Transform Idle XRP Into Active Assets.

Doppler Finance is the leading XRPfi yield infrastructure protocol natively built on the XRP Ledger. Its mission is to "Transform Idle XRP into Active Assets" — providing institutional-grade, custody-secured yield to XRP and RLUSD holders. Users deposit XRP into the XRP Vault (~3.2% APR) or RLUSD into the RLUSD Vault (~8% APR). Doppler is backed by DCG, Hashkey Capital, GSR, Maven 11, Keyrock, the Ripple Eco Fund, and Futureverse, and raised a $3M seed round in August 2025 led by Reforge.

XRPfi is a term coined by Doppler Finance to describe a new DeFi paradigm built specifically for XRP and the XRP Ledger ecosystem. Just as "DeFi" broadly refers to decentralized finance on Ethereum, XRPfi refers to the emerging ecosystem of decentralized financial products — yield, lending, staking, RWA tokenization — built natively on XRPL. Doppler Finance is pioneering XRPfi by creating the foundational yield infrastructure layer that other XRPL protocols, wallets, and institutions can build upon. Less than 0.1% of XRP's ~$200B market cap currently generates on-chain yield — XRPfi aims to change that.

Doppler Finance currently offers two yield vaults: the XRP Vault, where users deposit XRP and earn XRP-denominated yield at approximately 3.2% APR (weekly variable rate), and the RLUSD Vault, where users deposit Ripple's RLUSD stablecoin and earn USD-denominated yield at approximately 8% APR. The RLUSD Vault is supported on both XRP Ledger and Ethereum. Additional vaults and yield strategies are under active development and will be rolled out in future updates.

RLUSD is Ripple's native USD-pegged stablecoin issued on both the XRP Ledger and Ethereum. It maintains a 1:1 peg with the US dollar and is backed by US dollar deposits, short-term US government treasuries, and money market funds in regulated accounts. Doppler uses RLUSD as a core yield-bearing asset because it is the primary liquidity engine of the XRPfi ecosystem — combining the stability of a dollar peg with deep XRPL liquidity. Depositing RLUSD into Doppler's vault earns approximately 8% APR with zero crypto price exposure.

Doppler generates yield through a diversified mix of CeDeFi strategies (centralized finance execution with on-chain transparency), DeFi protocols on XRPL, and real-world asset (RWA) strategies including tokenized US Treasury bills and other yield-bearing instruments. All strategies are executed off-exchange through regulated custody providers (Fireblocks, BitGo, Copper, Ceffu) — user assets never touch a centralized exchange's hot wallet. Each strategy is independently audited before deployment and yield rates are published weekly.

Doppler Finance uses the same custody infrastructure trusted by global financial institutions: Fireblocks (the largest institutional crypto custody platform, securing $4T+ in assets), BitGo (regulated qualified custodian, pioneer of multi-sig custody), Copper (institutional custodian and DeFi prime broker), and Ceffu (Binance's regulated institutional custody arm). All custody arrangements are subject to regulatory compliance, segregated asset management, and real-time Proof of Reserves — full on-chain solvency tracking is available at all times, not just periodically.

Proof of Reserves (PoR) is a cryptographic verification method that proves a protocol actually holds the assets it claims to hold. Doppler implements real-time solvency tracking — not periodic snapshots like many exchanges — meaning anyone can verify at any moment that depositor assets are fully backed. This is implemented through the on-chain verification capabilities of Doppler's custody providers. PoR was a critical design requirement from day one, directly in response to the failures of centralized platforms like FTX and Celsius that lacked verifiable reserves.

Yes. The RLUSD Vault smart contracts have been fully audited by Zenith — a respected blockchain security team with a track record including audits for 1inch, Succinct, Berachain, and over 50 top DeFi protocols. Zero critical vulnerabilities were found. Doppler has also undergone independent legal audits to ensure regulatory compliance across all jurisdictions of operation. Full audit reports are available in Doppler's documentation. All smart contracts are open-source and verifiable on XRPL Explorer and Etherscan.

Depositing is straightforward: connect your XRPL wallet (XUMM/Xaman, Ledger, Crossmark, GemWallet, D'CENT) or Ethereum wallet (MetaMask, WalletConnect) for the RLUSD Vault. Visit app.doppler.finance, select either the XRP Vault or RLUSD Vault under the "Vaults" tab, enter the amount you want to deposit, and sign the transaction. The process takes under 30 seconds. Zero deposit fees are charged — only standard XRPL network fees (~$0.0004) or Ethereum gas apply.

When you are ready to withdraw, submit a withdrawal request through the Doppler app. There is a 7-day withdrawal window during which funds are batched for processing. For XRPL users, withdrawn RLUSD is sent directly back to your XRPL wallet after the batch processes. For Ethereum users, you claim your withdrawn RLUSD once the batch is processed (approximately 01:00 UTC daily). Zero withdrawal fees are charged by Doppler — only applicable network gas fees apply.

Doppler Points (DP) are reward units earned by early depositors of the Doppler Finance protocol. Your vault balance accrues DP continuously based on the amount deposited and the duration of your deposit. The RLUSD Vault launched with an Early-Depositor DP Boost — multiplied point accrual for the first wave of depositors. DP rewards are expected to be convertible to protocol benefits, governance rights, or other incentives as the Doppler ecosystem matures. Full DP reward multipliers and timelines are available in the Doppler documentation.

Doppler Finance's vault yields are variable rates — they fluctuate based on market conditions, strategy performance, and protocol utilization. Current indicative rates are approximately 3.2% APR for the XRP Vault and 8% APR for the RLUSD Vault. Rates are published weekly on the Doppler app and blog. Unlike protocols that advertise fixed high APYs subsidized by token emissions, Doppler's yields come entirely from real strategy revenue — making them sustainable but variable rather than artificially inflated.

Auto-compounding means your earned yield is automatically reinvested into your position the moment it arrives — so both principal and earned interest compound together continuously. This is enabled by default on both Doppler Vaults. For the RLUSD Vault, "the moment your RLUSD lands, yield is reinvested automatically — so both principal and interest grow together, always denominated in RLUSD." At 8% APR with continuous compounding, the effective annual yield is approximately 8.33% EAPR.

Doppler Finance supports the following wallets: For XRP Ledger: XUMM (Xaman) — the recommended official XRPL wallet; Ledger hardware wallet via XRP app; Crossmark browser extension; GemWallet; and D'CENT hardware wallet (official Doppler partnership). For Ethereum (RLUSD Vault): MetaMask, WalletConnect, and any ERC-20 compatible wallet. Additional wallet integrations are being added continuously — check app.doppler.finance for the latest supported wallets.

Doppler Finance closed a $3M oversubscribed seed round in August 2025, led by Reforge with participation from: DCG (Digital Currency Group), Hashkey Capital, GSR, Maven 11, CMCC Global's Titan Fund, Keyrock, Tenity, CRIT USA, Cluster Capital, Flowdesk, Auros, and G20. The Ripple Eco Fund and Futureverse also back Doppler. The oversubscribed round signals strong institutional conviction in XRPfi as an emerging sector.

Off-exchange execution means Doppler's yield strategies are conducted outside of centralized exchange order books — user assets are never deposited into an exchange's pooled hot wallet where they could be commingled, misused, or lost in an exchange failure. Custody providers (Fireblocks, BitGo, Copper) facilitate off-exchange settlement, ensuring assets remain in segregated custodial accounts at all times. This directly addresses the counterparty risk that caused catastrophic losses for users of Celsius, FTX, BlockFi, and similar platforms.

In September 2025, VivoPower International — a NASDAQ-listed sustainable energy company — committed $30M to Doppler Finance as the first deployment in a planned $200M XRP Treasury yield program. A Steering Committee composed of both parties oversees phased tranche deployments, risk management, and performance reporting over a 24-month partnership term. This represented one of the largest single institutional capital commitments to an XRPL-native DeFi protocol, demonstrating that Doppler's infrastructure meets institutional treasury management standards.

Yes — Doppler Finance was engineered for institutional adoption from day one. The platform supports API and SDK integrations, allowing custodians, wallets, exchanges, and financial platforms to plug into Doppler's yield infrastructure and unlock XRP and RLUSD yield for their users. For direct institutional onboarding (funds, wealth managers, fintech platforms, corporate treasuries), Doppler offers a dedicated institutional access pathway with white-glove support, custom reporting, regulatory documentation, and direct integration with Fireblocks, BitGo, and Copper institutional APIs.

CeDeFi (Centralized-DeFi) is a hybrid model that combines on-chain transparency and non-custodial ownership with the capital efficiency and regulatory compliance of traditional finance. In pure DeFi, all yield strategies execute on-chain — which is transparent but sometimes capital-inefficient. In CeDeFi, yield strategies execute through regulated off-chain institutions (exchanges, market makers, lending desks) while smart contracts ensure on-chain verifiability of balances and reserves. Doppler uses CeDeFi to access yield opportunities — like prime brokerage and institutional lending — that pure on-chain DeFi cannot reach, while maintaining full custody and transparency standards.

Doppler Finance carries several risk categories users should understand: XRP price risk — the XRP Vault earns XRP yield, so USD value may decrease if XRP price falls (though XRP balance grows); Smart contract risk — despite audits, all smart contracts carry residual technical risk; Counterparty risk — Doppler relies on institutional custodians (Fireblocks, BitGo, Copper) whose own failure would be a systemic event; Strategy risk — CeDeFi and RWA strategies may generate lower yields than projected in adverse market conditions; and Withdrawal liquidity risk — the 7-day withdrawal window means assets cannot be retrieved instantly. Doppler mitigates all risks through diversification, audits, Proof of Reserves, and institutional custody partnerships.

Doppler Finance differentiates itself in three fundamental ways: Institutional-grade custody — unlike most DeFi protocols that rely solely on smart contracts, Doppler integrates Fireblocks, BitGo, and Copper for segregated, regulated custody; Real, sustainable yield — rather than offering speculative 20%+ APY subsidized by token emissions, Doppler offers conservative but real yields (~3.2% XRP, ~8% RLUSD) sourced entirely from legitimate financial strategies; and Regulatory compliance — Doppler is designed to meet institutional regulatory requirements from day one, with legal audits, KYC/AML compatibility, and documented risk controls — making it viable for regulated funds, wealth managers, and corporations.

Doppler Finance is an independent protocol built on the XRP Ledger — it is not owned or operated by Ripple Labs. However, Doppler has significant Ripple ecosystem connections: the Ripple Eco Fund is a backer of Doppler Finance, signaling Ripple's institutional support; Doppler's RLUSD Vault is built around Ripple's own stablecoin; and Doppler has partnered with SBI Ripple Asia and Evernorth (supported by Ripple and SBI Holdings). Ripple Labs' recognition of Doppler as a core piece of the XRPL ecosystem underscores Doppler's strategic alignment with the broader Ripple/XRPL mission of institutional blockchain adoption.
