HEI

Historical Exchange Index

A quiet registry of crypto exchanges, active and gone.

Donate

Support HEI

HEI includes a public support page for people who want to help maintain and expand the registry. Donation support is optional, but it can help sustain the slow work of record building, cleanup, archive checks, and record verification.

What donations support

Record expansion
Adding more entities, events, and evidence across active-side and dead-side entries.
Archive coverage
Improving archived URL coverage and safer historical linking.
Verification work
Reviewing dates, causes, and classification details where records remain uncertain.
Maintenance
Keeping the public registry readable, usable, and up to date over time.

Wallet addresses

Send only the named asset on the listed network. Double-check address and network before sending. Wallet cards below include a copy button for each address.

Notes

Network caution
Do not send assets on the wrong network. Funds sent on unsupported networks may be lost.
XRP note
No destination tag is listed on this page. Confirm your sending service can send without one before using the XRP address.
Final check
Always verify the copied address on your own device before submitting a transaction.
Support is optional. HEI is intended to remain usable as a public registry regardless of whether you donate.
