Chainstack Builders Club

Infrastructure credits

$1,000 in Chainstack credits on your account, with no expiry date. They draw down against your invoices automatically, so there is nothing to redeem and no codes to enter.

Billing stays simple: one request unit per request, no method multipliers, and overage instead of hard cutoffs. When the credits land, a Chainstack engineer walks you through endpoints, archive data, and migration.

Marketing support

A customer story on chainstack.com, amplification on Chainstack's social channels, and co-marketing at the events we sponsor. Opt-in, and agreed with you first.

Ecosystem visibility

Introductions to the programs, partners, and ecosystem teams we already work with, wherever there is a fit for your chain and your use case.

Where Chainstack already backs founders

When we planned Agents on Open Rails, we wanted builders to spend their time on agents, not on infrastructure. Chainstack covered that side of the hackathon: every registered team got three months of the Growth plan, and Chainstack added their RPC to buy, our agent service marketplace, which makes access to their service even easier for agents.

On our Build with buy livestream they walked builders through how to use it, and for a week Chainstack was the most used service on buy. Builders also had someone to ask whenever they hit an RPC question.

That is the kind of partner you want behind a hackathon on live mainnet rails, which is built for long-term builders scaling real products.

Chainstack was our RPC partner for both pitch competitions we hosted with Arbitrum, in Berlin in June and in Singapore during TOKEN2049.

They supported the winning startups with infrastructure for their first year, providing real business value, not just swag. That's the kind of practical support that matters when founders are getting their startups off the ground.

Builders Club questions

What is Chainstack Builders Club?

A program for early-stage web3 teams. Accepted startups get Chainstack infrastructure credits applied to a paid plan, an onboarding session with a Chainstack engineer, and ecosystem visibility and introductions where there is a fit.

Who is eligible?

Teams that have not raised a Series A, have a working prototype, testnet deployment, or live product, and are building on a network Chainstack supports. Existing customers on the Developer or Growth plan can apply. Teams that already redeemed Chainstack credits are not eligible for a second grant.

How much credit do I get?

Every accepted team gets $1,000 in Chainstack credits with no expiry date, confirmed in your acceptance email. Credits apply to paid plans and are drawn down against your monthly invoices automatically, so you can spend them over several months or in a single launch.

Which chains are covered?

Every network Chainstack supports, including Ethereum, Solana, Base, BNB Smart Chain, Arbitrum, Celo, Polygon, Hyperliquid, TON, TRON, Sui, and 70+ others. Credits apply to Global Nodes on paid plans; Dedicated Nodes are available from the Pro plan.

Can I apply if I am already on Chainstack?

Yes. Teams on the free Developer plan or the Growth plan can apply. Credits are applied to your existing organization, so you keep your projects, endpoints, and keys.

What happens when the credits run out?

You stay on the same plan and move to standard billing: 1 request unit per request, with overage instead of hard cutoffs. Teams spending over $1,000 a month can move to Pay As You Go, with overage from $2.50 per million request units.

Can accelerators, VCs, or ecosystem programs refer teams?

Yes. Programs and funds can refer their portfolio companies, and can set up a dedicated track for a cohort, the way DeFi Founders Club and the Agents on Open Rails hackathon did. Use the partner contact above to start that conversation.

How long does the review take?

Most applications are reviewed within a few business days. If the fit is clear, you get an acceptance email with your credit amount and a link to book your onboarding session.
