Pools on Flare

stXRP Pool (Maturity: Mar 05, 2026)

sFLR Pool (Maturity: May 17, 2026)

Yield Trading Concepts

• PT (Principal Token): Redeemable 1:1 for underlying at maturity. Trades at discount = fixed yield.
• YT (Yield Token): Receives all yield until maturity. High leverage on yield.
• IBT (Interest Bearing Token): The yield-bearing asset (stXRP, sFLR).
• Pool: Curve-style AMM for PT ↔ IBT swaps.

Key Interfaces

PT Token (ERC-4626 style)

function depositIBT(uint256 ibts, address ptReceiver, address ytReceiver) returns (uint256)
function redeemForIBT(uint256 shares, address receiver, address owner) returns (uint256)
function previewDepositIBT(uint256 ibts) view returns (uint256)

Pool (Curve-style)

function exchange(int128 i, int128 j, uint256 dx, uint256 min_dy) returns (uint256)
function add_liquidity(uint256[2] amounts, uint256 min_mint) returns (uint256)
function remove_liquidity_one_coin(uint256 amount, int128 i, uint256 min) returns (uint256)
function get_dy(int128 i, int128 j, uint256 dx) view returns (uint256)
// coins: [0] = stXRP (IBT), [1] = PT

Usage Examples

# Check pool stats
/spectra status

# Check your balances
/spectra balance

# Deposit 10 stXRP → get PT + YT
/spectra deposit 10 stxrp

# Swap 5 PT for stXRP
/spectra swap pt stxrp 5

# Add 10 stXRP to LP
/spectra lp add 10 stxrp

Routing Guide

Don't use when...

• Staking FLR for sFLR (use /sflr)
• Managing LP positions (use /lp)
• Simple token swaps (use /swap)

Use when...

• Trading yield on Spectra Finance (PT/YT tokens)
• Splitting yield-bearing tokens into principal and yield
• Checking Spectra pool APY and TVL

Edge Cases

• stXRP pool maturity: Mar 05, 2026 — PT redeemable 1:1 after
• sFLR pool maturity: May 17, 2026
• PT trades at discount before maturity (discount = fixed yield)
• YT value decays to 0 at maturity — time-sensitive

Success Criteria

• Status shows pool APY, TVL, and maturity countdown
• Deposit returns PT + YT token amounts
• Swap executes in Curve-style AMM with expected slippage
