Implement UI from Figma designs via MCP with a closed-loop pixel-parity check. Extract exact values (never eyeball), translate to SwiftUI, then render→diff→fix against the Figma export until it matches. Use when implementing or auditing UI against Figma.

Vultisig supports 40+ blockchains using threshold signature schemes (TSS) with three cryptographic algorithms.
| Algorithm | Library | Curve | Chains |
|---|---|---|---|
| ECDSA | godkls | secp256k1 | Bitcoin, EVM, THORChain, Cosmos, Ripple, Tron (34 chains) |
| EdDSA | goschnorr | Ed25519 | Solana, Cardano, Polkadot, Ton, Sui (6 chains) |
| ML-DSA | vscore | ML-DSA-44 | Post-quantum support (future) |
BlockChainService (Core/Services/BlockChainService.swift) coordinates chain-specific operations:
