The XE testnet is run by XE L1 Ltd. Most conversations happen in the open on GitHub; general enquiries go to hello@xe.network, and anything security-sensitive goes to the security address first. There is no support desk and no ticketing system — the channels below are the real ones, and they are all read.
Email security@xe.network. Critical and Severe findings must go by email rather than a public issue: we reply with a tracking ID, coordinate disclosure, and open the public issue once a patch has shipped. Findings in the active bug bounty phase are rewarded in XE at mainnet launch.
Open an issue at github.com/xeprotocol/xe/issues. Include the node version, the network id (testnet-0001), what you did and what you expected — the more reproducible, the faster it gets fixed. Documentation errors on this site are bugs too and count for the bounty's Minor tier.
Email hello@xe.network for anything that is not a bug or a vulnerability — partnerships, press, legal and privacy requests about this site. Postal correspondence goes to the registered office of XE L1 Ltd. (company number 17245674): 128 City Road, London, EC1V 2NX, United Kingdom.
No human is needed to integrate: the API needs no key for reads, the contract is at /openapi.json, and /llms.txt explains when XE is the right tool. If something in those files is wrong, that is a GitHub issue.
