UPDATE: Refunds are processed in full, with an extra 10% cashback. The Solana contract has been updated. We haven't seen any further related activity, and we're constantly monitoring it. If your Solana card balance was withdrawn a few hours ago, we've restored the full amount and added 10% cashback on what was withdrawn. Open the app and cross-check your balance. Here's exactly what was affected and what wasn't: 1. This was limited to card contracts on Solana holding balances added through Avici's Top Up flow. 2. Your regular Avici Solana and EVM wallets were never affected. Those wallets are self-custodial and stayed under your control the entire time. 3. EVM card balances, onramps, offramps, and swaps were not affected. 4. Funds outside these Solana card-balance contracts were never exposed. We made a very deliberate choice to keep your Avici wallet separate from your card balance. It's why you have to manually Top Up before spending. Combining both would've made the app easier to use, but we didn't do it because we believed keeping them separate was safer. That separation is why this stayed limited to the affected Solana card contracts while wallets and everything else in Avici stayed untouched. That doesn't make what affected users went through okay. We're sorry for the stress and uncertainty this caused. We're not proud that this happened. We are proud that Avici is built onchain, where balance movements are immediately visible and independently verifiable instead of hidden behind a private ledger. In traditional fintech, the number shown in an app can stay unchanged while what is happening underneath remains invisible. Here, anyone could see the movement onchain as it happened. We're pushing the frontier of onchain finance, and that road was never going to be easy. Moments like this are painful and humbling, but they show us what has to improve and will make Avici stronger. We're not stepping back. We're going to keep pushing forward. Rain, our card issuing partner, covered all reimbursements in full. Huge credit to their team for moving quickly, working closely with us, restoring every affected balance, and fixing the issue. We'll publish a full postmortem once the investigation is complete. And a huge thank you to every partner who jumped in immediately to help us through this: @solana, @raincards, @Helius, @MetaDAOProject, @zeroshadow_io, and @asymmetric_re. Thank you for staying with us through the uncertainty and stress this caused today.

UPDATE: All affected card balances will be refunded in full Earlier today, our card-issuing partner, Rain, identified a vulnerability in an version of a Solana card contract used by Avici and a small number of other programs. The contract has now been upgraded across all programs, and no further unauthorised activity has been observed. Avici wallets and card balances are separate. Avici wallets are self-custodial and remain under users’ control. When users top up their cards, funds move into a separate Solana contract that holds their card balance. Only this contract was affected. Note: Funds held in Avici’s Solana and EVM wallets are safe and were not affected. Our current reconciliation shows that 1,685 users were affected, representing $500,859.22 in card balances. Every affected user will have their card balance refunded in full. We remain in close contact with our card-issuing and security partners and are monitoring the remediation closely. Avici has also filed a report with the FBI’s Internet Crime Complaint Center. We are deeply sorry for the concern and inconvenience this has caused.

We’re aware of an issue affecting card balance withdrawals and are closely monitoring the situation. We’re working directly with all relevant partners to resolve it and will share updates as soon as we have more information.

many wallets charge 0.8-1% every time you swap. on $1,000, that’s $8-$10 gone. on Avici, its zero swap fees and we cover the network fees too. so more of your money stays yours. https://t.co/LUwNhBGwcR
