# Sera Technology

**The settlement engine stablecoins were missing.**

Sera's architecture is a four-plane system engineered for cross-border stablecoin FX.

## 1. Virtual Liquidity

A single LP deposit earns spreads across 30,000+ corridors without deploying capital separately into each pair. Capital efficiency exceeds 100× vs traditional AMMs.

- LPs set bid/ask spreads on corridors they choose
- No impermanent loss in either deployment model (matched or unmatched)
- Withdrawal is instant, gas-free, no lock-up

## 2. Smart Order Routing (SOR)

The SOR discovers the cheapest path across all live liquidity pools in a single on-chain transaction.

- Splits settlement into optimal sub-legs
- Executes atomically — reverts entirely if any leg fails
- MEV-resistant: path details hidden until after trade

## 3. Intent-based Execution (EIP-712)

Users sign a typed intent off-chain. Sera finds the optimal path and submits the transaction.

- Gasless user experience — Sera pays gas
- EIP-712 typed signatures for security and auditability
- Intent describes what, not how — routing is protocol-side

## 4. Non-custodial Settlement

Stablecoins stay in the user's wallet at all times. The protocol only routes flow under instruction from signed intents.

- emergencyWithdraw() escape hatch on all vaults
- Circuit breaker halts trading if oracle deviation exceeds 2%
- On-call monitoring responds within 30 seconds
