Wind down the Dogecoin integration and ckDOGE

What this motion proposes

This motion proposes an orderly retirement of the Internet Computer's Dogecoin integration (the Dogecoin canister and adapter) and of the ckDOGE token (minter and ledger suite). ckDOGE holders get three months to redeem their ckDOGE for DOGE. After that, the DFINITY Foundation holds the remaining DOGE so that holders who missed the window can still claim it.

Background

The Dogecoin integration gives canisters access to the Dogecoin network. ckDOGE is a chain-key token backed 1:1 by DOGE held by the ckDOGE minter. Together they add four components that must be maintained, upgraded, monitored and secured:

• the Dogecoin canister
• the Dogecoin adapter
• the ckDOGE minter
• the ckDOGE ledger suite

Usage is minimal. At the time of writing, the total ckDOGE supply is 1,496 ckDOGE, about $150.

Rationale

• Focus. Engineering capacity for chain-fusion work is limited and is best spent on the integrations people use. Keeping the Dogecoin integration running competes directly with those priorities.
• Security surface. Every integration that holds user assets has to meet the highest security bar. Retiring one that is barely used lowers risk for the whole ecosystem.
• Honest commitments. A component that holds user funds should either be maintained properly or retired properly. An orderly retirement serves users better than slow neglect.

Wind-down plan

1. Announcement. A forum post is published together with this motion.
2. Stop new deposits. After this motion is adopted, an upgrade proposal disables ckDOGE minting. DOGE sent to a ckDOGE deposit address after that point is not credited.
3. Withdrawal window (3 months). ckDOGE → DOGE withdrawals stay open for three months after minting is disabled.
4. Snapshot and custody. At the end of the window, a snapshot of the ckDOGE ledger is taken and published, and an upgrade proposal moves the remaining DOGE backing from the minter to a wallet held by the DFINITY Foundation.
5. Claims (12 months). Anyone who can show they control a principal with a balance in the snapshot can claim the matching DOGE from the Foundation for 12 months after the snapshot.
6. Retirement. Further proposals then stop the ckDOGE minter, the ckDOGE ledger suite, the Dogecoin canister and the Dogecoin adapter.

Impact on developers

We are not aware of any canister that calls the Dogecoin canister API directly. Developers of such canisters should comment on the forum thread linked above.

What this motion does not do

Adopting this motion does not change any code or canister by itself. Each step above that touches a canister is carried out by a separate proposal that the NNS votes on.
