GetBlock March 2026 Dev Update: Sui gRPC, Token Risks API, Backbone Infra Upgrades

Hey folks! March was a busy one for GetBlock.

A lot of things landed: a new API product, a big backend upgrade finally in production, Sui gRPC added, a refreshed support flow, and a handful of smaller things. Here’s a quick recap.

GetBlock March 2026 updates – TL;DR

And we can’t leave you without juicy details. Read on for the full rundown

GetBlock now supports Sui gRPC

Sui is deprecating its JSON-RPC interface, with a hard deadline of July 31, 2026. In March, we added full production-ready Sui gRPC support at GetBlock so builders can continue using the network without disruptions as the ecosystem moves forward.

What's included:

We’ve also updated our Sui docs to help you get started, including a TypeScript and Node.js setup guide and a list of available Sui gRPC methods. The detailed API reference will arrive soon.

If you're still on JSON-RPC, nothing breaks today. Sui JSON-RPC interface remains fully supported for as long as possible. But to stay future-proof, it’s a good time to start moving to gRPC before the deadline.

Token Risks API brings smart contract security checks to GetBlock

We launched a new product in March: Token Risks API. This is a smart contract risk analysis tool available via API and as an online scanner.

GetBlock’s Token Risks API scans EVM smart contracts, including ERC-20 token contracts, across 29 supported chains, such as Ethereum, BNB Chain, Base, Polygon, Arbitrum, Optimism, Celo, Unichain, and Berachain.

How it works:

The contract is analyzed through over 20 risk patterns, including unusual owner control, approvals, upgrade logic, external calls, hidden functions, blacklist or whitelist restrictions, ERC-20 standard compliance, and more.

For developers, the API returns structured JSON that can be easily integrated into wallets, dashboards, analytics pipelines, or internal security tools.

See it in action – try the online scanner for a quick check. Request API access if you need smart contract risk monitoring and onchain intelligence at scale.

Singapore cluster: Nomad to Kubernetes migration complete

In March, we completed the full migration of our AP-Southeast cluster orchestration layer – from Nomad to Kubernetes.

If you route traffic through GetBlock’s Singapore-based nodes, this upgrade brings:

A bit of context:

As our infrastructure grew more complex, Nomad started to require more custom workarounds, especially for stateful services and large-scale coordination. Kubernetes gives us a more modern, flexible foundation that scales better and a more unified architecture overall: 

This was a long and complex project, but it gives us a much stronger infrastructure foundation going forward. New York and Frankfurt cluster will follow.

Changes to Free plan

We’ve made a small tweak to GetBlock’s free plan: a few resource-heavy endpoints that were previously available on the free tier now belong to the Starter tier and above.

Free plan users can still build freely on all major networks. Access is limited to dozens of protocols, including Monad, Celo, HyperEVM, IOTA, Atleta, Botanix, Xai, and others. Some network and region configurations for these protocols are now available on more powerful tiers starting at $39/mo.

The update took effect on March 25, 2026. It doesn’t delete already created endpoints – everything keeps running.

This change helps us balance open access with stable performance. We’ve noticed our free plan’s been getting a workout lately – some endpoints consume more resources with less predictable traffic. By moving them to paid plans, we avoid misuse of heavy endpoints on Shared nodes and keep the performance stable across the service.

New support experience: Live messenger

We replaced the old Zendesk web widget with a live messenger available anywhere on the GetBlock website.

How it was: The old widget made you fill out a form, it created a ticket, you got an email chain.

What's different now: The new one is a live chat messenger. You see who you're talking to, when they're typing, replies are real-time. Ticket history is now directly in the chat.

It's a small change, but it noticeably closes the gap between asking a question and getting an answer.

Node client updates: Ethereum, Solana, BSC, Optimism & more

As always, we’ve been busy keeping GetBlock’s nodes up to date across all supported networks. Here are some of the high-impact releases of March:

All eyes on GetBlock’s YouTube

Over the past few months, we’ve been rebuilding our YouTube presence, and now it’s official. GetBlock's video production is in full swing.

We’re going all-in with a mix of content for Web3 builders:

Online sessions: March recap & April lineup

In the past month, we joined a few online sessions packed with insights.

March kicked off with a roundtable on how institutions adopt crypto in 2026. GetBlock's CCO, Roman Shtih, joined OQTACORE's team to unpack how financial institutions are adopting digital assets right now. The discussion went beyond buzzwords, touching on what actually works in practice and where they struggle.

A week later, our CTO, Nikita Iugov, joined the Simplify Labs webinar about blockchain infrastructure quality and its impact on business. Karym Abdelrakhman, CEO of Simplify Labs, broke down what poor infrastructure really costs in lost time and trust. Nikita showed what’s happening under the hood and how to measure infrastructure performance properly. Catch the recording on YouTube.

Coming up: We’re going hands‑on with real‑time blockchain data in a live workshop for Solana builders and traders. Mark your calendar for April 15.

Building a Solana NFT Indexer with Yellowstone gRPC

Our guest expert will dive into Solana Yellowstone gRPC, a blazing‑fast streaming setup used by pro‑level trading systems and analytics engines that can’t afford a single millisecond delay.

You’ll see what the hype around gRPC is really about and walk away with a working NFT indexer. Expect code, demos, and plenty of "aha!" moments.
