Column integrates USDC and USDT into core banking infrastructure for fintechs

Column, the bank-as-infrastructure provider co-founded by Plaid co-founder William Hockey, has wired stablecoin payments directly into its core banking ledger. The integration supports both USDC and USDT across multiple blockchain networks, letting fintech clients move between crypto and traditional payment rails without ever leaving Column’s system.

What Column actually built

The integration allows Column’s fintech clients to send, receive, and convert USDC and USDT with immediate fiat conversion and settlement. That settlement runs 24/7/365 on Column’s own ledger. Solana serves as the default blockchain network, with Ethereum and other chains also supported.

Column says the system requires no prefunding, no third-party intermediaries, and no separate liquidity management. The stablecoin infrastructure is already live and processing transactions for a roster of well-known fintech clients including Brex, Ramp, Mercury, Bilt, Slash, and Kapital. According to Column, stablecoin transactions flowing through its system already reach tens of billions of dollars annually.

The broader product suite

Column didn’t stop at stablecoins. Alongside the crypto integration, the company announced three additional products: full-stack card issuing, global banking accounts, and multicurrency accounts.

The card issuing product lets fintechs launch branded debit and credit card programs without needing a separate card processor. Global banking accounts extend Column’s reach beyond US borders, while multicurrency accounts allow clients to hold and transact in multiple currencies from a single integration point.

Hockey described the stablecoin integration as the culmination of a multi-year initiative aimed at letting fintechs innovate through a unified bank integration.

Why this matters for stablecoin adoption

Column’s approach collapses the fragmented stablecoin-to-fiat stack into a single integration. For a fintech building on Column’s infrastructure, accepting a USDC payment becomes functionally identical to processing an ACH transfer.

The client list reinforces this point. Brex, Ramp, and Mercury are corporate spend management and banking platforms serving tens of thousands of businesses. When these platforms gain native stablecoin capabilities, the downstream effect is that their business customers gain those capabilities too.

Column’s competitive positioning is worth noting. Column holds its own California bank charter rather than relying on partner banks, giving it more direct control over compliance and operations.
