Solana Foundation Report: Stablecoins Cut Remittance Fees and Reach 1.3B Unbanked

The Solana Foundation published a report titled "An Evolution of Money Movement: How Stablecoins on Solana Are Reshaping Remittances", documenting the structural cost of the $905 billion annual global remittance market and the case that stablecoin infrastructure on Solana is already addressing it.

The central finding: a $200 wire on traditional rails carries an average fee of 6.49% and clears in three to five business days. A stablecoin transfer on Solana settles near-instantly for a fraction of a cent per transaction. The report positions this gap as a present-tense condition, citing Western Union, Zepz, and Tala as operators who have already deployed production systems on the network.

Why Traditional Fees Stay High: Nostro Accounts and Frozen Capital

The fee problem in remittances is structural. Money transfer operators must maintain pre-funded balances (known as "nostro" accounts) in destination currencies before any transfer is processed. This locks up hundreds of billions of dollars in idle capital across the correspondent banking network. That capital has a cost, which flows through to the fees a sender pays.

The corridors with the fewest correspondent banking relationships have the highest fees, because operators must pre-fund deeper or route through more intermediaries. As the Foundation's report states, "Remittance rails have scarcely changed in fifty years." The infrastructure was designed in the mid-20th century and has been digitized at the edges without any change to the settlement layer underneath.

Stablecoin Settlement on Solana: The Capital Efficiency Case

A USDC (USDC) or similar stablecoin transfer does not require pre-funded accounts in the destination currency. Capital moves when the sender initiates the transaction. There is no float sitting in a correspondent account waiting to be matched. The marginal cost of a transfer approaches the transaction fee itself, which on Solana is a fraction of a cent.

The report documents four distinct implementation paths for money transfer operators, covering different combinations of custody model, conversion infrastructure, and user-facing interface. It frames the Solana layer as "high-speed rails and plug-and-play composable infrastructure," letting operators select settlement, conversion, and wallet components independently.

Western Union, Zepz, and Tala: Three Production Implementations

Western Union launched USDPT, a USD-backed stablecoin issued via Anchorage Digital Bank, alongside a Stablecard product built with Rain. The product gives customers a way to hold dollars at the receiving end without routing funds back through the US banking system. Western Union's move into stablecoin infrastructure is documented in a Breakpoint 25 fireside with Anchorage Digital's Sergio Mello.

Zepz, which operates WorldRemit and Sendwave, launched Sendwave Wallet to give recipients in more than 100 countries access to stablecoin-denominated balances without requiring an existing bank account, per the Foundation's report. The deployment rationale is covered in a Breakpoint 25 talk by Zepz, where the team outlined how inflation and currency volatility in emerging markets make dollar-denominated wallets more useful than local-currency accounts for many recipients.

Tala, a fintech serving 13 million customers in emerging markets, deployed a $50 million tokenized lending facility via Huma Finance HUMA$0.023-2.4% on Solana, per the Foundation's report. The facility gives borrowers access to stablecoin-denominated credit without a traditional bank account as a prerequisite, meaningful in markets where formal credit histories are rare.

Infrastructure Layer: Yellow Card, Bitso, and Local Currency Conversion

Converting stablecoins to local currency at the receiving end remains the friction point for mass adoption, and the report addresses it through a named infrastructure stack. Yellow Card handles local currency conversion across African markets, operating in corridors where correspondent banking access is limited and traditional off-ramp fees are highest.

Flutterwave, Bitso (covering the US-Mexico corridor), Trace Finance, and Sphere Pay are listed as additional conversion infrastructure, each handling specific corridors or currency types. The report frames these providers as interchangeable modules: a money transfer operator deploying on Solana selects the settlement layer, the conversion layer, and the wallet interface independently, with no lock-in between them.

The 1.3B Unbanked and the Smartphone Distribution Channel

Of the 1.3 billion adults the report estimates lack a formal bank account, nearly half already carry a smartphone. The report identifies that device as the primary distribution channel for stablecoin wallets, arguing that the barrier to adoption for unbanked recipients is institutional rather than technological: existing fintech products have generally required a bank account to onboard.

The corridors where the unbanked population is largest overlap with the corridors where traditional remittance fees are highest: US-Mexico, US-Brazil, US-Nigeria, US-Philippines, and US-India are all analyzed in the report with corridor-specific fee and infrastructure data.

The Solana Foundation signed a stablecoin remittance MOU with Toss Bank in June 2026, covering cross-border pilots with South Korea's third-largest internet bank and its 15 million customers. The Foundation's report documents that the consumer-facing layer above that infrastructure is already in production, with several of the named operators live on mainnet.
