Going on-chain: you pass identity checks, pay in by bank or card, and a provider issues or transfers stablecoin tokens to your wallet, typically backed by reserves the issuer holds. The tokens move on-chain between wallets with their own settlement finality. Coming back off-chain: an off-ramp provider takes your tokens, redeems them, and sends a normal bank payment to your account. A stablecoin balance is a claim against the issuer or provider, not a bank deposit.
The flow at a glance
Who’s involved
- User / business
- Party moving value between cash and stablecoins
- On-ramp provider
- Takes fiat in, runs KYC, and issues or delivers tokens
- Stablecoin issuer
- Mints and redeems the token and holds the backing reserves
- Blockchain network
- Records the on-chain token transfer between wallets
- Off-ramp provider
- Redeems tokens and pays out fiat to a bank account
- Bank
- Where the inbound funding and outbound payout actually settle
How it moves, step by step
- 1messageOn-ramp provider
The user completes identity verification (KYC) and links a bank account or card. This is onboarding messaging, not money movement.
- 2moneyBank
The user funds the on-ramp; bank-to-bank settlement moves the fiat to the provider's account. The cash is now real on the provider's side.
- 3moneyStablecoin issuer
Against that funding, stablecoin tokens arrive in the user's wallet, either freshly minted by the issuer or delivered by the provider from tokens it already holds. In a common model these tokens are backed by reserves the issuer holds.
- 4moneyBlockchain network
The user sends tokens on-chain to another wallet; the transfer settles on the network per its own finality rules, independent of any bank.
- 5messageOff-ramp provider
To cash out, the recipient instructs an off-ramp provider where to send fiat, after that provider's own identity checks.
- 6moneyOff-ramp provider
The recipient sends tokens to the off-ramp provider, who redeems them (the issuer burns them and releases backing reserves).
- 7moneyBank
The off-ramp provider initiates a bank payment; bank-to-bank settlement deposits fiat into the recipient's account. The funds are final once that settles.
- 8exceptionOff-ramp provider
If a payout fails compliance screening or a banking partner blocks it, the off-ramp can be delayed or rejected even though the on-chain transfer was already final.
When it’s final
On-chain token transfers often settle within seconds to minutes, but that finality is separate from bank finality. Funding an on-ramp and receiving an off-ramp payout still depend on bank rails, which can be near-instant or take several business days depending on the country and method.
Common misconceptions
Myth: A stablecoin balance is basically a dollar in a bank, just on the blockchain.
Reality: A stablecoin is a claim against the issuer, backed by reserves it holds, not a bank deposit in your name. Reserve composition, redemption rights, and any protections vary by issuer and are not the same as deposit insurance.
Myth: Once the tokens land on-chain, the whole payment is final and the cash side is done.
Reality: On-chain settlement is final for the token transfer only. Turning those tokens back into spendable bank money still requires an off-ramp and a separate bank settlement, which can be delayed or blocked.
