What Is StablR USD (USDR) and How Does It Work?
StablR USD (USDR) is a fiat-backed, MiCAR-compliant U.S. dollar
stablecoin issued by StablR to maintain a 1:1 peg with the U.S. dollar. As an
ERC-20 token on
Ethereum (and bridged to
Solana), every USDR is fully backed by U.S. dollar cash and cash-equivalents held in segregated, audited reserves, with daily Proof-of-Reserve attestations published on StablR’s website.
USDR leverages
smart-contract technology to enable seamless, low-cost transfers and programmable money on public blockchains. You can mint USDR by depositing USD via StablR’s dashboard or API (or purchase it on supported exchanges), and redeem it anytime 1:1 back into USD; on-chain transfers incur only standard network
gas fees, with no additional mint/burn charges from StablR.
When Was StablR USD Stablecoin Launched?
StablR Limited was established in December 2022 by CEO & Founder Gijs op de Weegh (formerly co-founder and COO of Payvision), alongside Corné van der Meijden (CROO), Julia Frendo (CFO), Robin Nijkamp (CTO) and Adam Csanyi (CCO). The parent company, Plutus B.V., was created in mid-2022 to handle StablR’s initial regulatory, legal and technical setup.

3. Late 2025: Enhanced governance modules—leveraging MiCA compliance, to introduce on-chain voting and reserve-management dashboards.
How Is USDR Fully Collateralized and Backed?
Every USDR token is backed 1:1 by U.S. dollar cash and cash-equivalents held in fully segregated accounts at top-tier financial institutions, ensuring that for every USDR in circulation there is an equal amount of fiat in reserve.
StablR publishes these reserve balances via daily
Proof-of-Reserve attestations, powered by
Chainlink’s decentralized
oracle network, and third-party
audits, so anyone can verify in near real-time that USDR’s on-chain supply never exceeds its off-chain collateral.
How do I Redeem (Sell) USDR Back Into Fiat USD?
To redeem USDR back into fiat USD via StablR, first log in to your StablR Account and ensure you’ve registered and verified a bank account (SEPA, SWIFT, T2 or BLINC) and whitelisted the
wallet holding your USDR. In the dashboard’s “Convert” or “Sell” section, select USDR, enter the amount you wish to redeem, choose your linked wallet and bank account, then confirm the transaction. StablR will automatically burn your on-chain USDR and, based on your banking partner’s cut-off times, initiate a USD payout to your bank, typically arriving within 1–3 business days.
If you hold USDR on BingX, you can also convert it to USD by going to your
Spot Wallet, selecting USDR, and choosing “Withdraw” or “Convert to Fiat.” Enter your bank details and the amount, confirm the order, and BingX will process the bank transfer under its standard fee and timing schedule (usually 1–3 business days).
What Are the Main Use Cases for USDR Stablecoin?
USDR is ideal for global payments, remittances,
DeFi collateral, FX hedging and any application requiring programmable, dollar-pegged value with near-zero transfer costs. You can also trade USDR on BingX’s Spot market by navigating to Spot Trading, filtering for “Stablecoins,” selecting the
USDR/USDT pair, and placing a
market or limit order as you would for other stablecoins.
Is StableR USD Stablecoin Audited, Transparent, and Safe to Use?
StablR USD (USDR) undergoes regular, independent third-party audits in accordance with the European Union’s Markets in Crypto-Assets (MiCA) regulatory framework. Auditors review and verify that all fiat reserves match the on-chain token supply, and StablR publishes these audit reports to its website, and to partners like Chainlink, for public scrutiny.
Beyond formal audits, StablR implements real-time transparency through Chainlink Proof-of-Reserve oracles. Every day, Chainlink fetches StablR’s off-chain reserve balances and posts them on-chain, so anyone can confirm that each USDR is backed 1:1 by segregated USD cash or cash-equivalents held at licensed banks. Combined with MiCA oversight and segregation of reserves, this infrastructure ensures USDR remains safe, fully collateralized, and auditable at any time.
Which Blockchains Support USDR Stablecoin?
USDR is issued as an ERC-20 token on Ethereum and can also be bridged to Solana as an SPL-USDR token, giving you access to both networks’ DeFi ecosystems.
What Are the Transaction Fees for USDR Transfers?
USDR transfers incur
only the underlying blockchain gas/network fees. StablR applies
no additional mint, burn, or transfer charges. On Ethereum (ERC-20), gas fees fluctuate with network congestion, typically ranging from
$0.50 to $7.00 per transaction (similar to
USDT transfers). On Solana, SPL-USDR transfers are even cheaper, often costing
less than $0.001 per transaction thanks to Solana’s high throughput and low-fee architecture.
Which Wallets Support USDR Stablecoin and How to Store It Securely?
You can securely hold USDR right in your BingX Spot Wallet. Just navigate to your Spot Wallet, select USDR, and choose “Deposit” to move tokens on-chain or “Withdraw” back to fiat when you’re ready; your funds remain protected by BingX’s enterprise-grade custody and optional withdrawal whitelisting.
For self-custody, USDR works with any Ethereum- or
Solana-compatible wallet. On Ethereum, you can use
MetaMask,
Ledger Nano, Trezor, or Zengo (USDR went live in Zengo on March 26, 2025). On Solana, you can store SPL-USDR with Phantom, Solflare, or Ledger. Always verify you’re using the official USDR contract address, enable
two-factor authentication where available, and consider a
hardware wallet for maximal security.
