xmtp-node-go

This repo provides software for the nodes that currently form the XMTP network. No new development is planned for this node software.

At this time, all nodes in the XMTP network are run by XMTP Labs, whose mission is to promote and support the development and global adoption of XMTP.

All new development is focused on xmtpd, an experimental version of XMTP node software.

After xmtpd meets specific functional requirements, the plan is for it to become the node software that powers the XMTP network. In the future, anyone will be able to run an xmtpd node that participates in the XMTP network.

Deployments

Merging a PR to the main branch will trigger a new deployment via GitHub Actions and Terraform.

The default behavior is to deploy main to both the dev and production environments. If you'd like to deploy a different branch to dev, open a PR with an update to .github/workflows/deploy.yml switching from main to your branch. Remember to PR it back to main when you're done.

Changes will be automatically applied and no user action is required after merging.
