Swap

Cross-chain asset exchange with native Bitcoin and Zcash settlement

Sova Swap enables cross-chain token exchange across 50+ blockchain networks with native Bitcoin and Zcash support. Intent-based settlement delivers native assets directly to destination wallets—no wrapped tokens, no bridge IOUs.

The protocol routes swaps through a competitive solver network. Solvers bid to fulfill each intent, ensuring optimal execution pricing.

Settlement: ~15 minutes for most routes. Native asset delivery.

Architecture

Outbound Flow (EVM → BTC/ZEC)

[1] User Input       Token selection, amount, destination address
         ↓
[2] DEX Aggregation  On-chain swap to bridge-compatible asset (if needed)
         ↓
[3] Intent Submission Order submitted to Relay solver network
         ↓
[4] Solver Execution  Winning solver fulfills intent
         ↓
[5] Settlement       Native BTC/ZEC delivered to destination wallet

Inbound Flow (BTC/ZEC → EVM)

[1] Quote Request    User specifies amount and desired output token
         ↓
[2] Address Generation System creates unique deposit address
         ↓
[3] Native Transfer  User sends BTC/ZEC to deposit address
         ↓
[4] Detection        Relay detects deposit, triggers settlement
         ↓
[5] Token Delivery   Output tokens arrive in EVM wallet
