Could you build this?
No A self-custodial wallet supporting 35+ blockchains with an offline Rust cryptographic signing kernel has zero room for error, as any implementation flaw results in total loss of user funds.
What it would actually take: The architecture requires a hardened Rust cryptographic library compiled to WebAssembly or native targets using audited crates (such as k256, ed25519-dalek, bip39) alongside custom transaction encoders for Bitcoin, EVM, Solana, and Substrate networks. The hardest challenges are writing byte-for-byte correct transaction serialization, handling unique derivation schemes safely, and securing the signing environment against side-channel or memory-dump attacks. Building this requires senior blockchain protocol engineers and formal third-party cryptographic security audits.
