Getting to know Strobe: A preview of mainnet launch

As we approach the mainnet launch of Strobe Finance, it’s time to get familiar with what’s coming on day one. While protocol development is an ongoing journey, and Strobe will continue to evolve with new features over time, we’ve now finalized and fully tested the launch Beta version. That means it’s time to hand things over to the community and open the doors.

Launch Assets

Strobe is launching with four assets, remember that all of the assets are on XRP Ledger Mainnet, that’s the chain you’ll need to deposit from into Strobe. The launch assets are:

• Native XRP
  Front and center, XRP is the main player both on Strobe and across the XRPL ecosystem. It is one of the most widely adopted digital assets, with deep liquidity, global exchange coverage, and a strong track record of both security and real-world utility. XRP is also the gas token for both XRPL and the XRPL EVM Sidechain, so make sure to keep a little in your wallet at all times.
• Axelar USDC (USDC.axl)
  Axelar’s USDC.axl is a bridged version of USDC, brought to XRPL via the Axelar Network. It’s backed one to one with native USDC and works just like the original. A stablecoin asset is essential for strategies like leverage and short-selling.
• Axelar Wrapped WBTC (WBTC) and Axelar Wrapped WETH (WETH)
  These are Axelar’s bridged versions of Bitcoin and Ethereum, also brought to XRPL via the Axelar Network. Again, each is backed one to one by the original asset and retains the same functionality, allowing users to supply, borrow, and collateralize across the Strobe protocol. We recognise the importance of these assets in the wider crypto ecosystem, so we’re catering to users who want to maintain diversity in their portfolios.

Note: Users should be aware tthat here may not be native liquidity for these assets on XRPL at launch. If you want to deposit into Strobe with them, you’ll likely need to bring that liquidity across from other EVM networks. To support this, Strobe has a built-in “Swap” function, and detailed user guides are available in both text and video format.

Supply and Borrow Caps

Everything we do at Strobe revolves around a security-first approach. We recently published a two-part series on protocol security, and we encourage you to give it a quick recap:

• Security First — Part One of Two: Code and Contracts
• Security First — Part Two of Two: Secure by Design

Supply and borrow caps at launch are a core part of that security architecture. They help build confidence and trust in a controlled way, which is essential for the long-term success of the protocol. The aggregated cap at launch is set at $600k. That gives us room to onboard plenty of users and stress test the system before scaling up. There are progressive limit tiers as Strobe continues to grow in TVL, being a set of valuable training-wheels for the protocol in the early stage.The team will run a full protocol review once we hit 90% of each cap, helping us move to the next level in a smooth, almost invisible way that doesn’t slow user adoption.

Gas

All blockchain transactions require gas to run, and Strobe is no exception. Part of Strobe’s value proposition is removing the complexity of bridging across networks when supplying, borrowing, or collateralizing assets. But behind the scenes, those transactions still need gas to work.

One of the challenges our developers tackled was how users can pre-fund gas for multiple transactions without overpaying, or underpaying and risking failed transactions. Strobe actively monitors the network and adjusts gas estimates in real time to keep things smooth.

At the time of writing, gas estimates are:

• Supply: 0.22 to 0.25 XRP ($0.69 to $0.79)
• Withdraw: 0.34 to 0.36 XRP ($1.07 to $1.13
• Borrow: 0.22 to 0.25 XRP ($0.69 to $0.79)
• Repay: 0.34 to 0.36 XRP ($1.07 to $1.13)

These estimated values will change based on network traffic and the dollar price of XRP.

In rare cases, the network may shift after gas has been estimated. If the gas amount turns out to be too low, the transaction can fail. If that happens, you don’t need to worry; we’ve built a “Transaction Recovery” function directly into Strobe’s interface, with clear written and video guides to help you get back on track.

We encourage users to always keep a little gas in their wallet. It’s an easy mistake to supply 100 percent of your XRP and end up unable to transact. The same goes for Supply and Repay, where gas is paid in the token you are supplying or repaying, not in XRP. Withdraw and Borrow operations do use native XRP for gas.

In a future update, we’ll increase gas estimates by a safety factor of between 1.1 and 1.5 in anticipation of increasing transaction volume. Any unused gas will then be automatically refunded to the user, so you only pay for what is actually used.

Dust

If you’ve used money markets before, you’ll be familiar with the idea of dust. These are small leftover amounts that can appear in your dashboard after actions like repaying or withdrawing.

Dust can show up for a few reasons. One is rounding, another is that interest continues to accrue even during the few seconds it takes to process a repay transaction. So even if you repay your loan in full, a tiny bit of interest might accrue just before the transaction finishes, leaving behind a small balance.

This is expected behaviour and does not affect your account or your funds. One side effect is that your Health Factor might look a little off if you repay and withdraw everything. There’s no need to worry. It will correct itself automatically as soon as you hold a positive balance again.

Dust is normal and nothing to be concerned about.

Liquidity and Interest Rates

Liquidity at launch may be relatively low. That’s normal for any new money market and expected to improve as users begin to supply assets and borrow against them. Early adopters should understand that with lower liquidity, interest rates can be more volatile. Even modest deposits or borrows can shift rates significantly in either direction.

Interest rates in Strobe are variable, not fixed. They adjust automatically based on real-time supply and demand across each asset. When borrowing activity increases and liquidity tightens, rates go up to encourage more supply. When demand slows and excess liquidity builds, rates fall to incentivise borrowing. This model keeps the protocol balanced and dynamic, helping to reduce the risk of illiquidity, debt spirals, or idle capital. It’s a system designed to adapt to market conditions, protect the health of the protocol, and reward users who respond to changes in supply and demand.

Note: We recommend users to take a moment to double-check rates after their transaction completes. The rate shown before you supply or borrow is only an estimate and may change once the action is confirmed on-chain.

Nearly there!

Strobe Mainnet Beta launch is just around the corner, locked and loaded, and ready to go. Whether you’re planning to supply, borrow, or just explore, everything outlined here is designed to give you a clear picture of what to expect on day one.

To be among the first to use the protocol, make sure you’re following @StrobeFinance on X, with notifications turned on. We’ll announce the launch and key links the moment we go live!
