### Funded Goal: 24,000 USD

The MAGIC Monero Fund raised funds for noot to continue development on ETH-XMR atomic swaps. View [the campaign here](https://www.gofundme.com/f/noot-ethxmr-atomic-swap-development-4-months).

This proposal covers 4 months of work focused on the following:

### Relayer support

The current implementation of the protocol requires the ETH-recipient to have some ETH in their claiming account to pay for the transaction fees to claim the swap ETH. However, this is bad for UX and privacy, as users cannot withdraw to fresh ETH accounts.

To allow for users to claim ETH into a fresh account, integration with a relayer service can be implemented. This will allow users to withdraw to a fresh account by paying a small fee to a relayer to submit the transaction on their behalf.

### Ethereum privacy improvements

On the ETH side of the swap, there is no privacy, and which accounts and amounts participating in the swap are visible.

### ERC20 support

To support swaps for ERC20s without hurting liquidity, the swap contract can be integrated with a DEX such as Uniswap to automat-ically swap received ETH for the desired ERC20 token.

### Disk permanence

The current implementation of the swap does not store anything to disk apart from information needed for recovery of swap funds in case of failure. However, there are other components that should be stored to disk and restored upon reload, such as current swap of-fers made, historic swap information, and peer information. This will require a simple key-value database implementation.

### General maintenance and bugfixes

See https://github.com/noot/atomic-swap/issues for open issues on the repo. Issues not covered by the above work are part of this sec-tion. This includes RPC calls and documentation, codebase maintenance, testing, and fixes of any bugs found during testing.

ETH<>XMR Atomic Swap Continued Development

### Funded Goal: 12,000 USD

ACK-J created a series of Monero transactions using different spend patterns and applied artificial intelligence models to determine the resiliency of ring signatures against these models, absent external information. The MAGIC Monero Fund approved the research grant from its general fund.

The full paper "Lord of the Rings: An Empirical Analysis of Monero's Ring Signature Resilience to Artifically Intelligent Attacks" is available [on the author's GitHub](https://raw.githubusercontent.com/ACK-J/Monero-Dataset-Pipeline/main/Lord_of_the_Rings__An_Empirical_Analysis_of_Monero_s_Ring_Signature_Resilience_to_Artificially_Intelligent_Attacks.pdf), along with [the accompanying dataset pipeline](https://github.com/ACK-J/Monero-Dataset-Pipeline).

The transcript of a short inverview with ACK-J discussing the results is [here](https://magicgrants.org/Monero-Tracing-Research/).

## Main results

With 11 ring members, public information on the Monero blockchain could aid an attacker in predicting the true spend of a transaction greater than the random guessing probability of 9% (1/11). With this model, the likelihood of a correct guess grew to 13.3%, a modest increase. Since the data was collected, Monero increased its ring size to 16; thus, the accuracy should now be lower, but we do not have numbers for this.
