Bundlers
Irys operates bundler nodes that accept signed DataItems and submit them to a destination network. Different nodes seed data to different destinations.
Note
The destination network is determined by the bundler node you connect to, not by the SDK or token used to pay. Pick the node that matches where you want your data to live.
Irys L1 Bundlers
These nodes seed uploads to the Irys L1.
| Endpoint | Network | Notes |
|---|---|---|
uploader.irys.xyz | Mainnet | Default bundler used by @irys/upload |
Arweave Bundlers
These nodes seed uploads to Arweave.
Warning
The Arweave bundler nodes are deprecated. New integrations should use the Irys L1 bundler above. Arweave bundler nodes will be shut down some time after the 1st of November, 2026.
| Endpoint | Network | Notes |
|---|---|---|
node1.irys.xyzmainnet.arweave.irys.xyz | Arweave Mainnet | Use for Arweave-specific uploads |
Devnet Bundlers
These nodes accept uploads paid with free faucet tokens for testing. Data is retained for approximately 60 days before deletion.
