Community funding

Fund this canister

no community top-ups yet

This canister is running with a healthy balance. Balance 196.3 T, idle burn 146 B/day.

Top-ups cannot be refunded or withdrawn, by you, by ICPWatch, or by anyone else. The cycles belong to the canister.

Revive: enough to bring it above the freezing threshold and running again. A revived canister burns at its normal rate again, so it needs a controller or a community that keeps funding it.

This canister is running and is not at risk right now. A top-up simply extends its runway.

This is the canister's own top-up account on the Cycles Minting Canister, not an ICPWatch address. The memo is what tells the CMC which canister to credit: a transfer without it is refunded automatically by the CMC (minus the ledger fee), so exchanges that cannot set a memo will not work. Once ICP lands, ICPWatch asks the CMC to convert it; nothing else is needed.

Waiting: the account is checked every few minutes for a day after you click.

Non-custodial and non-refundable: ICP goes to the canister through the CMC and becomes that canister's cycles. ICPWatch never holds it and cannot reverse it. Anyone may top up any canister; that is how the Internet Computer works. Top-ups appear in the public record below once the CMC has credited them.
