The Cold Start Problem¶

New exchanges face the same circular problem: traders want liquidity before they trade, and liquidity providers want order flow before they commit capital. In on-chain FX, that loop is even harder to break because liquidity is fragmented by corridor. EUR/USD, USD/SGD, GBP/USD, and more exotic pairs each need their own dependable depth profile.

This means Sera cannot rely on one mechanism to do everything. The protocol needs a way to launch corridors with immediate executable liquidity, while still creating room for competitive market makers to tighten spreads over time.

Why It Is Harder in FX¶

Spot crypto venues can sometimes get away with bootstrapping around a small number of flagship pairs. FX is different. Each corridor has its own natural users, treasury flows, volatility pattern, and market-maker appetite. A venue can look healthy on one pair and still be functionally illiquid on the next ten.

That is why Sera treats liquidity as a layered system rather than a single pool problem. The goal is not just to show TVL. The goal is to make real size executable, corridor by corridor, while letting spreads improve as organic flow arrives.

Sera's Liquidity Model¶

Sera's target liquidity model combines two complementary sources of liquidity:

The CLOB is where active participants compete. It creates the best available inside price and keeps spreads honest. In the planned full model, FCICAMM sits behind that competitive layer as structured passive inventory, making sure Sera still has executable liquidity when a corridor is new, market makers are thin, or order sizes exceed the immediately available book.

In normal conditions, traders should execute against the CLOB first because that is where competition lives. In the target design, FCICAMM becomes more important at the edges: new corridors, larger tickets, or periods when active liquidity temporarily thins out.

How Liquidity Can Build Over Time¶

1. FCICAMM rollout: Once introduced, FCICAMM can provide reliable backstop liquidity so a corridor is tradable from the start.
2. Market-maker entry: Professional makers quote tighter inside spreads on the CLOB once they see executable flow.
3. Volume concentration: More users route into the corridor because pricing improves and fills become more predictable.
4. Depth compounding: The CLOB handles the competitive inside market while FCICAMM can continue to absorb excess size and support continuity.

This is how Sera plans to address the cold start problem without depending only on incentives or hoping passive liquidity magically discovers price on its own.
