MoneyGram launches USDC settlement using the Stellar blockchain

The partnership will enable MoneyGram customers to fund and withdraw from their accounts using the USDC stablecoin at physical branches.

Financial services company, MoneyGram International, has partnered with the Stellar Development Foundation to enable consumers to send money using Circle’s popular stablecoin, USD Coin (USDC) and convert directly to and from fiat.

Per a 6 Oct. announcement, MoneyGram has integrated support allowing crypto wallets connected to the Stellar Network to access its global retail platform. Working alongside Circle, MoneyGram will also enable “near-instant backend settlement”, account funding, and local fiat withdrawals using the USDC stable token.

United Texas Bank will act as the settlement bank to complete the process within the regulatory framework.

“As crypto and digital currencies rise in prominence, we’re especially optimistic about the potential of stablecoins as a method to streamline cross-border payments.” said Alex Holmes, MoneyGram Chairman and CEO.

The partnership is expected to launch at the end of 2021 in select jurisdictions, with an expanded international rollout planned in 2022. Denelle Dixon, CEO and executive director of the Stellar Development Foundation, stated:

“A new segment of cash users will be able to convert their cash into and out of USDC, giving them access to fast and affordable digital asset services that may have previously been out of reach.”

MoneyGram’s integration with Stellar comes just months after the firm moved to allow customers to withdraw crypto assets for cash via its point-of-sale outlets in the U.S. The service was rolled out in partnership with Bitcoin ATM and crypto exchange operator, Coinme Inc.

MoneyGram is no stranger to blockchain, having partnered with distributed ledger technology Ripple in June 2019 to collaborate on cross-border payments and foreign exchange settlements with digital assets.

However, the deal quickly went south, due to the uncertainty concerning U.S. Securities and Exchange Commission lawsuit targeting Ripple. MoneyGram suspended support for Ripple’s platform during the first quarter of 2021.

Stellar was launched by Ripple co-founder Jed McCaleb following his tumultuous departure from the project in 2014.

Circle published, on 4 Oct., filings revealing it is cooperating with a subpoena from the SEC that it received in July.

The technical benefits of EIP-1559

By Yuga Cohler

TLDR: EIP-1559 transactions have allowed Coinbase and Coinbase users to save ETH on gas prices without sacrificing confirmation times. Coinbase has also burned a lot of ETH, permanently reducing the supply of the second largest cryptocurrency by market capitalization.

On August 5, 2021, Ethereum’s “London” upgrade launched successfully on mainnet as the last hard fork before the transition to Proof-of-Stake / ETH 2.0. As one of the most anticipated upgrades, London included a significant change in Ethereum’s monetary policy and transaction fee structure — EIP-1559 — that has proven beneficial to both Coinbase and ETH holders at large.

In legacy transactions prior to London, senders would specify a single gas_price they were willing to pay for their transaction, and miners would select transactions based on a first-price auction. With London, the gas prices that senders pay are in part determined by a block-to-block base_fee_per_gas, which rises and falls with usage of the network.

EIP-1559 transactions allow senders to specify two values: max_fee_per_gas and max_priority_fee_per_gas. The former is an upper bound on the total gas price the sender is willing to pay, while the latter is an upper bound on the gas price the sender is willing to pay to the miner of the transaction. The effective_gas_price, i.e. the amount that the sender actually pays, is then computed as:

priority_fee_per_gas = min(
transaction.max_fee_per_gas — block.base_fee_per_gas
effective_gas_price = priority_fee_per_gas + block.base_fee_per_gas

The block’s base_fee_per_gas is burned, thereby making the native currency more deflationary and returning value to ETH holders.

While there was significant uncertainty surrounding the market effects of EIP-1559, we at Coinbase took a proactive approach to ensure that our infrastructure was prepared to send EIP-1559 transactions on day one of the fork. Based on the work of people such as Zsolt Felföldi and Frederik Bolding, we developed a novel gas pricing algorithm for these transactions. Crucially, it leverages the new eth_feeHistory JSON RPC API that allows us to dynamically compute an appropriate max_priority_fee_per_gas based on market conditions.

We rolled out this change gradually so that we could compare the metrics of legacy and EIP-1559 transactions. Our findings were surprising:

  • On average, we saved about 9% on effective gas prices (this was computed as the difference in confirmed gas price between legacy transactions and EIP-1559 transactions).
  • At the same time, we improved our broadcast-to-confirmation time by 11 seconds, or 0.7 blocks (this was computed as the difference in broadcast-to-confirmation time between legacy transactions and EIP-1559 transactions).

As Taylor Monahan posits, we suspect that we are able to simultaneously save on gas price and improve confirmation time because we specify a max_fee_per_gas that is significantly larger than the current base_fee_per_gas. This makes the effective priority_fee_per_gas larger than the equivalent legacy transaction, incentivizing miners to include our EIP-1559 transaction in the next block.

Coinbase executes a large number of transactions on Ethereum to source liquidity and provide withdrawals for our customers, so these savings add up. As of September 27, 2021, Coinbase has burned 13,800 ETH, for an average of about 254 ETH per day. This means we save about 27 ETH per day on gas prices from EIP-1559 transactions. Seeing this data, we have rolled out EIP-1559 to 95% of transactions, preserving a small holdback for data collection purposes. We intend on eventually rolling it out to 100%.

The London upgrade was a remarkable achievement not just for Ethereum, but for decentralized financial networks as a whole. A diverse group of participants across the world came together to implement a complex shift in one of the core mechanisms that dictates market prices. We’re looking forward to continuing to work with the Ethereum community to push forward the cutting edge of DApps & DeFi, and usher in the new era of ETH 2.0.
