Interoperability with other smart-contract chains allows developers building on these platforms to leverage the unique permanent storage guarantees of Arweave. One such platform is Avalanche — a blazingly fast, low cost and eco-friendly smart contract chain.

Avalanche is one of the fastest smart contracts platforms in the blockchain industry, as measured by time-to-finality. Avalanche is also the premier platform for individuals and enterprises to easily create powerful, reliable, and secure private or public networks with complete control over their implementation. These “Subnets” can be the foundation for the creation of new ecosystems of value in asset tokenization and regulated institutional use cases.

We are pleased to announce that Arweave storage is now natively available on Avalanche.

Arweave continues to be the staple solution for permanent storage in web3 applications. Any decentralized applications requiring truly long-term (or permanent) storage should use Arweave to store arbitrary amounts of data in its current, immutable form and be guaranteed its persistence and availability for well beyond 200 years.

Users can now pay for permanent storage using Avalanche wallets and AVAX tokens. This opens a new design space for building truly decentralized applications on Avalanche, where everything from the UI to the smart contracts to the database is decentralized. Examples could include a full-stack decentralized social network, or an Avalanche version of Decentraland, only this time fully decentralized and immutable.

This interoperability is enabled by the Bundlr Network — which operates as an aggregator on top of Arweave by collecting many pieces of data and submitting them to the Arweave network in a single base-layer transaction. This allows the bundlr to offer custom payment options for its own users by paying to the Arweave network in AR, but settling with its users in a currency of their choice. Thanks to bundlr, the one-time payment required for uploading is now possible to make using AVAX.

If you have any permanent storage needs for your Avalanche application, you can now use this integration. Try building an app on avalanche today —, and store on Arweave using bundlr —
