Day 9. A hidden challenge in multichain signing is that “ECDSA” does not mean every chain is identical. Ethereum signs a different kind of payload from Bitcoin. Zcash has different hashing needs. Hyperliquid may share EVM-style signing, but it still needs its own execution context. So @Clearsig_xyz cannot treat remote chains as a single generic bucket. The backend has to prepare chain-native payloads. The @solana program has to bind the right dWallet to the right chain kind. The worker has to request the right Ika signature scheme. The app has to show a human-readable review before any approval happens. That is the engineering line we are walking: generic enough to scale, specific enough to be correct.
Day 8. @ikadotxyz is one of the most important pieces in @Clearsig_xyz multichain architecture. Without it, a “multichain multisig” quickly becomes a set of separate wallets stitched together by UI. With Ika dWallets, ClearSig can bind a remote-chain identity to a ClearSig wallet, then request a chain-native signature after approvals are complete. That unlocks a different model: The user approves from a @solana wallet. ClearSig verifies the approval rules. Ika produces the remote-chain signature. The backend broadcasts to the destination chain. That is a much cleaner foundation than asking users to manage separate key ceremonies for every chain. We are still early, but this is the architecture I believe in.
