Most fintech stablecoin stacks still split the world: a bank for dollars, an orchestrator for USDC or USDT, and a weekend wait when those two ledgers disagree.
The named object is Column N.A. native stablecoin rails: USDC and USDT built into Column's banking core so the stablecoin address and the bank account sit on the same ledger. Solana is the default network in Column's public API examples. Conversion to and from fiat runs 24/7 with no prefunding, and the same account can pair ACH, FedWire, RTP, FedNow, SWIFT, checks, and stablecoin-backed cards.
Facts below come from Column's Bank native stablecoins product page, the Sep 16, 2026 Stablecoins blog by Jeremy Batchelder, William Hockey's Completing the stack launch note, and secondary coverage from Solana Compass. Curl examples and object shapes are copied from Column's published docs. No invented fee tiers, asset totals, or undocumented endpoints.
Key Takeaways
- Column N.A. embeds USDC/USDT in its banking core; same ledger as the bank account.
- POST /transfers/crypto defaults to network=solana in Column's published examples.
- Same-ledger conversion is 24/7 with no prefunding float to manage.
- Stablecoins pair ACH, FedWire, RTP, FedNow, SWIFT, checks, and cards.
- Brex and Slash are named live builders; FDIC does not insure USDC or USDT.
Who this is for
Use this path if you are a fintech, treasury, or payments operator evaluating bank-native USDC/USDT rails, you already assume USDC, USDT, ACH, and Solana, and you want one core that can move dollars and stablecoins without a separate prefunded orchestrator wallet.
Skip it if you only need a Circle Mint third-party payout (see How to Send a Circle Stablecoin Payout), a Bridge virtual account onramp (see How to Open a Bridge Virtual Account for USDC), a non-Column card program (see How to Issue a BVNK USDC Card), or Circle CPN Managed Payments where Circle holds the assets (see How to Enable Circle CPN Managed Payments).
What Column N.A. stablecoin rails are
On September 16, 2026, Column published bank-native stablecoins: USDC and USDT interoperable with the U.S. dollar and Column's payment rails, "instant, 24/7, and built natively into Column," with "no middlemen."
Column's pitch is architectural. Other orchestrators wrap legacy cores, so "instant" still waits on wire windows and prefunded balances. At Column, the stablecoin address and bank account exist on the same ledger. Incoming stablecoins land as USD instantly; outgoing transfers debit the account and settle on chain.
Supported assets and networks per Column: USDC and USDT across Solana, Ethereum, and other major chains for on-ramps, wallets, off-ramps, pay-ins, and payouts. Key management, liquidity, and compliance stay behind Column's APIs. "You never touch a private key."
Secondary coverage (Solana Compass, Sep 16, 2026) notes Column N.A. as a federally chartered FDIC-member bank with about $1.77B in assets, and that Solana is the network value shown first in Column's developer examples. Treat the asset figure as reported coverage, not a Column product SLA.
Same-ledger model: why no prefunding
Here's the problem conventional stacks create. You prefund a crypto balance at an orchestrator, wait for a wire window to top up, then reconcile two systems when Saturday USDC arrives but Monday fiat is the only exit.
Column's same-ledger design removes that float layer for operators on its core. Product examples Column published:
- Receive USDC at 9 PM Saturday and pay it out over RTP the next second, instead of waiting for Monday's wire window.
- Debit an outside bank account over ACH and send USDC to a wallet with no prefunded stablecoin balance.
- Accept USDC (Column cites a Lagos treasury example) and forward dollars as a SWIFT wire so cash does not sit idle between rails.
Column states on the product page that "9:00 PM on a Saturday functions no different than 9:00 AM on a Tuesday." That is the operator claim to verify in sandbox before production cutover.
| Job | Legacy wrap pattern | Column same-ledger pattern |
|---|---|---|
| Weekend USDC inbound | Hold until wire window | Convert 24/7; payout RTP/FedNow next second |
| ACH debit → wallet USDC | Prefund orchestrator USDC | Debit ACH; send crypto; no separate float |
| Card spend vs stables | Issuer + processor + bank float | Authorize against live balance on Column |
Step 1: Confirm eligibility and bank account primitives
Column sells to technology companies building financial products, not as a retail consumer wallet. Before crypto transfers, you need the usual Column stack: entities with KYC/KYB evidence, bank accounts, and API keys. Reach out through Column's commercial path if stablecoins are not yet enabled on your platform.
Operator check: confirm you can already create ACH, book, wire, or realtime transfers on a funded bank_account_id. Stablecoins "plug into" those rails rather than replacing them. If basic banking APIs are not live, pause crypto enablement.
Step 2: Send USDC with POST /transfers/crypto (Solana default)
Column's product page documents the crypto transfer call with Solana as the example network. Use Column's documented amount units for USDC (the published example uses amount=250000 on a sample send).
Published example (API key and IDs are Column's documentation placeholders, not live secrets):
curl 'https://api.column.com/transfers/crypto' \
-u :<YOUR_API_KEY> \
-d bank_account_id=bacc_... \
-d amount=250000 \
-d currency_code=USDC \
-d network=solana \
-d destination_address="9xQeWvG8...VFin"
Required mental model from Column's object shape:
- currency_code: USDC or USDT
- network: solana in the default docs example; Ethereum and other major chains also supported
- destination_address: on-chain address on that network
- bank_account_id: the Column account that debits
Column shows a crypto_transfer object with status progressing submitted → completed on chain confirmation, plus webhooks at each step and a transaction_hash when submitted. Subscribe before you treat any payout as final.
{
"id": "crtr_...",
"object": "crypto_transfer",
"bank_account_id": "bacc_...",
"amount": 500000,
"currency_code": "USDC",
"network": "solana",
"destination_address": "9xQeWvG8...VFin",
"transaction_hash": "5UfDuX71...9rWq",
"status": "submitted"
}
Step 3: Pair fiat rails on the same account
That means… the value of Column's model is not the curl alone. It is that the same bank account can receive USDC and immediately fund a realtime USD payout.
Column publishes a FedNow example on the same operating account after a crypto receive:
curl 'https://api.column.com/transfers/realtime' \
-u :<YOUR_API_KEY> \
-d bank_account_id=bacc_... \
-d counterparty_id=cpty_... \
-d type=fednow \
-d amount=250000 \
-d currency_code=USD
Fiat rails Column lists alongside stablecoins: ACH, FedWire, RTP, FedNow, SWIFT, and checks. For classic cash-out patterns outside Column, see How to Off-Ramp USDC to ACH or Wire. For cart acceptance patterns, see How to Accept USDC Payments.
Step 4: Stablecoin-backed cards on the same core
Column argues most stablecoin-backed cards wrap separate orchestrators and issuers. With Column, orchestration, issuing, and processing sit behind one API set, so you can authorize card spend against stablecoins when they land (actual balance, not prefunded float), settle Visa and Mastercard in stablecoins 24/7, and run card programs without a dollar banking relationship in every country cardholders live.
Published card create example:
curl 'https://api.column.com/cards' \
-u :<YOUR_API_KEY> \
-d entity_id=enti_... \
-d bank_account_id=bacc_... \
-d type=VIRTUAL \
-d cardholder_name="Wei Lin Tan"
Full-stack card issuing launched the same day (Sep 16, 2026) with Column's own issuer processor for Mastercard and Visa across debit, credit, and stablecoin-backed cards, per William Hockey's launch post.
Who is already live
Column says the stablecoin product was built alongside large fintechs including Slash and Brex, and that stablecoins at Column are "already scaling quickly, with tens of billions in annualized volume." Column did not publish a precise dollar figure or measurement window in the blog post; treat that as a vendor claim to diligence.
Brex co-founder and co-CEO Henrique Dubugras, quoted on Column's launch materials: Column provides "the speed, flexible account model and API-first approach that no one else can." Hockey's full-stack note also names Ramp, Mercury, Bilt, Kapital, and others as clients across Column's broader suite, not all as stablecoin-specific proofs.
Who it is not for
On the flip side, skip Column native rails when:
- You need a consumer self-custody wallet UX rather than a bank API.
- Your compliance stack cannot complete Column KYC/KYB for the entities that will hold balances.
- You require Circle-held Managed Payments (CPN) instead of bank-core custody.
- You only need a one-off venue cash-out and will not integrate Column banking primitives.
- Your board expects FDIC insurance language on USDC/USDT itself. Dollar deposits at an FDIC bank are not the same as insured stablecoin balances.

FAQ
What are Column N.A. stablecoin rails?
Bank-native USDC and USDT built into Column's banking core so stablecoin addresses and bank accounts share one ledger, with 24/7 fiat conversion and no prefunding orchestrator float.
Does Column default crypto transfers to Solana?
Yes in Column's public product examples: network=solana appears on POST /transfers/crypto. Ethereum and other major chains are also supported.
Do I need to prefund USDC before sending?
Column's product claim is no separate prefunded stablecoin balance: debit the bank account and settle on chain. Confirm balances and holds in your sandbox before relying on that in production.
Which fiat rails work with Column stablecoins?
Column lists ACH, FedWire, RTP, FedNow, SWIFT, and checks, plus card networks for stablecoin-backed spend.
Are USDC and USDT on Column FDIC insured?
No. Column is an FDIC-member bank for eligible deposits, but USDC and USDT are not FDIC-insured deposits. Say that clearly in customer materials.
Who is already using Column stablecoin rails?
Column names Brex and Slash as builders on the stablecoin product and cites tens of billions in annualized volume without a precise disclosed figure.
How is this different from Circle Payouts or Bridge VAs?
Column is a bank core with crypto transfers on the same ledger as ACH/FedNow. Circle Stablecoin Payouts are third-party onchain sends from Mint. Bridge virtual accounts are fiat deposit instructions that convert into a crypto destination.
