From any asset
to any bank in one API
Watch a wallet, move the funds, convert the asset, and land it in a bank account on the other side of the world — through a single integration.

Stop stitching together five integrations.
Use one.
Wallet monitoring, on-chain execution, asset conversion and global bank settlement — one platform, one API key, one interface across all four layers.
Verification handled
KYC and KYB come with the platform. Verify inline, or send your customer a link and we take it from there.
Screened before it moves
Every customer and counterparty is checked against global sanctions and watchlists before a payout leaves.
Local currency, local rails
Your customer is paid the way their bank expects it — their own currency, on the network their country actually uses.
One key, every layer
The same API key covers monitoring, transfers, conversion and payouts. Add a capability without adding an integration.
Four products. One platform.
Each layer works on its own or together — from spotting a deposit to settling funds in a bank account on the other side of the world.
Core
Monitoring & webhooks
Never miss a transaction. Add any wallet address and get notified the instant funds move. No polling, no missed deposits — real-time events, signed and delivered.
- HD wallet generation across EVM, Bitcoin, TRON, Solana
- Real-time deposit & withdrawal detection
- HMAC-signed webhooks with exponential retry
- 31+ chains: all major EVM networks, BTC, TRON, SOL
Pay
Transfers & paymaster
Send stablecoins across TRON and EVM networks without making your users manage gas. The paymaster sponsors the fee — your users just transact.
- USDT & USDC on TRC20, ERC20, BEP20, Polygon
- Gas sponsorship — no gas friction for your users
- Flat, predictable fee per transfer
- Multi-fallback RPC execution for reliability
Liquidity
Asset conversion
Accept any token, receive any other. Take a quote with a locked rate, send the funds, and FluxRail delivers the converted amount to your destination wallet.
- 300+ token pairs with live market pricing
- Locked-rate quotes — no slippage surprises
- Deliver converted funds to any wallet
- Track a swap through to settlement
Payouts
Global bank settlement
Pay a stablecoin balance out as local currency in a bank account. One call takes the amount and the destination currency, and FluxRail picks the rail.
- 75+ countries over ACH, RTP, SEPA, FPS, PIX, SWIFT and local rails
- Customer verification and sanctions screening included
- Crypto deposit wallets or fiat virtual accounts as the source
- Test mode is fully simulated — no money, same responses
Stablecoin to any bank, in three calls
No rail to choose, no correspondent to chase. Name the destination currency and FluxRail does the rest.
POST /api/v1/payouts/customers/
{"first_name":"Amara","last_name":"Eze","email":"amara@company.com","country":"US"}
# ← {"id": "cus_xxx", "kyc_status": "not_submitted" }
# 2. Fund them — a crypto deposit wallet (USDT/USDC) or a fiat virtual account
POST /api/v1/payouts/customers/cus_xxx/wallets/
{"token":"USDC","network":"ERC20"}
# ← {"address": "0x4f2a9c...", "source": "wallet" }
# 3. Send — just amount + destination; FluxRail debits the right balance
POST /api/v1/payouts/customers/cus_xxx/send/
{"amount":"250","dest_currency":"USD","method":"ach"}
# ← {"rail":"ach","status":"pending_approval" }
What teams build on FluxRail
From a solo developer to a fintech scale-up — one platform behind the whole money movement stack.
Freelancer & gig platforms
Pay contractors in their own currency, whatever your platform holds. Workers get a payout, not a crypto lesson.
Exchanges & trading apps
See deposits the moment they land on-chain, convert to what your system needs, and execute withdrawals — without running your own nodes or wallets.
Web3 games & consumer apps
Let players earn in-game and cash out to a bank account. No wallet to install, no chain to understand — they withdraw and money arrives.
Treasury & operations
Watch balances on every chain, convert at live rates, and settle to bank accounts across borders — all on a schedule instead of by hand.
Built for developers who ship fast
One API key unlocks all four layers. Every endpoint follows the same REST pattern, every webhook the same HMAC format. There is nothing new to learn as you add capability.
