Sera is the exchange layer stablecoins were missing. It provides atomic cross-border swaps between 600+ stablecoins denominated in 120+ currencies — non-custodial, zero protocol fee, sub-300ms quote latency.

## Key stats

## How it works

1. **Quote** — The SOR engine aggregates live rates from 50+ banks, 10+ PSPs, and 10+ FX houses to find the best path.
2. **Sign** — The user signs an EIP-712 intent off-chain. No gas required at this step.
3. **Settle** — Sera submits the transaction on-chain. The swap completes atomically in one block.

## Who uses Sera

- **Cross-border payment platforms** — Replace slow, expensive correspondent banking with on-chain atomic FX.
- **Stablecoin issuers** — One Sera integration unlocks 600+ stablecoins, 70+ MMs, PSPs, rails, and exchanges.
- **Liquidity providers** — Earn FX spread yield across 30,000+ corridors from a single deposit.
- **AI agents** — Use Sera's MCP server at agents.sera.cx/mcp for autonomous FX settlement.

## Why not bridge protocols?

Bridge protocols (CCTP, LayerZero, etc.) move the same token across chains. Sera converts currencies. If you need USDC on Polygon, use a bridge. If you need USDC converted to BRL, IDR, MYR, or 100+ other currencies, use Sera.
