What it is
What is crypto-to-fiat settlement (and stablecoin settlement)?
Stablecoin settlement is the process of discharging a payment obligation by converting an incoming crypto or stablecoin balance into fiat, or into a chosen stablecoin, on-chain. It reaches finality in seconds to minutes instead of the days a legacy bank transfer takes.
Settlement is not the same as acceptance. A crypto payment gateway takes the payment at checkout. Settlement converts and finalizes the funds you received, then pays them out in the currency you want. This page covers the settlement layer.
Boldrails settles as a licensed principal. We hold the funds, convert them, and pay you directly. We are not a card-network pilot and not a custody-infrastructure vendor.
Settle in fiat or crypto
Settle in fiat or crypto, remove volatility at settlement
Crypto prices move. Boldrails locks the exchange rate at the moment of settlement, so you know the exact amount you receive before the funds land. That single step removes the price risk of holding crypto between receiving a payment and settling it.
After the rate is locked, you choose how to settle. Take fiat to a bank account, or take stablecoin to a crypto wallet. You pick per corridor or per payout, and you can mix the two across your business.
We convert directly. We do not route you to a partner, a marketplace or an aggregator. One counterparty settles the funds, and one compliance relationship covers them.
| Settlement choice | What you receive | When | Volatility exposure |
|---|---|---|---|
| Settle to fiat | Local or major currency to a bank account | Instant or next business day, depending on the rail | Removed at rate lock |
| Settle to stablecoin | USDT or USDC to a crypto wallet | On-chain finality in minutes | Held in a fiat-pegged asset |
| Settle to crypto (BTC and others) | The asset you choose | On-chain finality in minutes | You hold the market position |
Speed and payouts
How fast is settlement, and how do payouts work?
Settlement speed depends on the leg. On-chain settlement in stablecoin reaches finality in minutes. A fiat bank settlement can be near-instant or next business day, depending on the local rail. Both beat legacy correspondent banking, which typically runs T+3 to T+5.
The payout leg works the same way. Settle out to many recipients in one batch with mass payouts, in fiat or stablecoin, through the payout API. This is the demand behind searches for crypto to bank: businesses want on-chain speed with money that lands in a normal bank account.
You can also hold and convert balances as working capital, which bridges into treasury use through our crypto OTC desk.
| Rail | Typical settlement speed |
|---|---|
| Legacy correspondent bank | T+3 to T+5 business days |
| Card processing | T+1 to T+5 business days |
| Fiat bank settlement (Boldrails) | Instant or next business day, by rail |
| Stablecoin settlement (Boldrails) | On-chain finality in minutes |
Legacy timing per the World Bank Remittance Prices Worldwide; "nearly instant" per McKinsey (2025).
Networks and stablecoins
Which settlement networks and stablecoins do we use?
Network choice drives both speed and cost, so we settle across several. TRON (TRC20) is a leading low-fee USDT rail, widely used in emerging-market corridors. Solana and Polygon are fast and cheap. Ethereum carries a higher network fee. USDC is the asset most used in regulated US and EU flows.
We settle the funding leg and the payout leg in fiat or stablecoin across these networks. We pick the network with you, based on your corridor and your cost target.
| Network | Typical use | Relative network fee | Common asset |
|---|---|---|---|
| TRON (TRC20) | Emerging-market USDT corridors | Low | USDT |
| Solana | Fast, low-cost settlement | Low | USDC, USDT |
| Polygon | Fast, low-cost settlement | Low | USDC, USDT |
| Ethereum | Regulated, high-value flows | Higher | USDC, USDT |
Pricing and API
Pricing, fees and the settlement API
We keep the fee structure clear. Crypto-to-fiat settlement has three parts: a settlement or processing fee, the blockchain network fee, and the FX or conversion spread applied when you settle to fiat.
Boldrails pricing is quote-based. Your rate depends on your vertical, your volume and your settlement currency, so we quote it directly rather than posting a headline number that would not fit your case. Request yours through Get started.
For context, legacy correspondent banking averages about 6% per the World Bank. Card processing runs roughly 2.5% to 3.5% and crypto settlement around 0.5% to 1%, per industry pricing.
| Fee component | What it covers |
|---|---|
| Settlement fee | Our conversion and settlement of the funds |
| Network fee | The blockchain cost, which varies by network |
| FX spread | The conversion margin on fiat settlement |
For developers
You settle through one API. We provide a stablecoin API, a crypto payout API and a settlement API, with webhooks for every state change. See the payout API and our payment gateway for the full integration reference.
Boldrails pricing is quote-based by vertical, volume and settlement currency. Market figures are context only: World Bank (legacy ~6%) and industry pricing (card ~2.5-3.5%, crypto ~0.5-1%).
Licensing and compliance
Is crypto-to-fiat settlement legal? Licensing and compliance
Crypto-to-fiat settlement is legal where the operator holds the market's crypto or VASP licence and runs anti-money-laundering checks. Rules differ by market, which is why the licence, not the technology, decides legality.
Boldrails holds the necessary licences required in the markets we serve, and we settle directly as principal, never via partners. We run KYB, KYC and sanctions screening on every merchant and every settlement. For the full picture, see licensing and compliance and how we work as a licensed principal provider.
| Market | Regulator or licence type | What it governs |
|---|---|---|
| European Union | MiCA CASP authorization | Crypto-asset services, including settlement |
| United States | GENIUS Act framework, FinCEN MSB, state money-transmitter licences | Payment stablecoin issuance and money transmission |
| United Kingdom | FCA registration under the money-laundering regulations | Crypto-asset AML supervision |
| Australia | AUSTRAC digital currency exchange registration | Digital currency exchange and settlement |
The regimes above are market context, not Boldrails self-claims.
Who it's for
Who it's for, high-risk and high-volume merchants
Boldrails is built for high-risk and high-volume merchants: forex and CFD firms, crypto businesses, e-commerce, and iGaming or betting operators where they are licensed. We accept the accounts most acquirers turn away, and we settle them.
Here is the wedge. Crypto-to-fiat settlement runs on the same rail as cards and the wider money stack and mobile money. One rail settles in fiat or crypto, with mass payouts in either. For large or recurring conversion, our crypto OTC and treasury desk handles the block volume, and our acceptance index shows the methods, currencies and settlement options we support.
