arXiv:2610.30183v1 Announce Type: new Abstract: Mainstream Web3 SDKs (e.g., ethers.js, viem) bundle three coupled assumptions: an account-based ledger, a single secp256k1 signer, and input-selection-free transaction construction. These assumptions fail once a chain adopts an extended-UTXO model (here, the Cell model on Nervos CKB), and once the wallet population spans heterogeneous cryptographic primitives (secp256k1, WebAuthn, Schnorr).
