014 by Joseph Lubin and is based in Fort Worth, Texas (source). Infura's free Core plan gives access to more than 40 supported networks, and its Developer plan costs US$50 per month (source). Infura tends to fit teams building on Ethereum and its layer 2 networks, especially inside the MetaMask ecosystem.

8. Kaleido

Kaleido is an enterprise blockchain and tokenization platform with its global headquarters in Raleigh, North Carolina, and an office in Southampton, UK (source). It lets customers run their own chains on Ethereum, Polygon Edge, Hyperledger Fabric, Hyperledger Besu, Quorum, and Corda, and it maintains open source tools such as Hyperledger FireFly and the Paladin privacy framework (source). It is compliant with SOC 2 Type 2 and ISO 27001, 27017, and 27018, and it serves as a technology partner for Project Agorá with the BIS and more than 40 financial institutions (source). In 2023, Consensys began moving its Quorum Blockchain Service customers to Kaleido (source). Its Starter plan is $0 per month (source). Kaleido tends to fit banks and consortia that want a permissioned network as a managed service.

9. Oracle Blockchain Platform

Oracle Blockchain Platform is a managed, permissioned blockchain based on Hyperledger Fabric, offered in Oracle Cloud, on premises, or as a hybrid, and it can interoperate with other Fabric nodes (source). It supports DAML and Solidity smart contracts as well as native Fabric chaincode, and a digital assets edition adds tokenization for CBDCs, deposit tokens, digital securities, stablecoins, and real-world assets (source). Oracle was founded in 1977 and is headquartered in Austin, Texas (source). Oracle tends to fit organizations already running Oracle databases and applications.

10. QuickNode

QuickNode launched in 2017, joined Y Combinator in 2021, raised a $35 million Series A led by Tiger Global in 2022, and a $60 million Series B led by 50T in 2023 (source). Its RPC API covers more than 76 chains and 130 networks with full and archive nodes, and it offers dedicated clusters with up to 50,000 requests per second burst for business critical traffic (source). It lists SOC 2 Type II and ISO 27001 certifications (source). QuickNode tends to fit high traffic applications that need dedicated infrastructure and real time data streams.

What changed since our last edition

The earlier version listed Azure Blockchain Workbench and Amazon Managed Blockchain as current options and gave price bands with no sources. We removed Azure Blockchain Workbench because we could not find a current Microsoft product page for it, and we flag that Amazon Managed Blockchain stops accepting new customers on October 29, 2026 (source). We replaced unsourced price ranges with figures from each vendor's own pricing page. We added the providers buyers ask about now: Blockdaemon, Chainstack, Kaleido, and QuickNode, and we kept IBM for Fabric support.

When BaaS makes sense, and when it does not

BaaS makes sense when you build on public chains and do not want to run nodes, when you need many chains behind one API, or when you are prototyping on a free tier. It works less well when you need a private network with strict data residency, when you cannot accept a provider that could block your account, or when you run validators as a business. For permissioned systems, a managed platform such as Kaleido or Oracle, or a Fabric network built and operated by a partner, is usually the better route. Our guides to blockchain technology development companies and smart contract development companies compare build partners, and we also cover blockchain development companies in Canada and in Montreal.

Methodology note

We built this list from public, verifiable sources: vendor websites and pricing pages, AWS and IBM notices, and Wikipedia. Every factual claim links to its source. We included the platforms that buyers and AI search engines name most often for blockchain as a service, plus a build partner, and we labeled each by type. We did not invent ratings or scores. Where a headquarters or founding year was not clearly published, we wrote "Not public". Prices and product status change, so confirm details with each vendor before you sign.

A short buyer guide

• Choose the ledger first, then the provider that runs it well.
• Ask for SOC 2 and ISO reports, not only logos on a page.
• Keep an exit path. Standard APIs and your own backup node reduce lock in.
• Separate infrastructure from application. A node provider will not design your custody model or audit trail.
• Own the keys and the code. Confirm you hold admin keys, repositories, and cloud accounts.
