The FTSO page provides a complete epoch-by-epoch history of your FTSO delegations on both Flare and Songbird.

#Purpose

This page solves a critical problem that most blockchain explorers cannot: accessing historical delegation data from old epochs.

Most explorers rely on current blockchain state, which gets pruned over time. Once an epoch is old enough, it becomes impossible to query which providers you delegated to or how much vote power you had. The FTSO page reconstructs this history by replaying historical on-chain events (Transfer and Delegate events), allowing you to see your complete delegation history—even for epochs from years ago.

#Why This Matters

• Historical Analysis: Review your delegation strategy and provider performance over time
• Reward Verification: Match rewards to specific epoch delegations
• Performance Tracking: Calculate your actual APR across different providers and time periods

#What you will see

#Delegation History Table

The main table displays one row for each epoch where you had delegations. Each row shows:

• Epoch Number — The FTSO epoch identifier
• Network — Flare or Songbird
• Start Date / End Date — The epoch's time window (approximately 3.5 days)
• Provider 1 & Provider 2 — The data providers you delegated to (up to 2 per epoch)
• Allocation (%) — The percentage of vote power allocated to each provider
• Vote Power — Your total vote power for that epoch
• Reward — Tokens earned from that epoch's delegations
• USD Value — Historical USD value of rewards
• APR — Estimated annualised return rate for that epoch

Provider information includes logos and names when available.

#Search & Filtering

Find specific delegation data quickly using the search bar and filters:

Search Bar — Type-to-filter across all columns including provider names and addresses.

• Network: All, Flare only, or Songbird only
• Epoch: View all epochs or select a specific epoch number
• Provider: Filter by specific provider name
• Date Range: Select start and end dates
• Vote Power Range: Filter by minimum and maximum VP amounts
• Reward Range: Filter by reward amounts earned

#Visualisation Options

Switch to chart view for visual insights into your delegation history:

Vote Power Over Time — Line chart showing your total vote power across epochs. Helps visualise when you increased or decreased your delegation amounts.

APR Over Time — Track your annualised return rate per epoch. Identify which time periods and provider combinations performed best.
