Fee Model

`source: 'sdk'`	0.03%	Bots, protocols, developers
`source: 'ui'`	0.05%	Frontend users via vaea.fi

Fee Calculator

Total cost = VAEA fee + swap cost (synthetic routes only). Use maxFeeBps in SDK to auto-reject if fee exceeds your threshold.

Direct Route Example

text

Borrow: 10,000 SOL (direct from Marginfi)
  VAEA fee:      0.03% = 3 SOL
  Swap cost:     0 SOL (no swap needed)
  ─────────────────────────────
  Total cost:    3 SOL (0.03%)
  You repay:     10,003 SOL

Synthetic Route Example

text

Borrow: 10,000 mSOL (synthetic via Sanctum)
  VAEA fee:        0.03% ≈ 3 SOL equivalent
  Swap SOL→mSOL:   ~0.03% ≈ 3 SOL
  Swap mSOL→SOL:   ~0.03% ≈ 3 SOL
  ─────────────────────────────
  Total cost:      ~9 SOL (~0.09%)
