# Proposal to upgrade the EVM RPC canister

Repository: `https://github.com/dfinity/evm-rpc-canister.git`

Git hash: `32c067d3b19ccc91e3abd991f9c6c2204466021a`

New compressed Wasm hash: `c5517f9d69864f3ad285b8aa77c5af515a2caf7241b8765960e6259d2964e9f7`

Upgrade args hash: `6005397a2ddf2ee644ceaca123c9afbd2360f0644e7e5e6c4ac320a5f7bd4a82`

Target canister: `7hfb6-caaaa-aaaar-qadga-cai`

Previous EVM RPC proposal: https://dashboard.internetcomputer.org/proposal/139081

---

## Motivation

Upgrade the EVM RPC canister to the latest version [v2.7.0](https://github.com/dfinity/evm-rpc-canister/releases/tag/evm_rpc-v2.7.0),
which includes in particular the following changes:
* For each `eth_*` endpoint, add a new corresponding `eth_*CyclesCost` query endpoint with the same Candid arguments, that allows computing the cycles cost of calling the corresponding `eth_*` update endpoint.
* Use constant-size JSON-RPC request IDs for consistent request cost calculations.

See the Gihub release [v2.7.0](https://github.com/dfinity/evm-rpc-canister/releases/tag/evm_rpc-v2.7.0) for more details.

## Upgrade args

```
git fetch
git checkout 32c067d3b19ccc91e3abd991f9c6c2204466021a
didc encode -d candid/evm_rpc.did -t '(InstallArgs)' '(record {})' | xxd -r -p | sha256sum

## Wasm Verification

Verify that the hash of the gzipped WASM matches the proposed hash.

```
git fetch
git checkout 32c067d3b19ccc91e3abd991f9c6c2204466021a
"./scripts/docker-build"
sha256sum ./evm_rpc.wasm.gz
```
