## Proposal to Upgrade the Cycles Ledger Canister
##### Proposer: DFINITY Foundation
##### Repository: http://github.com/dfinity/cycles-ledger
##### Git Hash: `eff32e868b6b673698a442b6115338719d071100`
##### Compressed Wasm Hash: `d2aacbd214f20d752fd1696c2e36d7eceaafe07b932b3ae9e7e5564d1bda0178`
##### Argument Hex: `4449444c0000`
##### Target canister: `um5iw-rqaaa-aaaaq-qaaba-cai`

---

## Motivation

Update the cycles ledger canister to include the latest code changes:
* Adapted `icrc3_get_tip_certificate` to be compliant with the ICRC-3 specification by changing the encoding of `last_block_index` to `leb128`.

## Wasm Verification

```bash
git clone git@github.com:dfinity/cycles-ledger.git
cd cycles-ledger
git checkout eff32e868b6b673698a442b6115338719d071100
./scripts/docker-build
sha256sum cycles-ledger.wasm.gz
```

## Argument Verification

```bash
didc encode -f hex '()'
```

## Code changes

The current version of the cycles ledger was installed in proposal [132135](https://dashboard.internetcomputer.org/proposal/132135). The full code diff can be viewed [here](https://github.com/dfinity/cycles-ledger/compare/cycles-ledger-v1.0.1...cycles-ledger-v1.0.3).


Upgrade NNS Canister: um5iw-rqaaa-aaaaq-qaaba-cai to wasm with hash: d2aacbd214f20d752fd1696c2e36d7eceaafe07b932b3ae9e7e5564d1bda0178
