Why Sera¶

Traditional foreign exchange operates through a fragmented network of banks, brokers, and dealers. While this system moves $9.6 trillion daily, it comes with significant structural limitations. Sera addresses these by bringing FX trading on-chain.

Advantages Over Traditional FX¶

Transparency¶

Traditional FX is an over-the-counter (OTC) market — pricing is opaque and spreads vary by counterparty. Sera uses a central limit order book (CLOB) for fair price discovery and matching, ensuring consistent pricing for all participants.

Non-Custodial¶

In traditional FX, your funds sit with a broker or prime brokerage. If the counterparty fails, your capital is at risk. On Sera, funds are held in audited smart contracts on Ethereum — not by any intermediary. You retain full control and can withdraw at any time, even if Sera's servers go offline.

24/7 Settlement¶

Traditional FX settles on a T+1 or T+2 basis through CLS Bank or correspondent banking networks, and only during banking hours. Sera settles trades on-chain in real time, 24 hours a day, 7 days a week. No settlement risk, no weekend gaps.

No Intermediaries¶

A traditional FX trade can pass through multiple intermediaries — dealers, prime brokers, custodians, and settlement agents — each adding cost and delay. Sera removes these layers. Trades are matched off-chain and settled directly on-chain between counterparties.

Permissionless Access¶

Traditional FX markets have high barriers to entry: minimum account sizes, credit checks, and geographic restrictions. Sera is open to anyone with an Ethereum wallet. No minimum balance, no application process.

Verifiable¶

Traditional FX relies on trust — you trust your broker's quoted price, your custodian's balance sheet, and your settlement agent's process. On Sera, all smart contracts are open source. Settlement logic, balances, and trade history are independently verifiable on-chain.

What Makes Sera Unique¶

Beyond the general advantages of on-chain trading, Sera introduces capabilities that don't exist in traditional FX or other on-chain exchanges.

Smart Order Routing (SOR)¶

Sera's Smart Order Router finds the best execution path across all available pairs. If you want to swap GBP to SGD but the direct pair has thin liquidity, SOR can atomically route through USD — e.g. GBP → USD → SGD — in a single transaction, at the best available price. All legs settle atomically: either the entire route executes, or none of it does.

Virtual Liquidity¶

Virtual Liquidity lets market makers place orders across multiple trading pairs backed by a single shared budget. Instead of locking separate collateral for EUR/USD, GBP/USD, and SGD/USD, a single USD deposit can back all three. When one order fills, the remaining orders are automatically adjusted. This dramatically improves capital efficiency — a capability that doesn't exist in traditional FX or other on-chain exchanges.

Direct Non-USD Settlement Pairs¶

Traditional FX routes almost everything through USD. A EUR → SGD trade typically executes as EUR → USD → SGD, with two spreads, two settlements, and the associated costs. Sera supports direct cross-currency pairs — EUR/SGD, GBP/JPY, AUD/BRL, and hundreds more — so you can trade and settle directly without the USD leg, reducing costs and complexity.

Gasless Swaps¶

Swap users don't need ETH for gas fees. Costs are factored directly into the quote, so you can trade using only stablecoins — no wallet top-ups, no failed transactions from insufficient gas.

MEV Is Not an Issue¶

On Sera, MEV is not a practical trading issue in the way it is on on-chain AMMs. Price discovery and matching happen inside Sera's Web2 CLOB matching engine, not in Ethereum's public mempool. Ethereum is used as the final settlement layer only.

Because orders are matched off-chain rather than exposed as public marketable swaps on-chain, searchers do not get the usual opportunity to front-run or sandwich user flow. For swaps, users still sign exact execution bounds such as maxInputAmount and minOutputAmount, so settlement either happens within those signed limits or fails.
