Peg Latency Window (PLW): How Fstocks Discover Price
Synthetic assets like Fstocks (e.g., FTSLA) are designed to track the value of a corresponding tokenized asset such as TSLAx. However, they do not need to match that price instantly. The Fedz architecture intentionally allows short-term deviations while ensuring long-term convergence.
This controlled delay in price convergence is called the:
Peg Latency Window (PLW)
The Peg Latency Window defines the short period during which the market price of an Fstock may differ from the fundamental anchor price reflected in the PLP (TSLAx ↔ FTSLA), before returning to parity.
Why Price Deviations Are Allowed
Traditional AMMs expose LPs to Loss-Versus-Rebalancing (LVR) because arbitrageurs can instantly enforce the true price. Every small price change is exploited with riskless arbitrage, and the LP is systematically “picked off.”
In Fstocks, this mechanism does not exist because:
The PLP is gated and turn-based
Redeeming FTESLA into TSLAx is not instantaneous
Arbitrage flows have bandwidth limits
Fstock minting follows the sequential access mechanism
There is no open, permissionless loop between the AMM and the reference asset
As a result, traders cannot instantly arbitrage FTESLA to match TSLAx. This creates room for short-term price drift in the public FUSD–Fstock pool — and that drift is beneficial, not harmful.
Formal Definition of Peg Latency
Let:
S(t) = the fundamental anchor price of the stock as expressed via TSLAx in the PLP
F(t) = the market price of FTSLA in the public FUSD–FTSLA pool
Define the deviation:
Δ(t)=F(t)−S(t)\Delta(t) = F(t) - S(t)Δ(t)=F(t)−S(t)
and define a small tolerance ε (e.g., 1–2%).
Following a shock at time t0t_0t0, the Peg Convergence Time is:
τconv=inf{τ≥0:∣Δ(t0+τ)∣≤ε}\tau_{\text{conv}} = \inf \left\{ \tau \ge 0 : |\Delta(t_0 + \tau)| \le \varepsilon \right\}τconv=inf{τ≥0:∣Δ(t0+τ)∣≤ε}
The Peg Latency Window (PLW) is the typical or expected value of τconv\tau_{\text{conv}}τconv for meaningful shocks (where |Δ| exceeds ε).
In plain language:
The Peg Latency Window is how long it usually takes for Fstocks to realign with their underlying asset after a price shock.
Why PLW Matters for LPs
Inside the Peg Latency Window:
FTESLA may trade slightly above or below TSLAx
External arbitrageurs cannot instantly correct the price
Order flow consists mostly of uninformed traders
LPs often buy Fstocks at a discount or sell them at a premium
Arbitrageurs must take directional risk, not riskless profit
This breaks the assumptions behind the classical LVR model, which relies on:
Instant access to the reference asset
Ability to continuously rebalance to neutral exposure
Immediate arbitrage between AMM price and true price
Since these conditions do not hold, arbitrageurs cannot impose the “true price” on the public pool, and LPs are not systematically exploited.
Instead of suffering guaranteed LVR, LPs operate in a regime where:
Short-term deviations work in their favor
Arbitrage becomes risky rather than free
LP losses are no longer mechanically equal to arbitrage profits
The expected LVR cost collapses compared to traditional AMMs
Long-Term Price Discovery Still Holds
Although the public pool price can drift inside the Peg Latency Window, The Fedz ensures long-term accuracy:
The PLP maintains the canonical peg between TSLAx and FTSLA
Sequential access and turn mechanics gradually repair deviations
Arbitrageurs eventually close the gap once access becomes available
FUSD printing and supply adjustments deepen liquidity over time
Combined mechanisms guarantee Mean Reversion to the Anchor Price
Thus, the Fstock price path looks like this:
Short term: noisy, temporarily misaligned
Medium/long term: convergent, anchored, fundamentally correct
This allows Fstocks to replicate the economic exposure of a real stock while avoiding the structural losses that plague traditional AMM LPs.
Summary
Fstocks track real tokenized stocks over the long term.
Short-term deviations are intentional and necessary.
The interval before convergence is the Peg Latency Window (PLW).
During this window, LPs often gain from noise-driven order flow.
Arbitrageurs cannot execute riskless loops, breaking the usual LVR mechanics.
Long-term price discovery is preserved via the PLP and turn-based rebalancing.
The Peg Latency Window is the core mechanism that allows Fstocks to remain stable, track real-world prices, and avoid the loss-versus-rebalancing trap that makes traditional AMM-based synthetic assets unprofitable to support.
