Join the private beta

Be first to experience a new era in web3 serverless functions with on-chain storage.

Simplify your development process, eliminate infra management, and focus on shipping dApps

Go beyond the limits of smart contracts

Plug in data from your app or any chain

Integrate any web2 or web3 data source with deterministicFetch(). MEM breaks your app free from blockchain siloes, without expensive oracles.

Interact via API or SDK

Integrating MEM into a dApp front end is as simple as it gets. Read from and write to function state over API, or use the powerful SDK.

Compatible with 14 chains

Verify any identity or on-chain action across 14 chains. MEM functions can be deployed alongside existing dApps as a web2-compatible execution layer.

What is MEM?

Built on a new paradigm

Compute off-chain, store on-chain. Leave scaling challenges behind without sacrificing tranparency and trustless verifiability.

MEM is stateful

MEM function states are onchain, producing an immutable record and guaranteeing data availability.

MEM is chain-agnostic

Use powerful web3 primitives without the ecosystem lock-in.

Integrate any data or API

No more siloes! Use deterministicFetch() to interact with any API, oracle, or onchain data source.

Why MEM?

Compute you can rely on

MEM is highly deterministic. Functions mitigate unpredictable behaviour by preventing non-deterministic states, even for potentially malicious code.

Forget paying for storage and servers

MEM is a fully managed scalable environment, enabling you to focus solely on code while we handle the infrastructure. No need to provision servers, manage databases or worry about data persistence

Endless use cases

DIDs, key-value store, content publishing, noSQL databases, token-gating, action verification. On-chain state, lightning-fast, and trustlessly verifiable.

How Much Does MEM Cost?

MEM is currently free to use.

Why MEM?

MEM is perfect for developers who need to scaffold an immediate, massively-scalable server app with a permanent, cheap database. Aside from a swift and smooth bootstrapping experience, MEM is also great for developers who want to make crosschain dApps with ease.

Which Chains Does MEM Support?

MEM supports all chains with EVM-based signatures, for example, Ethereum, Polygon, Optimism, BSC. Non-EVM chains include Solana, Aptos, Tezos, Tron, Zilliqa, Stacks, Arweave, Telegram Open Network, Massa, Internet Computer, Substrate, Nostr, and Fuel.
