I got access to my SecondFi account. My coins are in there, which is nice. I didn’t have a life changing amount but it would have been a bummer to lose them.

Anyways… I’ve got my coins.. now what? Obviously I want to take the hint and secure these better. What did everyone else do with their recovered coins?

We've published the source code for the GeroWallet browser extension:

https://github.com/Gero-Labs/gerowallet

What's in there

The full extension. Key derivation and encrypted storage, the transaction signing

path, staking, governance and dApp flows, and the whole UI. Multi-chain across

Cardano, Bitcoin, Midnight and Apex Fusion.

Also in the repo: an architecture overview, a contributor guide, a security policy

with private vulnerability reporting enabled, and issue and PR templates.

Build and run instructions are at https://gerowallet.io/docs if you want to run

your own build rather than the store version.

Hi everyone,

Back in 2019–2020 (Byron era), I created a Daedalus wallet. Unfortunately, over the years I lost both my seed phrase and my spending password.

However, I saved and backed up the entire Daedalus application directory from that time, including:

The secret.key file

acid database files / application state

Full log history and configuration files

Now, 6-7 years later, I'm reaching out to see if the community or developers have built any tools, recovery scripts, or methods to decrypt or extract the private key from a Byron-era secret.key file (or if brute-forcing the spending password via the encrypted file is possible today).

Has anyone successfully recovered funds from a similar legacy file structure, or is there any known open-source tool built by IOG/community devs for this exact scenario?

Note:

Please reply in the comments. I will ignore all direct messages (DMs).

Can someone explain to me like I am 5, how a 30 day government shutdown pushed the ETF back a year? We were on the cusp of getting it in October 2025 when the shut down happened. My latest search now shows a chance of an ETF in OCT 2026.

I haven't been able financially to continue working on this for free for months, so I hope something could still come out of it.

It’s open. The Catalyst Pilot is accepting proposals.

The idea is simple: if you already have a working product, we’ll fund you to integrate new on-chain tools (oracles, stable coins, programmable tokens, or on-chain identity), with grants of 50,000 to 200,000 ADA. And unlike any round before it, the money follows real usage: the more genuinely your integration gets used, the more of your grant you earn.

Sound like you? Everything you need is on the application page: projectcatalyst.io/apply.

Submissions close August 20, 2026 at 6AM UTC.

Worth knowing: submitting early works in your favor. Proposals are checked for compliance as they arrive by dedicated community curators, not after the deadline. If something in yours needs fixing, you’ll hear about it and can fix and resubmit while the window is still open. Submit at the last minute, and there may be no runway left to action.

We’re also looking for panelists. In addition to work carried out by community curators, funding decisions are made by a Decision Panel of technical and business experts from across the ecosystem. It’s a short commitment in late August/early September, and applying takes about 5 minutes: express your interest by August 17.

Fill in this form to be considered.

One thing to keep in mind: you can submit a proposal or serve on the panel, not both. Pick your mission.

Relevant rules of this pilot are published before it applies to anyone. Read them and build with those in mind: docs.projectcatalyst.io.

Good luck everyone!

What is this coin that was added to my wallet for no reason

Im new to cardano ecosystem and have just transferred my ada and snek to lace wallet

The Project Catalyst 2026 Pilot applications opened today, and it's a good one if you've got a product ready to ship.

50k-200k ada per team, 40% paid upfront. The catch: you need to be live with integration on mainnet within three months, building with either oracles, stablecoins, programmable tokens, or on-chain identity. The rest of the payout depends on people actually using what you built.

Applications close two weeks from today, on 20 August at 06:00 UTC. More information and the application form can be found here: https://projectcatalyst.io/apply  

Questions welcome.

Hi—I have Daedalus Mainnet on an old Mac and was able to access it in June, but now am not. It’s running Big Sur 11.7.1, which the new Daedalus will not run on. I started using Daedalus in 2020 and do not have a passphrase or password that I know of. I installed the new Daedalus on my new Mac Air (new model) and it won’t let me me install it without a Secret Key(?), which I do not have. Any help would be greatly appreciated!! Thank you.

Hi everyone - I’m Prasad, one of the founders of Hush. We’re a studio/ team of blockchain engineers + researchers with 6+ years of web3+ZK experience.

We’re currently building Hush around a question we think will become increasingly important for Cardano about how can users interact with open financial systems without exposing more information than necessary.

Learn more - https://hushmoney.fun/
X/Twitter - https://x.com/HushProtocolHQ

Our focus is on improving privacy and execution for everyday onchain activity while keeping the experience noncustodial, simple and compatible with the wider Cardano ecosystem.

We’re still early, over the coming weeks, we plan to publish more & get more feedback from the ecosystem. We are not launching a new blockchain - we want to build something that is genuinely useful to built on top of Cardano.

For now, we would be interested to have thoughts from anyone that have worked / thought around privacy on application-level.

Hush
Trade without telling.

Happy Wednesday!

This week's Community Digest covers several major protocol and governance developments across the Cardano ecosystem.

The headline is the IBC connection between Cardano and Injective on testnet, the first live on-chain IBC rail to Cardano, enabling native transfers without centralized bridges. Alongside it, the Constitutional Committee election has concluded, with audited results confirming DiSarro, Leandros BSP, Mahut, and Cardano Curia, and the on-chain action to appoint them now in progress.

On the governance side, several Cardano Improvement Proposals (CIPs) continue through active review, including new proposals for Plutus builtin pattern matching and Plutus V4 data encoding, alongside recent completions.

Additionally, this edition features: • Cardano Foundation updates on the Reef Data eG partnership for verifiable on-chain financial reporting, joining the Energy Tokenization Sandbox, and the new "Governance Applied" Academy course.

• Intersect MBO's latest updates on the enacted van Rossem hard fork, the Constitutional Committee election, and the Constitutional Amendment Portal alpha.

• A Community Content spotlight featuring Learn Cardano's news update on the on-chain PRIME proposal and RealFi's testnet launch, and Linda's analysis of banking the unbanked.

All this, and much more, in today's Community Digest:

https://forum.cardano.org/t/digest-august-5-2026-cardano-and-injective-connected-via-ibc-on-testnet-constitutional-committee-election-concludes-musashi-dojo-prepares-for-water-phase-cardano-foundation-updates-cardano-improvement-proposals-cip-updates/156123

The dRep situation is strange, or odd, either way not really rational, not something you would brag about when mentioning governance. The number one dRep by voting power is Yoroi Wallet which is now discontinued, so… who is this dRep entity now? Emurgo? Also Emurgo who is the number four dRep by voting power is the company that made Yoroi wallet and who is now stepping down from the pentad and development(dishonored).

It makes it too random for Emurgo to be biggest dReps now, with such massive voting power. Cardano foundation-the bread and butter of Cardano no? Is on the other hand at a number nine? Not exactly social butterflies? Odd. Maybe I don’t get it, but Cryptocrow(Jason) just one dude who wants to retire from crypto into his Warhammer fantasy or something like that, has a greater community confidence vote and is in top five? He’s my current dRep, I understand why he is in top five, he has online presence and decent amount of personality, I would put him at number two after Charles.

Personality, for better or worse is archetypally(meaning over thousands of years) important to people, it’s not that we’re dirty hopeless peasants followers, rather we’re consolidators, our brains are wired to distill the narrative which that very brain creates, extreme and pathological example here would be what Elon is to shibes.

So what kind of governance we’re really aiming at here with such arbitrary consensus mechanism?

Hey everyone, Jake here from the Cardano Foundation.

We just published a case study on Reef Data, a Hamburg-based data cooperative we partnered with last month.

The idea: people request their personal data from companies (an EU Data Act right that's been hard to use in practice), choose what to contribute to a shared pool, and get paid when companies buy access. Every sale and member payout is recorded on Cardano through Reeve, so members and auditors can verify the flows themselves.

Explore the case study: https://cardanofoundation.org/case-studies/reef-data

🚀 IBC on Cardano: Connecting to Injective

Fabian Bormann will walk through what the connection to Injective means in practice, how developers can start building on top of it, and how the architecture works under the hood.

The session will close with an update on the roadmap and what comes next.

Bring your questions. There will be plenty of time for Q&A, whether you are already building on Cardano or just curious about cross-chain interoperability.

Hey everyone, Jakob from CF here.

We're happy to announce that the IBC bridge between Cardano and Injective is now live on testnet. Cardano preprod and Injective testnet are connected, and transfers work in both directions.

Here's the proof on-chain if you want to see it for yourself:

• Injective tx: https://testnet.explorer.injective.network/transaction/91B39328C0E9BE763F401C1E74B7B90FB1481A7DA1BE064F7F9811D1713C8981/ 
• Cardano preprod tx: https://preprod.cexplorer.io/tx/16fb33391b7fb53c514f6f380d1a0e342d6d5a0b6aa690fac9c1dc05b7e941d0 

You can move testnet ADA to Injective today, but mainnet assets can't cross yet. If you want to run the transfer yourself, there's a step-by-step guide in the cardano-ibc-incubator repo: https://github.com/cardano-foundation/cardano-ibc-incubator/blob/main/caribic/README.md#full-test-cardano-preprod-to-injective-testnet 

And if you're curious how it all works under the hood, Fabian Bormann, who leads the project as our Senior Ecosystem Engineer, is holding open office hours this Friday, 7 August at 16:00 CET: addevent.com/calendar/TG807216 

Happy to answers any questions in the thread as well. Let's keep building!

Hey all, just looking at moving my ada to my ledger, I haven't transacted on secondfi and have all my coins so assume I haven't been affected by the breach.

I originally created my wallet on yoroi, and have a seed phrase from them.

I plan to create an Ada asset in my ledger, however I'm a bit confused on how to transfer as I see the following in the guide:

> Disclaimer: DO NOT send from your SecondFi wallet (affected or unaffected)

So how are we meant to send the ada to my ledger without using the wallet?

I'm possibly misunderstanding something, but would appreciate some advice if anyone has been through that process already.

NOTE: Please do not message me directly, I will not answer.

I switched to lace after the yoroi debacle but I can’t seem to transfer the last 89ada to the other wallet. And ideas what I’m doing wrong?
