Review Tornado Cash Proposal 66

Review Tornado Cash Proposal 66

Proposal #66: Update the ETH RPC List and ENS - 50 TORN

Expenditure: 50 TORN

Reason: The current default Blockscout RPC is unusable because it enforces a strict JSON-RPC mode.

The feeOracleV4 and feeOracleV5 calls in tornado-oracles do not include the latest block parameters, causing compatibility issues with strictly compatible RPC endpoints.

A Verification Guide for CoW TWAPs.

Verify CoW TWAPs

The target contract is ComposableCoW: 0xfdaFc9d1902f4e0b84f65F49f244b32b31013b74.

To invoke a CoW TWAP, we call the function createWithContext:

A step-by-step guide to deploy a 1-out-of-1 Safe `1.4.1` contract via `CreateX`.

Safe 1.4.1 Deployment via CreateX

Special thanks go to Richard Meissner for feedback and review.

Important

This approach requires a deep understanding of how the Safe contracts and CreateX mechanisms work. The recommended way to deploy a Safe contract remains through the SafeProxyFactory contract.

We will deploy a 1-out-of-1 1.4.1 Safe contract via CreateX.
