# Proposal to upgrade the ckETH minter canister

Upgrade args hash: `5214320100ecc794582e8d3fcfcae6b42e66f0fd16bb81d21c8ef202f7215966`

Target canister: `sv3dd-oaaaa-aaaar-qacoa-cai`

Previous ckETH minter proposal: https://dashboard.internetcomputer.org/proposal/139665

---

## Motivation

Update the ckETH minter canister to include the latest code changes:

* Reduce the minimum ETH withdrawal amount by a factor of 6, from 0.03 ETH (`30_000_000_000_000_000` wei) to 0.005 ETH (`5_000_000_000_000_000` wei) — approximately $10 at current prices. The reasoning is as follows:
    * The current minimum dates back to December 2023, when the ckETH minter was installed (see proposal [126171](https://dashboard.internetcomputer.org/proposal/126171)). At that time ETH traded in a similar USD range (around $2000), but Ethereum mainnet transaction fees were averaging $5–$10 per transaction ([source](https://bitinfocharts.com/comparison/ethereum-transactionfees.html#3y)).
    * Today, Ethereum mainnet fees are in the order of cents and rarely exceed $1.
    * As explained [here](https://github.com/dfinity/ic/blob/14382b5abb14b8e7de2bd4a3fb402ba069b82861/rs/ethereum/cketh/docs/cketh.adoc?plain=1#L208), an order-of-magnitude safety margin is preserved so the minter can always submit the transaction even when the Ethereum network is congested and one or more resubmissions are needed (each resubmission requires at least a 10% fee bump). With current Ethereum fees of ~$0.10–$1, a $10 minimum still preserves the ~10× safety margin even after several fee bumps.
* Update the OFAC checklist.
