SoFiUSD's Monad expansion is backed by BitGo infrastructure

According to SoFi, SoFiUSD launched on Ethereum on December 18, 2025, becoming the first stablecoin issued on a public blockchain by a U.S. nationally chartered, FDIC-insured depository institution.

How is SoFiUSD backed and redeemed?

The token is redeemable 1:1 for US dollars. Its cash reserves sit primarily in SoFi Bank's Federal Reserve account, while regular third-party attestations confirm the backing.

The disclosed structure combines a banking reserve account with recurring third-party verification and public-chain distribution. It gives SoFiUSD a direct dollar redemption route through the bank while leaving the token available across multiple networks.

No attestor name, reserve balance or redemption volume appears in the disclosed details, so the information establishes the backing framework without quantifying usage or reserves at a point in time.

How did SoFiUSD expand beyond Ethereum?

On March 5, 2026, SoFi announced a partnership with BitGo covering infrastructure and distribution. BitGo's Stablecoin-as-a-Service platform became the engine for placing SoFiUSD on additional chains.

The rollout came in stages. SoFiUSD reached Solana by April 2026. SoFi announced the Monad integration around Aug. 25-26, 2026. That leaves SoFiUSD with an announced presence on three public networks: Ethereum, Solana and Monad.

The deployment announcements do not disclose chain-specific balances, active addresses or transaction counts. Their immediate significance is operational: SoFi has used one token across several networks, with BitGo responsible for the infrastructure and distribution work supporting the expansion.

The sequence matters because BitGo's mandate covers both infrastructure and distribution, not a single chain. SoFi announced the agreement before the Solana and Monad milestones, making the later deployments part of a coordinated multichain rollout rather than isolated listings.

That structure keeps three functions distinct: SoFi Bank holds the cited reserves, BitGo supports chain deployment, and SoFi controls the member-app access through which users can buy, sell, hold and convert SoFiUSD.

Why did SoFi select Monad?

Monad is a Layer 1 blockchain built for speed. SoFi's launch details say it can process over 10,000 transactions per second using parallel execution.

The capacity figure describes Monad's potential throughput, not SoFiUSD transaction volume. SoFi has outlined 24/7 settlement, business-to-business payments and remittances as uses for the token. Those applications make continuous availability and processing capacity central to the chain-selection rationale, while the announcement leaves actual SoFiUSD demand unquantified.

Keone, whose background is in high-frequency trading, adds a trading-market perspective to the discussion of execution speed and settlement.

What has the wider rollout delivered?

• May 2026: SoFi opened SoFiUSD access in its member app. Nearly 15 million SoFi members can use it to buy, sell, hold and convert the stablecoin. The membership figure measures the reach of the access channel, not disclosed active users.
• By September 2026: Card settlement went live. Through a partnership with Mastercard, SoFi aims to channel over $25 billion in annualized card volume into the SoFiUSD ecosystem. The figure is a corporate target, not a reported settlement total.
• October 2026: SoFi added a tokenized deposit product. That gives SoFi Bank another blockchain-based offering alongside SoFiUSD, extending SoFi's product set beyond the stablecoin itself.

Together, the announcements describe a multichain distribution structure built around SoFi's reserve-backed token, BitGo's infrastructure, the member app and Mastercard's card channel. The tokenized deposit adds another blockchain-based banking product rather than replacing the stablecoin.

The business test is whether that distribution produces sustained payments and remittances at commercial scale. The next market-structure checkpoint is disclosed payment activity across Ethereum, Solana, Monad and the Mastercard channel; SoFi has announced no deadline for reporting that conversion.
