How It Works

Settlement Layer Model

S&F separates settlement from execution.

The protocol does not try to be the fastest trading venue. It keeps the canonical accounting for perpetual exposure: collateral, issuance, redemption, funding rate, oracle rounds, and position-token balances.

Trading can happen on top of that settlement layer.

Execution can be fast and plural. Settlement should be neutral and canonical.

What the base layer does

ETC and the S&F contracts are responsible for the source of truth:

  • who owns position shares;
  • how much collateral backs the pool;
  • which liquidity is active;
  • what oracle price is used for settlement;
  • how funding rate and PnL affect the system;
  • how many synthetic tokens balanceOf should display.

This is the settlement layer.

What markets do

Markets provide execution.

An AMM, app frontend, market maker, or another venue can let users trade S&F tokens. Those venues do not become the source of truth for the position. They only move the token.

The position remains portable because the position is represented by a token.

Example

Alice mints S-BTC through OTC settlement.

After settlement, Alice holds S-BTC tokens. She can keep them, transfer them, deposit them into a market, or sell them to Bob.

If Bob buys those tokens in a secondary market, the S&F protocol does not need to create a new position. Ownership moved, but the settlement layer still defines what the token represents.

Why this matters

This model lets S&F keep slow, neutral settlement on ETC while allowing faster execution wherever liquidity exists.

The base layer is not the matching engine. It is the court of record.
