We recently posted a Unified Ledger app proposal which gained both remarkable support and significant pushback within our ecosystem sparking a hot debate on multiple platforms and channels. It was quite surprising to uncover a fair bit of opposition and allegations based not on constructive criticis…

I understand the difference between chain metadata and XCM. My argument was: to support cross chain DeFi we will need a much larger set of XCM messages (like deposit DOT into an AMM, borrow USDT, or swap USDT for DOT with a maximum price of Z, deposit DOT into liquid staking and get LDOT). As the co…

We can compare Pallet transactions to XCM transactions: Pallet transactions: Meaning determined by pallet and runtime authors. Meaning can change with every upgrade of the chain; no limitation in frequency. Unversioned. XCM transactions: Meaning determined through RFC process and community inp…

I am hearing two conflicting things from people working on Polkadot on the idea of using XCM as not just cross chain messaging but a generic user interface: XCM is a better way to interact with parachains and we should push people to just use it XCM won’t change much (1/year) and because of that w…

XCM will never be exhaustive XCM is unlikely to be able to cover all functionality offered by all chains but is eventually likely to cover most common functionality of chains. Governance is a good example and likely should be covered by XCM in the not-too-distant future. I fear that attempting t…

[image] gavofyork: There would be a huge amount of duplicated work. Metadata is fine generalising the signing process over many chains, but it doesn’t help much with creating UIs for things like chain-agnostic defi and governance. Yes, I agree. Hence it’s important to not look at XCM as the s…

While I’m generally against pushing anything as being a “saviour”, XCM is designed to abstract all sorts of operations over chains. It already does a lot more than “sending and receiving tokens” and will evolve over time to cover a lot of use-cases. Eventually its coverage will likely become complet…

Let’s recap what we’ve stated so far. Here are the issues we see with the integration of the ledger and other cold wallets: Frequent runtime updates The need to have an application for each parachain Inability to verify large transactions on the small screen of the Ledger device Inability to valid…

We had this week some good discussions around the topic. We also directly spoke with Zodax and other people of the ecosystem. We will go into the direction of merkelized metadata. There will be a new ledger app that will stream the metadata as proofs to the device to stream decode the extrinsic. For…

I think this GameBoy solution (links courtesy of @rich ) is futureproof and is highly resilient because you can’t trust existing and future supply chains: https://www.gamewallet.gg/ [image] Your Old Game Boy Can Now Be Turned Into a Bitcoin and Ethereum Hardware... Crypto startup Keyp is…

This is cool, but again, the problem with new solutions like this one and Polkadot Vault (which is great!) is that tons of people already use Ledgers and aren’t eager to have a separate hardware device. I use a Ledger myself, and I’d strongly prefer to be able to use it with Polkadot/Kusama ecosyste…

Is the “key-less account” here the same as what was proposed/canvased here (AIP-61):
