2.6 Fiat Onramp & Offramp
The transition between traditional fiat currencies and digital assets is a seamless process within the WeFi ecosystem. While the Onchain Banking Account unifies fiat and crypto into a single balance, the onramp and offramp processes are the mechanisms that synchronize these two currency systems.
Deobanks serve as the primary providers of these services, leveraging their regulatory licenses and banking partnerships to facilitate the minting and burning of stablecoins in direct response to fiat movements.
The Fiat Synchronization Architecture
Onramping and offramping are not standalone products but integrated services within the broader Deobank offering. These processes connect traditional payment rails with WeFi's onchain infrastructure via direct access to minting/burning mechanisms.
From the user's perspective, they simply top up their Onchain Bank Account with fiat (USD, EUR, etc.) and see their balance in familiar currency terms. Behind the scenes, this fiat is backed 1:1 by stablecoin reserves (USDC, EURC), but users never interact with the technical conversion mechanics.
User Experience: A user deposits $100 and sees $100 in their account. They can spend it as USD via card, transfer it as USDC to a crypto wallet, or send it as a bank transfer—all from the same unified balance without any "exchange" step.
While users experience seamless account top-ups, the underlying infrastructure performs fiat synchronization through regulated liquidity providers. These backend processes ensure every fiat deposit is backed by onchain assets and every withdrawal is properly settled.
Onramp
Fiat → Crypto
Backend minting and crediting of synthetic fiat backed by stablecoin reserves when users deposit traditional currency.
Offramp
Crypto → Fiat
Backend burning of stablecoins and settlement of fiat when users withdraw to external accounts.
How Onramping Works
When a participant deposits fiat currency into the ecosystem, Deobanks facilitate the conversion through regulated liquidity providers.
1
Deposit Initiated
Participant initiates a fiat transfer via traditional banking rails (wire transfer, SEPA, local payment networks).
2
Custody & Verification
Deobank receives fiat through regulated custody infrastructure. Identity verification occurs per regulatory requirements.
3
Stablecoin Minting
Licensed liquidity providers mint equivalent stablecoins (USDC, EURC) 1:1 to the fiat received.
4
Synthetic Settlement
Stablecoins are deposited directly into the participant's Distributed Custody Wallet, recorded on the Onchain Accounting Book.
5
Unified Balance
The Onchain Banking Account reflects the new balance, instantly available for spending, trading, or mining.

How Offramping Works
1
Offramp Request
Participant initiates an offramp request from the Onchain Banking Account, specifying amount and the Fiat asset destination.
2
Smart Contract Execution
The system debits the participant's stablecoin balance and burns the equivalent amount through licensed liquidity providers.
3
Fiat Settlement
Liquidity providers release equivalent fiat to the Deobank's settlement account.
4
Bank Transfer Execution
Deobank executes a bank transfer to the participant's designated external account via traditional rails.
5
Confirmation
The transaction is recorded on the Onchain Accounting Book, providing blockchain-recorded proof of the offramp.
