Unified Multichain Address Topology: One Wallet, All Chains

Traditional multi-chain trading requires managing multiple browser extensions, custom RPC connections, gas token reserves, and treacherous cross-chain bridge contracts. Fomo reimagines this experience from the ground up:

1. Unified EVM Public Address

Your single Ethereum-compatible address operates simultaneously across Base, Robinhood Chain, Monad, BNB Chain, Ethereum Mainnet, and Arc. Any EVM deposit lands safely in your unified balance.

2. Native Solana Address

Paired with your EVM address is a native Solana SPL public key generated through the same cryptographic Privy MPC sharding session. No extra setup or recovery phrase is needed.

3. Plaintext Key Export

You maintain 100% self-custody. At any moment, you can export your raw EVM hex private key and Solana Base58 private key to verify complete sovereign control over your funds.

Transparent Multi-Chain Fee Structure

Fomo maintains an identical, transparent fee policy regardless of which blockchain you trade on:

  • Standard Spot Swap Rate: 0.45% per trade when using referral code FREEFEES (10% protocol cap discount off base 0.50%).
  • Gas Surcharge: $0.00 on all 7 chains. Fomo covers 100% of execution gas and rent.
  • Micro-Trade Minimum Floor: For small orders under $211, standard tiered minimums apply (under $5: $0.10; $5 to $47.50: 2.0%; $47.50 to $190–$211: $0.95 flat floor fee).
  • Perpetual Contracts (Hyperliquid L1): 0.05% taker fee, cross-margin USDC settlement, available up to 50x leverage for non-US participants.
